CHAGARES, Circuit Judge.

       For nearly six years, appellant Scott Hornick led a group that burglarized retail

establishments up and down the East Coast and transported the stolen goods across state

lines for unlawful resale. In February 2010, a federal jury convicted Hornick of multiple

counts related to his participation in the burglaries. Hornick contends that his conviction

was in error because the Government violated his rights under the Interstate Agreement

on Detainers and because he was prejudiced by trial testimony about his appearance on

the television program America’s Most Wanted. Hornick also challenges the conspiracy

count charged in the indictment and objects to the District Court‘s severance of certain

conspiracy evidence in its jury charge. Finding no merit in these claims, we will affirm.

                                              I

       We write solely for the parties‘ benefit and recite only the facts essential to our

disposition. From August 2001 to July 2007, Hornick orchestrated a sustained spree of

burglaries in 13 East Coast states. Shortly after escaping from prison in August 2001, he

reconnected with a prior acquaintance, Vallin Malcom, who sold stolen merchandise on

the black market. Working with Rene and Rolando Moran (hereinafter the Moran

brothers), Hornick burglarized high-end electronics stores and sold the stolen goods to

Malcom. Hornick and the Moran brothers were arrested in New Jersey in October 2002

after robbing a Circuit City electronics store and leading police on a high-speed car

chase. After giving police a false name and fake identification, Hornick was released on

bail. He immediately roped two prior acquaintances, Jerry Todisco and Sasha Ingardi,

into committing burglaries with him. Jerry‘s brother, Anthony Todisco, joined the group

                                              2
soon thereafter. The collaborators operated just as before, burglarizing high-end

businesses and reselling the stolen goods to Malcom. The Todisco brothers participated

until they were arrested in December 2004. Hornick and Ingardi operated until Delaware

state police arrested them in July 2007.

       A federal grand jury returned a ten-count superseding indictment against Hornick

on June 11, 2009, a second superseding indictment on October 8, 2009, and a third

superseding indictment on January 3, 2010. Count 1 of the third superseding indictment

alleged conspiracy to commit interstate transportation of stolen property in violation of

18 U.S.C. § 371; counts 2 through 7 alleged six distinct violations of the statute

prohibiting interstate transportation of stolen property valued over $5000, 18 U.S.C. §§

2314 and 2; count 8 alleged conspiracy to burglarize pharmacies in violation of 18 U.S.C.

§ 2118(d); and counts 9 and 10 alleged pharmacy burglary in violation of 18 U.S.C. §

2118(b). The District Court held a trial from February 8 to 22, 2010. The jury found

Hornick guilty of the crimes charged in counts 1 through 8 and found him not guilty on

the crimes charged in counts 9 and 10. The District Court sentenced Hornick to 27 years

in prison, followed by three years of supervised release, and set restitution at

$1,788,291.58. Hornick timely appealed.1

                                              II

       Hornick‘s first claim is that he was entitled to dismissal of all charges against him

because the Government violated his rights under the Interstate Agreement on Detainers

1
  The District Court had jurisdiction under 18 U.S.C. § 3231. We have appellate
jurisdiction under 18 U.S.C. § 3742(a) and 28 U.S.C. § 1291.

(―IAD‖), 18 U.S.C. App. 2, §§ 1-9. To analyze this claim, we must first recount relevant

portions of Hornick‘s criminal history, and we then turn to the merits of the challenge.

                                             A

       Hornick‘s criminal record began years before the crimes at issue in this case. On

March 18, 1998, he pleaded guilty to conspiring to transport stolen property across state

lines in the United States District Court for the Eastern District of Pennsylvania. District

Judge William Yohn sentenced him to 27 months in prison, followed by three years of

supervised release, and ordered him to pay $76,500 in restitution. After completing his

prison sentence, Hornick absconded from supervised release. This prompted the District

Court to issue a warrant directing Hornick to appear before the court for a hearing on

revocation of supervised release. Hornick subsequently was arrested by New Jersey

officials on a state parole violation and was sentenced to 270 days in prison.

       Hornick escaped from state prison on August 6, 2001 and remained at large until

Delaware state police arrested him in July 2007. Delaware authorities charged Hornick

with various drug, burglary, and false identification crimes. He attempted to escape,

unsuccessfully, in December 2007. In February 2008, he pleaded guilty to forgery,

receiving stolen property, possession of burglar‘s tools, and attempted escape. In June

2008, he pleaded guilty in Delaware court to a separate burglary charge. He had

completed his various terms of imprisonment for the state crimes when, in August 2008,

he appeared before Judge Yohn in the United States District Court for a hearing on

revocation of supervised release. Hornick stipulated to violating his supervised release



                                             4
(on the 1998 conviction) and Judge Yohn sentenced him to two years in federal prison,

followed by one year of supervised release.

