find where you live is first priority.
follow you for 7 days and find your daily schedule
punch a hole in the side of your room while you're away, put a pipe in and attach a canister of C02 to your room
you come home, and sleep
and then if you're still alive in the morning i'll stab you in the chest and inject you with some heroin then drop your body in a deserted area of town making it look like it was a drug gang.
