(Woodland, WA)  --  The search continues for the three missing children of a former Portland-area family killed when their car plunged off a cliff in Northern California.  Police yesterday served a search warrant at the Woodland, Washington, home of 39-year-olds Jennifer and Sarah Hart.  Police found their bodies and the bodies of three of their six adopted children Monday after their SUV went off the Pacific Coast Highway in a remote area of Mendocino County.  Among the children still missing is 15-year-old Devonte Hart, who got national attention in 2014 when a picture went viral of him hugging a police officer during a police brutality protest in Oregon.  Police believe all six children were in the car at the time of the crash.
