A teenager introduced himself as a neighbor. Asked for donation to a charity which delivers book to a children's hospital to win a trip to Hawaii with his team. Promised to wash windows in return. The donation check was cashed, the teenager never showed up. Turned out that he didn't live at the address he named. The home phone number he left was fake. When called to the named above "charity", no representatives were ever available and the mail box full and not accepting new messages
