There were no details given about how his personal property - it happened to be a gun - was STOLEN. As long as it was on his property - probably was, as it was his personal firearm according to he story - the only responsibility he had was to ensure that a minor had no access to it if it was in a condition that it could be discharged (loaded, not locked, etc). Nothing in this story suggests that a minor was involved.
In fact, now that Mr. repeat offender here is being charged with a couple of felonies, maybe he'll be off the street for a while.
So, given your logic, if someone breaks into your house, steals your keys and your car, and mows someone down with it, you are responsible for that?
It was stolen from him (assuming it was a male deputy), and he reported the theft. Hopefully he'll get his property back.
