A devastating head-on collision on Silverado Trail in Napa County on Saturday, March 28, 2026, resulted in the deaths of three individuals. Authorities suspect the driver responsible for the crash was operating his vehicle while under the influence of drugs or alcohol.

Victims Identified in Fatal Saturday Collision

The Napa County Sheriff’s Office officially identified the three fatalities. They were named as Vivian Bertolino, 65, and Linda Wolters, 62, both residents of American Canyon, and Katrina Clarke, 65, from Sacramento.

The collision occurred on Silverado Trail, situated east of Yountville. According to the California Highway Patrol (CHP), Bertolino and Wolters were traveling together, while Clarke was in a separate vehicle.

Details of the Multi-Vehicle Crash

William Dene Brumley, 68, a resident of Vallejo, is suspected of causing the fatal incident. CHP officials detailed that Brumley was driving a Mitsubishi sedan southbound with Bertolino and Wolters as passengers.

Brumley reportedly crossed into the northbound lane, striking a BMW SUV before colliding head-on with a Toyota sedan. One of Brumley’s passengers died at the scene, and the other passed away later at Queen of the Valley hospital.

Investigators reported that Brumley sustained injuries and was transported to Adventist Health St. Helena hospital, where he was subsequently arrested. The crash location was noted by CHP officials as being near Stag’s Leap Wine Cellars.

Arrests and Ongoing Investigation

Brumley faces charges including vehicular manslaughter while intoxicated and DUI, according to jail records. He is currently being held on $500,000 bail while hospitalized.

As of early Monday afternoon, March 30, prosecutors in the Napa County District Attorney’s Office had not yet filed formal charges. It remains unclear when Brumley will make his initial court appearance.

Injuries to Other Parties

Katrina Clarke, a passenger in the Toyota sedan, was transported to Kaiser Vacaville hospital, where she was later pronounced deceased. The driver of the Toyota, identified Monday as a Sacramento man, along with two other surviving occupants, suffered injuries described as life-threatening by the CHP.

In contrast, two individuals traveling in the BMW SUV sustained only minor injuries and received treatment at the scene. The driver of the BMW was identified as a resident of Reno. The CHP confirmed that the entire collision remains under active investigation.
