DISCOVERY BAY (KRON) — Three children were rescued from a car crash that killed their parents on Highway 4 in Discovery Bay Sunday evening, according to California Highway Patrol officials.

The incident occurred at 11:22 p.m. on state Highway 4 about a mile east of the Old River Bridge, where Contra Costa County becomes San Joaquin County, CHP spokesman Officer Khalid Rashid said.

The accident happened when a car drove into a lane going the wrong direction, authorities said.

A Dodge van carrying six Martinez residents was driving on the two-lane highway’s westbound side when the car hit another vehicle, which veered off to the right and went over the north edge of the roadway and into a creek. The Dodge collided with a Chevrolet pickup truck driven east by a 41-year-old San Pablo man.

The three children and one other adult were rescued from the car and suffered from minor injuries.

For reasons not yet determined, the truck crossed into the opposite lane, Rashid said.

The van swerved right to evade the oncoming truck but was struck and overturned, Rashid said. The van landed in a drainage canal next to the highway.

The person in the other car had to be extricated, officials said.

Once he was rescued, he was taken to San Joaquin County Jail.

All four of the passengers in the vehicle’s rear seats — a 24-year-old man — as well as children aged 10, 9 and 2 — were then taken by responding medical personnel to a nearby hospital for treatment of minor injuries, Rashid said.

The 24-year-old man is a cousin of the children.

The 48-year-old man driving the van and a 45-year-old woman in the front passenger seat died at the scene. Rashid said whether they died by drowning or from injuries suffered in the crash has not been determined.

The 41-year-old truck driver suffered major injuries and was taken to a hospital.

The parents have been identified as Roberto and Maria Bolanos, according to KRON’s Dan Kerman.

Authorities said speed played a factor in the crash. A Go Fund Me Page has been set-up for the family.Bay City News contributed to this report.
