It's stories like these that pretty much explains why good samaritans are hard to come by these days. DCist reports of a woman from Virginia who attempted to return a lost iPhone only to end up geaten beaten.
The 53-year-ild had been shopping at her local 7-Eleven when she spotted an iPhone that had fallen on the floor. She proceded to contact the phone's owners (a man and a woman) and arranged to meet them at a neutral location to make the exchange.
The transaction was completed without a hitch and the couple even gave her a monetary reward. But that was right before they tackled the woman from behind while she was walking away, before throwing her to the ground, kicking her, and reclaiming their cash. Sounds like a pretty brutal scam, although it doesn't explain why they stole back their own cash.
