Pleasanton deadly crash: Speed may have played role in car accident that killed family of 4 on Foothill Road, police say [Video]

PLEASANTON, Calif. (KGO) — Pleasanton police said speed may have been a factor in a crash on Foothill Road near Stoneridge Drive on Wednesday that killed a family of four.

The victims were a Pleasanton family of two adults and two children under the age of 15.

Police continue to investigate a single-vehicle accident that occurred around 9 p.m.

The coroner’s office is still working to notify the next of kin, so the family’s identity has not yet been confirmed.

A full investigation of the accident is ongoing, although police say speed may have been a factor. The car appears to have lost control and collided with a large oak tree, killing all four family members inside.
