Wow poor kid. I blame the father 100 %..not the drugs, he chose to do the drugs so he is to blame. PCP is a crrrrrrrazy drug...freaking crazy. You become SUPER strong, and dont feel any pain you also get really hot ( thats why ppl on PCP get naked because it raises their body temperature). Belive me when someone is naked and sweaty and crazy strong its really really hard for cops to get a hold of them. They are slippery and theres nothing to hold on to!
Anywho I feel for the kid, no amount of prison time or death even will ever do justice for that boy, hes gonna have to be haunted with that for the rest of his life.
