I’m going to call this a professional assassination.

It doesn’t fit the profile of an impromptu hit. Clearly premeditated and carried out in cold blood. He had likely been stalking him beforehand.

Things to look for:

If the truck was stolen.
Possibly a drug cartel hit.
Personal association with that Deputy.

Wouldn't a professional know better than shoot a cop in a gas station where cameras would be installed? He didn't park his truck out of camera range.

Supposedly, a suspect is in custody. He was rather sloppy to be a pro.
