In a case involving a drug-related murder that occurred in 2007, the trial court committed reversible error by admitting evidence that the defendant was involved in a 1994 homicide in which he broke into an apartment, found his girlfriend in bed with the victim, and shot the victim. The facts of the 1994 shooting were not admissible to show intent or knowledge. The State argued that the 404(b) evidence showed that the defendant knew that the weapon was lethal and intent to kill. Because the victim in this case was killed by a gunshot to the back of his head, the person who committed that act clearly knew it was lethal and intended to kill. The court found that whatever slight relevance the 1994 shooting might have on these issues was outweighed by undue prejudice. Regarding the 404(b) purpose of identity, the court found that the acts were not sufficiently similar. The court discounted similarities noted by the trial court, such as the fact that both crime occurred with a gun.
