Weeks after football player Jovan Belcher committed suicide and killed his girlfriend, more details about the tragedy continue to emerge.

A few months before the incident, the former Kansas City Chiefs linebacker told his mistress that he “would shoot” Kasandra Perkins, the mother of his daughter. A police report obtained by the Kansas City Star states that Belcher texted his secret girlfriend that he would shoot Perkins “if she didn’t leave him alone.”

Cheryl Shepherd, Belcher’s mother, provided the police with information about the events that led up to the Dec.1 murder-suicide, which involved Belcher killing himself in front of Chiefs head coach Romeo Crennel and general manager Scott Pioli. Shepherd said she moved in with the couple a few weeks before the incident. The two were having issues because of "relationship problems due to financial issues associated with Perkins' spending habits."

Right before Belcher took his girlfriend’s life, Shepherd says there was an argument "in regard to one or both of them going out as in to a club or partying."

The police report stated that there were 10 gunshot wounds in the front of Perkins’ body and five in her back. There’s a good chance that she was already on the floor during the time of the shooting, as authorities found a bullet hole in the floor under Perkins’s body. Shepherd also says she heard a thump before the shots rang out.

According to the Star, Belcher was worried that if he and Perkins split up, she would take all his money and their daughter.

Belcher killed himself at Arrowhead Stadium just one day before Kansas City was scheduled to play the Carolina Panthers. The game was not postponed and the Chiefs won their second game of the season.

Crennel was on the sidelines, despite witnessing his player’s suicide. The head coach said he never felt threatened, and Belcher thanked him for everything he had done.

A 911 call made by Belcher’s mom was also released to the public, against Shepherd’s wishes.
