California Highway Patrol (CHP) Say The Car's Software Data and A Lack Of Skidmarks Indicates It Was "Intentional".

California Highway Patrol (CHP) say the car's software data and a lack of skidmarks or evidence of braking indicates it was "intentional".
Bodies of five family members have been recovered. Authorities say the three other children are presumed dead.

State child protective services had recently opened a case on the family.

Captain Greg Baarts of the CHP Northern Division said on Sunday night that information pulled from the vehicle's computer shows they had stopped at a scenic pull-off on the side of the road before accelerating about 75ft (22m) across the dirt and directly over the cliff.

"It was pure acceleration from last brake application until it hit the bottom of the ocean - the edge of the ocean," Captain Baarts said, adding that no suicide note has been discovered.

Devonte, 15, Hannah, 16, and 12-year-old Sierra are still missing, but presumed dead. 
Authorities say the missing children may have been washed out to sea. 

The vehicle was discovered on 26 March, three days after child protective services in Washington state - where the family lived - opened an investigation. 

The family's neighbors filed a complaint that the children were being deprived of food. Neighbors Bruce and Dana DeKalb complained to authorities that 15-year-old Devonte had told them that his parents were "punishing them by withholding food". 

We think this happened because these "adoptive parents" were about to be discovered about the ongoing abuse.