       Nine months later, the Court of Common Pleas for Bucks County, Pennsylvania

issued two writs of habeas corpus ad prosequendum directing federal custodians to

release Hornick temporarily for trial on pending burglary charges. Federal officials

agreed and transported Hornick to Bucks County for arraignment and trial. He was in

state custody on June 11, 2009 when the federal grand jury returned the superseding

indictment against him in this case.

       District Judge Harvey Bartle, III, presiding over the superseding indictment,

issued a writ of habeas corpus ad prosequendum on June 16, 2009 to secure Hornick‘s

return to federal custody. Trial on the Bucks County burglary charges had not yet begun.

In compliance with the writ, Pennsylvania officials released Hornick back to federal

custody, and Hornick made an initial appearance on June 26, 2009. He pleaded not guilty

and agreed to remain in pretrial detention. In connection with his pretrial detention

stipulation, the Magistrate Judge asked, ―[I]t‘s my understanding that you‘re agreeing to

detention in this case, correct?‖ Appendix (―App.‖) 165. Hornick answered, ―Yes . . .

contingent upon being returned to Bucks County . . . to state custody.‖ Id. The

Magistrate Judge then confirmed that Hornick had signed ―the waiver‖ and stated, ―I will

order that you be detained pending the disposition of this case in the District Court. I

understand that you‘ve signed the waiver and we expect you to go back to the County

facility.‖ Id. at 165-66.



                                              5
       The spoken-of ―waiver‖ referred to a waiver form titled ―Waiver of Detainers

Act.‖ In it, Hornick affirmed that he had been ―advised of [his] rights under the Interstate

Agreement on Detainers Act‖ and that he ―waive[d his] right to remain in temporary

federal custody during the pendency of the criminal prosecution . . . and request[ed] that

the United States Marshal return [him] to the jurisdiction with original custody.‖ Hornick

Waiver of June 26, 2009.

       When federal officials did not, in fact, return Hornick to Pennsylvania custody, he

moved to dismiss the charges. He argued that the IAD required the Government to

comply with his request to return to state custody. The District Court denied the motion,

reasoning that the IAD did not protect Hornick because ―[t]he Act . . . does not apply to

pretrial detainees‖ and Hornick had not ―produced any evidence that he was serving a

sentence in state court at the time he was transferred to federal custody.‖ App. 26.

                                             B

       The Interstate Agreement on Detainers is an interstate compact entered into by 48

States (among them, Pennsylvania), the federal Government, and the District of

Columbia. 18 U.S.C. App. 2, § 2; 42 Pa. Cons. Stat. § 9101. It creates uniform

procedures for resolving one State‘s pending charges against an individual imprisoned by

another State. Alabama v. Bozeman, 533 U.S. 146, 148 (2001); New York v. Hill, 528

U.S. 110, 111 (2000). Article III extends to prisoners against whom a detainer is lodged

the right to demand final disposition on the pending charges within 180 days of release to

the charging jurisdiction unless good cause exists for a continuance. 18 U.S.C. App. 2, §



                                             6
2, Art. III(a).2 Article IV gives ―the jurisdiction in which an untried indictment,

information, or complaint is pending‖ the right ―to have a prisoner against whom‖ it ―has

lodged a detainer . . . made available‖ for trial. Id. Art. IV(a). If it secures custody of the

prisoner, the State that lodged the detainer (the ―receiving state‖) must bring the prisoner

to trial within 120 days. Id. Art. IV(c). An ―anti-shuttling provision‖ further requires the

receiving state to retain custody of the prisoner until disposition of the charges. Id. Art.

IV(e). Absent a waiver, transfer of the prisoner back to the sending state results in

dismissal, with prejudice, of the charges pending in the receiving state. Id.; see

Bozeman, 533 U.S. at 156 (holding that the IAD commands dismissal of charges even for

a one-day transgression of the anti-shuttling provision).

       Hornick began as a federal prisoner serving time for violating his supervised

release in a federal sentence. That is, his ―original place of imprisonment‖ was federal

prison. 18 U.S.C. App. 2, § 2, Art. IV(e). Pennsylvania assumed custody of Hornick and

sought to bring him to trial pursuant to a writ of habeas corpus ad prosequendum. But,

having never proceeded to trial and been found guilty on the Bucks County charges,

