One of two people hit in a Pleasanton crosswalk on Oct. 12 has died.
"We received word that the female pedestrian succumbed to her injuries last night," Pleasanton police said. "The extent of her injuries and the exact cause of death are not known to the police department at this time."
The Alameda County Coroner's Office confirmed the woman's identity as Yizhen Zhou, 65. The names of the driver and the woman's husband, who was also struck, are not being released by police.
The woman and her husband were crossing Santa Rita Road at a crosswalk at the end of Francisco Street at about 8:37 p.m. last Saturday. Both sustained what police described as "severe injuries."
Pleasanton Police Sgt. Robert Leong said hospital officials described the man in "serious but alert" condition.
The driver, identified as a 49-year-old Danville woman, stopped at the scene and is cooperating with police.
Flashing yellow lights embedded in the Santa Rita Road crosswalk had been removed earlier; yellow warning lights on posts facing traffic in both directions were operating when the couple crossed Santa Rita.
The crosswalk has four overhead flashing yellow lights, two in each direction. The overhead lights are activated when a pedestrian pushes a button at the edge of the road and were working at the time of the accident, according to a statement from Pleasanton City Attorney Jonathan Lowell.
"The embedded lights were removed four days prior to the accident in order to allow for installation of new embedded lights," Lowell said.
"The accident occurred before the new lights were installed," he explained.
Leong said the couple was crossing from the Amador Center shopping center, apparently headed to their home.
The crash closed Santa Rita Road for several hours Saturday night. The Pleasanton Police Department's Special Operations Unit were called out and will be handling the investigation.
The cause of the accident has not been determined.
Anyone with information related to the investigation is asked to contact the Pleasanton Police Department at 931-5100.
