JUST MY OPINION
I feel like I need to jump in here and share my thoughts on this whole gang theory.
First off, I don't know quite how to say this, so I'll just say it... these local gangs (BLP, SSL, BC, CST etc..) are a joke. I mean, seriously. I know, and know of a bunch of these guys and they're really all either stupid young kids, or older people who used to be stupid young kids. Although there have been shootings and stuff like that, stabbing and murdering a girl and leaving her body next to the river, and driving her car up to PC or whatever, is HIGHLY unlikely, in MY opinion.
MS-13, is not in Wenatchee. I know this for a fact. I've heard of a couple Salvadorean kids who claimed to be from MS, and tagged a couple of buildings with it, but that's it. It's pretty well known that young Salvadorean gangster wanna-be's think of MS as a bunch of heroes or something and will "claim" them, even if they really have nothing to do with MS.
If there was any gang involvement, it had to have been a gang from out of town (Tacoma? Spokane? Possibly Los Angeles?). However, I don't see the connection. I respect and enjoy everyone's opinion, and in no way am I trying to start any arguments or trying to be rude. It's just my opinion.
