A two-vehicle fatal collision on the border of Menlo Park and Palo Alto on Thursday morning, Nov. 20, left a 77-year-old woman dead and blocked both eastbound lanes of Sand Hill Road for more than three hours, authorities said.
Two cars, a Kia and an Audi, collided shortly after 9:30 a.m. in the area of Sand Hill Road and Saga Lane, said Sgt. Sharon Kaufman of the Menlo Park Police Department.
A passenger in that car, Victoria Ubaldo of San Jose, was pronounced dead at the scene, said Sgt. Kaufman.
The driver was Ms. Ubaldo's 27-year-old granddaughter, said Sgt. Kaufman. Also in the car was the driver's 2-year-old daughter. Neither was seriously injured, Sgt. Kaufman said.
The sole occupant of the other car was also not seriously injured, Jackson said.
Multiple agencies responded, including the Menlo Park police and the Menlo Park Fire Protection District, and the Palo Alto Fire Department, Palo Alto fire Battalion Chief Chris Jackson said.
The collision sent the Kia into the driveway of the SLAC National Accelerator Laboratory at 2575 Sand Hill Road, Chief Jackson said.
Both eastbound lanes of Sand Hill Road remained blocked until shortly before 1 p.m., Menlo Park fire Deputy Chief Tim Campbell said.
The cause of the crash remains under investigation. Witnesses of the crash are asked to call Menlo Park officer Ronald Venzon at 330-6300.
