Gotta' remember, people in prison can't exactly arrange things in the open, so it will take time.
Providing you’re stupid enough to trust the guys in prison to keep quiet. Remember the guy that hired a prisoner to kill the thug who murdered his parents? His hiree filled a light bulb in the perps cell with gasoline killing the thug. Problem was that after he got caught he sang like a bird, and now mom and dad are still dead, but jr is serving life in prison for conspiracy to commit murder. Does that honestly sound like a good deal to you?
BTW, if anyone can remember the guy’s name or the state, please jog my memory.
