He was also not a big guy, and a foot pound is a foot pound. Even if there was no penetration, getting hit by a medium size pistol round must feel like getting hit by a hammer. Hit him in the nuts or neck, and I bet he slows down a lot, even with body armor.
Don’t forget he was supposed filled with painkillers so the impact of a bullet on body armor would have been unlikely to stop him.
But even a .22lr in the head has a way of getting attention.
Go for the murderers’ weak points !

A friend of mine was a sheriff deputy a few years back and was in excellent physical condition. He responded to a burglary one night and was shot in the chest with a .38 Special from about 10’ away. He was wearing his vest and it saved his life. The 158gr. bullet literally knocked the wind out of him setting him back quite a bit. He said it felt as if he were hit by a sledgehammer. He showed me his chest the next week and there was a deep black & blue bruise mark larger than a softball where the bullet had hit. Even if this loser was pumped up on drugs, a 230gr. 45 round anywhere to the major body mass would have knocked him over and maybe even stopped him in his tracks.
