Search crews in Mendocino County are looking for three missing children of a family killed when their car plunged off a cliff and into the ocean. Investigators have already found the bodies of the two parents and three of their six adopted children. The accident happened Monday when their SUV went off the Pacific Coast Highway in a remote area of Mendocino County. Among the missing children is 15-year-old Devonte Hart. He got national attention in 2014 when a picture went viral of him hugging a police officer during a police brutality protest in Oregon. The family was from Washington State.
