Motorists traveling southbound on Interstate 25 through Denver were guided off the highway following a death Saturday morning.

A Denver Police Department spokesperson confirmed the fatality occurred sometime around 7 a.m., and involved a person working on their broken-down vehicle. That person was changing a flat tire on the right shoulder just north of the Alameda Avenue exit. They were struck and killed by another vehicle which fled the scene. 

DPD's Sean Towle said police are looking for a black Toyota 4Runner with damage to its right front passenger corner. There is no information about the alleged hit-and-run driver of that 4Runner at this time. 

Neither is any information being released at this time about the deceased.

During the investigation, DPD officers and Colorado State Patrol troopers sent all lanes of southbound I-25 traffic onto westbound 6th Avenue. All southbound lanes were re-opened at approximately 10:25 a.m.

An image from a Colorado Department of Transportation camera at 6th Avenue showed a white tent on the right shoulder of the interstate during the closure. White tents are generally used by detectives to protect crime scene evidence from elements or, in particularly graphic situations, from public view.
