I was spitballing. I thought he actually somehow removed them from evidence impoundment to sell them, where the serials would have been recorded. But he's a sheriffs office dep. They have no access to that stuff.

What likely transpired was that one of the boys they already had in custody for the murder at RHS coughed up his name to investigators and then they nabbed him with the crime guns as he was getting rid of them.

Dude was already on LE radar and was a major player in the streets.
