it just seems like the ppl that were harder to catch or didnt get caught just did it by themselves, werent connected to the victim thru witnesses or anything, and didnt tell anybody.
the assholes that are getting caught up are doing stupid shit like murdering someone after having a brawl in a house party with 20 ppl there and sayin shit like "youre going to get yours tonight!" stupid fucking assholes. obvious connection obvious motive for murder. every person who is involved is another person who will potentially be interviewed and tell the whole thing.
