Kansas City Chiefs linebacker Jovan Belcher committed suicide outside the club's Arrowhead Stadium home minutes after shooting and killing his girlfriend, authorities have confirmed.
Belcher shot his girlfriend, identified by police as 22-year-old Kasandra Perkins, at their Kansas City home before driving to the Chiefs' training facility and turning a gun on himself.
Perkins was taken to hospital with multiple gunshot wounds but was declared dead a short time later.
The couple had a three-month-old child together.
Police confirmed 25-year-old Belcher had been seen in conversation with Chiefs general manager Scott Pioli and coach Romeo Crennel in the moments before he shot himself, during which time he reportedly thanked them for their support during his career.
Kansas City Police Department spokesman Darin Snapp confirmed details of the apparent murder-suicide in a video posted on the Kansas City Star website.
"A little before 8am this morning we got a call to a residence on Crysler (Avenue) with regard to a shooting," Snapp confirmed. "When officers arrived, a lady came out to say that her daughter had been shot multiple times by her boyfriend, and she identified him as Belcher, being a Chiefs player.
"At around 8.10am we received a call from the Arrowhead security stating that there was an individual - they identified him as Belcher - with a gun to his head standing in the parking lot.
"When we arrived, officers were getting out of the car and observed Scott Pioli and also coach Romeo Crennel and another individual were outside talking to Belcher.
"When the officers approached and tried to get into the conversation, that's when Belcher turned around, walked approximately 30 feet in the opposite direction of everybody, and shot himself."