Hornick never was a Pennsylvania ―prisoner.‖ Id. Art IV(a). When the federal

2
  A detainer is ―a legal order that requires a State in which an individual is currently
imprisoned to hold that individual when he has finished serving his sentence so that he
may be tried by a different State for a different crime.‖ Bozeman, 533 U.S. at 148. It is a
form of legal process distinct from a writ of habeas corpus ad prosequendum. United
States v. Mauro, 436 U.S. 340, 358 (1978). A detainer ―puts the official of the institution
in which the prisoner is incarcerated on notice that the prisoner is wanted in another
jurisdiction for trial upon his release from prison. Further action must be taken by the
receiving State in order to obtain the prisoner.‖ Id. By contrast, a writ of habeas corpus
ad prosequendum directs prison officials to make the prisoner available immediately for
trial. Id. at 357-58. A court that issues a writ of habeas corpus ad prosequendum need
not have lodged a detainer in order to secure the presence of the prisoner.
                                               7
Government regained custody of him, it did so pursuant to its own writ of habeas corpus

ad prosequendum. It never lodged a detainer with Bucks County, nor did it need to, in

order to reacquire custody of its own prisoner. United States v. Jones, 938 F.2d 447, 449

(3d Cir. 1991). Because the Government did not file a detainer, the IAD was never

triggered and its protections never covered Hornick.

       Hornick‘s arguments to the contrary misconstrue the reach of the IAD and muddle

the distinction between detainers and writs of habeas corpus ad prosequendum. He

contends that his waiver of rights under the IAD transformed the Government‘s writ of

habeas corpus ad prosequendum into a detainer. It appears that the Magistrate Judge‘s

statements to Hornick suggested, incorrectly, that he had the power to order Hornick‘s

return to state custody. But neither the waiver nor the Magistrate‘s comments can

convert the Government‘s writ into a detainer. The Supreme Court has emphasized that

writs of habeas corpus ad prosequendum and detainers are distinct forms of legal process,

with different purposes, histories, and effects on prisoners. United States v. Mauro, 436

U.S. 340, 357-61 (1978); see also Jones, 938 F.2d at 449. Having failed to introduce

evidence of a federal detainer, Hornick has no IAD claim against the United States.3

       Hornick next contends that his transfer from federal prison to Bucks County

authorities triggered the IAD. If this is so, Hornick has a claim against Pennsylvania, not


3
 This result aligns with the IAD‘s purpose to combat the detrimental effects of lingering
detainers, such as interruption of prisoner rehabilitation and sentencing distortions.
Mauro, 436 U.S. at 359-60. When the United States secures custody of a detainee by
means of a writ of habeas corpus ad prosequendum, ―the problems that the Agreement
sought to eliminate do not arise.‖ Id. at 361.

                                             8
the United States. He also argues that he was a sentenced state prisoner when he was

transported from Bucks County back to the United States. He is incorrect; at that point in

time, he was serving a federal sentence, but was a pretrial detainee with respect to

Pennsylvania. The District Court properly denied Hornick‘s motion to dismiss, for the

federal Government did not transgress the IAD.

                                            III

       Hornick‘s second claim is that the District Court abused its discretion when it

denied his motion for a mistrial after a witness alluded to his appearance on the television

show America’s Most Wanted. ―We review the denial of a motion for a mistrial based on

a witness‘s allegedly prejudicial comments for an abuse of discretion.‖ United States v.

Lore, 430 F.3d 190, 207 (3d Cir. 2005).

       On the fourth day of the trial, the Government called Malcom, the coconspirator

who purchased goods stolen by Hornick and the other conspirators, to testify. During

cross-examination, defense counsel asked Malcom, ―Did you tell the Government that

you never thought of Hornick as a bad guy and if you knew what Malcom — if you knew

what Hornick had been associated — been involved in, you never would have associated

with him?‖ App. 1105-06. Malcom responded, ―I probably said that Scott was, as far as

I knew, was a good guy, always felt that he was okay, but when I found out that he was

Americas most wanted,‖ at which point defense counsel interjected. Id. The jurors‘

reactions to Malcom‘s slip prompted defense counsel to move for a mistrial. The District

Court denied the motion, but gave the jury the following cautionary instruction: ―Vallin

Malcom was asked at one point about his opinion of the Defendant. In this context, he

                                             9
characterized the Defendants as one of America‘s Most Wanted. His comment is

total[ly] irrelevant, is not evidence, and must not be considered by you in deciding the

case. You‘re absolutely bound to follow this instruction.‖ App. 1359-60. Hornick

contends that Malcom‘s outburst was unresponsive to defense counsel‘s question and

insurmountably prejudicial. The Government argues that the testimony was not

prejudicial enough to warrant a mistrial.

       Three factors guide our review of a motion for a mistrial based on prejudicial

comments. United States v. Riley, 621 F.3d 312, 336 (3d Cir. 2010). We examine ―(1)

whether [the witness‘s] remarks were pronounced and persistent, creating a likelihood

they would mislead and prejudice the jury; (2) the strength of the other evidence; and (3)

curative action taken by the district court.‖ Id. (quoting Lore, 430 F.3d at 207). As

Malcom made only one passing allusion to America’s Most Wanted, his testimony was

hardly pronounced or persistent. Overwhelming evidence of Hornick‘s guilt supported

the verdict, dampening the prejudicial impact of Malcom‘s comment. And the District

Court took curative action by instructing the jury to disregard the comment. The court

did not abuse its discretion in concluding that Malcom‘s remark, though inadmissible

under Federal Rule of Evidence 404 and prejudicial, was not so prejudicial as to impugn

the jury‘s verdict and necessitate retrial. See United States v. Baker, 432 F.3d 1189,

1219-20, 1225 (11th Cir. 2005) (holding that although testimony that the defendant

appeared on America’s Most Wanted should have been excluded, its admission was

harmless error in light of the ―avalanche‖ of inculpatory evidence); Ford v. Curtis, 277

F.3d 806, 811 (6th Cir. 2002) (same).

