This marks the second time in just over a month that a person has died in medical custody hours after being detained by Pleasanton police in a combative incident.
The situation on Monday began unfolding early in the morning when police received several reports of a reckless driver who struck multiple vehicles in the 5300 block of Case Avenue, according to Silacci. Another report of the driver also hitting a pedestrian was deemed unfounded, Silacci added.
Officers arrived in the area and located the vehicle around 2 a.m., according to Silacci. The driver -- later identified as Johnson -- was initially standing next to her vehicle, but upon seeing police, she quickly got into her vehicle.
"To prevent further property damage and to reduce the likelihood of further injury, officers ordered the subject out of vehicle, but she refused," Silacci said. "Officers then attempted to detain the subject and she physically resisted their efforts to remove her from the vehicle."
The lieutenant said officers ultimately used a control hold to get Johnson out of the vehicle, but as they were detaining her, she started struggling with the officers and made several attempts to grab one officer's gun.
At that point, two officers used their Tasers to subdue the woman and gain control of the situation, according to Silacci. Johnson was detained and placed under a psychiatric hold.
Johnson was then taken to Stanford Health Care-ValleyCare in Pleasanton for a routine medical clearance, Silacci said. At about 7 a.m., a Norcal Ambulance arrived at the hospital to transport her to John George Psychiatric Pavilion in San Leandro for evaluation under the psychiatric detainer.
A half-hour later, on the way to San Leandro, the ambulance was forced to pull over on the freeway interchange in Pleasanton because Johnson was combative in the back, according to Silacci.
Johnson got up from the gurney and jumped out of the ambulance on westbound I-580 just west of the I-680 interchange, according to Officer Tyler Hahn of the California Highway Patrol.
Johnson then turned and ran toward oncoming freeway traffic traveling on the southbound I-680 connector ramp to westbound I-580, Hahn said. Two cars were able to dodge her but a third driver could not avoid her as she jumped in front of his large pickup truck, according to Hahn.
Johnson was struck by the vehicle and died on the freeway, according to Silacci.
The fatality remains under separate investigations by the Pleasanton Police Department, the California Highway Patrol and the Alameda County Coroner's Bureau, according to Silacci. Anyone with information related to the incident can contact Lt. Brandon Stocking at 931-5100 -- reference case No. 18-34368.
Monday's incident comes almost exactly one month after Pleasanton resident Jacob Bauer died at a local hospital after exhibiting respiratory distress in an ambulance on his way for medical evaluation after a combative arrest at the Oak Hills Shopping Center on Sunol Boulevard.
According to police, 38-year-old Bauer was arrested after acting erratically in the Raley's grocery store and then fighting officers who were trying to detain him the afternoon of Aug. 1. Officers used Tasers to control Bauer. That investigation is also ongoing.
