COMMONWEALTH OF PENNSYLVANIA                  IN THE SUPERIOR COURT OF

          Appeal from the Judgment of Sentence of June 12, 2013
           In the Court of Common Pleas of Philadelphia County
            Criminal Division at No.: CP-51-CR-0002313-2012


BEFORE: PANELLA, J., LAZARUS, J., and WECHT, J.

OPINION BY WECHT, J.:                                  FILED JULY 16, 2015

      This appeal requires that we determine the precise scope of the

“collective knowledge doctrine” in Pennsylvania. We conclude that the trial

court’s application of the doctrine to the facts of Alwasi Yong (“Yong”)’s

arrest stretched the rule beyond its breaking point.    As a result, the trial

court erred in denying Yong’s pretrial motion to suppress physical evidence.

We reverse the trial court’s order denying that motion, and we remand for

proceedings consistent with this opinion.

      On September 21, 2011, Officer Joseph McCook of the Philadelphia

Police Department was conducting narcotics surveillance on the 3200 block

of North Fairhill Street in Philadelphia. On that day, Officer McCook used a

confidential informant (“CI”) to conduct a controlled narcotics purchase.

Officer McCook observed Yong standing in front of a residence located at
J-A02021-15



3202 Fairhill Street. The CI approached Yong, had a brief conversation with

him, and then handed him $120 in pre-recorded currency. Yong passed the

money to his codefendant, Samuel Vega, who then entered the residence

and later returned with twelve packets of marijuana. Vega then handed the

marijuana to the CI.

      On September 22, 2011, police conducted surveillance of the same

area, but did not observe Yong.       The CI purchased twenty-five packets of

marijuana, which were similar to the twelve packets that the CI previously

had purchased from Yong and Vega. However, the record does not disclose

who sold the marijuana to the CI on September 22, 2011.             See Notes of

Testimony Suppression (“N.T.S.”), 4/17/2013, at 16 (“[T]here was a

transaction. I’m not sure if it was with Vega or not.”).

      On   September    23,   2011,    the   police   continued   their   narcotics

surveillance in the same area. Officer McCook observed Yong and Vega in

front of 3202 Fairhill Street.   Linwood Fairbanks, an undercover narcotics

officer, approached Vega and handed him $40 in pre-recorded currency.

Vega then walked over to a nearby vacant lot, retrieved something from the

ground, and returned with eight packets of marijuana, which he gave to

Officer Fairbanks.

      Approximately ten minutes after this transaction, police executed a

search warrant on 3202 North Fairhill Street. When police entered the home

to execute the search warrant, Yong was standing in the first-floor living

room. Without being prompted to do so by any other officer, and without

                                       -2-
J-A02021-15



knowing that other officers had observed Yong’s prior drug activity, Officer

Gerald Gibson immediately arrested Yong.         Officer Gibson discovered a

loaded .38 revolver concealed under Yong’s waistband.

       As a result of these events, Officer McCook filed a criminal complaint

charging Yong with various drug and firearm offenses.      On September 7,

2012, Yong filed an omnibus pretrial motion seeking to suppress the physical

evidence obtained from the search of his person. Therein, Yong argued that

Officer Gibson had neither reasonable suspicion to perform a Terry1 frisk,

nor probable cause to arrest and search him.

       On April 17, 2013, the trial court held a hearing on Yong’s motion to

suppress. The Commonwealth’s sole witness, Officer McCook, testified that

he personally observed Yong accept money from the CI on September 21,

2011. Officer McCook further testified that Yong then handed the money to

Vega, who gave the CI twelve packets of marijuana.       Officer McCook also

testified that, throughout his eighteen-year career as a Philadelphia Police

Officer, he had observed “hundreds” of narcotics transactions where one

participant accepts the money and then hands it off to a co-conspirator.

N.T.S. at 12.

dangerous).

     Officer Gibson did not testify at the suppression hearing.      Officer

McCook testified that he observed Yong participate in what he believed to be

a narcotics transaction on September 21, 2011.       Officer McCook further

testified that Officer Gibson arrested and searched Yong on September 23,

2011 when police executed the search warrant on 3202 North Fairhill Street.

