What happened next? I received an envelope in the mail, 2nd day UPS, with a cashier's check to my 17 yr old for 1900 dollars supposedly for a 300 dollar guitar. This phone number was on the UPS label. What did the police tell you. My kid fell for the Craig's list scam and gave out our address before he said anything to us about it. I'm concerned someone is going to come looking for this money?
