Here, after reviewing the tendered instruction, we conclude that the court properly rejected defendant s theory of defense instruction on the grounds that it was largely argumentative, did little more than summarize defendant s version of the incident, and was encompassed within the other instructions. Defendant concedes that the revised instruction adequately included the substance of his self-defense theory as set forth in the tendered instruction, but asserts that it failed to include his theory that the shooting was accidental. Our review of defendant s tendered instruction reveals nothing that could be read as asserting that the shooting was accidental. Because the evidence presented supports each theory to some extent, the trial court had an affirmative duty to instruct the jury on both aspects of the defense. However, we conclude that the jury was adequately instructed that defendant could not be convicted of the charged offense if the shooting were accidental.
Voluntary act means an act performed consciously as a result of effort or determination.
Culpable mental state means knowingly . . . . A person acts knowingly with respect to a result of his conduct when he is aware that his conduct is practically certain to cause the result. We conclude that the instructions adequately informed the jury that, to support a conviction for second degree murder, defendant s conduct causing the death of the victim could not have been unintended or accidental. The trial court need not include in the defendant s theory of the case instruction matters that are adequately addressed by other instructions. See People v. Davis , supra .
