You know, even though that guy has been caught, even thought the two girls are already dead, There is still one more tragedy to unfold. This guy is a Mexican, right? Let's say he goes to Prison. Inside, He'll most likely join a prison gang, such as the one that M.S. 13 runs inside, or La Familia, doesn't matter. He'll do it so he can stay alive. He'll get used to instituional living (Paid for by taxpayers, such as the parents of the dead girl.) He'll get used to smuggling, and other crimes. When he get's out, and eventually gets deported, He'll be in Mexico for a little while, then come back up.
But this time, he'll have his gang contacts to help him.
Bad scenario, but it happens.
I worked a job where one of the labourers' did exactly that.
After he did his time, he was right back up here...working a 21.25$ an hour job. And trying to sell smack to one of the guys on the job, somebody said something, and he dissappeared.
They know how to work our system, don't doubt it.
