MADISON -

The medical examiner has identified the pedestrian who was hit and killed early Monday morning on the Beltline.

Madison police are investigating the crash that took place in the eastbound lanes of Highway 12/18 near Gammon Road. The eastbound lanes were closed for about four hours while officers investigated the crash.

Dane County Medical Examiner Director of Operations Barry Irmen said Tuesday that 26-year-old Dustin D. Dilks, of Madison, was pronounced dead at the scene of the crash Monday.

Police said a driver hit Dilks around 2:15 a.m. The driver told police he saw Dilks standing in the middle of the far right lane moments before the crash.

"It appears that this individual was in the roadway and put his hand up as a car was approaching, and unfortunately for that motorist, he was unable to stop," Madison police spokesman Joel DeSpain said.

Investigators said they don't know how Dilks got onto the Beltline or why he was walking on the highway.

"He could have been walking along the Beltline. He could have left a vehicle somewhere and was a stranded motorist. At this point we really don't have those answers yet," DeSpain said.

Investigators did not find a stranded car in the area. Witnesses said Dilks was hit multiple times by other vehicles. Investigators are working to track Dilks's whereabouts before the crash to learn more information.

All lanes of the Beltline reopened just after 6:45 a.m.

Police said speed and alcohol were not factors in the crash.
