This appeal arises from the conviction of the defendant for the attempted murder of his wife.
The defendant was indicted on September 11, 1979, by the Rockingham County Grand Jury and charged with the attempted first-degree murder of his wife, Karen Baker. On October 25, 1979, the defendant entered a plea of not guilty by reason of insanity and waived his right to a bifurcated trial.
At trial, the defense called two psychiatrists, Dr. Payson and Dr. O’Brien, who testified that the defendant was, in their opinion, legally insane at the time of the crime. The State then called Dr. Strauss, an expert on domestic violence, to testify on the subject of *775 battered wives. Both the defendant’s wife and his daughter had testified previously that the defendant had physically abused them on numerous occasions. Dr. Strauss testified that husbands who beat their wives had themselves often been subjected to or had observed physical violence as children in their own homes. He further testified that current research does not indicate that mental illness is an important cause of wife-beating. Dr. Payson likewise concluded on cross-examination that wife-beating is not necessarily caused by or reflective of mental illness. In response to a hypothetical question, Dr. Strauss stated that, in his opinion, a marriage such as the defendant’s would probably fall within the contours of the “battered wife syndrome”, and Dr. O’Brien arrived at the same conclusion on cross-examination.
The Trial Court {Bean, J.) overruled the defendant’s objections to this entire line of questioning. The jury found the defendant guilty as charged, and the defendant appealed.
The defendant first argues that the testimony of Dr. Strauss on the subject of battered wives was only marginally relevant but was highly prejudicial and obscured the “real issue” of the defendant’s insanity and therefore its admission constituted an abuse of discretion. We disagree.
Whether opinion testimony will be of assistance to the trier of fact and admitted is a matter within the broad discretion of the trial judge.
State v. Staples,
The testimony regarding the battered wife syndrome was offered to rebut the defendant’s evidence on the issue of insanity by providing an alternative explanation for the defendant’s assault, on his wife. The State essentially contends that the attempted murder was but a single episode in a recurring pattern of domestic violence and was neither caused nor produced by mental illness or
*776
insanity. We note that many courts, in a similar context, have held that testimony concerning the “battered child syndrome” is admissible to show that an injury to the child was not accidental but rather was consistent with a pattern of physical abuse.
State v. Wilkerson,
Nor do we see how the admission of this testimony unduly prejudiced the defendant. It was not the type of evidence from which “the jury could have derived no benefit . . . but could only have been confused or misled. . . .”
Perkins v. Company, supra
at 214,
The defendant next argues that the trial court erred in permitting the State’s expert witness to testify in rebuttal and that the use of the hypothetical question posed to this witness was improper because the question assumed facts not in evidence. Both of these contentions are without merit. Because insanity is an affirmative defense,
Novosel v. Helgemoe,
The defendant next contends that he should have been allowed to make his closing argument after the State closed and that the trial court’s denial of his request to this effect resulted in
*777
substantial injustice to him. This argument overlooks the fact that the order of closing arguments is committed to the trial court’s discretion and “[t]he court’s exercise of this discretion will not be set aside except for manifest abuse.”
State v. Garceau,
The defendant’s final argument relates to the burden of proof he must bear with respect to his insanity defense. In
Novosel v. Helgemoe,
The State, of course, had the burden of proving beyond a reasonable doubt that the defendant “purposely” committed the crime with which he is charged. RSA 629:1 I; RSA 630:1-a;
Sandstrom v. Montana,
Although in this case the court did not expressly instruct the jury as to the order in which it was to consider criminal guilt and criminal responsibility, we conclude that the content and sequence of the instructions made it sufficiently clear that the jury was not to address the issue of insanity until it had first determined that the State had proved all the necessary elements of its case beyond a reasonable doubt. To avoid any problems in the future, we suggest that trial judges expressly charge the jury as to the proper order of its deliberations. With this in mind, we reiterate that the “apportionment of the burden of proof [under Novosel] violates no constitutional guarantee.”
State v. Rullo,
Although it is not essential to our holding, we note that the defendant waived the bifurcated trial to which he was, upon request, entitled.
Novosel v. Helgemoe, supra
at 124-25,
Exceptions overruled; affirmed.
