Kansas City Chiefs linebacker Jovan Belcher killed himself Saturday morning at the team's facility, moments after killing his girlfriend.

Belcher was 25 years old.

According to Kansas City police, Belcher shot his girlfriend multiple times after the two had been engaged in an argument at home. She was taken to a hospital and pronounced dead.

Minutes after the first shooting, police said Belcher drove to the Chiefs' training facility at Arrowhead Stadium and spoke with team personnel, including head coach Romeo Crennel and general manager Scott Pioli, before taking his own life with a gunshot.

"When officers arrived (at Arrowhead Stadium), they observed a black male who had a gun to his head and he was talking to a couple of coaches out in the parking lot," police spokesman Darrin Snapp told reporters outside Arrowhead Stadium. "As officers pulled up and began to park, that's when they heard the gunshot and it appears the individual took his own life."

A report from the Kansas City Star said Belcher and his girlfriend had a daughter, who was only a few months old.

"The entire Chiefs family is deeply saddened by today's events, and our collective hearts are heavy with sympathy, thoughts and prayers for the families and friends affected by this unthinkable tragedy," said Chiefs owner Clark Hunt in a statement. "We sincerely appreciate the expressions of sympathy and support we have received from so many in the Kansas City and NFL communities, and ask for continued prayers for the loved ones of those impacted."

Belcher was in his fourth year with the Chiefs after signing as an undrafted free agent out of Maine. He started 10 of the 11 games he had played this season, registered 38 tackles.

The Chiefs will play Carolina on Sunday at Arrowhead and the game will go on as scheduled.

"Our thoughts and prayers are with the Chiefs and the families and friends of those who lost their lives in this terrible tragedy," the NFL said in a statement. "We have connected the Chiefs with our national team of professional counselors to support both the team and the families of those affected. We will continue to provide assistance in any way that we can."