While Officer McCook averred that he was present when Officer Gibson

recovered the firearm from Yong’s waistband, he stated that Officer Gibson

arrested Yong “[j]ust as [he] was going inside.” Id. at 18. Officer McCook

explained that “there were six or seven, maybe eight” officers executing the

search warrant, and that he was “towards the rear” as they entered the

home. N.T.S. at 17. Officer McCook did not testify that he informed Officer

Gibson of Yong’s role in the narcotics transaction on September 21, 2011,

nor did Officer McCook testify that he instructed Officer Gibson to arrest

and/or search Yong.

     At the conclusion of the hearing, Yong argued that his arrest was

unsupported by probable cause because the Commonwealth failed to

establish that “anyone spoke to Officer Gibson and told him what they had

seen on the 21st.”    Id. at 19.   The trial court denied Yong’s motion to

suppress, reasoning that Officer Gibson possessed sufficient probable cause

to arrest Yong because Officer McCook’s knowledge could be imputed to all

of the officers who were executing the search warrant.

     On April 22, 2013, Yong proceeded to a jury trial. On April 24, 2013,

the jury found Yong guilty of carrying a firearm without a license and of

                                   -4-
J-A02021-15



conspiracy to commit possession with intent to deliver (“PWID”). 2 Because

Yong stipulated that he had a prior felony conviction that prohibited him

from owning a firearm, the trial court also found Yong guilty of persons not

to possess a firearm3 in a severed proceeding.

       By oral motion advanced during his sentencing hearing on June 12,

2013, Yong argued that the jury’s guilty verdict on the conspiracy to commit

PWID count was against the weight of the evidence. The trial court denied

Yong’s motion, and sentenced him to five to ten years’ imprisonment for

persons not to possess a firearm, with concurrent terms of three and one

half to seven years’ imprisonment for firearms not to be carried without a

license and five to ten years’ imprisonment for conspiracy to commit PWID.

       On July 8, 2013, Yong timely filed a notice of appeal.   On July 15,

2013, the trial court directed Yong to file a concise statement of errors

complained of on appeal pursuant to Pa.R.A.P. 1925(b).          Yong timely

complied.

       Yong presents two issues for our consideration:

       1. Did the trial court err in denying Yong’s pretrial motion to
          suppress the search of his person where the arresting officer
          had neither probable cause to arrest Yong nor reasonable
          suspicion to perform a [Terry] frisk where Yong was merely
          present during the execution of a search warrant?

J-A02021-15


      2. Was the evidence insufficient to support Yong’s conviction for
         criminal conspiracy where a veteran police officer wrote in his
         investigation report that Yong entered one house and then
         handed a clear bag to a confidential informant[,] but that
         same officer twice testified that it was [Vega] who went into a
         different house and handed the same small objects to the
         same confidential informant?

Brief for Yong at 7 (footnote omitted).

      Yong first contends that the trial court erred in denying his motion to

suppress the physical evidence obtained from his person. Our standard of

review in this context is well-settled:

      In addressing a challenge to a trial court’s denial of a
      suppression motion, we are limited to determining whether the
      factual findings are supported by the record and whether the
      legal conclusions drawn from those facts are correct. Since the
      Commonwealth prevailed in the suppression court, we may
      consider only the evidence of the Commonwealth and so much of
      the evidence for the defense as remains uncontradicted when
      read in the context of the record as a whole. Where the record
      supports the factual findings of the trial court, we are bound by
      those facts and may reverse only if the legal conclusions drawn
      therefrom are in error.

Commonwealth v. Brown, 64 A.3d 1101, 1104 (Pa. Super. 2013) (citation

omitted).   Our scope of review in suppression matters includes only the

suppression hearing record, and excludes any evidence elicited at trial. See

In re L.J., 79 A.3d 1073, 1085 (Pa. 2013).

      Probable cause to arrest is not mere suspicion or conjecture.        The

relevant inquiry is “whether the facts and circumstances which are within the

knowledge of the officer at the time of the arrest, and of which he has

reasonably trustworthy information, are sufficient to warrant a man of


                                      -6-
J-A02021-15



reasonable caution in the belief that the suspect has committed or is

committing a crime.”        Commonwealth v. Rodriguez, 585 A.2d 988, 990

(Pa. 1991).

       Yong does not dispute that Officer McCook’s knowledge that Yong

participated in a narcotics transaction two days earlier amounted to

sufficient probable cause to justify a warrantless arrest.    It was Officer

Gibson, not Officer McCook, who ultimately arrested Yong.        Yong argues

that the trial court erred in imputing Officer McCook’s knowledge to Officer

Gibson.4 See N.T.S. at 23 (“[T]he knowledge of one is imputed to all on the

scene that day, all the [officers] who are executing the search warrant.”).

