This is an appeal from a conviction for aggravated assault. The primary question presented is whether
Commonwealth v. Bennett,
At approximately seven o’clock in the morning on October 5, 1977, in Philadelphia, Pennsylvania, Edward Owens heard a knock at the door of his residence. Since Mr. Owens was unclothed, he went to the kitchen on his way to the bath *266 room and shouted “come on in.” Apparently within moments thereafter, Owens was stabbed in the upper portion of the left side of his chest. Debbie Monoghan, who at this time was present in another area of the Owens’ household, came to Owens’ aid upon hearing his pleas for help. Since there was no telephone in the Owens’ housе, Ms. Monoghan went to a fire station across the street in order to call for assistance. However, no more than 10 or 15 minutes elapsed between the stabbing and the arrival of the paramedics. Almost immediatеly thereafter, as two paramedics were placing Mr. Owens in the ambulance, Officer L. Thomas Szelagowski arrived on the scene.
Before questioning Mr. Owens, Officer Szelagowski observed that most of Owens’ upper abdomen was covered with blood, indicating Owens had faced his assailant, and was informed that Owens’ condition was serious. During Szelagowski’s conversation with Owens, Owens is alleged to have unequivocally stated that the police should “get” Joseph LaRosa, a friend of Owens' because he was the perpetrator of the assault.
Later that same morning Officer Frank Mondrosch apprehended LaRosa who, after receiving the appropriate Miranda warnings, gave Mondrosch a statement. At trial Officer Mondrosch testified that LaRosa admitted having been in Owens’ house earlier that morning, but denied having stabbed Owens. LaRosa had stated the purpоse of his visit was to laugh at Owens, presumably tauntingly, for allegedly having attacked LaRosa’s girlfriend, firing a gun at her on several occasions, and having threatened LaRosa. LaRosa also accused Owens somewhаt incredibly, of being a “junkie” who sometimes kept girls bound in his house for several days so he could burglarize their homes. Obviously, to the extent that LaRosa’s statement was credible it was partially exculpatory, containing as it did his denial of being Owens’ assailant. On the other hand, his statement was inculpatory insofar as it placed LaRosa at the scene of the crime approximately at the time it was committed, and established a motive for LaRosa’s assaulting Owens.
*267 LaRosa was subsequently charged with and brought to trial for the crimes of simple assault, 1 aggravated assault, 2 and possession of instruments of crime. 3 During LaRosa’s non-jury trial, Owens’ inculpatory statement to Officer Szelagowski was admitted over timely objection that it did not qualify as an “excited utterance.” At the conclusion of the trial, LaRosa was found guilty of only aggravated assault. Timely motions for new trial and in arrest of judgment having been filed, argued and denied by the lower сourt, this appeal ensued.
As mentioned above, appellant relies primarily upon
Commonwealth v. Bennett,
In the first place, Owens’ excited utterance was not, as appellant contends, thе only evidence linking appellant to the crime. As indicated above, appellant’s statement to Officer Mondrosch at the time of his arrest established that appellant had gone to Owens’ house on thе morning of the stabbing to taunt Owens, and that appellant had a motive for committing the crime. 5 Motive and opportunity, while not always necessary to prove, are always relevant to establish the identity of the рerpetrator of the crime. See generally 10A P.L.E., Criminal Law §§ 291, 401 (1970). Consequently, appellant’s assertion that Owens’ excited utterance was the only evidence tending to prove appellant was the assailant is simply a misstatement of the record.
Second, appellant’s assertion that Owens’ testimony at trial contradicted his excited utterance is also inaccurate. Although it is true that Owens was unable to testify at trial thаt appellant had stabbed him, despite his positive identification of appellant minutes after the crime, neither did Owens’ testimony tend to exonerate appellant. In this regard, Owens testified as follows:
Cross Examination
Q.: Do you know Joseph LaRosa?
A.: Yes, I know him.
Q.: Did he stab you?
A.: No, sir, not that I know of.
Mr. Reif [defense counsel]: That is all. No questions.
The Court: What do you mean, sir, when you say, ‘not that I know of’?
*269 A.: I mean by saying that that I do not know who stabbed me.
Obviously, Owens did not contradict the substance of his excited utterance, he merely testified that he had no present recollеction of whom his assailant had been. Consequently, Owens’ testimony at trial did not weaken the probative force his excited utterance otherwise would have had standing alone. Cf., Annot.,
Having demonstrated the fallacy of the factual predicates upon which appellant’s analogy of this case to
Bennett
rests, it is nevertheless necessary to determine whether the Commonwealth’s evidence was sufficient to prove аppellant’s guilt beyond a reasonable doubt. In undertaking this task, we are mindful that it is the exclusive function of the trier of fact to assess the credibility of the witnesses; and the trial judge was free to believe some, none or all of the evidence presented by the Commonwealth or appellant. See, e. g.,
Commonwealth
v.
Hinchcliffe,
As noted above, appellant relies in large part upon the case of
Commonwealth
v.
Bennett,
As we took pains to establish earlier, Owens’ testimony at trial did not contradict the substance of his excited utterance which, itself, was fortified by appellant’s statement given to Officer Mondrosch at the time of his arrest. Furthermore, the trial judge had a perfectly sound basis for crediting the victim’s excited utterance and Officer Mondrosch’s testimony, while disregarding Owens’ testimony of lapse of memory. 6 First, Owens admitted that appellant was his friend, a friendship Owens may have chosen to honor when his anger had сooled. Second, appellant’s statement to Officer Mondrosch included allegations that Owens, himself, was a criminal who practiced burglary, as well as false imprisonment, to satisfy his drug addiction. This Damoclean threat offered an added inducement for Owens to discharge his duty in friendship by silence.
In any event, the inherent reliability of an excited utterance derives from the circumstances which provoked it,
*271
and its credibility does not depend upon its corroboration or restatement in court. See
Commonwealth v. Pronkoskie,
Judgment of sentence affirmed.

. Appellant has apparently conceded that the Commonwealth is correct in its assertion that the Owens’ statement qualified as an “excited utterance” and was, therefore, initially admissible as an exception to the hearsay rule. See
Commonwealth v. Pronkoskie,
. Additionally, although Owens’ girlfriend did not identify appellаnt at the trial, she testified that she had been alerted by Owens’ cries for help during the assault, and had seen a white male in the house who ordered her to return upstairs.
. The trial judge noted in his opinion that Owens’ testimony may have been fabricated.
