STATE of North Carolina
v.
Johnell PORTER and Keith Emerson Ross.
No. 129.
Supreme Court of North Carolina.
August 31, 1981.
*381 Scott T. Pollard, Charlotte, for defendant Johnell Porter.
Asst. Public Defender Lyle J. Yurko, Charlotte, for defendant Keith Emerson Ross.

*378 COPELAND, Justice.
Defendants argue numerous assignments of error on appeal. We have carefully considered each assignment and conclude that the trial court committed no error which would entitle either defendant to a new trial.

I
Although defendants submitted separate briefs, several issues are argued by both defendants. For the sake of clarity and convenience, we will first address those issues which are raised by both defendants.
Defendants first contend that the trial court erred in allowing State's witness Hal Martin to testify that the cash register at the Phillips 73 Store was difficult to open. Defendants argue that this testimony was an expression of opinion by a non-expert witness, and therefore inadmissible.
As a general rule, a witness may not give opinion evidence when the facts underlying the opinion are such that the witness can state them in a manner which will permit an adequate understanding of them by a jury and the witness is no better qualified than the jury to draw inferences and conclusions from the facts. State v. Sanders, 295 N.C. 361, 245 S.E.2d 674 (1978); State v. Watson, 294 N.C. 159, 240 S.E.2d 440 (1978). However, this Court has long held that despite the general rule prohibiting opinion evidence, a witness may employ "shorthand statements of fact" as a means of referring to matters about which he has previously testified. Such shorthand statements are admissible even though the witness must also state a conclusion or opinion in rendering them. State v. Yancey, 291 N.C. 656, 231 S.E.2d 637 (1977); State v. Sneeden, 274 N.C. 498, 164 S.E.2d 190 (1968); 1 Stansbury's North Carolina Evidence § 125 (Brandis Rev.1973). In the present case, Mr. Martin first testified that to open the cash register one must "put a dime in it" and hit the groceries and total keys, or one must punch the no sale key. His subsequent statement that the cash register was difficult to open was therefore a shorthand method of referring to his prior testimony, and defendants' objection to the statement was properly overruled.
Under similar reasoning, we likewise find defendants' next assignment of error without merit. Defendants maintain that the trial court erred in allowing Mr. Martin to testify that he had been "robbed," since such a statement was conclusory and involved a statement of opinion by the witness. Before making this statement Mr. Martin had testified that a gun had been held to his head, that he was forced to crawl on the floor, that he had been beaten over the head until rendered unconscious, and that money and several other items had been taken from the store. His later testimony that he had been "robbed" was thus properly admitted as a shorthand statement of the facts.
Defendants also allege that the trial court erred in denying their motions to dismiss on the ground that the evidence was insufficient to sustain their convictions. In ruling upon defendants' motion to dismiss, the trial court is required to interpret the evidence in the light most favorable to the State, drawing all reasonable inferences in the State's favor. State v. King, 299 N.C. 707, 264 S.E.2d 40 (1980); State v. Powell, 299 N.C. 95, 261 S.E.2d 114 (1980). The defendants' motion must be denied if the State has offered substantial evidence against defendant of every essential element of the crime charged. "Substantial evidence" is defined as that amount of relevant evidence that a reasonable mind might accept as adequate to support a conclusion. State v. Fletcher, 301 N.C. 709, 272 S.E.2d 859 (1981); State v. Smith, 300 N.C. 71, 265 S.E.2d 164 (1980). The test of the sufficiency *382 of evidence to withstand dismissal is the same whether the State's evidence is direct, circumstantial, or a combination of the two. State v. Cutler, 271 N.C. 379, 156 S.E.2d 679 (1967).
