STATE of North Carolina
v.
Calvin Levern MARTIN.
No. 8314SC576.
Court of Appeals of North Carolina.
May 1, 1984.
*806 Atty. Gen. Rufus L. Edmisten by Sp. Deputy Atty. Gen. T. Buie Costen, Raleigh, for the State.
Appellate Defender Adam Stein by Asst. Appellate Defender Malcolm Ray Hunter, Jr., Raleigh, for defendant-appellant.
PHILLIPS, Judge.
Defendant's only contention in regard to his conviction is that he had ineffective assistance of counsel and is therefore entitled to a new trial. This contention is based on counsel's failure to investigate and develop the defense of insanity. In our system of jurisprudence it is fundamental that: Those charged with crime have a right to counsel, which means effective counsel; a lawyer defending one charged with homicide has a duty, subject to the client's approval, to raise any defense that is reasonably supportable, which does not conflict with another defense; and a failure to perform that duty deprives the client of the effective assistance of counsel. In this case, so far as the record reveals, the only defense that was possibly available *807 to defendant was insanity and counsel neither developed nor asserted it. That it was the only defense available to defendant does not mean, however, that counsel was necessarily obligated to develop and assert it. No lawyer has a duty to raise an insupportable defense and no defendant can be prejudiced by such a defense not being raised. The pivotal question, therefore, is whether a supportable insanity defense could have been developed in this case.
A defense of not guilty by reason of insanity is not easy to establish under our law. A showing that a defendant is uncommunicative or suspicious or even cruel and violent is not sufficient. As was stated in State v. Jones, 293 N.C. 413, 425, 238 S.E.2d 482, 490 (1977):
[T]he test of insanity as a defense to a criminal charge is whether the accused, at the time of the alleged act, was laboring under such a defect of reason, from disease or deficiency of the mind, as to be incapable of knowing the nature and quality of the act, or, if he does know this, was, by reason of such defect of reason, incapable of distinguishing between right and wrong in relation to such act.
The burden of showing that this defense could probably have been established by counsel, had he pursued it, reposed on the defendant. McMann v. Richardson, 397 U.S. 759, 90 S.Ct. 1441, 25 L.Ed.2d 763 (1970). And, as has been pointed out, it is a very stringent burden indeed. State v. Vickers, 306 N.C. 90, 291 S.E.2d 599 (1982).
Though defendant strenuously argues that another psychiatrist might have supported an insanity defense, if counsel had had him examined for that purpose, nothing in the record justifies us in so concluding. That he was uncommunicative and suspicious and committed a cruel, heartless and seemingly senseless crime is but background and does not begin to show that he was laboring under a defect of reason that rendered him incapable of knowing the nature and quality of his act. Since the existence of such mental defect is not supported by the record, we necessarily conclude that defendant has failed to show that his counsel was derelict in not pursuing this defense.
But because of errors committed in the sentencing process, defendant must be resentenced. One error was in finding as an aggravating factor that "a lesser sentence will depreciate the seriousness of the crime committed." State v. Chatman, 308 N.C. 169, 301 S.E.2d 71 (1983). Another error was in failing to find as a mitigating factor that defendant voluntarily acknowledged wrongdoing prior to arrest. G.S. 15A-1340.4(a)(2)(l). The State's own uncontradicted evidence was that defendant told the police immediately upon their arrival at the scene: "I shot my wife and then shot myself." Under the circumstances, therefore, the judge was obliged to find this statutorily approved mitigating factor. State v. Graham, 309 N.C. 587, 308 S.E.2d 311 (1983). But the judge's refusal to find as a mitigating factor that the relationship between the defendant and the victim was extenuating, as permitted by G.S. 15A-1340.4(a)(2)(i), was not error. So far as we can tell, the only aspects of defendant's relationship to his victim that could possibly be extenuating were that he was married to her and she had borne him a child. The evidence showed that he had neglected and abused her for years and shot her with no provocation whatever. The statute reads as follows:
i. The defendant acted under strong provocation, or the relationship between the defendant and the victim was otherwise extenuating.
In enacting it, the Legislature apparently had in mind circumstances that morally shift part of the fault for a crime from the criminal to the victim; certainly, it was not their purpose to make homicides of spouses or relatives, however senseless and unprovoked, less deserving of punishment than those of others. Because of the errors discussed, however, defendant is entitled to a new sentencing hearing. State v. Ahearn, 307 N.C. 584, 300 S.E.2d 689 (1983).
*808 The defendant's conviction is affirmed and the matter is remanded for resentencing.
Affirmed and remanded.
ARNOLD and JOHNSON, JJ., concur.
