Yes, I’m amused at the wild speculation. I particularly like the comment about the punching bag and its having some kind of dark implication.
Perhaps it was a case of mistaken identity/address on the part of the shooters. Here’s my wild speculation: Shooters, or someone they represent, are owed money. Person owing the money gives them false address or they obtain wrong address. Assualt wrong house.
Or maybe he turned in the local drug dealer on the corner.
