TERRYTOWN, La. – Former NFL football player and Louisiana high school football star Joe McKnight was shot and killed during an apparent road rage incident Thursday afternoon in Terrytown, John Curtis football coach J.T. Curtis confirmed.

McKnight's death was confirmed by Jefferson Parish Sheriff Newell Normand. The suspect in the case was identified as 54-year-old Ronald Gasser, who stayed on the scene and was taken into custody. He was being questioned.

"Our officers arrived on the scene and immediately began administering CPR," said Normand.

"It's horrible," said Curtis, who had McKnight live with him shortly after Hurricane Katrina when he lacked a place to stay. Curtis was heading to the McKnight home to meet with his family.

The incident happened about 3 p.m. near Behrman Highway and Holmes Boulevard, just across the Orleans and Jefferson Parish line.

He played college football at USC, following in the footsteps of Reggie Bush, and had an NFL career with the New York Jets and Kansas City Chiefs before settling into the Canadian Football league after being cut by the Chiefs in 2015.
