SEAL BEACH >> A multi-vehicle crash on the 405 Freeway today killed a 7-year-old girl, critically injured her 13-year-old sister and resulted in the arrest of one of the motorists on suspicion of driving under the influence, authorities said.

The girls’ father was also injured in the 9:15 a.m. collision involving three vehicles on the northbound 405, just north of Seal Beach Boulevard, according to California Highway Patrol Officer Denise Quesada.

The 7-year-old was pronounced dead at Long Beach Memorial Medical Center and her sister was in critical condition, said Orange County Fire Authority Capt. Steve Concialdi.

Their father was admitted to the same hospital in moderate condition, he said. Their names were not immediately released.

CHP Officer Tom Joy said the DUI suspect, who was driving a Chevrolet Tahoe, was in the fast lane when he swerved into one of two carpool lanes, crashing into the Tesla carrying the the father and his daughters. The Tesla then crashed into a Honda, but no one in that car was hurt, Joy said.

The suspect, who was not immediately identified, insisted on being taken to an area hospital for evaluation, Joy said.