       The Commonwealth maintains that Officer McCook’s knowledge of

Yong’s participation in the earlier drug transaction was imputed to Officer

Gibson under the “collective knowledge doctrine.” The Commonwealth cites

no Pennsylvania case law to support such an expansion of the rule. For the

reasons that follow, we conclude that such an interpretation would stretch

the doctrine well beyond its stated purpose.

       At Yong’s suppression hearing, the trial court also reasoned that the
police were “entitled” to search everyone inside of the residence because
they were executing a valid search warrant. N.T.S. at 22. This is incorrect.
We have held that, unless the police obtain an “all persons present” warrant,
mere presence during the execution of a search warrant, by itself, is
insufficient to justify a search of the person. In re J.V., 762 A.2d 376, 382
(Pa. Super. 2000).




                                           -7-
J-A02021-15



     The collective knowledge doctrine (sometimes called the “fellow-officer

rule”) was first articulated by then circuit-court judge Warren Burger in

Williams v. United States, 308 F.2d 326 (D.C. Cir. 1962).           There, an

appellant argued that his arrest was unconstitutional because the arresting

officer lacked “adequate first hand information” amounting to probable

cause.   The Court rejected this theory, finding that the arresting officer

acted based upon the knowledge of another officer within the department

who clearly had probable cause to arrest the appellant.

     [I]n a large metropolitan police establishment the collective
     knowledge of the organization as a whole can be imputed to an
     individual officer when he is requested or authorized by
     superiors or associates to make an arrest. The whole complex
     of swift modern communication in a large police department
     would be a futility if the authority of an individual officer was to
     be circumscribed by the scope of his first hand knowledge of
     facts concerning a crime or alleged crime.

     When the police department possesses information which would
     support an arrest without a warrant in the circumstances, the
     arresting officer, if acting under orders based on that
     information, need not personally or first hand know all the
     facts. The test, as we have said, is whether a prudent and
     cautious officer in those circumstances would have reasonable
     grounds—not proof or actual knowledge—to believe that a crime
     had been committed and that appellant was the offender.

Id. (emphasis added).

     In Whiteley v. Warden, 401 U.S. 560 (1971), the United States

Supreme Court echoed the D.C. Circuit’s reasoning. There, a county sheriff

received an uncorroborated tip stating that Whiteley and an accomplice had

burglarized two local businesses.     The sheriff then obtained an arrest


                                    -8-
J-A02021-15



warrant based upon an insufficient showing of probable cause.           See id. at

565 (“Th[e] complaint consists of nothing more than the [sheriff’s]

conclusion that the individuals named therein perpetrated the offense

described in the complaint.         The actual basis for [the sheriff’s] conclusion

was . . . omitted from the complaint.”). Following the issuance of the arrest

warrant, the sheriff distributed a statewide bulletin via police radio,

requesting that any officer who encountered the suspects arrest and

extradite them.5       After hearing the bulletin, a patrol officer in a nearby

county arrested the two men and discovered evidence of the burglaries in

Whiteley’s vehicle.

       The Whiteley Court held that: (1) the sheriff’s complaint was

insufficient to support the issuance of an arrest warrant; and (2) the

informer’s tip lacked sufficient indicia of reliability to provide the sheriff with

probable cause. Still, the state argued that the arresting officer reasonably

relied upon the police radio bulletin and, therefore, had sufficient probable

cause to arrest the suspect. The state urged that preventing “officers from

acting on the assumption that fellow officers who call upon them to make

an arrest have probable cause for believing the arrestees are [perpetrators]



____________________________________________

      Specifically, the bulletin contained the names and physical descriptions
of the two suspects, described the vehicle that they were believed to be
traveling in, and stated that an arrest warrant for the two men had been
issued. Whiteley, 401 U.S. at 564.



                                           -9-
J-A02021-15



of a crime would . . . unduly hamper law enforcement.”              Id. at 568

(emphasis added).

      Justice John Harlan, writing for the majority, rejected this logic.

      We do not, of course, question that the . . . police were entitled
      to act on the strength of the radio bulletin. Certainly police
      officers called upon to aid other officers in executing arrest
      warrants are entitled to assume that the officers requesting aid
      offered the magistrate the information requisite to support an
      independent judicial assessment of probable cause. Where,
      however, the contrary turns out to be true, an otherwise illegal
      arrest cannot be insulated from challenge by the decision of the
      instigating officer to rely on fellow officers to make the arrest.

