They may not have enough to pin him for the murder but he will do time for being there and knowing what went down!
Without the weapon and his prints on it, they could come stuck in pining the murder on just him when there was 3 of them there. Unless somebody snitches of course!
Please stop. Please.
This isn't a movie. This isn't a television show. This is not something you watch with popcorn. It's real life. There's not a jury in the world that's not going to convict this guy with the evidence the prosecution has.
No murder weapon, no case is something that happened in the 1980's. please cut it out.
