(AP) — Authorities say at least two people have been fatally injured and three others hurt in a collision between an ambulance and a pickup in eastern Nebraska.

The accident occurred around 10:30 p.m. Tuesday on U.S. Highway 34 near Elmwood.

Cass County Sheriff William Brueggemann (BROO’-geh-muhn) says deputies had been trying to find the pickup because of a report about an erratic driver. He says the pickup crossed into oncoming traffic and struck the ambulance. The Weeping Water ambulance was taking a patient to a Lincoln hospital.

Officials say the pickup driver died at the scene and that the ambulance driver died at a Lincoln hospital. Three others in the ambulance, including the patient, were taken to hospitals.

The names of those involved haven’t been released.
