(KLZA)--Two people were killed in a two-vehicle crash Thursday evening about 8 miles south of Nebraska City.

Emergency crews responded to the crash on U.S. 75 Highway just before 9:00.

According to the Otoe County Sheriff's Office, a preliminary investigation indicates a pickup truck driven by 70-year-old Alvin Sobbing, of Auburn, was southbound when the vehicle crossed the center line and collided head-on with a northbound semi-tractor trailer.

Sobbing and his passenger, a 12-year-old boy, were pronounced dead at the scene.

The semi driver, a 39-year-old Texas man, was not hurt.

The wreck remains under investigation.