Id.   This rule, which later became known as the “collective knowledge

doctrine,” was a matter of common sense.            Had the Court concluded

otherwise, the probable cause requirement could be easily circumvented;

any officer could simply instruct another officer to make an illegal arrest.

      In United States v. Hensley, 469 U.S. 221 (1985), the United States

Supreme Court again considered the constitutionality of an arrest based

upon a law enforcement bulletin.        Expounding the collective knowledge

doctrine’s rationale, the Court explained:

      Whiteley supports the proposition that, when evidence is
      uncovered during a search incident to an arrest in reliance
      merely on a flyer or bulletin, its admissibility turns on whether
      the officers who issued the flyer possessed probable cause to
      make the arrest. It does not turn on whether those relying on
      the flyer were themselves aware of the specific facts which led
      their colleagues to seek their assistance.       In an era when
      criminal suspects are increasingly mobile and increasingly likely
      to flee across jurisdictional boundaries, this rule is a matter of
      common sense: it minimizes the volume of information
      concerning suspects that must be transmitted to other


                                     - 10 -
J-A02021-15


       jurisdictions and enables police in one jurisdiction to act
       promptly in reliance on information from another jurisdiction.

Id. at 231.

       Read jointly, Whiteley and Hensley instruct that the collective

knowledge doctrine serves an agency function.                  When a police officer

instructs or requests another officer to make an arrest, the arresting officer

stands in the shoes of the instructing officer and shares in his or her

knowledge. In Commonwealth v. Kenney, 297 A.2d 794 (Pa. 1972), the

Pennsylvania Supreme Court adopted the rationale of Whiteley, and upheld

a warrantless arrest made by a detective who lacked probable cause, where

he acted at the direction of his superior who had specific knowledge of facts

and circumstances sufficient to constitute probable cause.               Pennsylvania

courts have since cited Whiteley and Hensley for the general proposition

that an arresting officer need not possess encyclopedic knowledge of the

underlying facts supporting probable cause.               Instead, he or she may rely

upon an instruction6 to arrest from another officer who possesses the

required knowledge.         See In re D.M., 727 A.2d 556, 558 (Pa. 1999);

Commonwealth           v.    Queen,       639      A.2d    443,   445   (Pa.   1994);

      There are no “magic words” that must pass between police officers to
invoke the collective knowledge doctrine. The requirement that there be an
actual communication between the fellow officers presents only a negligible
burden to law enforcement. An officer may issue a conclusory directive to
arrest a particular suspect. See generally 2 Wayne R. LaFave, Search and
Seizure § 3.5 (5th ed. 2012).



                                          - 11 -

Commonwealth           v.   Wagner,       406      A.2d   1026,    1030   (Pa.   1979);

Commonwealth v. Cotton, 740 A.2d 258, 262-63 (Pa. Super. 1999);

Commonwealth v. Fromal, 572 A.2d 711, 717 (Pa. Super. 1990).7

       Instantly, there is nothing in the suppression record to suggest that:

(1) Officer McCook ordered or directed Officer Gibson to arrest Yong; or (2)

Officer Gibson received information justifying Yong’s arrest; or (3) Officer

Gibson received information, which, coupled with facts that he personally

observed, provided probable cause to arrest Yong.                 This lack of evidence

compels the conclusion that Officer Gibson—acting of his own accord—made

a warrantless arrest.       The fact that, unbeknownst to Officer Gibson, his

colleague    Officer   McCook had observed Yong participate                 in a   drug

       We are aware of no cases in which the Pennsylvania Supreme Court
has departed from or expanded upon the rule announced in Whiteley. In
Commonwealth v. Gambit, a panel of this Court stated that a police
officer’s knowledge can be imputed to his fellow officer where there “is some
communication or connection” between them. 418 A.2d 554, 557 (Pa.
Super. 1980). This seems to suggest that the collective knowledge may
apply in the absence of a communication, so long as a particular officer is
“connected to” an arrest. But, read in context, the inclusion of the word
“connection” appears to be an imprecise statement of the law, and not an
explicit enlargement of the doctrine. Indeed, the Court in Gambit rejected
the Commonwealth’s argument that relevant information possessed by an
officer could be imputed to an arresting officer in the absence of an
instruction or directive to arrest. Moreover, in the thirty-five years since
Gambit was decided, it has never been cited for the proposition that
knowledge can be imputed between officers in the absence of a
communication between them.         Instead, our own Supreme Court has
explained that Whiteley simply allows an officer to make a warrantless
arrest “undertaken at the direction of his superior who had sufficient
knowledge of facts and circumstances to constitute probable cause to arrest
the defendant.” Commonwealth v. Queen, 639 A.2d 443, 446 (Pa. 1994).

transaction two days earlier cannot suffice to permit the Commonwealth to

leapfrog the Fourth Amendment.

