PHOENIX (AP) -- A 31-year-old woman is dead following a hit-and-run collision in north Phoenix.
Sgt. Tommy Thompson says Jennifer Lynn Millerbis died following Saturday's crash.
He says little is known about the crash but authorities suspect that she was struck by a white sedan along North 51st Avenue near Indian School Road about 2:30 a.m. The car fled the scene.
The woman was left lying in the roadway and was accidentally run over a short while later by a semi tractor.
He says that the truck driver stayed at the scene and was evaluated, but did not appear to be impaired.
Thompson says police are hoping anyone with information on the suspect car or driver will contact them.
