An American football player with the Kansas City Chiefs has shot himself dead after reportedly killing his girlfriend.
Javon Belcher, 25, drove to the team's practice facility near Arrowhead Stadium and turned the gun on himself as two team officials were confronting him.
Police spokesman Darin Snapp said authorities received a call from a woman who said her daughter had been shot multiple times at a home around five miles from the stadium in Kansas City.
The call actually came from Belcher's mother, who referred to the victim as her daughter, leading to some initial confusion, police said.
She said her son and his girlfriend, who has been named as 22-year-old Kasandra M Perkins, had been arguing recently. The couple had a three-month-old baby.
Mr Snapp said when police arrived at the practice facility they saw a black male in a car with a handgun to his head talking to two Chiefs officials.
He said the linebacker - who was in his fourth season with the American football franchise - thanked general manager Scott Pioli and head coach Romeo Crennel for all they had done for him, before shooting himself.
He said: "When we arrived (at the house), a lady informed us that her daughter had been shot multiple times by her boyfriend. She identified him as a Chiefs player."
After officers arrived at the training facility, the coaches told them they never felt in danger.
Mr Snapp added: "They were just talking to him and he was thanking them and everything.
"The suspect began to walk in the opposite direction of the coaches and the officers and that's when they heard the gunshot. It appears he took his own life."
Belcher, from West Babylon, New York, played college football at Maine.
"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," Chiefs chairman Clark Hunt said in a statement.
The Chiefs are due to play the Carolina Panthers at Arrowhead on Sunday. The game is expected go ahead as scheduled.