      Citing decisions issued by various federal courts, the Commonwealth

encourages us to adopt a far more expansive rule.             A series of conflicting

interpretations of the collective knowledge doctrine have emerged over the

last several decades.      Some courts have conceptualized the collective

knowledge cases as falling into two distinct categories, vertical and

horizontal.      The   “vertical”   collective   knowledge       cases      present   a

straightforward application of Whiteley and Hensley (i.e., where one law

enforcement officer who possesses probable cause instructs a fellow officer

to act). As discussed supra, Pennsylvania courts have consistently applied

this version of the doctrine for several decades, with little controversy.

      By contrast, the “horizontal” collective knowledge cases arise when

individual law enforcement officers each possess pieces of the probable

cause puzzle, but no single police officer possesses information that amounts

to probable cause. United States v. Chavez, 534 F.3d 1338, 1345 (10th

Cir. 2008) (citing United States v. Shareef, 100 F.3d 1491, 1503-05 (10th

Cir. 1996)).     Under this approach, which has never been adopted in

Pennsylvania, courts evaluate probable cause by aggregating the knowledge

of two or more police officers who are working together on an investigation.

      The     Commonwealth     cites   several   of   these    horizontal    collective

knowledge cases for the general proposition that “the information available

to a close group of officers functioning as a team is assessed as a whole.”

                                       - 13 -
J-A02021-15



Brief for Commonwealth at 10. According to the Commonwealth, we must

consider the facts within Officer McCook’s knowledge in order to determine

whether Officer Gibson had probable cause to arrest Yong.

      The view that a broader, “horizontal,” collective knowledge doctrine

exists is far from unanimous.    Many courts have declined to enlarge the

scope of the doctrine, and will only impute knowledge among fellow officers

where there is evidence that the arresting officer acted at the direction of

another officer.   See United States v. Massenburg, 654 F.3d 480, 493

(4th Cir. 2011) (“[T]he collective-knowledge doctrine simply directs us to

substitute the knowledge of the instructing officer or officers for the

knowledge of the acting officer. . . .” (emphasis in original)); Haywood v.

United States, 584 A.2d 552, 557 (D.C. 1990) (“An arresting officer need

not have firsthand knowledge of the facts giving rise to probable cause

provided that he or she is acting at the suggestion of someone who does.”

(emphasis in original)); United States v. Woods, 544 F.2d 242 (6th Cir.

1976) (holding that supervising officer’s knowledge could not be imputed to

arresting officer where the evidence fails to demonstrate that the arrest was

based upon supervising officer’s order to arrest); State v. Cooley, 457 A.2d

352, 356 (Del. 1983) (citing Gambit, 418 A.2d 554); State v. Mickelson,

526 P.2d 583, 584 (Or. App. 1974) (“A police officer working in a team or in

a modern police organization is entitled reasonably to arrest or search on the

command or summary information of another officer.”).

J-A02021-15



       There does not appear to be a coherent rationale for enlarging the

scope of the doctrine beyond the situation where an officer with probable

cause directs a fellow officer to make an arrest.8   Extending the collective

knowledge doctrine to apply in the absence of a directive or instruction to

arrest issued by an officer who possesses probable cause serves none of the

legitimate law enforcement purposes behind the rule.      See Hensley, 469

U.S. at 231 (“In an era when criminal suspects are increasingly mobile and

increasingly likely to flee across jurisdictional boundaries, this rule is a

matter of common sense: it minimizes the volume of information concerning

suspects that must be transmitted to other jurisdictions and enables police in

one jurisdiction to act promptly in reliance on information from another

jurisdiction.”).    Many of the courts that have adopted the horizontal

approach to the collective knowledge doctrine have ignored the original aim

of the rule—to allow officers to rely upon succinct directives received from a

fellow officer.    Paradoxically, these courts have expanded the rule, which

was intended to encourage communication between police officers while

minimizing the volume of information that officers must transmit, by



____________________________________________

       Indeed, some courts have adopted the horizontal collective knowledge
approach while purporting to apply the collective knowledge doctrine in its
traditional form. See, e.g., United States v. Verdugo, 617 F.3d 565 (1st
Cir. 2010) (assessing “the collective knowledge of the agents working . . . on
[an] investigation.”).



