A three-vehicle pileup on I-285 in DeKalb County left one man dead Thursday, police said.

Officers with the Dunwoody Police Department were notified of the crash along the westbound lane of the interstate at Ashford Dunwoody Road around midnight. At the scene, police said three vehicles were involved in the wreck.

A 22-year-old man was found lying on the ground, police said. He was taken to Grady Memorial Hospital, where he later died. His name was not released. All others involved in the wreck were not injured or sustained minor injuries, according to police spokesman Sgt. Michael Cheek.

Authorities said that a vehicle was experiencing mechanical issues and stopped on the left shoulder when another vehicle, driven by the 22-year-old, struck the rear of the disabled vehicle. Moments later, a third vehicle struck the second vehicle and then overturned, police said.

With the investigation still active, Cheek said officials have not filed any charges and are still trying to determine the cause of the wreck.
