The late Terrence Kiel, a former Chargers safety, was attending a party at the home of suspended Chargers linebacker Stephen Cooper on the evening of Kiel’s death, according to the San Diego Union-Tribune.

Kiel had just left the party on July 4 when he crashed his car, and was ejected from the vehicle.

Some of the guests tried to stop Kiel from leaving the party because he had been drinking.

Cooper was suspended four games in April for violating the league’s policy against anabolic steroids and related substances.
