He must have roided up hard to overcompensate for that twink beating the shit out of him before he stabbed him.
The twink was 6’5” with fight training and was a dealer who owed Kenny a few Bob.
The cop he stabbed up was left on his own by his teammate when the dog started barking. They were wearing camouflage gear casing the house for a big stash of cash. How did he walk away from that one, eh?
