The woman was pronounced deceased at the scene by Phoenix fire personnel.

The hit-and-run vehicle is described as a black Ford Focus with front-end damage. There was no description of the driver, according to the Arizona Department of Public Safety.

Phoenix police last reported the car traveling northbound on Interstate 17 at 16th Street, according to DPS.

Police believe that impairment is not suspected.

At this time, it is unclear why the pedestrian was lying on the roadway and if she had been struck by another vehicle prior to the collision, Phoenix police said.
