What crap.
I carry - but not my whole damn armory. If they ever find me dead by the side of the road there will only be one weapon "near" me - and I hope to hell it'll be empty with an empty magazine beside it.
For the weapons not to be stolen in the first place is suspicious. That means he was shot for something other than theft - and even then I can't see the shooter(s) leaving the guns.
For the guns to be found, they were meant to be found.
The ballistics report on this one would be very interesting.
