Jovan Belcher, 25: December 1, 2012 (Photo: Jamie Squire, Getty Images) Kansas City Chiefs linebacker Jovan Belcher sent a text message saying he "would shoot" his girlfriend less than two months before murdering Kasandra Perkins and then killing himself, case documents obtained by USA TODAY Sports reveal. GUN CULTURE: Three out of four NFL players own gun Prosecutors in Jackson County, Mo., closed the case Friday. According to the final report, Belcher fatally shot Perkins, 22, his longtime girlfriend, with a .40-caliber handgun before committing suicide at the Chiefs' training facility with a different weapon. A bullet hole in the floor of the master bathroom that went through to the basement in the couple's Crysler Avenue home suggests Perkins was on the floor when Belcher fired that shot. The report notes 10 apparent gunshot wounds on the front of Perkins' body, and police found eight spent shell casings and three bullet fragments in the bathroom. Another spent bullet was found in the basement. Cheryl Shepherd, Belcher's mother, told police she heard a "thump" before the gunshots. She had recently moved in with the couple – who were parents to an infant daughter, Zoey – because they were having "relationship problems due to financial issues associated with Perkins' spending habits." Shepherd told police that Belcher and Perkins argued that morning about going out "to a club or partying." Belcher's actions that morning came less than two months after he sent a text message to another girlfriend suggesting he would harm Perkins. He told his second girlfriend that he "would shoot" Perkins "if she didn't leave them alone." According to the case file, the second girlfriend thought he was joking. Before their deaths, the couple was receiving help from the Chiefs organization, the Star previously reported. Head coach Romeo Crennel told police that Belcher, 25, missed a team meeting a few weeks earlier because he said Perkins had not come home the night before, leaving him to watch the baby.

Belcher told his other girlfriend that Perkins "knew exactly how to press his buttons and make him angry" and that she had "threatened to take all his money and his child if they split up." Not contained in the case file – 62 pages of evidence, witness interviews and police observations – are the toxicology results and crime scene diagrams. The Kansas City Star first reported the release of the case documents. Contributing: Steve Wieberg in Kansas City, Mo. Story Highlights
