PLEASANTON -- A 65-year-old woman who was hit by a car while walking with her husband in a Santa Rita Road crosswalk Saturday night has died from her injuries, police said.

The woman, identified by coroner officials as Yizhen Zhou, of Pleasanton, died Monday evening at Eden Medical Center, where her 72-year-old husband remains hospitalized in serious condition, Sgt. Robert Leong said. Zhou's exact cause of death remains unknown pending an autopsy, and the nature of her husband's injuries were not disclosed.

Leong said that while Zhou's husband remains seriously injured, he is alert and communicative.

"He's kind of in and out, but he's talking," Leong said. "We tried to go see him today, but he was asleep at the time."

The name of the 49-year-old driver who hit the couple as they were walking east in the crosswalk at Santa Rita Road and Francisco Street about 8:30 p.m. has not been released. The driver appears to have been traveling north in the far left lane when she reportedly hit the pair, and Leong said early indicators suggest she never saw them.

"We have not found any evidence that would suggest she tried to stop," Leong said. "That doesn't mean that she didn't try. It's one of those things in which people might do something at the last second and then react, and perhaps that's what happened here. But at this point, it appears that she didn't see them."

The driver is cooperating with police, said Leong, who noted that alcohol and drugs do not appear to be factors.

The crosswalk, which is marked with white paint in a ladder crossing formation, is equipped with two overhead flashing yellow lights in each direction that were working at the time of the accident. While the overhead lights were functional, flashing lights embedded in the crosswalk were not, having been removed from the street Oct. 9, Pleasanton City Attorney Jonathan Lowell said.

According to Lowell, the old lights were removed from the crosswalk so new embedded lights utilizing a hard-wired electrical source could be installed the following Monday. The crash occurred in the time between projects, four days after the old lights' removal and two days before the new lights were put in.

The installation of the new lights was finished Monday, Lowell said.

Anyone with information about the crash is asked to contact Pleasanton police at 925-931-5100. The investigation is ongoing.
