GRETNA, Neb. (AP) — The driver of a cement-mixing truck has died in a two-vehicle crash in Gretna, officials there said.

The crash happened around 11:15 a.m. Thursday at the intersection of Highway 370 and Wickersham Boulevard, according to a news release by the Sarpy County Sheriff’s Office.

Investigators say a car driven by an 18-year-old Murdock man turned left in front of the cement truck, which hit the car. The crash sent the truck into a ditch, where it overturned. The driver of the car and his 68-year-old grandmother, who was his passenger, were taken to a hospital for treatment of injuries.

The driver of the truck, 58-year-old Gregory Brennan of Omaha, died at the scene, the sheriff’s office said. The crash remains under investigation.
