Quoted from jackd104:happen to be hanging with an attorney buddy. He says the dude needs to work it out with his old lady, whether with the cops or court or whatever. You were a good,faith purchaser - he has no right to take it back from you. If you want to be a swell guy sell it back to him with some extra for your trouble.
Yep.BFP for value. bona fide purchaser for value. No reason to suspect any issue. Should be clear. Let him take you to small claims .
