Colorado State Patrol says the man was hit by a second vehicle, but that driver did not stay at the scene. They say charges are not expected for that driver, but they would also like to talk to that driver.

Southbound lanes of I-25 were closed for about four hours, causing long delays for drivers.

The victim’s identity has not been released.
