A traffic pileup early Sunday on Interstate 80 in western Nebraska left five people dead and a Illinois man facing manslaughter charges.
The succession of crashes began about 4:30 a.m. just east of Potter outside Sidney.
Keith Johnson, 27, of Big Lake, Minn., was killed when his semitrailer truck slammed into the back of another semi stopped in a westbound lane of I-80, according to the Nebraska State Patrol.
Vladimir Zhukov, 66, of Oak Park, Ill., had stopped because of mechanical problems, the patrol said. Zhukov was uninjured.
While troopers investigated the crash, traffic backed up and a second fatal crash occurred.
According to Cheyenne County Attorney Paul Schaub, Josef Slezak, 25, of Illinois was driving a semi that crashed into a 2010 Ford Mustang that then struck a 2007 Toyota Corolla. The Toyota was pushed under another truck.
The drivers of the Toyota and Mustang died. Two juvenile passengers also were killed. Schaub did not release the victims' names Monday morning.
Slezak was arrested on suspicion of four counts of manslaughter and one count of careless driving.
The Cheyenne County Sheriff's Office and the State Patrol closed a stretch of I-80 for most of Sunday. Vehicles traveling west were rerouted on U.S. Highway 30.
