I've bought things from both men and women who said it was theirs, only to find out later that one spouse or roommate got mad at the other and decided to take their stuff and sell it. I always get receipts stating they are the owner..just in case.
Fairly cheap beginners drum set, ( around $ 250 new ), depending on what all else they found, cymbals, hi hat, ect.. Definite money to be made in the other items. I agree, some angry better half seeking revenge.
