SAN JOSE — The woman charged with killing a Fremont student and injuring a car full of his friends while driving the wrong way on Highway 17 drank eight shots of whiskey and rum before getting behind the wheel, and may have been under the influence of other drugs, according to a new filing submitted by prosecutors.

Ashley Marie Oliver, 28, of San Jose, was charged last month with gross vehicular manslaughter while intoxicated, DUI causing injury and DUI with a blood alcohol level of .08 percent or higher causing injury, in connection with the May 11 crash that took the life of 17-year-old Armando Canales, a junior at Washington High School.

Santa Clara County Deputy District Attorney Heather Melton argued Friday against lowering Oliver’s $450,000 bail. Judge Ronald Toff ruled that Oliver’s bail would stay as it was, and the defendant was taken back to the Santa Clara County Main Jail.

Melton submitted a filing that revealed new details behind the deadly crash, which occurred just after 2 a.m. on May 11 when, according to the California Highway Patrol, Oliver drove her gray Chrysler minivan the wrong way on southbound Highway 17 for two to three miles before hitting head-on a Toyota carrying Canales and four other teens.

Moments earlier, two CHP officers reported that they were southbound approaching Summit Road when they had to swerve out of the way of Oliver’s minivan, and they could see in their rear-view mirrors that Oliver nearly hit at least two other cars as she continued driving against oncoming traffic.

The officers made a U-turn on the highway and started to pursue the wayward minivan, but by the time they caught up to the vehicle near Redwood Estates, the violent crash had occurred, according to the officers’ accounts summarized in Melton’s filing.

Armando was pronounced dead at the scene. The other teenagers in the car, three girls and a boy, were also injured. According to prosecutors, the girls suffered injuries encompassing broken ribs, a bruised lung, perforated bowel, broken feet, broken vertebrae, and a blood clot that might require brain surgery. One girl may require plastic surgery for cuts to her face.

Officers reported that they found Oliver still in the driver’s seat, “incoherent and disoriented,” with dilated pupils, light sensitivity and slurred speech, and emanating “a strong odor of alcohol.”

“Oliver admitted to taking a total of eight shots of hard alcohol — whiskey and rum — before getting behind the wheel to drive that night,” Melton’s filing reads.

The officers also reported that Oliver failed basic sobriety tests, and allegedly tried to “fool” a breath-analysis device by “pretending to expel air into the mouthpiece, but not actually blowing.” When an officer finally retrieved a valid breath sample, the readings reflected blood-alcohol levels of .103 and .102, well above the .08 legal limit. A blood sample drawn about two hours later registered a .09 blood-alcohol level, according to the CHP.

But prosecutors and the CHP suspect that Oliver was under the influence of other drugs in addition to alcohol, possibly benzodiazepenes, but that as of Friday, toxicology results had not come back.

Tina Cacilhas, Armando’s mother, described her son as a “social butterfly” who played football at Washington High and was a student in the fire technology program at Mission Valley Regional Occupational Program. She has also pointed to her son’s death to discourage people from drinking and driving.

Also included in Friday’s court filing were more than two-dozen letters from Armando’s family and friends, including Cacilhas and the victim’s father and brother, pleading with Judge Toff not to lower Oliver’s bail.

“It’s endangering the community, society and putting everyone at risk if she is released on bail,” Cacilhas wrote in her letter. “I don’t want another family, child, and teenager to have to go through what I and the community, family, and friends are going through. My son wasn’t given a chance.”
