DANVILLE -- A 53-year-old Danville woman hit by a suspected drunken driver on Camino Tassajara last week has died from her injuries, authorities confirmed Thursday.
The victim, identified by the Contra Costa County Coroner's Office as Diana Gregory, was in critical condition for nine days following the Aug. 19 crash, where a car driving eastbound on Camino Tassajara hit her as she was crossing at Tassajara Lane, Danville police Chief Steve Simpkins said. Gregory, who police say was not in a crosswalk when she was hit, was taken to John Muir Medical Center, where she died Wednesday evening.
The driver of the vehicle, 50-year-old Samuel Herrick, posted $50,000 bail at Martinez jail last week after being arrested on suspicion of DUI. While the investigation into the crash is not complete, Simpkins says the woman's death will have an impact on the charges they submit to prosecutors.
"We have a long way to go on the investigation," Simpkins said. "But clearly her sad passing will get reflected in what we present to the DA's office."
Gregory's death comes in the wake of 17-year-old San Ramon Valley High School student Robert Orlando's death after a car he was riding in struck a tree Monday night, on the eve of his senior year. Simpkins says the recent tragedies have the department tied up working two very elaborate cases.
"We are in the midst of two complex investigations, both which have had a sad impact on the community," Simpkins said. "Our hearts go out to all the families involved in both of these tragedies."
Simpkins said the investigation into Gregory's death will take several weeks to complete, as will the investigation into what caused the crash that killed Robert Orlando. Toxicology reports and analysis of skid marks to determine speed are pending in both cases, Simpkins said.
