Had a guy who one summer evening left his main door open and just the "locked" screen door to secure the home. Sure! A person got into the house, went into the bedroom where he and his wife were asleep and found his keys in his pants pocket laying on the floor. He stole the pickup out front and took it for a joy ride. I don't remember why but it was abandoned a few miles away. He got his undamaged pickup back later that morning as it was found by LEO.
Didn't learn the first time. The very next NIGHT, I think this time if I remember correctly he didn't secure the front door again. Just closed it. SAME GUY got into his home, stole his keys, and drove away in his pickup. "Victim" heard something and got up and saw the guy driving his pickup away. He pursued the bad guy in another of his vehicles and bad guy got pinned in or stuck by the victim. Bad guy took off running and victim shot him in the back/arse area. Bad guy was caught.
