Jeser Cisneros-Hernandez, 22, has been charged with vehicular homicide in connection with a crash that killed four Iowa motorcyclists.
According to authorities, the Kansas man was driving his car on Highway 26 in Western Nebraska when he crossed the center line and struck the two motorcycles each carrying two people.
Shelia Matheny, 54, and James Matheny, 61, of Bedford were riding on one. The riders on the other motorcycle were 59-year-old Jerolyn Weese and 58-year-old Michael Weese of Council Bluffs.
Cisneros-Hernandez was driving from Sidney, Montana to Kansas and told investigators he'd gotten very little sleep the night before.
