Opinion by
On Jаnuary 31, 1964, a two story summer cottage, located in Penn Forest Township, Carbon County, burned to the ground. Corporal Komosinsky, of the Pennsylvania State Police, stationed at Hazleton, having been аssigned special duty as assistant deputy fire marshal, Troop N, investigated the fire. (At the time Corporal Komosinsky conducted this investigation, he had held the post of assistant deputy fire marshal for approximately one year, and had handled a total of 35 to 45 investigations.) On the day of the fire, Corporal Komosinsky was on another investigation and was not able to investigate this fire until the following day, February 1, 1964.
Corporal Komosinsky related that he found a mass rubble of charred remains at the building, and that nothing on the premises indicated that the fire was caused deliberately; howevеr, that “I couldn’t find any way where the building could have gone spontaneously and in my investigation I felt it was other than an accidental fire, and I pursued it further.” His investigation was temporarily halted while Corрoral Komosinsky went to Hershey for a one week course of in-service training; however,• upon his return, the minor defendant, Leslie, was in prison, and because his description was similar to the description of a person seen near the area of the fire, Corporal Komosinsky went to the prison to interview the minor defendant. *333 After interviewing Leslie, he obtained a statement from him 1 and, after obtaining this statement, again visited the scene of the fire where he thoroughly examined the debris again for any evidence to indicate that the fire had been deliberately caused, and again failed to find any evidence to еstablish this.
On April 2, 1964, an arson charge was filed against the defendant and a trial was held on January 14th and 15th, 1965. Four witnesses appeared for the Commonwealth: Corporal Komosinsky, Harold Turner, the ownеr of the premises which had been burned, Martin Schoch, and Captolia Sayuk, the latter' two having testified that they saw the defendant going toward the cabin before the fire started; however, only Mr. Sсhoch claims to have seen him returning at about the time of the fire. 2
The only direct evidence of the guilt of the defendant, Leslie, was his confession. The Commonwealth, through Corporal Komоsinsky, attempted to establish the corpus delicti and have the confession properly authenticated and to get it into the record. On the basis of this confession, and the testimony of the аforementioned witnesses, the court below allowed the case to go to the jury, which found the minor defendant guilty.
On January 19, 1965, the minor defendant filed a motion in arrest of judgment and/or a new trial, raising in issue the questions of whether there was sufficient opinion evidence to establish a corpus delicti; whether the confession was voluntary and therefore properly admitted into evidenсe; whether he, the defendant, was properly afforded an opportunity to ob *334 tain counsel; and if lie was advised of Ms rights to remain silent before he confessed. The lower court refused to grant defendant’s motion and sentenced him to a term of 9 to 18 months. Defendant then appealed to the Superior Court, said appeal being heard by six Judges, and they, being equally divided in oрinion, affirmed the order of the court below. We subsequently granted allocatur.
As we said in
Com. v. Nasuti,
“Expert testimony is admissible in all cases, civil and criminal alikе, when it involves explanations and inferences not within the range of ordinary training, knowledge, intelligence and experience. Certainly laymen could hardly be expected to have knоwledge in regard to various types of fires and the difference in the nature, violence and intensity of flames resulting from the burning of inflammable liquids or other materials as contrasted with the burning of a wooden counter or hair upholstery. ... In short, while in some
*335
arson cases the testimony may not need any supplementation by expert opinion, other such cases clearly justify its admission: 2 Wharton’s Criminal Evidence (12th ed.), 341, Sec. 517.”
Com. v. Nasuti,
supra; see also
Pozil v. State,
This does not mean that the Commonwealth is required to primarily and independently establish all elements of the charge, i.e., (1) the occurrence of an injury оr loss—in arson, the burning of a building; (2) the criminality of someone as the source of the injury or loss—in an arson case, that the burning was caused by the willful or malicious conduct of someone, that is to say that the fire in question was of incendiary origin, and (3) the accused’s identity as the person or one of the persons responsible. To view the term corpus delicti in this light, that is, to expect the Commonwealth to establish all three elements independently of a confession, would be absurd. See Wig-more on Evidence, (3d Edition), §2072;
Com. v. Tursa,
Prom a careful review of the record, it is obvious that the Commonwealth failed to do this. Corporal Komosinsky’s examinatiоn of the burned building revealed nothing at all to indicate to him that the fire was of incendiary origin, and his view that the fire was other than a natural fire was based only upon his suspicions. Thus, it is obvious that to estаblish the corpus delicti in the instant case, the Commonwealth relied on the fact that there was a burning, and the confession of the accused defendant, Leslie. This it cannot do. We have recently said, in
Com. v. Burns,
Certainly every alleged criminal has the right to expect and require that all of thе elements of the offense of which he is accused shall be clearly defined by law and established by legal and competent proof prior to his being convicted, and until this is established by the Cоmmonwealth, he should be able to assert his immunity from punishment for any offense with which he be charged and which the Commonwealth has not thus defined and proved. In the instant case, the Commonwealth has failed to sustain its burden as required to establish the corpus delicti of the crime of arson. It will not be necessary for us, therefore, to consider the other allegations by the defendant in this case.
The order of the Superior Court is reversed, and the judgment of sentence of the Court of Quarter Sessions of the Peace of Carbon County at No. 38 April Sessions, 1964, is reversed.
Notes
It should be noted that thе defendant, Leslie, had, on a previous occasion, confessed to crimes, said confessions being proved false after further investigation by the police.
The burned cottage was located approximately 1 mile from where the homes of the two witnesses were located and from which they observed the defendant as he passed by.
