SARONVILLE, Neb. (AP) — Authorities say a Hastings couple have been killed and two of their children injured in a collision in Clay County.

The 53-year-old man and his 52-year-old wife died in the collision. Their teenage son and daughter in her 20s were flown to a Lincoln hospital. Their names aren’t being released until relatives are notified about the accident.

The truck driver was arrested.