An armed robbery occurs when an individual takes or attempts to take personal property from the person of another, or in his presence, or from any place of business or residence where there is a person or persons in attendance, by the use or threatened use of a dangerous weapon, whereby the life of a person is endangered or threatened. G.S. 14-87. See also State v. Ballard, 280 N.C. 479, 186 S.E.2d 372 (1972); State v. Waddell, 279 N.C. 442, 183 S.E.2d 644 (1971). In the case sub judice, the defendants acknowledged that a robbery had taken place. The State presented evidence tending to show that Hal Martin was robbed at gunpoint by more than one person, that the persons who robbed him fled from the scene in a red Dodge Aspen, that at least one person fled from the Dodge into the woods at the end of a high speed chase by a county police officer, that police officers used a bloodhound to follow the trail of that person to a location where both defendants were found hiding under a bridge, and that a .32 caliber revolver was also found at that location. After considering this evidence in the light most favorable to the State, we find that there was substantial evidence presented of defendants' guilt on each material element of armed robbery. The determination of defendants' guilt or innocence was therefore a question to be answered by the jury, and the trial court did not err in denying defendants' motion to dismiss.
Defendants next argue that the trial court erred in failing to instruct the jury on common law robbery. As a general rule, when there is evidence of defendant's guilt of a crime which is a lesser included offense of the crime stated in the bill of indictment, the defendant is entitled to have the trial judge submit an instruction on the lesser included offense to the jury. State v. Redfern, 291 N.C. 319, 230 S.E.2d 152 (1976); State v. Bell, 284 N.C. 416, 200 S.E.2d 601 (1973). Common law robbery is a lesser included offense of armed robbery, and an indictment for armed robbery will support a conviction of common law robbery. State v. Black, 286 N.C. 191, 209 S.E.2d 458 (1974). Nevertheless, the trial judge is not required to instruct on common law robbery when the defendant is indicted for armed robbery if the uncontradicted evidence indicates that the robbery was perpetrated by the use or threatened use of what appeared to be a dangerous weapon. Justice Branch (later Chief Justice), speaking for the Court in State v. Thompson, 297 N.C. 285, 289, 254 S.E.2d 526, 528 (1979), set forth the test for determining when an instruction on common law robbery is required as follows:
"We conclude that when the State offers evidence in an armed robbery case that the robbery was attempted or accomplished by the use or threatened use of what appeared to the victim to be a firearm or other dangerous weapon, evidence elicited on cross-examination that the witness or witnesses could not positively testify that the instrument used was in fact a firearm or dangerous weapon is not of sufficient probative value to warrant submission of the lesser included offense of common law robbery. When a person perpetrates a robbery by brandishing an instrument which appears to be a firearm, or other dangerous weapon, in the absence of any evidence to the contrary, the law will presume the instrument to be what his conduct represents it to be  a firearm or other dangerous weapon."
See also State v. Rivens, 299 N.C. 385, 261 S.E.2d 867 (1980).
In the case before us, Mr. Hal Martin testified that all he observed during the incident before being rendered unconscious was the barrel of a gun, held at his forehead. There is no evidence in the record to contradict this testimony. We therefore presume the instrument described by Mr. Martin to be a firearm, and hold that the trial court properly refused defendants' request for an instruction on common law robbery.


*383 II
We next address those issues argued solely by defendant Porter.
Porter contends that the trial court erred in denying his motion to participate as co-counsel at his trial, in violation of his constitutional right to represent himself, guaranteed by the Sixth Amendment to the United States Constitution. The Sixth Amendment, made applicable to the states by the Fourteenth Amendment, guarantees the accused in a State criminal action the right to proceed without counsel and represent himself at trial when he voluntarily and knowingly elects to do so. Faretta v. California, 422 U.S. 806, 95 S.Ct. 2525, 45 L.Ed.2d 562 (1975); State v. Robinson, 290 N.C. 56, 224 S.E.2d 174 (1976). Defendant Porter urges us to interpret the holding of the United States Supreme Court in Faretta v. California, supra, as establishing not only the right to represent oneself in a criminal action, but also as establishing the right of an accused to represent himself as co-counsel with an attorney. This Court has previously held in State v. House, 295 N.C. 189, 244 S.E.2d 654 (1978), that the Faretta decision extends only to an accused's right to forego all assistance of counsel and does not create a right to be simultaneously represented by himself and an attorney. We reaffirmed this holding in State v. Parton, ___ N.C. ___, 277 S.E.2d 410 (1981). It is clear that in this jurisdiction, an accused has the right to appear in propria persona or, in the alternative, by counsel. Since defendant Porter elected to retain the services of his court-appointed attorney, the trial court properly denied his motion to participate as co-counsel, and his allegations to the contrary are without merit.
