SOUTH SIOUX CITY, Neb. (AP) — Officials are still trying to identify a man killed in a fiery head-on crash near South Sioux City in Dakota County.

The crash happened late Thursday night on U.S. Highway 20. Investigators say an eastbound semitrailer and westbound car collided head-on, causing both vehicles to burst into flames.

The semi driver escaped and was treated at a Sioux City, Iowa hospital for minor injuries.

The man in the car died at the scene. Officials have said only that they believe the man was from central Iowa.

An autopsy is being conducted and is expected to help identify the victim.
