Amber D. Stanley, a Prince George’s County honors student, started her senior year this week with aspirations of going on to Harvard. Wednesday night a gunman kicked in the front door of her house, climbed the stairs and shot her several times in bed.

Police think the gunman set out to kill someone specific, walking straight to Amber’s bedroom, shooting and then fleeing without taking anything. But they don’t know whether he intended to kill Amber, or whether he got the wrong bedroom or even the wrong house.