By his next assignment of error, defendant submits that the trial court erred in granting the State's motion to join his case with defendant Ross' case for trial, and erred in denying his motion to sever. G.S. 15A-926(b)(2)a provides that the charges against two or more defendants may be joined for trial when each of the defendants is charged with accountability for each offense joined. Since both defendants in the case before us were charged with accountability for the same armed robbery, the armed robbery charges against them were properly joined for trial.
Nevertheless, defendant complains that the consolidation prevented him from obtaining a fair trial, and therefore his motion to sever should have been granted pursuant to G.S. 15A-927(c)(2)a. The decision to join the charges against two or more defendants for trial is within the sound discretion of the trial judge and will not be disturbed on appeal absent an abuse of that discretion. The defendant seeking to overturn the discretionary ruling must show that the joinder has deprived him of a fair trial. State v. Slade, 291 N.C. 275, 229 S.E.2d 921 (1976); State v. Alford, 289 N.C. 372, 222 S.E.2d 222 (1976), death sentence vacated 429 U.S. 809, 97 S.Ct. 46, 50 L.Ed.2d 69 (1976).
Defendant Porter contends that had the parties been tried separately, Mr. Martin's testimony that he saw a man not fitting Porter's description leave the Dodge and run into the woods would not have been admissible against him, and that the admission of this testimony deprived him of a fair trial. We disagree. Mr. Martin's testimony would be admissible against defendant Porter in any event as the witness' personal observation of one of the events taking place during the incident, which observation is relevant as tending to prove a fact in issue, the identity of the robbers. See Cross v. Beckwith, 293 N.C. 224, 238 S.E.2d 130 (1977); State ex rel. Freeman v. Ponder, 234 N.C. 294, 67 S.E.2d 292 (1951). We fail to understand how defendant Porter could be prejudiced by the admission of this evidence which tended to prove that he was not the individual who fled from the Dodge. Such testimony would be more favorable to him than prejudicial. Defendant's assignment of error is without merit and overruled.
Porter next argues that the trial court committed prejudicial error in denying his request for a transcript of the grand *384 jury proceedings concerning his indictment. An accused in this jurisdiction has no right to obtain a transcript of the grand jury proceedings against him. Such proceedings are considered "secret." G.S. 15A-623. Defendant is adequately protected by his right to object to improper evidence and cross-examine the witnesses presented against him at trial. See generally United States v. Kernodle, 367 F.Supp. 844 (M.D.N. C.1973).
Defendant Porter also maintains that the trial court erred in admitting the evidence relating to the tracking by a bloodhound. Before the conduct of bloodhounds will be received into evidence it must be shown:
"(1) That they are of pure blood, and of a stock characterized by acuteness of scent and power of discrimination; (2) that they possess these qualities, and have been accustomed and trained to pursue the human track; (3) that they have been found by experience reliable in such pursuit; (4) and that in the particular case they were put on the trail of the guilty party, which was pursued and followed under such circumstances and in such way as to afford substantial assurance, or permit a reasonable inference, of identification." State v. McLeod, 196 N.C. 542, 545, 146 S.E. 409, 411 (1929).
Porter contends that since the dog handler who testified at trial could not establish the pedigree of the dog that tracked him, the first element specified in McLeod was not established. It is defendant's position that to show "pure blood," the dog's registration papers must be introduced into evidence. Defendant's allegation was squarely rejected by this Court in State v. Rowland, 263 N.C. 353, 139 S.E.2d 661 (1965). In that case Justice Sharp (later Chief Justice), speaking for the Court, set forth the test for determining "pure blood" as follows:
"In practice, if the dog has been identified as a bloodhound, it has been the conduct of the hound and other attendant circumstances, rather than the dog's family tree, which have determined the admissibility of his evidence.
We find no North Carolina cases, and defendant has cited us to none, in which bloodhound evidence has been excluded for a deficiency in the proof of the bloodhound's pedigree if he is shown to be naturally capable of following the human scent, i. e., that he is a bloodhound, and if the evidence is corroborative of other evidence tending to show defendant's guilt." 263 N.C. at 359, 139 S.E.2d at 665.
