Detectives are investigating a west Phoenix fatal collision Tuesday night when a pedestrian was hit twice by the same vehicle, police said.

At about 7:15 p.m. Oct. 3, officers found a man with serious injuries near 43^rd and Glendale avenues.

He was treated at the scene by Phoenix firefighters but did not survive, authorities said.

Preliminary information indicates the man was crossing 43^rd Avenue, mid-block, when he was struck by a vehicle traveling northbound on 43^rd Avenue, according to a release.

“This vehicle was then struck by another vehicle traveling northbound, causing the first vehicle to again strike the man,” the release stated.

Police said impairment is not believed to be a factor in connection with the drivers.

An investigation is continuing.
