A car crash on Sunday fatally injured a pregnant woman and her unborn child, Oceanside police confirmed.
The rollover crash happened at noon on Oceanside Boulevard, just east of Rancho Del Oro. The location is south of State Route 76 and just a few blocks north of MiraCosta College.
Oceanside police found the Toyota Tacoma truck in the westbound lanes of Oceanside Boulevard.
The truck had been traveling eastbound on Oceanside Boulevard when the driver, later identified as a 35-year-old man, lost control of the car for an unknown reason, according to witness statements and evidence found at the scene.
The driver's wife, who was five months pregnant, was in the vehicle at the time of the crash.
The driver over corrected and hit the center median, police said. The car began to roll and came to a rest in the westbound lanes.
The woman was partially ejected from the passenger window, unconscious, with a head injury, police said.
She was flown by helicopter to Scripps La Jolla, where her baby was delivered and taken to Rady Children's Hospital.
On Monday, the woman succumbed to her injuries. The newborn passed away on Tuesday.
The driver suffered minor injuries and was taken to a local hospital, where he was later released.
The investigation into the crash is ongoing.