                                            10
                                             IV

       Hornick next contends that the District Court erred in denying his pretrial motion

to dismiss count 1 of the indictment as duplicitous. An indictment tainted by duplicity

improperly joins distinct and separate offenses in a single count. United States v. Starks,

515 F.2d 112, 116 (3d Cir. 1975). We exercise plenary review over the legal question

whether an indictment is duplicitous. United States v. Root, 585 F.3d 145, 150 (3d Cir.

2009). ―‗[I]n considering a defense motion to dismiss an indictment, the district court

[must] accept[] as true the factual allegations set forth in the indictment.‘‖ United States

v. Bergrin, 650 F.3d 257, 265 (3d Cir. 2011) (quoting United States v. Besmajian, 910

F.2d 1153, 1154 (3d Cir. 1990)).

       Count 1 charged Hornick with a single conspiracy to commit interstate

transportation of stolen property in violation of 18 U.S.C. § 371. Named as

coconspirators were Malcom, Ingardi, the Todisco brothers, and ―others.‖ The

conspiracy allegedly operated from August 2001 to July 2007. Overt acts in furtherance

of the conspiracy included 30 burglaries of retail stores in ten states. The indictment

charged that Hornick and two individuals, ―R.M. and R.M.M.‖ (the Moran brothers),

burglarized stores and transported the stolen goods across state lines until October 2002.

Malcom allegedly purchased the stolen goods for resale. After authorities arrested the

Moran brothers in August 2002, Hornick replaced them with Ingardi and the Todisco

brothers. The indictment charged that Hornick, Ingardi, and the Todisco brothers

likewise burglarized retail establishments and delivered stolen goods to Malcom.



                                             11
       Before trial, Hornick moved to dismiss count 1 on the basis that the charge was

duplicitous. He contended that the indictment in fact charged two separate conspiracies:

one between Hornick, Malcom, and the Moran brothers from August 2001 to October

2002, and a second between Hornick, Malcom, Ingardi, and the Todisco brothers from

November 2002 to July 2007. The District Court denied the motion, concluding that the

indictment charged one overarching conspiracy with a single object.

       We evaluate three factors to determine ―whether a group of individuals engaged in

a single conspiracy or multiple conspiracies: . . . (1) ‗whether there was a common goal

among the conspirators‘; (2) ‗whether the agreement contemplated bringing to pass a

continuous result that will not continue without the continuous cooperation of the

conspirators‘; and (3) ‗the extent to which the participants overlap in the various

dealings.‘‖ United States v. Kemp, 500 F.3d 257, 287 (3d Cir. 2007) (quoting United

States v. Kelly, 892 F.2d 255, 259 (3d Cir. 1989)).

       The indictment alleged that Hornick and his coconspirators shared the common

objective of burglarizing retail stores and transporting the pilfered merchandise across

state lines for resale on the black market. Both before and after October 2002, the

indictment alleged, Hornick and his conspirators achieved the same result — burglary

and resale of stolen goods — by using substantially the same method. In particular, both

phases of the conspiracy relied on stolen vehicles, burglar‘s tools, and forcible entries.

Finally, the indictment charged that the leader of the conspiracy (Hornick) and the fence

(Malcom) remained constant, despite the substitution of auxiliary coconspirators. As all

three factors indicate that count 1 charged the operation of a single conspiracy, the

                                             12
District Court correctly concluded that the indictment was not duplicitous. See Kelly,

892 F.2d at 259 (―A single conspiracy is not transformed into a series of unrelated,

multiple conspiracies merely through a change in its membership.‖).4

                                              V

       Hornick‘s final claim is that the District Court vitiated his theory of the case by

severing from the jury charge on count 1 evidence of burglaries he committed with the

Moran brothers before October 2002. This modification, he argues, either amounted to a

constructive amendment of the indictment or signified a variance between the single

conspiracy charged and the evidence adduced at trial. In the alternative, he argues that

the District Court abused its discretion by retroactively admitting the evidence of his

dealings with the Moran brothers.

