people are reading too into the ripped shirt of bobby's. the ripped shirt represents a piece of bobby's soul that was left behind after he killed that kid, thats what i think anyways, and i think i read that in an earlier post. besides the cops would need to test it for any traces of dna and theyd have to find matches and everything, too long and complicated to put in the show. besides it was left behind in canada, it wouldnt be available to the states police, to the canadian authorities its a homeland murder, they have no clue it was a connected mafia murder. but anyways ive run on too long lol i hope ppl get my point.