                                          - 15 -

eliminating the requirement that officers actually communicate with one

another.

     The Supreme Court has endorsed the view “that effective law

enforcement cannot be conducted unless police officers can act on directions

and information transmitted by one officer to another and that officers, who

must often act swiftly, cannot be expected to cross-examine their fellow

officers about the foundation for the transmitted information.” Id. If there

is no ‘transmitted information,’ a different result obtains. Our law does not

permit a police officer to make a warrantless arrest and then later justify it

based upon his colleague’s knowledge.          To adopt the horizontal collective

knowledge approach would be to sever the doctrine from its constitutional

impetus.

     Moreover, an expansive interpretation of the collective knowledge

doctrine   does   not   comport   with   the    fundamental    requirement   that

warrantless arrests be supported by probable cause.         The benchmark of a

warrantless arrest is “whether the facts and circumstances which are within

the knowledge of the officer at the time of the arrest, and of which he has

reasonably trustworthy information, are sufficient to warrant a man of

reasonable caution in the belief that the suspect has committed or is

committing a crime.”     Commonwealth v. Rodriguez, 585 A.2d 988, 990

(Pa. 1991).   In the context of probable cause to conduct a warrantless

arrest, the United States Supreme Court has explained:




                                    - 16 -
J-A02021-15


      Because many situations which confront officers in the course of
      executing their duties are more or less ambiguous, room must
      be allowed for some mistakes on their part. But the mistakes
      must be those of reasonable men, acting on facts leading
      sensibly to their conclusions of probability. The rule of probable
      cause is a practical, nontechnical conception affording the best
      compromise that has been found for accommodating these often
      opposing interests. Requiring more would unduly hamper law
      enforcement.     To allow less would be to leave law-abiding
      citizens at the mercy of the officers’ whim or caprice.

                                      ***

      In dealing with probable cause, however, as the very name
      implies, we deal with probabilities. These are not technical; they
      are the factual and practical considerations of everyday life on
      which reasonable and prudent men, not legal technicians, act.

Brinegar v. United States, 338 U.S. 160, 175-76 (1949).

      To hold that a warrantless arrest is constitutional where the arresting

officer is without direct knowledge or reasonably trustworthy information

justifying it would be to ignore the “sensibl[e] . . . conclusions of probability”

made by reasonable people. Id. A reasonable arresting officer cannot reach

a sensible conclusion based upon facts that are beyond his or her

knowledge. The post hoc imputation of knowledge among police officers is

an exercise for “legal technicians,” not “reasonable and prudent men.” Id.

In the absence of any clear authority from the United States Supreme Court,

or from our own Supreme Court, we decline to revise this standard.

      Even if we were willing to adopt the horizontal collective knowledge

doctrine, it would not apply to the facts of the case before us.          As the

Commonwealth notes, the courts that have accepted this formulation impute

knowledge among police officers who are “functioning as a team.” Brief for


                                     - 17 -
J-A02021-15



Commonwealth at 10.        However, the horizontal collective knowledge

approach also requires “some degree of communication between the officer

who possesses the incriminating knowledge and the officer who does not.”

United States v. Banks, 514 F.3d 769, 776 (8th Cir. 2008); see also

United States v. Parra, 402 F.3d 752, 766 (7th Cir. 2005) (“Agent Hehr,

who arrested Correa, was in constant communication with Agent Becka

and Agent Chamulak.      On this basis, we find the collective knowledge

doctrine applicable[.]” (emphasis added)); United States v. Terry, 400

F.3d 575, 581 (8th Cir. 2005) (“We impute information if there has been

“some degree of communication” between the officers.” (emphasis

added)); United States v. Lee, 962 F.2d 430, 435 (5th Cir. 1992)

(“[P]robable cause can rest upon the collective knowledge of the police,

rather than solely on that of the officer who actually makes the arrest, when

there is ‘some degree of communication between the two.’” (emphasis

added)). Instantly, the suppression hearing transcript lacks any testimony

that Officer Gibson and Officer McCook communicated with each other.

