(CNN) A fifth child from the Hart family, killed when their intoxicated adoptive mother drove the family off a California cliff last year, has been identified with the help of the girl's biological mother, police say. She has been identified as 16-year-old Hannah Hart, the Mendocino County Sheriff's Office said in a Wednesday news release. One child, Devonte, 15, remains missing. Jennifer and Sarah Hart adopted two sets of siblings. Sarah Hart and some of the children were sedated when Jennifer got a 70-foot start and accelerated off the cliff without braking.
