Appellant was convicted of homicide by vehicle, driving while under the influence of alcohol, and the summary offense of meeting a vehicle proceeding in the opposite direction as a result of a two-car collision in Somerset County. On this appeal, he alleges several errors by the lower court. For the reasons that follow, we reverse appellant’s conviction for homicide by vehicle, and affirm in all other respects.
On January 19, 1979, at approximately 10:30 p. m., appellant left the home of a friend after consuming eight 12-ounce cans of beer in less than three hours. Shortly thereafter, as he was headed south on Route 280, appellant’s automobile crossed the center line of the highway and crashed head-on into the automobile driven by Herbert L. Ringler. Mr. Ringler was pronounced dead at the scene. Appellant was taken to Somerset Community Hospital for treatment of several facial injuries, where, at police request, he consented to a blood test to determine his blood alcohol content. The test results indicated that appellant’s blood alcohol level was .32. Appellant was later charged with homicide by vehicle, driving while under the influence of alcohol, and meeting a vehicle proceeding in the opposite direction. Following his conviction on all charges, the denial of post-trial motions, and the imposition of sentence, appellant took this appeal.
Appellant contends first that the lower court erred in failing to suppress the results of his blood test. We disagree. The Commonwealth must show by a preponderance of the evidence that the challenged evidence is admissible. Pa.R.Crim.P. 323(h);
Commonwealth v. Brown,
*246
Appellant contends next that the trial judge should have recused himself because he had presided at the suppression hearing. We disagree. Appellant was not prejudiced by the actions of the judge. The evidence adduced at the suppression hearing did not concern the summary offense of which the judge was the sole trier of fact. As to the remaining offenses, the jury was the sole trier of fact.
See Commonwealth v. Pettiford,
265 Pa.Superior Ct. 466, 469,
Appellant contends next that the lower court erred in not granting his demurrer to the charge of driving while under the influence of alcohol. “In ruling on a demurrer, the proper test to be applied by the trial court is whether the Commonwealth’s evidence and all reasonable inferences therefrom is sufficient to support a finding by the trier of fact that the accused is guilty beyond a reasonable doubt.”
Commonwealth v. Wimberly,
Appellant contends finally that the opinion of the lay county coroner was, as a matter of law, insufficient to prove that Mr. Ringler had died as a result of the accident. We agree. Homicide by vehicle is defined in 75 Pa.C.S.A. § 3732 as:
*247 Any person who unintentionally causes the death of another person while engaged in the violation of any law of this Commonwealth or municipal ordinance applying to the operation or use of a vehicle or to the regulation of traffic is guilty of homicide by vehicle, a misdemeanor of the first degree, when the violation is the cause of death.
Our Supreme Court has held that the legislature, in enacting this section, intended to “expand the scope of criminal liability for violations of the Vehicle Code causing death.”
Commonwealth v. Field,
We find that the Commonwealth has failed to prove beyond a reasonable doubt that the victim died as a result of injuries received in the accident or of a chain of events stemming from the accident. The only evidence as to the *248 cause of death was the opinion of the lay county coroner. He testified that he was called to the scene by the investigating officer, and preliminarily “checked as best I could at the scene in the darkness that he died of a fracture of the skull.” (N.T. October 22,1979 at 8). He then stated that he believed the cause of death to be fractures of the skull and neck and crush injuries to the chest. (Id. at 14). He did not give any indication as to how he reached his conclusion except for his preliminary examination on the scene. He did not hold an inquest, nor order an autopsy by a certified' pathologist despite his belief that Mr. Ringler had suffered a “violent or suspicious” death.
If, upon the investigation by the coroner, he shall not be satisfied thereby that the death resulted from natural causes, or by suicide, he shall proceed to conduct an inquest upon a view of the body as provided by law. In the conduct of the inquest, the coroner may require such an autopsy as may be necessary in accordance with law. At the inquest the coroner’s duty shall be to ascertain the cause of death and whether any person other than the deceased was criminally responsible therefor by act or neglect, and, if so, the identity of the person and any further evidence and witnesses regarding the crime.
Act of August 9, 1959, P.L. 323, § 1238, 16 P.S. § 1238. Although an autopsy is not required in every case,
Commonwealth
v.
Haley,
There is no medical testimony in the record before us to overcome the coroner’s failure to order an autopsy or inquest. The coroner testified that generally when the injuries are massive, he does not order an autopsy. Indeed, he testified that he avoided autopsies whenever possible because “most of the time people do not like to have postmortem examinations performed on their loved ones.” (N.T. October 22,1979 at 21). Although the coroner’s concerns are laudable, they in no way affect the burden of the Commonwealth in a criminal homicide trial. The Commonwealth relied on the coroner’s naked assertion to prove the cause of Mr. Ringler’s death. 2 There is no evidence that he gave anything other than a cursory examination at the scene. He did not support his assertion with any physical evidence or description, or the testimony of a trained physician. Further, despite being a layman, he did not order an autopsy or inquest to determine the actual cause of death. The Commonwealth has failed to meet its burden. Regrettably, we must reverse appellant’s conviction for homicide by vehicle. 3
Judgment of sentence for homicide by vehicle reversed and appellant discharged. Judgments of sentence for driving while under the influence of alcohol and meeting a vehicle proceeding in the opposite direction are affirmed.
Notes
. Appellant also contends that he should have been given a breathalyzer instead of a blood test. Although a breathalyzer is usually preferable as the least intrusive means of determining blood alcohol content, “[t]he statute does not require an absolute showing that a breathalyzer was impossible of performance.”
Commonwealth v. Lee,
257 Pa.Superior Ct. 326, 329,
. The Commonwealth contends that expert testimony is not necessary to prove the cause of death when the death is the result of a sudden and traumatic injury.
Furman v. Frankie,
. Because of our disposition of the homicide by vehicle conviction, we need not address appellant’s remaining contentions.
