(AP) — Authorities are searching for a pickup and stock trailer involved in a fatal crash on Interstate 80 in south-central Nebraska.

The crash occurred around 5:20 p.m. Saturday about four miles east of the Elm Creek interchange.

The Nebraska State Patrol says 29-year-old Juan Rivas, of Grand Island, died after being ejected from a pickup that had gone onto the median and rolled. Two other men in the truck were hospitalized.

The patrol says the pickup driver had swerved onto the median to avoid the other truck and trailer as they changed lanes. Witnesses say the pickup hit the left rear side of the trailer before leaving the roadway.

The truck and trailer didn’t stop after the accident. It’s unclear whether the truck driver knew there had been an accident.
