I didn't hear him say anything about which gun was the one that fired the shot into Antwun's head? I'll take this as your admission that you don't have an answer. Strange that you come unglued when asked a simple question.
You know that two pistols were used and you heard the DA describe the five execution shots coming from a tiny Kel-Tec 380, the shots that you can see being delivered on the video, and you could see the larger pistol in the video during the initial shooting and Erslands exit from the store, why are you so childishly playing obtuse?
