Chiefs running back Jamaal Charles says he's focused on finishing strong after coming back from a devastating knee injury and then dealing with a murder-suicide that hit close to home.

Charles tore his left ACL early last season, but has returned to be one of the few bright spots for the 2-12 Chiefs. He's run for 1,230 yards and four touchdowns this year.

What he's overcome physically pales in comparison to what he's dealt with emotionally.

Three weeks ago Saturday, Chiefs linebacker Jovan Belcher shot to death his girlfriend, Kasandra Perkins, and then drove to Arrowhead Stadium and committed suicide. Perkins was the cousin of Charles' wife, Whitney, and Charles introduced her to Belcher.

Charles declined to talk about the shootings Thursday, saying "I just want to talk about football."