It is thus sufficient if the dog's owner or handler identifies the dog as a bloodhound and the dog justifies this description by his performance. In the case sub judice the handler of the dog that tracked defendant testified that he was familiar with the dog's lineage and that he was a pureblood bloodhound. He further stated that the dog had been trained to follow the human scent and had successfully done so on at least 60 prior occasions. We find this testimony adequate to establish the dog's "pure blood" under the holding in Rowland, and defendant's allegations to the contrary are overruled.
The thrust of defendant Porter's case on appeal is his contention that the trial court erred in denying his motion to suppress the incriminating statements he made at the time of his arrest. Porter maintains that his statements were elicited by a custodial interrogation from law enforcement officers before he was advised of his constitutional rights, and are therefore inadmissible under the holding of Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966). There is no question but that defendant Porter's statements were rendered after he was taken into custody and before he was advised of his constitutional rights. The question for our determination is thus whether Porter's statements were given in response to an "interrogation" by law enforcement officers which would bring his statements under the exclusionary rule established in Miranda. We agree with the majority of the Court of Appeals that the dialogue at issue in this case between defendant Porter and police officers can not be characterized as an "interrogation," and therefore Porter's statements were properly admitted into evidence against him.
*385 The conversation to which defendant Porter objects transpired immediately after both defendants were apprehended and handcuffed. Officer Wilson radioed his supervisor to inform him that two suspects had been taken into custody. The supervisor asked Officer Wilson if he had recovered a bank bag. Defendant Porter heard the question over the radio and stated, "The bank bag is in the car." Officer Wilson then asked "What bank bag?", to which Porter replied, "The bag from the robbery."
When the State offers a defendant's incriminating statement into evidence and defendant objects, the trial court must conduct a voir dire hearing to determine its admissibility. State v. Jones, 294 N.C. 642, 243 S.E.2d 118 (1978). The trial judge's finding after the voir dire hearing that an inculpatory statement was freely and voluntarily given is conclusive on appeal when supported by competent evidence. State v. Parton, supra, State v. Boykin, 298 N.C. 687, 259 S.E.2d 883 (1979). In the case before us, a voir dire hearing was held to determine the admissibility of Porter's inculpatory statements, after which the trial court found that the statements were spontaneous utterances, voluntarily given, and not in response to an in-custody interrogation within the meaning of Miranda.
The Court in Miranda expressly noted that not all statements obtained by the police after a person has been taken into custody are to be considered the product of an interrogation, stating:
"Confessions remain a proper element in law enforcement. Any statement given freely and voluntarily without any compelling influences is, of course, admissible in evidence. The fundamental import of the privilege while an individual is in custody is not whether he is allowed to talk to the police without the benefit of warnings and counsel, but whether he can be interrogated. There is no requirement that police stop a person who enters a police station and states that he wishes to confess to a crime, or a person who calls the police to offer a confession or any other statement he desires to make. Volunteered statements of any kind are not barred by the Fifth Amendment and their admissibility is not affected by our holding today." 384 U.S. at 478, 86 S.Ct. at 1630, 16 L.Ed.2d at 726.
Porter's initial statement that "the bank bag is in the car" was clearly the type of volunteered statement expressly excluded from the Miranda holding. The question by Officer Wilson's supervisor was addressed to Officer Wilson, not to defendant. Porter's response was spontaneous and voluntary, and therefore admissible despite the fact that he had not yet been informed of his constitutional rights.
We further hold that the question Officer Wilson addressed to defendant, "What bag?", did not convert the dialogue into an "interrogation" within the meaning of Miranda. As we said in State v. Haddock, 281 N.C. 675, 682, 190 S.E.2d 208, 212 (1972):
"[a] voluntary in-custody statement does not become the product of an `in-custody interrogation' simply because an officer, in the course of appellant's narration, asks defendant to explain or clarify something he has already said voluntarily."
