Dude, you can call it a 'finder's fee,' but if he was demanding the money before handing over the purse, the law calls it extortion. Especially if they 'agreed' to the fee along the lines of him saying 'give me a $50 reward or you don't get your purse back.' As it is, there isn't enough info from that poorly written blurb to properly form an opinion either way, other than yes, as I said before, the guy probably didn't deserve to get shot in the head.
