Kyle Devonte Timmons was convicted of felony murder and related offenses after a confrontation with Dominique Alexander Spears ended in a shooting. At trial, the State introduced Timmons’s Facebook posts as evidence of his violent character after Timmons raised self-defense and evidence about Spears’s conduct. The Supreme Court of Georgia held that the Facebook posts were inadmissible specific-act evidence under Georgia’s character-evidence statutes. A defendant does not open the door to the State’s character evidence merely by raising self-defense, and the statutory exception requires the defendant first to introduce proper evidence of the victim’s pertinent character trait or first-aggressor status. The court nevertheless concluded that the error was harmless under the applicable standard. It also held that the trial court improperly imposed sentences for aggravated assault and aggravated battery after those offenses merged into the felony-murder conviction. The court affirmed the convictions, vacated the challenged sentences, and remanded. Two justices disagreed with the harmless-error analysis.
