Missing Sierra College student Sean Patrick Sullivan, 21, was found dead at 11:30 a.m. Monday.

Sullivan was last seen on Sept. 19 between 4:07 and 4:19 a.m. near La Riviera Drive and Howe Avenue.

A CalTrans worker picking up garbage located Sullivan’s car, a black 1993 Z-28 Chevy Camaro, and his body at the Eastbound I-80 Greenback Lane exit.

The cause of death was related to a traffic accident, said CHP spokesman Max Hartley, who added that no foul play was suspected.
