While an autopsy is scheduled for Tuesday, police revealed that the body is that of an African-American female.
16-year-old Lexi Rae Hester was house sitting for her aunt and uncle when the fire happened.
A couple vacationing reportedly saw the body and pulled it from the surf before calling authorities.
Upon learning that three other children are unaccounted for, officials launch a further search-and-rescue effort along the ocean waters to locate Hannah, Devonte and Sierra.
A CHARITY has reunited a family with the cremated ashes of their relative after they were accidentally donated to a furniture store. Authorities also found no skid marks at the edge of the Mendocino County cliff. There, the couple's neighbors recalled unusual encounters with the Hart children.
In 2013, a former friend of the Hart family told child welfare officials in OR in 2013 that Jennifer and Sarah Hart deprived the kids of food as punishment.
The agency was trying to get in touch after the "now deceased children were identified as potential victims of alleged abuse or neglect", according to a statement from the Washington State Department of Social and Health Services. Devonte captured the world's attention in 2014, when he was photographed sobbing in the arms of a white police officer in Portland, where people had gathered in support of civil rights protests in Ferguson, Missouri.
Siblings Jeremiah, Sierra and Devonte are officially adopted from Harris County, Texas, Butler said. They said the teen claimed his parents were "punishing them by withholding food".
Allman, the Mendocino County sheriff, says there is "every indication" all six children were in the SUV when it went over the cliff, though he says it's possible the three missing children were left with friends.
The sheriff's office says if it weren't for Sam, the family might not have detected the fire until it was too late. They remain in Fort Bragg for about a day, authorities said.