       On February 18, 2010, after the parties rested, the District Court held a charge

conference with the attorneys.5 Defense counsel moved for a judgment of acquittal on



4
  Hornick also argues that count 1 of the indictment does not comply with Fed. R. Crim.
P. 7(c), which requires ―a plain, concise and definite written statement of the essential
facts constituting the offense charged.‖ Count 1 is deficient, in Hornick‘s view, because
it lists burglaries of 30 retail establishments as overt acts in furtherance of the conspiracy,
but omits additional burglaries on which the Government relied to obtain a sentencing
enhancement. Consequently, he reasons, it affords insufficient protection against future
prosecution for the same crime. The argument is meritless. Spanning 11 pages, count 1
apprises Hornick of the elements of the offense and sets forth in great detail the factual
predicate for the conspiracy charge. It demarcates the conspiracy temporally, providing
Hornick with a clear basis on which to raise a double jeopardy defense in the event he is
prosecuted again for the conspiracy. See United States v. Rankin, 870 F.2d 109, 112 (3d
Cir. 1989) (setting forth test for judging the sufficiency of an indictment).
5
  No transcription or recording of the conference was prepared. The parties submitted,
pursuant to Federal Rule of Appellate Procedure 10, a statement of proceedings
describing the substance of the conference. Supplemental Appendix (―Supp. App.‖) 187-
                                              13
count 1. Reviving the theory of his motion to dismiss, he argued that the evidence proved

the existence of multiple conspiracies. And, he continued, the prejudicial variance

between the indictment and the proof presented at trial justified directed acquittal on the

charge. In the alternative, defense counsel requested a jury instruction on his multiple

conspiracy theory. He planned to argue to the jury in summation that the evidence

demonstrated the operation of two conspiracies, not a single conspiracy, and that acquittal

was the proper remedy for the variance between the indictment and trial evidence.6

       The District Court denied the motion for acquittal but ―questioned the wisdom of

presenting the jury with [the] unnecessary and potentially complex issue‖ of single versus

multiple conspiracies. Supp. App. 189. Instead, the court proposed that the conspiracy

charge exclude Hornick‘s dealings with the Moran brothers and begin at November 2002

rather than August 2001. That is, the Government could prove the conspiracy charge

only on the basis of evidence of Hornick‘s interactions with Ingardi and the Todisco

90. We rely on the statement in recounting the court‘s decisions and the parties‘
positions and objections.
6
 On February 17, 2010, the day before the charge conference, the District Court
distributed a proposed jury charge that included a multiple conspiracy instruction.
Paragraph 83, titled ―Conspiracy – Single or Multiple,‖ provided

       [T]he indictment charges that Scott Hornick and the other alleged co-conspirators
       were all members of one single conspiracy to commit the offense of interstate
       transportation of stolen property. Scott Hornick has argued that there were really
       two or more separate conspiracies: one between Scott Hornick, Sasha Janice
       Ingardi, Vallin Malcom, Jerry Todisco, and Anthony Todisco, to commit interstate
       transportation of stolen property, and another between Scott Hornick, Renee
       Maron and Orlando Maron [sic] to burglarize businesses. Whether a single
       conspiracy or multiple conspiracies exist is a question of fact that you must decide.

App. 133 ¶ 83. The District Court excised this language in the final jury charge.

brothers. Evidence admitted about Hornick‘s activities with the Moran brothers from

August 2001 to October 2002 would not supply proof of a conspiracy, but would be

admitted as proof of state of mind, knowledge, intent, motive, opportunity, preparation,

plan, or absence of mistake under Federal Rule of Evidence 404(b).

       The Government acceded to the proposal. Defense counsel wished to confer with

Hornick before deciding whether to object to the modified charge, but noted that

constricting the charge in this fashion would obviate his request for an instruction on

multiple conspiracies. The following day, the District Court charged the jury according

to its revised instruction. App. 1342-48. ―Count 1 of the indictment,‖ the court

instructed, ―charges that in or about November 2002 and continuing through on or about

July 27th, 2007, . . . the Defendant agreed or conspired . . . to commit . . . interstate

transportation of stolen property.‖ Id. at 1342. After the jury retired, defense counsel

objected to the revised conspiracy charge. He also objected that, if the Moran brothers

evidence was no longer proof of the conspiracy, that evidence should have been excluded

under Federal Rule of Evidence 404(b). The District Court overruled the objections.

                                               A

       Hornick argues that by cropping the time frame of the conspiracy, the District

Court constructively amended count 1 of the indictment in violation of the Grand Jury

Clause of the Fifth Amendment.7 ―An indictment is constructively amended when, in the


7
 The Grand Jury Clause provides, ―No person shall be held to answer for a capital, or
otherwise infamous crime, unless on a presentation or indictment of a Grand Jury.‖ U.S.
Const. art. V. The prohibition against constructive amendments derives from the clause.
United States v. Miller, 471 U.S. 130, 136-37 (1985).

absence of a formal amendment, the evidence and jury instructions at trial modify

essential terms of the charged offense in such a way that there is a substantial likelihood

that the jury may have convicted the defendant for an offense differing from the offense

the indictment returned by the grand jury actually charged.‖ United States v. Daraio, 445

F.3d 253, 259-60 (3d Cir. 2006) (citing United States v. Miller, 471 U.S. 130, 140

(1985)). ―We exercise plenary review in determining whether there was a constructive

amendment of the indictment.‖ Id. at 259.

