A Danish woman was killed and 11 other people were injured in a three-car accident on Interstate 5 near La Costa, the California Highway Patrol reported.

Rita Korfgaard, 40, of Denmark, was pronounced dead at the scene, the CHP said. The 11 others were being treated at hospitals for a range of injuries, the spokeswoman said.

The crash occurred about 5 a.m. Sunday in the northbound lane of I-5 south of La Costa when a car struck a divider, spun across the other northbound lanes and caused a collision with two more cars, the spokeswoman said.

Three people were thrown from the second car. Many of those injured were not wearing seat belts. Damage to the cars was extensive.

The driver of one car, Oscar Ramirez, 21, of El Monte was jailed on suspicion of driving under the influence of alcohol, the spokeswoman said. It had not been determined who was the driver of the car which hit the divider, the spokeswoman said.