Thus, even the expanded collective knowledge doctrine advocated by the

Commonwealth would not preclude suppression based upon the record

before us.

     Pennsylvania courts have never expanded the doctrine beyond the

situation where a police officer who possesses probable cause instructs a

fellow officer to act. See Queen, 639 A.2d at 446. We decline to adopt the

“horizontal” approach to collective knowledge, which some federal courts

                                   - 18 -
J-A02021-15



have used to aggregate knowledge among police officers functioning as a

team. In any event, even if Pennsylvania law recognized such a broad rule,

the absence of any evidence that Officers Gibson and McCook actually

communicated with one another would render the rule inapplicable to this

case.

        We understand the trial court’s temptation to infer that Officer McCook

instructed Officer Gibson to arrest Yong. When a police officer observes a

suspect engage in criminal conduct and then a second police officer arrests

the suspect, one might reasonably assume that the officers communicated

with one another. The testimony presented at Yong’s trial suggests that this

is what occurred.     See Notes of Testimony (“N.T.”), 4/22/2013, at 68-69

(“When I got in there I wanted to make sure that everybody was patted

down, so I told them to pat them down again. And Officer Gibson picked

[Yong] up . . . and then he started patting him down.”). Nevertheless, as a

matter of law, our scope of review in suppression matters is limited to the

suppression hearing record, and excludes any evidence elicited at trial. In

re L.J., 79 A.3d at 1085.

        The result we reach in this case is not a consequence of a hyper-

technical legal rule.      The collective knowledge doctrine unquestionably

authorizes police officers to act upon information or instructions from their

fellow officers. Whiteley, 401 U.S. at 568; Hensley, 469 U.S. at 231. At

Yong’s suppression hearing, it was the Commonwealth’s burden to establish

that    Officer   McCook   directed   Officer   Gibson   to   arrest   Yong.   See

                                       - 19 -
J-A02021-15



Pa.R.Crim.P. 581 (“The Commonwealth shall have the burden of going

forward with the evidence and of establishing that the challenged evidence

was not obtained in violation of the defendant’s rights.”). The suppression

record before us lacks any evidence to that effect.     We are compelled to

conclude that Yong’s arrest was unconstitutional.

      Because we cannot, based upon the state of this record, impute Officer

McCook’s knowledge that Yong had participated in a prior drug transaction to

Officer Gibson, we must conclude that Yong’s arrest and the subsequent

search of his person were unconstitutional. Accordingly, we reverse the trial

court’s order denying Yong’s motion to suppress.

      In his second issue, Yong challenges the sufficiency of the evidence

supporting his conviction for criminal conspiracy. Even though Yong’s first

claim entitles him to relief, we nonetheless are required to address his

challenge to the sufficiency of the evidence, because double jeopardy

principles would prohibit a retrial on the conspiracy charge in the event that

this issue has merit. Commonwealth v. Palmer, 751 A.2d 223, 227 (Pa.

Super. 2000).

      The standard we apply in reviewing the sufficiency of the
      evidence is whether viewing all the evidence admitted at trial in
      the light most favorable to the verdict winner, there is sufficient
      evidence to enable the fact-finder to find every element of the
      crime beyond a reasonable doubt. In applying the above test,
      we may not weigh the evidence and substitute our judgment for
      the fact-finder.   In addition, we note that the facts and
      circumstances established by the Commonwealth need not
      preclude every possibility of innocence. Any doubts regarding a
      defendant’s guilt may be resolved by the fact-finder unless the


                                    - 20 -
J-A02021-15


      evidence is so weak and inconclusive that as a matter of law no
      probability of fact may be drawn from the combined
      circumstances. The Commonwealth may sustain its burden of
      proof of proving every element of the crime beyond a reasonable
      doubt by means of wholly circumstantial evidence. Moreover, in
      applying the above test, the entire record must be evaluated and
      all the evidence actually received must be considered. Finally,
      the trier of fact while passing on the credibility of witnesses and
      the weight of the evidence produced, is free to believe all,
      part[,] or none of the evidence.

Commonwealth v. Pappas, 845 A.2d 829, 835-36 (Pa. Super. 2004)

(citation omitted). Additionally, in evaluating this claim, we do not review a

diminished record.   Commonwealth v. Smith, 568 A.2d 600, 603 (Pa.

