Knocking on doors and running away is a popular teenage prank — leaving flaming bags of dog poop on the porch is often a second part of it — but it’s typically just an annoyance for the victims. Unfortunately for Florida teen Mark Drewes, some people don’t take being annoyed well. In 2003, Drewes and some friends were conducting a campaign of midnight knocking around their Boca Raton neighborhood when they picked the wrong house. Occupant Jay Levin grabbed a handgun, opened the door and shot Drewes, killing him.
