Case Summary
People v. Grandberry, decided by California Court of Appeal on December 8, 2025, resulted in a defendant win outcome. The defendant, Grandberry, was convicted of second-degree murder and assault with a deadly weapon. The appellate court affirmed the conviction, rejecting Grandberry's arguments that the trial court erred by admitting evidence of his prior convictions and by failing to instruct the jury on voluntary manslaughter. The court found the prior conviction evidence was admissible for impeachment purposes and that the evidence did not support a voluntary manslaughter instruction. The court held: The trial court did not err in admitting evidence of the defendant's prior convictions for impeachment purposes, as the probative value of the evidence outweighed its prejudicial effect, and the convictions were not too remote in time.. The trial court did not err in refusing to instruct the jury on voluntary manslaughter because the evidence presented did not support a finding that the defendant acted under a sudden quarrel or heat of passion.. The appellate court found that the defendant's prior convictions were admissible under Evidence Code section 352 because they were relevant to the defendant's credibility and the trial court properly balanced the probative value against the potential for prejudice.. The appellate court determined that the evidence presented at trial did not demonstrate sufficient provocation to warrant a voluntary manslaughter instruction, as the defendant's own testimony indicated a cooling-off period.. The conviction for second-degree murder and assault with a deadly weapon was affirmed based on the sufficiency of the evidence presented at trial.. This case reinforces the established standards for admitting prior convictions for impeachment and the requirements for instructing juries on lesser included offenses like voluntary manslaughter. It clarifies that defendants must present evidence supporting provocation to warrant such instructions, and trial courts have discretion in balancing the prejudice of prior convictions against their probative value.
