Appeal is taken from the judgment of sentence imposed following appellant’s conviction of two counts of aggravated assault, criminal conspiracy, and possession of instruments of crime. The sole issue in this appeal is whether the statement taken from appellant prior to trial was obtained in a voluntary manner. We hold that it was and will therefore affirm.
On the evening of September 13, 1976 at approximately 7:30 p. m., complainants Fryson and Mitchell were at their home at 4210 Wyalusing Avenue in Philadelphia. Appellant, accompanied by an unidentified man, rang the doorbell and asked for a “fictitious name.” T.T. 4/26/77, p. 14. When Fryson indicated he did not know the person to whom appellant was referring, appellant produced a sawed-off shotgun and said, “I have one.” id. Fryson pulled a knife and stabbed appellant, who responded with a volley of shots wounding Fryson and Mitchell in the head. As appellant and his confederate fled, Fryson called the police, who accompanied the two victims to Presbyterian Hospital.
A short time later, as Fryson was standing in the hospital trauma ward speaking with the police, appellant entered the room, seeking treatment for his wounds. Fryson immediately pointed him out as his assailant, whereupon appellant was arrested and plaeed in a room in the emergency ward for medical attention. 1 He was visited at 10:15 p. m. by Detective Nespoli of the Philadelphia Police Department, who asked appellant his name, address, and date of birth, id. p. 58. Three and one-half hours later, the detective again visited appellant’s room, read him the required Miranda warnings, and asked appellant if he wished to make a *508 statement. At that time, appellant admitted being at the victims’ residence the previous evening in the company of one Zeke Bonds, but denied having a gun or shooting anyone. Mr. Bonds fired the shotgun, appellant explained, in an attempt to “rip off the guy for his gun.” T.T. 4/26/77, p. 63. Appellant further stated that “when he went with Zeke, he wasn’t going to hurt anyone.” id. A pre-trial motion to suppress the statement was denied and it was admitted at his non-jury trial.
It is an established constitutional principle that a defendant is deprived of due process if his conviction is founded, in whole or in part, upon an involuntary confession. U.S.Const. Amends. V, XIV;
Jackson v. Denno,
“The ultimate test remains that which has been the only clearly established test in Anglo-American courts for 200 years: the test of voluntariness. Is the confession the product of an essentially free and unconstrained choice by its maker? If it is, if he has willed to confess, it may be used against him. If it is not, if his will has been overborne, and his capacity for self-determination critically impaired, the use of his confession offends due process. Rogers v. Richmond,365 U.S. 534 ,81 S.Ct. 735 ,5 L.Ed.2d 760 (1961). The line of distinction is that at which governing self-direction is lost and compulsion, of whatever nature or however infused, propels or helps to propel the confession.” Culombe v. Connecticut,367 U.S. 568 , at 602,81 S.Ct. 1860 , at 1879,6 L.Ed.2d 1037 , at 1057 (1961). See also, Commonwealth v. Walker,470 Pa. 534 ,368 A.2d 1284 (1977).
*509 In determining voluntariness, the court must consider and evaluate the totality of the circumstances attending the confession.
“ . . . [T]he duration, and the methods of interrogation; the conditions of detention, the manifest attitude of the police toward the defendant, the defendant’s physical and psychological state and all other conditions present which may serve to drain ones powers of resistance to suggestion and undermine his self-determination, [citations omitted]
As we have noted, when the question of voluntariness passes beyond the realm of physical coercion and into degrees of psychological coercion, most careful attention will be afforded to any facts, circumstances or events tending to overbear the will of the accused. Commonwealth ex rel. Butler v. Rundle, supra, 429 Pa. [141] at 149, 239 A.2d [426] at 430.”
Commonwealth v. Goodwin,
The burden rests with the Commonwealth to show voluntariness of a confession by a preponderance of credible evidence.
Lego v. Twomey,
*510 At the suppression hearing, the only witness bearing on the confession was Detective Nespoli. The defense offered no testimony. Nespoli summarized appellant’s condition when the statement was taken:
“He was laying on the litter. He told me he was in pain. He said his stomach was hurting, but he answered questions candidly. Everything I asked him seemed to make sense with his answers.” S.T. p. 28. Additionally, Nespoli advised appellant of all required Miranda warnings and asked a doctor, present in the room during the interview, if it would be all right to speak with appellant. The doctor replied yes. Appellant indicated he understood his constitutional prerogatives, that he did not want to continue later and that he would talk at that time. Nespoli further stated appellant did not appear to be in a drugged condition and that no promises or threats of any kind were employed to obtain the statement. Appellant offered no testimony at the suppression hearing to rebut the detective’s assertions.
Appellant argues that the interrogating officer should have made inquiry as to appellant’s medical condition and what medication had been administered to him. In
Commonwealth v. Cornish,
The Supreme Court, has, on a number of occasions, considered the legality of confessions obtained when the accused is suffering from medical infirmities and has found voluntariness based solely on the credible testimony of the
*511
interrogating officer. See, e. g.
Commonwealth v. Cornish,
As the
Moore
court noted, “Here the suppression judge obviously chose to believe the testimony of the two police officers as to [defendant’s] condition and ability at the time the challenged statements were given . . . As we observed in
Commonwealth v. Smith
[
‘An appellate court does not weigh evidence or pass upon the credibility of witnesses, and there is no basis for us to hold as a matter of law that the court’s finding of voluntariness of the confession was not adequately supported and well within the court’s discretion.’ ”
Moore,
supra,
The post-verdict court in the instant case reviewed the notes of the Suppression Hearing, assessed Detective *512 Nespoli’s credibility at trial and found him a credible witness. Based upon this record, we cannot upset that court’s finding that the confession was voluntary and properly admitted.
Judgment of sentence Affirmed.
Notes
. Just prior to being placed in a hospital bed, appellant was escorted to a confrontation with complainant Mitchell. Mitchell identified appellant as his assailant. Mitchell died before trial from causes unrelated to this incident.
. Indeed, the Court in
Cornish
hinted that a preferable procedure would be for the police to first gain an expert medical appraisal of a suspect’s condition before attempting a hospital interrogation, id.,
. This is thus not a case where we must find an “egregious disregard” for appellant’s constitutional rights.
