Kansas City Chief's line backer Jovan Belcher killed his girlfriend before driving to the team's facility and turning the gun on himself as team officials were confronting him, police officials said.

Police spokesman Darin Snapp said authorities received a call Saturday morning from a woman who said her daughter had been shot multiple times at a residence about five miles away from the Arrowhead complex. Snapp said a call was then received from the Chiefs' practice facility.

Upon arriving, Snapp said that police witnessed a black male in a car with a handgun to his head talking to two Chiefs officials. That's when police heard a gunshot.

Arrowhead Stadium has been lockdown since about 8 a.m.

"We can confirm that there was an incident at Arrowhead earlier this morning," the Chiefs said in a statement. "We are cooperating with authorities in their investigation."

The season has been a massive disappointment for the Chiefs, who were expected to contend for the AFC West title.

But they're just 1-10 and mired in an eight-game losing streak that has been marked by devastating injuries and fan upheaval, with constant calls the past few weeks for general manager Scott Pioli and coach Romeo Crennel to be fired.

Kansas City is scheduled to host the Carolina Panthers on Sunday.

The Chiefs have been ravaged by injuries, led the league in turnovers, can't settle on a quarterback and are dealing with a full-fledged fan rebellion. The Twitter account for a fan group known as "Save Our Chiefs" recently surpassed 80,000 followers, about 17,000 more than the announced crowd at a recent game.

Things have been so bad this season that Crennel fired himself as defensive coordinator.
