31-year-old woman struck and critically injured by hit and run driver while walking in a crosswalk in Alameda County.

A hit-and-run driver struck and critically injured a woman walking in a crosswalk in Hayward on Wednesday evening, a police lieutenant said Thursday.

At about 6:10 p.m., emergency crews responded to a report that a pedestrian had been hit at the intersection of Tahoe Avenue and Hesperian Boulevard, about a block from Mt. Eden High School, a Hayward police said.

Police said that based on the investigation, it appears that the driver of a black sedan heading south on Hesperian struck the victim, a 31-year-old woman, and continued without stopping. There is no traffic light at that intersection.

Police found the suspect vehicle unoccupied in Union City a short time later, according to police. Investigators have not yet identified a suspect in the case.

The woman who was struck remained in critical condition this morning.
