First degree murder and involuntary manslaughter fall within the same category of unlawful killing, however when the defendant is subject to the misdirection of a jury, the sentence can be one in excess of the prescribed term. In this matter, a man convicted of strangling his wife challenged the trial court decision on grounds of both emotional and mental vulnerability.
In summer of 1974, the appellant married a woman more than half his age, before she travelled back to her home country of Israel. Upon her return, she declared her love for another man with whom she had enjoyed sexual intercourse with on a number of occasions. What then followed was a series of emotional inducements and sexual engagements with the appellant that preceded almost immediate emotional and physical rejections and spurning of his advances.
This pattern of behaviour lasted for a period of around ten days, after which the appellant choked his wife to the point of unconsciousness. Having reported him to the police authorities, the appellant was arrested and charged with assault likely to produce great bodily injury, as per s.245(a)(4) of the California Penal Code, which reads:
“Any person who commits an assault upon the person of another by any means of force likely to produce great bodily injury shall be punished by imprisonment in the state prison for two, three, or four years, or in a county jail for not exceeding one year, or by a fine…or by both the fine and imprisonment.”
Within twenty-four hours of her returning home, the two parties began arguing, whereupon the appellant again strangled his wife, instead using a telephone cord until she was dead. Having confessed, the appellant was charged with first degree murder under ss. 187 and 189 of the California Penal Code which read:
“187(a) Murder is the unlawful killing of a human being, or a fetus, with malice aforethought”
189. All murder which is perpetrated by means of…lying in wait, torture, or by any other kind of willful, deliberate, and premeditated killing…with the intent to inflict death, is murder of the first degree.”
Upon which the appellant appealed on grounds that the jury were misdirected when failing to consider the defence submitted by his instructed psychiatrist of voluntary manslaughter under s.192 of the Penal Code, which states:
“Manslaughter is the unlawful killing of a human being without malice. It is of three kinds: (a) Voluntary – upon a sudden quarrel or heat of passion (b) Involuntary and (c) Vehicular…”
And that due to his mental instability, he was entitled to mitigation under a defence of diminished responsibility as per People v. Mosher, in which malice was eliminated by way of mental defect.
Upon presentation, the California Supreme Court examined s.192 of the California Penal Code and drew reference to People v. Logan, in which the court held that:
“[I]t is left to the jurors to say whether or not the facts and circumstances in evidence are sufficient to lead them to believe that the defendant did, or to create a reasonable doubt in their minds as to whether or not he did, commit his offense under a heat of passion…[F]or the fundamental of the inquiry is whether or not the defendant’s reason was, at the time of his act, so disturbed or obscured by some passion—not necessarily fear and never, of course, the passion for revenge—to such an extent as would render ordinary men of average disposition liable to act rashly or without due deliberation and reflection, and from this passion rather than from judgment.”
While noting that in People v. Valentine, it had been agreed that verbal provocation would be sufficient to constitute arousal of heat or passion.
With regard to the claim of diminished responsibility, it was also agreed that while diminished capacity typically required evidence of mental illness, mental defect or intoxication, it had been recently held in People v. Long, that mental illness or defect without intoxication was equally sufficient as a defence.
Unfortunately for the appellant, there had at no time, been any mention of mental deficiency within his defence, and so while it was held that the jury were incorrectly directed to determine guilt without consideration of s.192, there could be no mitigation for diminished responsibility, therefore only the first element of the appeal was reversed.
