Authorities have identified the man who was killed in a four-vehicle crash last week on a highway in western Hennepin County.

Cody A. Olson, 23, of Waconia, Minn., died in the pileup last Monday evening on Hwy. 55 at Mohawk Drive in Medina, the medical examiner's office said.

Three other people among the seven in the passenger vehicles were treated at North Memorial Medical Center in Robbinsdale for their injuries.

The Sheriff's Office has yet to name any of those injured or reveal their conditions.

The crash closed the highway for several hours as authorities investigated the incident. No information has been released about the circumstances of the wreck.
