A Keizer man was killed Thursday morning after he was hit by a vehicle while crossing Interstate 5 on foot.

Oregon State Police report a 2000 GMC Yukon driving southbound struck the victim near mile marker 259 at about 5:44 a.m. Thursday. Officials believe the pedestrian was crossing the freeway from west to east on foot. Several other vehicles reported running over the pedestrian after the first crash.

The pedestrian, identified as Dale Allen Underwood, 44, of Keizer, was pronounced dead at the scene.

Southbound lanes of Interstate 5 were shut down for three hours as investigators were on scene. Officers are still trying to figure out why he was in the area, and would like to speak with anyone who had contact with Underwood in the hours prior to the incident.

Anyone with information on the case is asked to call Trooper Joseph Skipper at 503-378-3387 ext. 32000.
