Authorities Wednesday identified a motorcyclist who died after a four-vehicle accident in Sarpy County.

The accident occurred at 4:35 p.m. Tuesday on the southbound lanes of U.S. Highway 75, a few hundred yards south of U.S. Highway 34.

The Sarpy County Sheriff's Office says the motorcycle hit a minivan, which triggered a secondary accident between a work van and a pickup truck that were trailing the motorcycle and minivan.     

The sheriff's office says the motorcyclist died at the scene. The driver was identified as 47-year-old Jody A. Emmert, of Bellevue. 

The driver and passengers in the pickup - which included children ages two, 13 and 16 -  were taken to a hospital for treatment of non-life-threatening injuries. The work van and minivan drivers were taken to a hospital as precautions.     

Authorities said the crash is still under investigation.
