really not too hard to figure out
it was very obvious Nicholas was into some bad stuff, I mean how many 13 year olds do you know who has multiple tattoos and stays out that late at night. And its very much probable the older brother Jason knew about it.
My guess is he was hanging out with the wrong crowd, like much older kids, maybe dealing some drugs, and things gone bad maybe with a local or even transient biker gang, and Nicholas was taken, probably kidnapped at first but then killed off somewhere across the border. Just feel sad for the family because eventually his body will turn up.
I'm suspecting the cops knows this too, they know this is what happened to Nicholas thats why they never took too much time and impetus to investigate it.
