Foster v. State, 306 Ga. 587

In 2005 Calvin Foster shot and fatally wounded his estranged wife Daphne; he was arrested at the scene and made statements including “I just shot Daphne” and “I didn’t mean to do it.”
Six cartridge casings were found; autopsy showed multiple gunshot wounds including contact wound to the back; Daphne’s DNA found on Foster’s bloodstained clothes.
Foster raised an insanity defense at his 2009 retrial (after this Court reversed his 2006 convictions for inadequate insanity instructions); he presented expert testimony claiming a transient psychotic episode and inability to distinguish right from wrong.
The State presented rebuttal expert testimony concluding Foster could distinguish right from wrong, plus lay witness testimony that Foster showed no signs of mental illness and did not appear psychotic at arrest.
The jury convicted Foster of malice murder and a firearm offense; trial court sentenced life plus five years and purported to merge felony-murder; Foster appealed, arguing insufficient evidence (insanity/intent) and that jury instructions about punishment were inconsistent/confusing.

Issue	Plaintiff's Argument (Foster)	Defendant's Argument (State)	Held
Sufficiency of the evidence given insanity defense	Dr. Stark’s expert testimony created reasonable doubt that Foster could form malice because he couldn’t distinguish right from wrong	Jury may weigh competing expert and lay testimony and may reject defense experts; State’s evidence supports intent	Evidence sufficient; jury rationally rejected insanity defense and convictions affirmed
Jury instructions concerning punishment vs. insanity-consequence charges	Informing jury of statutory consequences for insanity-related verdicts conflicts with instruction not to consider punishment and is misleading	OCGA §17-7-131(b)(3) mandates these consequence instructions as a limited exception and they supplement—not conflict with—the no-punishment charge	No error; statutory insanity-consequence instructions properly given and do not mislead jury
