(AP) -- Authorities have completed their investigation into the deaths of Kansas City Chiefs linebacker Jovan Belcher and his 22-year-old girlfriend, formally ruling them a murder-suicide.

The Kansas City Star (http://bit.ly/V57Kip) reported Tuesday that Jackson County prosecutors closed the case Friday.

Newly released police reports show Belcher sent a text message to a girlfriend several weeks before he killed Kasandra Perkins on Dec. 1.

Afterward, he drove to the team's practice site and committed suicide in front of his coach and general manager.

In the text, he wrote he "would shoot" Perkins "if she didn't leave him alone." Belcher and Perkins were the parents of a 3-month-old daughter.

Belcher also told his girlfriend that Perkins had "threatened to take all his money and his child if they split up."