Thus, where a defendant voluntarily stated that he committed a murder, and a law enforcement officer asked him to "explain what happened," the Court held that the officer's statement did not convert the conversation into an "interrogation," and defendant's subsequent statements were admissible despite the absence of Miranda warnings. State v. McZorn, 288 N.C. 417, 219 S.E.2d 201 (1975), death sentence vacated 428 U.S. 904, 96 S.Ct. 3210, 49 L.Ed.2d 1210 (1976). Likewise, where defendant ran up to a burning building and said to a uniformed police officer, "I didn't mean for it to happen like this," the police officer's request to explain what she meant by that statement did not constitute an "interrogation" rendering defendant's subsequent confession inadmissible. State v. Freeman, 295 N.C. 210, 244 S.E.2d 680 (1978). The principle that emerges from these decisions is that to constitute an "interrogation" within the meaning of Miranda, the conduct of the *386 police must involve a measure of compulsion. "Interrogation" involves a procedure designed to elicit a statement from the individual at whom it is directed. An officer's request in the heat of an emotional situation that the accused explain or clarify a volunteered statement is not a procedure designed to elicit an inculpatory response.
Applying these principles to the facts of the case sub judice, it is apparent that Officer Wilson's question, "What bag?", was a request that Porter explain his previous statement, which request was an immediate response in an emotional situation, made before Officer Wilson had the opportunity to form a design or motivation to elicit incriminating statements from Porter. Consequently, under the prior decisions of this Court, Officer Wilson's question did not transform the situation into an "interrogation," and defendant's subsequent statements are admissible in the absence of Miranda warnings.
Defendant submits, however, that our prior decisions have been modified by the United States Supreme Court's decision in Rhode Island v. Innis, 446 U.S. 291, 100 S.Ct. 1682, 64 L.Ed.2d 297 (1980). In that case, the Court was called upon to address for the first time the meaning of "interrogation" as it was employed in Miranda, and defined the term as follows:
"We conclude that the Miranda safeguards come into play whenever a person in custody is subjected to either express questioning or its functional equivalent. That is to say, the term `interrogation' under Miranda refers not only to express questioning, but also to any words or actions on the part of the police (other than those normally attendant to arrest and custody) that the police should know are reasonably likely to elicit an incriminating response from the suspect. The latter portion of this definition focuses primarily upon the perceptions of the suspect, rather than the intent of the police. This focus reflects the fact that the Miranda safeguards were designed to vest a suspect in custody with an added measure of protection against coercive police practices, without regard to objective proof of the underlying intent of the police. A practice that the police should know is reasonably likely to evoke an incriminating response from a suspect thus amounts to interrogation. But, since the police surely cannot be held accountable for the unforeseeable results of their words or actions, the definition of interrogation can extend only to words or actions on the part of police officers that they should have known were reasonably likely to elicit an incriminating response." 446 U.S. at 300-02, 100 S.Ct. at 1689-90, 64 L.Ed.2d at 307-08.
It is Porter's position that Officer Wilson "should have known" that his question was likely to elicit an incriminating response, and thus it was "interrogation" within the definition set forth in Innis. We believe defendant Porter's argument ignores the language in Innis which emphasizes that the holding in Miranda was designed to protect an accused from coercive police practices. The facts and holding of Innis reflect this emphasis. In that case, a body was discovered in the vicinity of a school for handicapped children. It was determined that the individual died as a result of wounds received from a shotgun blast. Defendant was arrested near the school and taken to police headquarters in a police vehicle. During the drive, two of the patrolmen who arrested defendant spoke with each other concerning the possibility that one of the handicapped children from the nearby school might find a weapon and get hurt. Defendant overheard the conversation and volunteered to show the patrolmen where the shotgun was located. The Court found that the patrolmen had no reason to know that their conversation was likely to elicit an inculpatory response, therefore it did not constitute an "interrogation" within the meaning of Miranda. It is difficult to discern how the question asked by Officer Wilson could be any more likely to invoke an incriminating response than was the conversation involved in Innis. Officer Wilson voiced his question as an immediate response to Porter's spontaneous utterance, without the opportunity to reflect or to *387 consider whether his query was reasonably likely to elicit an inculpatory remark. There was no evidence of any coercive practice on the part of the law enforcement officers beyond that inherent in the arrest itself. Under the circumstances present in this case, we hold that the officer had no reason to know that his question was "likely to elicit an incriminating response" within the meaning of Innis. Consequently, the definition of "interrogation" in Innis does not apply to bring the conversation at issue within the holding of Miranda, and defendant Porter's motion to suppress was properly denied.

