Well to figure this mystery out we need to find out about his father and do background checks. According to me his father used to work for the cartel like the dirty bastard he is. Looks like he sold drugs to and fucked a hooker in front of his coworkers and worked for Osama Bin Laden, Johnny's father seems to be a Neo Nazi too, beat his wife on the regular too.

Johnny is quite the kid at school assaulted his teacher, burned the American flag and dressed up as a KKK member.

With all this information I think that Johnny DID commit the crime, my reasoning being that there is security camera footage, that I dont wanna show. HOWEVER what if the dad did it to and just pinned it on Johnny because he is a shitty father, who fucking know.

With all this information, its the..... DAD!
