Westport Calif.-- Authorities in California now say the crash that killed a married couple and at least three of their children may have been intentional.
California Highway Patrol Officials confirmed that the speedometer of the Hart family's SUV, which was found crushed at the bottom of a California roadside cliff on March 26th, was pinned at 90 miles per hour.
Officials say the SUV's on board computer shows that the vehicle stopped at a pullout and then accelerated over the cliff.
The crash killed Washington state married couple Jennifer and Sara Hart, as well as three of their adopted children; 19-year-old Markis Hart, 14-year-old Jeremiah Hart and 14-year-old Abigail Hart.
Their other three children; 12-year-old Sierra Hart, 16-year-old Hannah Hart and 15-year-old Devonte Hart, are considered missing along with two dogs.
Officials still aren't sure when the crash took place.
The hart's were being investigated by social services in Washington after a neighbor complained there children were being deprived of food.
A neighbor Bruce Dekalb said, "I think that it's a little strange that three of them left the vehicle and three of them didn't. So, there's two dogs missing and three children. And where they are, we don't know yet."
Another neighbor Priscilla Hansen said, "I think it's a horrible tragedy to hear and my thought is why adopt six kids and treat them like that."