       In reviewing a claim of constructive amendment, the ―key inquiry is whether the

defendant was convicted of the same conduct for which he was indicted.‖ Id. at 260. An

indictment is constructively amended when trial evidence and jury instructions broaden

the possible bases for conviction beyond those charged in the indictment. Miller, 471

U.S. at 138-39; United States v. Vosburgh, 602 F.3d 512, 532 (3d Cir. 2010). When trial

evidence and jury instructions narrow the scope of evidence that may be used to prove an

offense charged in the indictment, there is no constructive amendment. Miller, 471 U.S.

at 138-39; United States v. Castro, 776 F.2d 1118, 1123 (3d Cir. 1985).

       Count 1 of the indictment charged Hornick with conspiracy to commit interstate

transportation of stolen property in violation of 18 U.S.C. § 371. It is undisputed that

Hornick was tried on that offense and the District Court thoroughly and accurately

charged the jury on the elements of offense. Nor did the jury hear evidence that fell

beyond the scope of the conspiracy charge.

       Hornick argues that the District Court constructively amended the charge by

narrowing the time span of the conspiracy in the jury instructions. The argument is

                                             16
foreclosed, however, by United States v. Miller, in which the Supreme Court held that ―a

conviction for a criminal plan narrower than, but fully included within, the plan set forth

in the indictment‖ is not a constructive amendment. 471 U.S. at 138; see also Salinger v.

United States, 272 U.S. 542, 548-49 (1926). The District Court eliminated evidence that

could support a conspiracy conviction; it did not add a new offense or new evidence to

the charge. This case falls squarely within Miller‘s holding that, ―[a]s long as the crime

and the elements of the offense that sustain the conviction are fully and clearly set out in

the indictment, the right to a grand jury is not normally violated by the fact that the

indictment alleges . . . other means of committing the same crime.‖ Miller, 471 U.S. at

136.

                                              1

       Hornick next argues that the evidence proffered at trial impermissibly and

prejudicially varied from the single conspiracy charged in the indictment. ―Where a

single conspiracy is alleged in the indictment, there is a variance if the evidence at trial

proves only the existence of multiple conspiracies.‖ Kelly, 892 F.2d at 258. Animated

by notice and fairness concerns, the variance rule stems from the Due Process Clause of

the Fifth Amendment and, unlike the constructive amendment rule, contains a prejudice

requirement. Kotteakos v. United States, 328 U.S. 750, 757-58 (1946); Daraio, 445 F.3d

at 261-62. To establish reversible error based on a variance, a defendant must show

―first, that there was such a variance and, second, that the variance prejudiced one of his

substantial rights.‖ United States v. Quintero, 38 F.3d 1317, 1337 (3d Cir. 1994).

                                              17
       To determine whether there was a variance, we return to the three factors set forth

in United States v. Kelly, set forth in section IV. Whereas before our review trained only

on the indictment, we now review the entire trial record to determine if the conspirators

sought a common end, contemplated a continuous result, and overlapped in various

dealings. Kelly, 892 F.2d at 259. In considering these factors, we are mindful that ―a

finding of a master conspiracy with sub-schemes does not constitute a finding of

multiple, unrelated conspiracies.‖ United States v. Smith, 789 F.2d 196, 200 (3d Cir.

1986). ―We exercise plenary review over ‗whether there was sufficient evidence from

which the jury could have concluded that the government proved the single conspiracy

alleged in the indictment.‘‖ United States v. Lee, 359 F.3d 194, 207 (3d Cir. 2004)

(quoting Kelly, 892 F.2d at 258).

       While our scope of review is broader, our conclusion on the multiple conspiracy

question remains unchanged. Hornick, testimony revealed, led one unified conspiracy

that existed to burglarize retail establishments in different states and transport the stolen

goods to Pennsylvania for resale on the black market. All coconspirators — the Moran

brothers, the Todisco brothers, Ingardi, and Malcom — shared this common goal. The

subtraction of the Moran brothers and addition of the Todisco brothers and Ingardi did

not change the objective; rather, Hornick slotted his new collaborators into a well-oiled

scheme. See Kelly, 892 F.2d at 259 (―Although the various personnel changed during the

[conspiracy], the central purpose was constant and pervasive.‖).

       Nor did the nature of the scheme and the result change in November 2002.

