On March 23, 1977, appellant was convicted, by a jury, of Third Degree Murder. Post verdict motions were filed and denied. Appellant was initially sentenced to ten to twenty years imprisonment; however, this was subsequently reducеd to six to fourteen years, following the filing of a petition for reconsideration of sentence.
The facts incident to this appeal are as follows:
On August 19, 1976, Eyell Copeland, the victim, and appellant went shopping. They returned to their Chester, Pennsylvania home, owned by appellant’s sister, later that afternoon. At approximately 9:30 p. m. appellant decided to drive to North Carolina in his sister’s car. Copeland told appellant that he could not dо this since he did not have his sister’s permission to so use the car. To prevent appellant from taking thе car, Copeland removed the starter coil. This prompted appellant to run inside the house and grab a butcher knife. Moments later he returned and stabbed Copeland in the chest. Shortly thereaftеr, Copeland was taken to a hospital by Chester police officers. An emergency operation proved unsuccessful and Copeland was pronounced dead. The police officers returned to the scene of the stabbing and found appellant with the knife in his hand. He was immediately takеn into custody. After having been read his rights, appellant gave a statement to police in which he admitted the stabbing. This statement was the subject of a suppression hearing wherein it was ruled admissible.
*576 On appeal, appellant questions the sufficiency of the evidence, and the use, by the Commonwealth, of аppellant’s alleged written statement for impeachment purposes. In his “Statement of Questions”, a third issue is presented involving a possible Pa.R.Crim.P.: Rule 1100 violation, however, this issue is not briefed, and therefore, wе will not consider it.
It is axiomatic that the test for sufficiency of the evidence is “whether, acceрting as true all the evidence, together with all reasonable inferences therefrom upon which thе jury could properly have based its verdict, such evidence and inferences are sufficient in law to prove guilty beyond a reasonable doubt.”
Commonwealth v. Carbonetta,
Appellant initially alleges that the evidence is insuffiсient because the Commonwealth failed to prove an essential element of the crime, sрecifically, causation. Appellant argues that because the question presented to thе Medical Examiner at trial was couched in the language “can you give an opinion with reasonable medical certainty as to cause of death”, this made the response by the Doctor that “The cause of death was a stab wound of the thorax, or chest” not sufficient evidence to provе cause of death beyond a reasonable doubt. This argument is entirely specious. It was incumbent upоn the Commonwealth to prove that the victim’s death was caused by a criminal agency. The medicаl examiner’s statement that a stab wound was the legal cause of death, coupled with the testimony оf other witnesses that appellant, in fact, caused the stab wound, was clearly sufficient evidence from which the jury could determine causation beyond a reasonable doubt. Appellant cites
Commonwealth v. Embry,
Appellant further alleges that the evidence is insufficient in that his own testimony of self defense was enough to rebut the Commonwealth’s case, and therefore, the jury verdict was against the weight of the evidence. However, it is within the province of the trier of fact to pass upon the credibility of witnesses and the weight to be accorded the evidence produced.
Commonwealth v. Alston,
Appellant next argues that the trial court erred in permitting the jury to consider testimony concerning his written statement when this statement was never offered into evidence by the Commonwealth. However, upon examination of the trial record, no objection was made by defense counsel to the use of this statement by the district attorney during cross examination. Therefore, the specific objection now presented involving admissibility is waived. Furthermore, inadmissible evidence, admitted without objection, may be deemed admissible if this evidence is relevant and material to a fact in issue. See
Commonwealth v. Ehley,
Based on the foregoing, judgment of sentence is affirmed.
