This is an appeal under the provisions of G. L. c. 278, §§ 33A-33G, from convictions on two indictments charging (1) arson of the Congregation Agu-dath Israel Synagogue in Boston on the morning of May 27, 1970, and (2) breaking and entering the synagogue in the nighttime with intent to commit arson.
The defendant has presented and argued two of his assignments of error. Those assignments not argued are waived.
Commonwealth v. Wilson,
1. Over the defendant’s objections, the trial judge allowed the Commonwealth to elicit an opinion by one Heggarty, a lieutenant assigned to the arson investigating squad of the Boston fire department, to the effect that there were two independent fires in the synagogue, and that they were incendiary in nature. The defendant argues that this testimony was inadmissible because it was based on hearsay; that it was not a proper subject for expert testimony; and that it was not really an opinion at all, but only conjecture.
Heggarty, whose qualifications as an expert are not at issue, testified that he arrived at the synagogue an hour and a quarter after the fire was originally reported, and after the active fire had been brought under control. He made a personal examination of the entire premises lasting three hours, and found positive evidence to indicate that there had been two separate and distinct fires. He was unable to find evidence of accelerants (e.g., gasoline, naphtha, benzine), trailers (lengths of cloth to take a fire from one place to another), or piled rags, newspapers or other debris of a combustible nature. He was also unable to find evidence of a spontaneous or accidental origin for either fire. The basis for his opinion that the fire was set was that there were two simultaneous fires neither of which could be satisfactorily explained otherwise, and “they didn’t start by themselves.” Heggarty testified that he had discussions with District Chief Comfrey, the senior fire department officer
The problem with an expert opinion based upon the hearsay of others is that “[s]uch an opinion would or might well be founded upon facts, the truth of which could not in the nature of things be established to the satisfaction of the jury because no competent evidence respecting them would be before the jury.”
Commonwealth
v.
Russ,
The hearsay contention is based on Heggarty’s testimony that he discussed his investigation and his conclusions with other investigators and firefighters at the scene of the fire and later, particularly with Chief Comfrey, the preceding witness for the Commonwealth. At one point in his testimony Heggarty was led into making some general statements to the effect that his opinion was partly based on his discussions with Chief Comfrey. The record indicates, however, that Heggarty himself observed the facts underlying his conclusions that there were two separate fires and that they were set. Exposure to hearsay, almost inevitable during an investigation, does not necessarily imply reliance thereon.
Clifton
v.
Mangum,
The defendant next contends that the question whether or not the fire was incendiary was not a proper subject for expert testimony, but on the contrary is a subject within the experience of the ordinary juror. “Where jurymen would have no difficulty in forming an opinion for themselves the testimony of an expert witness has no place. . . . On the other hand if a situation is presented on the evidence of such character or complexity that it cannot be assumed to be within the ordinary experience or knowledge of men the testimony of a qualified expert is admissible for such help as it may, if believed, give to the jury.”
Jackson
v.
Anthony,
The opinion of a properly qualified person concerning the cause of a fire is generally admissible in evidence.
Edward Rose Co.
v.
Globe & Rutgers Fire Insurance Co.
The defendant, however, relies on two older cases in which expert testimony concerning fire was excluded. In the first,
Higgins
v.
Dewey,
Of more concern is
Commonwealth
v.
Rodziewicz,
Commonwealth
v.
Rodziewicz
has been cited and argued by litigants, in such cases as
Gechijian
v.
Richmond Insurance Co.
Nor do we feel that the statements elicited from Heg-garty that he did not know the cause of the fire revealed that his opinion was mere conjecture. Read in context, he seems to be saying only that he does not know the specific incendiary agent used. This testimony goes only to the weight to be accorded his opinion, not to its admissibility. Nor do we feel that Heggarty’s opinion should be treated not as an opinion, but as conjecture, because it is based largely on elimination rather than positive evidence of incendiarism. It is not like the conjecture of the fire chief in
Our Supreme Judicial Court has recently stated “that a question which calls for an opinion which is in the domain of the expert’s professional knowledge is not necessarily to be excluded merely because the conclusion of the witness reaches or approaches the ultimate issue before the jury.”
Commonwealth
v.
Montmeny,
2. The second assignment of error argued by the defendant is directed towards the prosecution’s use, while cross-examining the defendant, of a prior inconsistent statement for impeachment purposes. The prior statement, made by the defendant to the police in the dock of the Dorchester District Court just before his arraignment, was an alibi inconsistent with an alibi later used by the defendant in his direct testimony. The trial judge in the Superior Court, after a voir dire, ruled that the prior inconsistent statement, although inadmissible in the prosecution’s case in chief because of lack of compliance with the procedural safeguards required by
Miranda
v.
Arizona,
The defendant attempts to distinguish between
Harris
v.
New York
and the present case on the basis that in the
Harris
case the petitioner made “no claim that the statements made to the police were coerced or involuntary,”
The defendant also argues that the prosecution’s use of the earlier alibi in cross-examination violated an earlier assurance by the Commonwealth that it would not “rely upon or use” the alibi. We agree with the conclusion reached by the trial judge that the Commonwealth’s assurance went only to reliance upon and use of the defendant’s alibi statement in the Commonwealth’s case in chief. We do not agree with the defendant’s argument that because Harris v. New York had not been decided or even argued at the time the prosecution could not have contemplated a distinction between using the statement in its case in chief and using it for impeachment. 2 It seems more probable that the attorneys for the Commonwealth and the defendant were only addressing themselves to the evidence the Commonwealth would introduce in its own case. At that time the defendant’s first alibi was of little or no significance to the Commonwealth’s case; only when the defendant uttered his second alibi at the trial did the first alibi statement become significant. Something more certain than what appears here would be required to convince us that the Commonwealth intended to bargain away its ability to meet the case for the defence as it developed.
Judgment affirmed.
Notes
The doctrine of harmless error appears to have been applied very restrictively