Precision and constancy characterized Hornick‘s burglary method in both phases of the

                                              18
conspiracy. Business targets were high-end camera or electronics stores and occasionally

included pharmacies, perfume stores, and guitar stores. App. 205-06. The burglars made

entry into stores through a rear or side entrance, most often with a crowbar, in the hours

between midnight and sunrise. Id. at 206, 510, 519-20, 639-40, 932. They wore dark

clothing, facemasks, and latex gloves to guard against telltale fingerprints. Id. at 206-07,

464, 506-07. Per Hornick‘s ―60-second rule,‖ the conspirators remained in stores no

longer than 60 seconds, sweeping as many items into heavy-duty trash bags as time

would allow. Id. at 506-07. Hornick alone brought the spoils to Malcom and received

from him 30 to 50 percent their retail value in cash. Id. at 623, 765, 931, 1066, 1072.

Burglaries with the Moran brothers and with the Todisco brothers and Ingardi shared

these common features. Id. at 464, 506-07, 639-40, 746-48, 752-53, 757-58, 931-32.

       The principal players in the conspiracy remained unchanged from August 2001 to

July 2007. Hornick was ―definitely the brains of the outfit,‖ the unquestioned leader of

the group and manipulator of his colleagues. Id. at 270-71, 688, 701. He lured Ingardi

and the Todisco brothers into participation, instructed them on how to conduct burglaries,

and chose target stores. During burglaries, he was the first one in and the last one out.

Id. at 538. No one exited until Hornick announced that 60 seconds had elapsed. Id. at

759. He chastised his collaborators when they grabbed merchandise that would not yield

a high return. Id. at 531, 601. Malcom, the other indispensable cog in the machine, was

the fence in both phases of the conspiracy, paying Hornick for the stolen goods and then

reselling those items to flea market vendors. The other conspirators enabled Hornick and

Malcom to make more money; they were not essential participants. See United States v.

                                             19
Boyd, 595 F.2d 120, 123 (3d Cir. 1978) (―[T]he government, without committing a

variance, . . . may establish the existence of a continuing core conspiracy which attracts

different members at different times and which involves different sub-groups committing

acts in furtherance of the overall plan.‖).8

         The evidence showed that both phases of the conspiracy not only were related, but

also were indistinguishable aside from the membership change. From 2001 to 2007, the

scheme had one goal, one method, and one outcome. The indictment alleged a single

conspiracy, and the proof presented at trial showed the continuous operation of one

overarching plan. We therefore conclude that each component of the three-part test

supports the finding of a single conspiracy, and we reject Hornick‘s argument that there

was an impermissible variance between the indictment and evidence proved at trial.9

                                               2

         Though he does not press the argument explicitly, lurking in Hornick‘s appeal is

an objection to the District Court‘s refusal to charge the jury on multiple conspiracies.

Hornick insists that the District Court‘s compartmentalization of the Moran brothers

evidence signifies that the ―trial judge believed, after hearing the evidence, that the

Moran brothers conduct with [Hornick] constituted a separate conspiracy.‖ Hornick Br.



8
 Hornick offers no argument as to how the evidence proved multiple conspiracies. His
sole objection is that he lacked notice of the charges lodged against him. Hornick Br. 54.
He is mistaken. The indictment clearly charges a single conspiracy and delimits the
conspiracy temporally.
9
    Because we find no variance, we need not address whether Hornick was prejudiced.

                                               20
51. Why else, he intimates, would the court take the question from the jury? The

argument has superficial appeal, but closer analysis shows that Hornick has it backwards.

       The District Court‘s denial of Hornick‘s motion for judgment for acquittal

signifies its determination that a reasonable jury could find a single, ongoing conspiracy.

Having rejected the theory that the evidence proved multiple conspiracies as a matter of

law, the District Court had two options. It could charge the jury on multiple conspiracies

or it could conclude that no reasonable jury could discern the operation of multiple

conspiracies. Which course to follow, of course, depends on the evidence. We have

explained that, as a general matter, ―[t]he issue of whether a single conspiracy or multiple

conspiracies exist is a fact question to be decided by a jury.‖ United States v. Perez, 280

F.3d 318, 346 (3d Cir. 2002) (citing United States v. Curran, 20 F.3d 560, 572 (3d Cir.

1994)). However, ―a district court can properly refuse a defendant‘s request for a jury

instruction on single versus multiple conspiracies if there is insufficient evidence to

support such an instruction.‖ United States v. Greenidge, 495 F.3d 85, 93 (3d Cir. 2007)

(citing United States v. Barr, 963 F.2d 641, 650 (3d Cir. 1992)).

       The question, then, is whether there was insufficient evidence to support a

multiple conspiracy instruction. As discussed, the evidence did not reveal the operation

of multiple conspiracies. And because the evidence ―did not demonstrate the existence of

‗separate, independent networks,‘ but rather, as the indictment charged, a single

conspiracy,‖ the District Court‘s rejection of Hornick‘s request for a multiple conspiracy

instruction was not improper. Greenidge, 495 F.3d at 95 (quoting Barr, 963 F.2d at 650).