III
We finally address those arguments presented by defendant Ross.
Defendant Ross contends that the trial court erred in denying his motion to suppress the inculpatory statements made by codefendant Porter at the time of his arrest. Specifically, he argues that since defendant Porter elected not to testify at trial, the admission of these statements violated his right, as guaranteed by the Sixth Amendment of the United States Constitution, to confront the witnesses against him. We disagree and hold that, under the particular facts and circumstances of this case, defendant's constitutional right of confrontation was not violated by the admission of the challenged evidence. Consequently, defendant Ross is not entitled to a new trial on this basis.
In essence, defendant Ross argues that the trial court's admission of Porter's statements violated the decision of the Supreme Court in Bruton v. United States, 391 U.S. 123, 88 S.Ct. 1620, 20 L.Ed.2d 476 (1968). In Bruton, the Court held that where one codefendant made extrajudicial statements implicating the other and the declarant elected not to testify at trial, the nondeclarant's constitutional right to confront his accuser was violated by the introduction of those statements at their joint trial. Significantly though, the Court also emphasized that the declarant's statements were hearsay and not admissible against the non-declarant codefendant under any of the recognized exceptions to the hearsay rule. 391 U.S. at 128 n.3, 88 S.Ct. at 1623-24 n. 3, 20 L.Ed.2d at 480-81 n. 3. Thus, Bruton stands for the general proposition that the admission of a codefendant's extrajudicial statements against the non-declarant violates the Confrontation Clause of the Sixth Amendment if two circumstances simultaneously co-exist: (1) the statements inculpate the non-declarant and (2) the statements do not fall within an exception to the hearsay rule. It is in this light that we must examine Porter's statements to determine whether their admission deprived Ross of any constitutional right.
In the first instance, we believe that Porter's statements did, in fact, inculpate Ross. Officer Wilson testified at the voir dire hearing that when he asked Porter "What bank bag?", Porter responded, "The bag we got from the robbery." Though the trial court redacted the statement and allowed Officer Wilson to testify that Porter had said, "The bag from the robbery," the deletion of an express reference to defendant Ross was insufficient to absolve the statements of any incriminating implications as to Ross's guilt. The two defendants were tracked by a bloodhound and found hiding together under a bridge about a mile from the location at which they entered the woods, and a gun was also found nearby. Moreover, Porter and Ross had both been arrested when Porter made the damaging statement. Under such circumstances, the jury could readily infer that Porter meant to incriminate Ross, as well as himself, by the statement, "The bag from the robbery."
In the second instance, however, we are persuaded that Porter's statements fit within an exception to the hearsay rule. For, it is well established that "[w]hen a startling or unusual incident occurs, the exclamations of a participant or a bystander concerning the incident, made spontaneously and without time for reflection or fabrication, are admissible." 1 Stansbury, N.C. Evidence § 164, at 554 (Brandis rev. 1973). The record in the instant case reveals that there was a spirited chase and *388 the tracking of at least one of the defendants with bloodhounds; that defendants were found under a bridge by Officer Wilson and arrested; that a voice came over the officer's walkie-talkie asking him if a bank bag had been recovered; that defendant Porter reacted to the stimulus by saying "The bag is in the car"; that Officer Wilson then asked "What bank bag?"; and that defendant Porter replied "The bag we got from the robbery." [As previously indicated, the trial judge subsequently edited this final statement by eliminating the words "we got."] Thus, we believe Porter's exclamations, made almost immediately after the defendants' apprehension and arrest and in direct response to the unusual stimulus of a question addressed to another over a radio, constituted "spontaneous utterances" and as such were admissible against Ross as an exception to the hearsay rule.
