WEST BABYLON - The family of an NFL linebacker from Long Island who murdered his girlfriend and then killed himself broke their silence today outside their home.

West Babylon native Jovan Belcher shot Kassandra Perkins, the mother of his 3-month-old daughter on Saturday. Belcher, who was a star Kansas City Chiefs lineman, then drove to Arrowhead Stadium and shot himself. Cops say Belcher did it in front of his head coach, an assistant coach and the general manager.

"The impact that this inconceivable tragedy has had on our hearts is immeasurable,” said Belcher's cousin, Yamiesse Lawrence. “We are overwhelmed with both sadness and confusion."

Belcher and his girlfriend were having problems that got worse after the birth of their daughter Zoey, according to Newsday.

Belcher's mother is caring for Zoey, but the state of Missouri will decide later on permanent custody.