1989); Commonwealth v. Parker, 644 A.2d 1245, 1247 (Pa. Super.

1994). Rather, we are required to consider all of the evidence that was

actually received, without consideration as to the admissibility of that

evidence or whether the trial court’s evidentiary rulings were correct. Smith

and Parker, supra.

      Section 903 of the Crimes Code provides as follows:

      (a) Definition of conspiracy.—A person is guilty of conspiracy
      with another person or persons to commit a crime if with the
      intent of promoting or facilitating its commission he:

         (1) agrees with such other person or persons that they or
         one or more of them will engage in conduct which
         constitutes such crime or an attempt or solicitation to
         commit such crime; or

         (2) agrees to aid such other person or persons in the
         planning or commission of such crime or of an attempt or
         solicitation to commit such crime.

18 Pa.C.S. § 903. Once the trier of fact finds that there was an agreement,

and that the defendant intentionally entered into the agreement, that

defendant may be liable for the overt acts committed in furtherance of the

conspiracy regardless of which co-conspirator committed the act.                   See

Commonwealth v. Wayne, 720 A.2d 456, 463-64 (1998).

      The essence of a criminal conspiracy, which distinguishes it from

accomplice liability, is an agreement between the co-conspirators.                 See

Commonwealth v. Lambert, 795 A.2d 1010, 1016 (Pa. Super. 2002).

However, “[a]n explicit or formal agreement to commit crimes can seldom, if

ever, be proved and it need not be, for proof of a criminal partnership is

almost invariably extracted from the circumstances that attend its activities.”

Commonwealth v. Johnson, 719 A.2d 778, 785 (Pa. Super. 1998) (en

banc) (citations omitted).           Therefore, where the conduct of the parties

indicates that they were acting in concert with a corrupt purpose, the

existence   of        a   criminal    conspiracy     may       properly   be   inferred.

Commonwealth v. Snyder, 483 A.2d 933, 942 (Pa. Super. 1984). Non-

exclusive circumstances that may establish proof of a conspiracy include:

(1) an association between alleged conspirators; (2) knowledge of the

commission of the crime; (3) presence at the scene of the crime; and (4)

participation    in   the   object    of   the   conspiracy.      Commonwealth v.

Swerdlow, 636 A.2d 1173, 1177 (Pa. Super. 1994).

      Instantly, there was ample evidence that Yong intentionally aided Vega

in selling marijuana. At trial, the Commonwealth presented evidence that,

                                           - 22 -
J-A02021-15



immediately after Yong accepted currency from the CI, Vega handed the CI

twelve packets of marijuana. Two days later, Yong was present when Vega

sold marijuana to an undercover officer, and was standing in the living room

of the residence when police executed a search warrant. Based upon this

evidence, the jury was free to conclude that Yong and Vega had an

agreement whereby Yong would screen and accept payment from potential

drug purchasers, while Vega would retrieve and dole out the narcotics.

Compare Commonwealth v. Murphy, 844 A.2d 1228 (Pa. 2004) (finding

sufficient evidence to support conviction for conspiracy to commit PWID

where appellant asked undercover officer if he was a “cop,” and then

introduced     him   to   his   co-conspirator     who   sold   the   officer   heroin).

Accordingly, Yong’s challenge to the sufficiency of the evidence is without

merit.9
____________________________________________

       In arguing that the evidence adduced at trial was “insufficient in both
volume and quality,” Yong appears to conflate his challenge to the
sufficiency of the evidence with a challenge to the weight of the evidence.
Brief for Yong at 22. The sum of Yong’s sufficiency argument is that the
evidence was insufficient because Officer McCook’s investigation report was
inconsistent with his later testimony at trial. This argument challenges the
credibility of the Commonwealth’s witness and, therefore, implicates the
weight of the evidence—a claim that Yong has failed to preserve for our
review. See Statement of Errors Complained of on Appeal, 8/1/2013, at 1
(“[The trial c]ourt erred by denying [Yong’s] post-verdict motion for a
judgment of acquittal where [Yong] argued that there was insufficient
evidence.” (emphasis added)). Accordingly, Yong has waived his challenge
to the weight of the evidence.       Pa.R.A.P. 1925(b)(4)(vi) (“Issues not
included in the [1925(b) statement] . . . are waived.”); see generally
Commonwealth v. Lord, 719 A.2d 306 (Pa. 1998).

reverse the trial court’s order denying Yong’s motion to suppress, and
