Crime (even inadvertent) doesn't pay
No such thing as 'Finder's keepers' or 'possession is nine-tenths...'
Saw a blurb in the small freebie paper published by The Washington Post, the express.
Apparently originally from AP (Associated Press), under the Crime category:
Find, Keep, Spend
A La Vista, Neb., man was charged with felony theft after he spend $80,000 his bank mistakenly deposited in his account. George J. Costa, 45, is charged with theft of lost or mislaid property. It's a crime to take money given by mistake. More than $106,000 was deposited into his account between August 2006 and February after the bank mixed up account numbers. "'Finder's keepers' and 'possession is nine-tenths of the law' aren't legal principles," said attorney Lee Polikov.
Ooops!
I actually do feel a bit sorry for the guy, though I would hazzard a guess that he probably never bought the matter to the attention of the bank to get things resolved, and he most certainly had to realize that the money wasn't his.
