After Damian McElrath killed his mother, a Georgia jury found him not guilty by reason of insanity on malice murder but guilty but mentally ill on felony murder and aggravated assault. The Supreme Court of Georgia treated the verdicts as legally repugnant, vacated the murder verdicts, and authorized a retrial. The Supreme Court of the United States considered whether the insanity acquittal nevertheless barred a retrial under the Double Jeopardy Clause. It held that a jury verdict acquitting a defendant is an acquittal for federal double-jeopardy purposes even when it conflicts with another verdict. The acquittal reflected the jury’s determination that the prosecution had not established criminal liability for malice murder, and its finality did not depend on consistency with the remaining counts. The Court reversed the Georgia courts’ rejection of McElrath’s double-jeopardy claim and remanded. It left the status of the vacated felony-murder conviction to the Georgia courts as a matter of state law and did not address verdicts rejected by a trial judge before acceptance.