It has been noted that the Confrontation Clause and the hearsay rule "stem from the same roots" and are "designed to protect similar values." Dutton v. Evans, 400 U.S. 74, 91 S.Ct. 210, 27 L.Ed.2d 213 (1970); California v. Green, 399 U.S. 149, 90 S.Ct. 1930, 26 L.Ed.2d 489 (1970). In accordance with that view, this Court has consistently held that statements which fall under exceptions to the hearsay rule may be admitted against codefendants without violating the Confrontation Clause. See State v. Stevens, 295 N.C. 21, 243 S.E.2d 771 (1978) (dying declarations); State v. Hardy, 293 N.C. 105, 235 S.E.2d 828 (1977) (implied admissions). However, the particular facts of each case must be carefully examined by the courts to determine whether an accused's right of confrontation was violated whenever the extrajudicial statement of a codefendant declarant, who is not available for cross-examination, is offered as evidence of the accused's guilt under an exception to the hearsay rule. Dutton v. Evans, supra; United States v. Carlson, 547 F.2d 1346 (8th Cir. 1976). In this regard, the United States Supreme Court has recently held that merely classifying a statement as a hearsay exception does not automatically satisfy the requirements of the Sixth Amendment and that hearsay testimony is admissible against the accused, without violating his right of confrontation, only when it bears adequate "indicia of reliability" to guarantee its trustworthiness. Ohio v. Roberts, 448 U.S. 56, 100 S.Ct. 2531, 65 L.Ed.2d 597 (1980).
We have already indicated that Porter's statements, though hearsay, were admissible against defendant Ross as spontaneous utterances. We further hold that this hearsay testimony was inherently reliable[1] due to the very nature of its spontaneity.
"[S]uch statements derive their reliability from their spontaneity when (1) there has been no sufficient opportunity to plan false or misleading statements, (2) they are impressions of immediate events and (3) they are uttered while the mind is under the influence of the activity of the surroundings." State v. Deck, 285 N.C. 209, 214, 203 S.E.2d 830, 833-34 (1974); State v. Johnson, 294 N.C. 288, 291, 239 S.E.2d 829, 830-31 (1978).
The reliability of Porter's statements are additionally enhanced by the unusual character of the overall surrounding events which culminated in the defendants' arrests and triggered the incriminating exclamations. In sum, upon this record, we are compelled to conclude that defendant Ross's right of confrontation was not violated by the trial court's admission of the testimony complained of at the defendants' joint trial.
In his only remaining assignment of error, defendant Ross contends that the trial court erred in granting the State's motion to join both him and Porter for trial and in denying his motion for severance. At the outset, defendant admits that the cases were properly joined for trial under G.S. 15A-926(b)(2)a because Porter and he *389 were charged with accountability for the same offense, the armed robbery. He nevertheless maintains that the joinder was improper under G.S. 15A-927(c)(1) and essentially contends that he was unfairly prejudiced by the admission of Porter's statements at their joint trial because, had he been tried separately, this evidence would have been excluded. This contention cannot be sustained.
G.S. 15A-927(c)(1) requires the prosecutor to select one of three courses of action "[w]hen a defendant objects to joinder of charges against two or more defendants for trial because an out-of-court statement of a codefendant makes reference to him but is not admissible against him...." (Emphasis added.) The trial court's joinder of the charges is not subject to attack on the basis of this subsection since we have ruled that Porter's extrajudicial statements were indeed admissible against defendant under the spontaneous utterance exception to the hearsay rule.
Defendant finally asserts that the joinder was improper under G.S. 15A-927(c)(2)b. That statute requires the judge to deny a joinder for trial or grant a defendant's motion to sever when "it is found necessary to achieve a fair determination of the guilt or innocence of that defendant." As we have already stated in addressing the similar contention of defendant Porter, the decision to join the charges against two or more defendants rests within the trial judge's sound discretion, and we may not disturb that decision on appeal unless defendant adequately demonstrates the existence of an abuse of discretion. State v. Slade, supra; State v. Alford, supra. It suffices to say that we are not persuaded that joinder in this case deprived defendant Ross of a fair trial. The assignment of error is consequently overruled.
For the foregoing reasons, the convictions of these defendants must be upheld.
The decision of the Court of Appeals is affirmed.
AFFIRMED.
NOTES
[1]  In Ohio v. Roberts, supra, the Supreme Court indicated that a sufficient inference of reliability can be made "without more" from the showing that the challenged evidence falls within "a firmly rooted hearsay exception." 448 U.S. at 66, 100 S.Ct. at 2539, 65 L.Ed.2d at 608. The hearsay exception for spontaneous utterances is firmly rooted in North Carolina. See 1 Stansbury, N.C. Evidence § 164 (Brandis rev. 1973).
