KANSAS CITY, Missouri — Kansas City Chiefs linebacker Jovan Belcher was apparently worried he would lose his baby and money to his longtime girlfriend before fatally shooting her and killing himself, according to newly released police reports. Belcher also complained about Kasandra Perkins, the mother of the couple's 3-month-old daughter, in conversations and text messages sent to a woman he was seeing on the side, the reports show. In one text message sent in late October or early November, Belcher wrote he “would shoot” Perkins “if she didn't leave him alone.” The girlfriend told police that Belcher said “his child's mother threatened to take all his money and his child if they split up” and “knew exactly how to press his buttons and make him angry.” Belcher shot Perkins multiple times in their home on Dec. 1 and then drove to team headquarters, where he killed himself in front of his coach and general manager after telling them he “wasn't able to get enough help.” The Jackson County prosecutor's office reviewed the police reports before closing the case Friday. It formally ruled the deaths of Belcher, 25, and Perkins, 22, a murder-suicide, prosecutor's office spokesman Mike Mansur said Tuesday. The night before the killings, Belcher went to a club with the woman he was seeing while Perkins attended a concert with her friends, the reports said. A friend of Perkins has told The Kansas City Star that the couple argued around 1 a.m., about Perkins being out late, although it wasn't clear whether the argument happened in person or on the phone. The police report, which doesn't mention this dispute, said that after Belcher bid his girlfriend goodbye and she went inside her apartment, he fell asleep in his car. About two hours later, police roused Belcher after someone called them to report his idling Bentley as suspicious. The report said Belcher was legally parked and didn't smell of alcohol, but officers asked if he could stay inside the apartment for the night. Belcher tried to call the girlfriend, but she didn't discover the missed calls until the next morning. Two women who were up late invited Belcher to wait inside their apartment. They said Belcher “appeared to be intoxicated” but “seemed to be in good spirits.” — AP
