Kansas City Chiefs linebacker Jovan Belcher has killed his girlfriend, then himself.
Police say the two had gotten into an argument early this morning at their home, where he killed her. Belcher then drove to the Chiefs practice facility at Arrowhead Stadium, where team personnel tried to keep him from committing other acts of violence. He shot himself in the head as police were arriving.
Belcher was a University of Maine graduate who went undrafted in 20-09 and signed a free-agent contract with the Chiefs. He became a starting linebacker last year.
