The State Police say Brett McCullough, 52, of Hot Springs, was killed by a hit-and-run driver while riding a bicycle about 8:47 p.m. Wednesday on Highway 70 West (Airport Road) in Hot Springs.

The report says McCullough was riding eastbound in the outside traffic lane when a vehicle hit the rear of his bicycle. The vehicle fled the scene. McCullough was pronounced dead less than an hour later. Investigators have leads on a potential suspect.

McCullough is the brother of Tippi McCullough, the Little Rock teacher who won a Democratic primary race Tuesday night for election to the state House of Representatives.
