A 43-year-old man and a 42-year-old woman driving in a white Volkswagen Jetta were declared dead at the scene, according to Captain Steve Concialdi of the Orange County Fire Authority.

The pair were reportedly a married couple with a 10-month-old baby at home.

According to Orange County sheriff’s Lt. Jeff Hallock, the 43-year-old driver of the Jetta was attempting to pass a student driver in the northbound lane on PCH when he crashed into a van driving southbound. The accident occurred on a stretch of PCH with a single lane in each direction.

Lt. Jeff Hallock said the victims’ names would not be released until investigators confirm their identities through fingerprint records. The identification process was expected to be completed Tuesday.