                                             21
       Underlying the District Court‘s rejection of the multiple conspiracy instruction

was the concern that the jury not be confused by the ―unnecessary and potentially

complex issue‖ of single versus multiple conspiracies. Supp. App. 189. In United States

v. Barr, we encountered the same rationale for a District Court‘s rejection of a multiple

conspiracy instruction. 963 F.2d at 650. We found this reasoning sound in view of the

dearth of evidence of separate independent networks. Id. So, too, it is here.

                                             C

       Hornick‘s final claim is that even if the exclusion of the Moran brothers evidence

from the proof of the conspiracy was not a constructive amendment and did not signify a

variance, it was error to admit the evidence retroactively under Fed. R. Evid. 404(b).10

After the District Court concluded that a multiple conspiracy charge was unnecessary and

confusing, it instructed the jury that the Moran brothers evidence was not proof of the

conspiracy charged in count 1. However, the jury could consider the evidence

       for the purpose of deciding whether the Defendant had the state of mind,
       knowledge, or intent necessary to commit the crime charged in the
       indictment, had a motive or opportunity to commit the acts charged in the
       indictment, was preparing or planning to commit the acts charged in the
       indictment, acted with a method of operation as evidenced by unique
       pattern of committing burglaries, or did not commit the acts for which the
       Defendant is on trial by accident or mistake.


10
  Federal Rule of Evidence 404(b) provides, ―Evidence of a crime, wrong, or other act is
not admissible to prove a person‘s character in order to show that on a particular occasion
the person acted in accordance with the character.‖ Fed. R. Evid. 404(b)(1). However,
the evidence ―may be admissible for another purpose, such as proving motive,
opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of
accident.‖ Id. 404(b)(2). Upon the defendant‘s request, the prosecutor must ―provide
reasonable notice of the general nature of any such evidence that the prosecutor intends to
offer at trial.‖ Id. 404(b)(2)(A).
                                            22
App. 1347-48. The court warned, ―Do not consider this evidence for any other purpose. .

. . [Y]ou may not use this evidence to conclude that . . . because a Defendant may have

committed other acts he must also have committed the acts charged in the indictment.‖

Id. We review de novo the question whether the Moran brothers evidence falls within the

scope of Rule 404(b). United States v. Green, 617 F.3d 233, 239 (3d Cir. 2010).

       ―To be admissible under Rule 404(b), evidence of uncharged crimes or wrongs

must (1) have a proper evidentiary purpose; (2) be relevant; (3) satisfy Rule 403; and (4)

be accompanied by a limiting instruction (where requested) about the purpose for which

the jury may consider it.‖ Id. at 249. There is no dispute that the evidence was relevant

and was accompanied by a limiting instruction. Instead, Hornick argues that the evidence

had no proper evidentiary purpose and did not satisfy Rule 403.

       We agree with the Government that the evidence concerning Hornick‘s dealings

with the Moran brothers had a proper evidentiary purpose. ―A proper purpose is one that

is ‗probative of a material issue other than character.‘‖ Id. at 250 (quoting Huddleston v.

United States, 485 U.S. 681, 686 (1988)). The evidence of Hornick‘s October 2002

arrest and confession was proof of motive, for Hornick explained to officers that he

committed burglaries with the Moran brothers ―for a living.‖ App. 232. The evidence

concerning the Circuit City burglary that preceded Hornick‘s October 2002 arrest was

proof of a distinctive method of operation. Detective Sergeant Matthew Dox, an officer

with the Wayne, New Jersey Police, testified that officers recovered, among other things,

three crowbars, latex gloves, plastic bags, and a dust mask from the scene of the crime.

Id. at 464. These items were hallmarks of Hornick‘s burglaries and helped establish the

                                            23
distinctiveness of the plan underlying the conspiracy and subsequent burglaries. And

Malcom‘s testimony about his interactions with Hornick both before and after October

2002 helped to establish Hornick‘s intent to join the conspiracy and opportunity to

participate in the conspiracy.

         We find no error in the District Court‘s calculus under Federal Rule of Evidence

403. The Rule empowers a trial judge to exclude relevant evidence if ―its probative value

is substantially outweighed by the danger of unfair prejudice.‖ Fed. R. Evid. 403. ―We

review for abuse of discretion, which means we must uphold the District Court unless its

ruling was arbitrary or irrational.‖ Green, 617 F.3d at 251-52 (quotation marks omitted).

The District Court did not abuse its discretion in permitting the jury to consider the

evidence for the purposes stated in the jury instruction. While there was some risk that

the evidence would be unfairly prejudicial, the evidence also carried significant probative

value.

                                              VI

         For the foregoing reasons, we will affirm the judgment of the District Court.
