(Mendocino, CA)  --  Police in Northern California say it appears that a crash that killed at least five former Portland-area family members last week was intentional.  Search crews have recovered the bodies of parents Jennifer and Sarah Hart and three of their adopted children after their SUV drove off a cliff in Mendocino County on March 26th.  Three other children are still missing and California Highway Patrol says they could have been swept away by the ocean.  Police still don't know which parent was driving at the time of the incident.
