Seems to me, bankruptcy or not, when you steal a man's car, that's called grand theft auto. Hope they get the bast**d who took it and lock him up for a while.
Check all the local scrapyards, up to 50 miles away. Get info, get names, and tell the scrapyard's that they have to cooperate with law enforcement requests else they will be complicit in the crime.
And I recommend buying a couple things for your home. A good dog that is big, and very protective. Also, several guns, that are also big and very protective. Maybe a security camera pointed at your stuff you don't want stolen in the future.
Also, friends in the Mafia are good to have, pay them the protection money they ask for. It's amazing what, ahem, tips they can track down if one of their "protected" gets robbed. OKAY, I'm just kidding about this last part! There's no Mafia in Oklahoma.
