LINCOLN, Neb. (AP) — Authorities say a 54-year-old man has died after his car ran into the back of an ambulance on Interstate 80 in southeast Nebraska.

The Nebraska State Patrol identified the victim as Paul Chatfield, of Seward.

The Lincoln Journal Star reports that Chatfield was headed west on the interstate Thursday when his car hit the back of the ambulance, which had slowed for traffic.

Patrol spokeswoman Deb Collins says the ambulance wasn’t hauling a patient and that the ambulance driver and passenger weren’t injured.
