I concur in the majority’s reasoning and in the result reached in People v Heflin. I also concur in the affirmance of the decision of the trial court in People v Landrum; however, I write separately because I believe that the defendant in People v Landrum, having failed to request an involuntary manslaughter instruction, or to object to the omission of such instruction, is precluded from claiming error by the absence of such instruction. People v Jones, 419 Mich 577, 581; 358 NW2d 837 (1984) (Boyle, J., dissenting). Had the involuntary manslaughter instruction been requested and refused in Landrum, I would agree with both the reasoning and the result of the majority opinion.
