Opinion by
On May 21, 1970, the appellant, John Frederick Nole, was convicted by a jury of first degree murder. Subsequently he received a sentence of life imprisonment. Post-trial motions were denied and this appeal followed. We affirm.
The charges against appellant arose out of the death in Philadelphia on February 22, 1969 of Joseph Shayka, an 81-year-old storekeeper. Shortly after his apprehension on September 2, 1969, appellant gave homicide detectives a complete, signed confession, detailing his participation in the events leading up to Shayka’s death. A pretrial motion to suppress this confession was denied, and that ruling is not now challenged. By his own admission, corroborated by the victim’s widow, who was an eyewitness to the happenings, the following transpired. At approximately 5:00 P.M. of the day Sliayka died, appellant, then aged 17, and two other *64 juveniles entered the deceased’s grocery and candy store. Appellant carried a loaded revolver and one of his companions was armed with a knife. When his demands for cash were met with hesitation, appellant jabbed the old storekeeper four times in the stomach, twice with his hands and a like number with the revolver barrel. The three youths then seized some loose change and cigarettes and fled as Shayka slumped to the floor. He was pronounced dead on arrival at a hospital at 5:25 P.M.

It is well established that in a homicide case the Commonwealth must prove beyond a reasonable doubt that (1) a death has occurred; (2) the death resulted from a criminal agency; and (3) the defendant is legally responsible for the death.
Commonwealth v. Thomas,
The Commonwealth called Dr. Marvin Aronson, Assistant Medical Examiner (now Medical Examiner) for the City of Philadelphia. 1 He testified that Joseph Shayka had died from a ruptured arteriosclerotic *65 aneurysm of the abdominal aorta; that this rupture was recent, i.e., within eight to ten hours of death; and that it had Jed to a blood loss of approximately one quart. In laymen’s terms, Dr. Aronson positioned the fatal interna] injury at the level of the navel and gave as his expert opinion that death resulted from a poke or punch in the stomach inflicted with a pistol or fist. The witness admitted that a sudden rise in blood pressure, a fall on the area of the aneurysm, or even a bending over were possible causes of the fatal injury. When pressed on cross-examination, however, Dr. Aronson gave the following response: “Anything is possible. However, the close time relationship between the collapse of this individual and the events described prior to that collapse, make it obvious that there is a relationship between these two factors .... [A]s I understand your question, sir, you are asking me if by coincidence at the same time that the deceased in this case suffered some injury that he could have by coincidence ruptured his aorta at that time, my answer is, yes, anything is possible but I consider that possibility in the realm of speculation or absurdity.” (Emphasis added.)
The law imposes upon the Commonwealth the burden of proving the defendant guilty beyond a reasonable doubt, not beyond all doubt. As we said in
Commonwealth v.
Libonati,
II.
On September 11, 1969, nine days after his arrest, appellant was brought before a judge of the Juvenile Branch of the Family Court Division of the Court of Common Pleas of Philadelphia. Counsel was appointed at that time 2 from the Office of the Public Defender and following a hearing appellant was bound over as an adult to the District Attorney for action by the grand jury on a general charge of murder.
Appellant would have us invalidate this preliminary proceeding on either of two grounds: (1) that his counsel’s cross-examination of the Commonwealth’s wit *67 nesses was ineffective; or (2) that he was denied due process of law because Ms parents were not formally notified of the charges in advance of the hearing. As to the first of these contentions, suffice it to say that we have examined the hearing transcript in its entirety and find counsel’s performance to have been fully adequate to protect his client’s interests.
As to point two, a detention hearing, attended by appellant’s mother, was held in the Juvenile Court on September 3, I960. At the conclusion of that hearing, the judge set September 11 for the certification hearing. We conclude that these events constituted more than sufficient notice to appellant’s parents under any test and therefore need not decide whether such notice is constitutionally mandated by the Supreme Court’s decision in
Re Gault,
Judgment of sentence affirmed.
Notes
The autopsy on the body of the deceased was performed on February 23, 1969 by Dr. Joseph E. Campbell, then Deputy Medical Examiner of Philadelphia. Although Dr. Campbell had died before this case came to trial, the results of his postmortem examination, consisting of slides, photographs, and protocol (the technical term for an autopsy report) were available to his colleague, Dr. Aron-son.
Although the hearing in this case preceded
Coleman v. Alabama,
