"drinking" buddies? Are you kidding me? These clowns wake up drinking beer and smoking either meth or crack then roll through the mobile home park at all hours of the night. The owner of the home this guy was killed at is a contributing factor by allowing these creeps to stay at his home while he's there or not. While I feel for the deceased and his family, he had no business trespassing nor did his "buddies".
The two guys that were left alive killed the guy. Call it manslaughter or whatever they want. If they weren't high, they'd all be alive today.
