A woman fatally injured after she was struck by a car as she crossed South 12th Avenue Saturday evening has been identified by Tucson police as 25-year-old Jimena Jimenez.

Jimenez stepped in front of a 2006 BMW sedan about 6:30 p.m. near West Canada Street, police said in a news release Sunday. She was not in a crosswalk.

Jimenez died at a hospital a short time after being struck.

The driver, who was northbound in the median lane, was unable to stop in time to avoid hitting Jimenez, say police. The driver was not impaired and stayed at the scene as police initiated their investigation.

Police have not determined if speed was a factor in the wreck.

The death of Jimenez marks the 25th pedestrian fatally in the city this year, Tucson police said in the release.
