A 44-year-old Sonoma woman died Thursday afternoon in a collision involving a truck pulling a tractor and a sedan on northbound Highway 121 at Haire Lane near the Sonoma County line, according to the California Highway Patrol.

The collision was reported around 1 p.m. The Napa County coroner's office was summoned to the collision scene and later identified the woman as Debra Dell Zygielbaum.

Zygielbaum was a well-known figure in the Napa Ag community. She was the former vineyard manager for Robert Sinskey Vineyards and was a member of the board of directors at the Napa County Farm Bureau.

"This is a painful and heartbreaking loss for our entire organization, Debby's family and friends, as well as our entire community," the Farm Bureau said in a statement Friday.

"Debby was a vibrant member of the Board of Directors and actively involved in many aspects of the Napa County Farm Bureau. She led the Napa Organic Group which focused on sustainable farming practices and was actively involved in the Farm Bureau's political and community education endeavors."

The CHP said a truck driven by Luis Castillo-Reyes, 34, of Santa Rosa was southbound when it crossed into the northbound sedan's path, causing a head-on collision.

The sedan driver was pronounced dead at the scene.
