A shotgun-wielding Purdue University grad student killed a dorm supervisor Wednesday who had turned him in on a cocaine charge, then took his own life as police closed in.
The names of the victim, an undergraduate, and his killer were not immediately released.
According to reports, the gunman walked into Wiley Hall, a men's dormitory, and entered the supervisor's room, where he shot the supervisor twice about 2:50 p.m.
The gunman then ran down the hall, locked himself in his room, and shot himself, Purdue spokesman Joe Bennett said.
Police evacuated the building and, after a room-by-room sweep, fired tear gas into the room, burst in and found the body.
University spokeswoman Ellen Rantz said the dorm supervisor had found cocaine in the other student's possession on Tuesday and alerted campus police.
