BYRON -- A child and a young woman were killed Friday in a head-on collision between an 18-wheel semi-truck and a sedan, California Highway Patrol officials said.
The crash, which was reported about 3:19 p.m., occurred on Byron Highway at Clifton Court Road, East Contra Costa fire officials said.
CHP spokesman John Fransen said the 63-year-old driver of the semi-truck was traveling north on Byron Highway when he noticed a blue Oldsmobile sedan, traveling in the opposite direction, swerve as if the driver had lost control of the car.
The Oldsmobile slammed head-on into the big-rig.
Fransen said the 21-year-old woman who was driving the sedan was airlifted to a hospital, where she was pronounced dead from blunt force trauma.
Her identity has not been released pending notification of her family, but Fransen said she was a Bay Point resident.
A boy, believed to be 8 or 9 years old, was pronounced dead at the scene. Fransen said the boy, who was wearing a seat belt, was in the back left seat of the Oldsmobile. His identity also was not released.
It is still undetermined whether alcohol or drugs played a part in the crash.
The driver of the big-rig, an Antioch resident, was not injured, CHP officials at the scene said.
Fransen said the driver of the big-rig was not speeding when the collision occurred; the speed of the sedan had not been determined. The speed limit is 55 mph where the accident occurred.
Weather was also not considered a factor in the collision.
CHP initially reported that three were killed in the accident, but officials later corrected that to two.
The was closed while crews investigated the accident, the CHP said. It reopened at 9:38 p.m.
Cars were stopped a half mile from the scene in either direction, causing mounting traffic delays.
