A body found floating near the California coast on Friday may belong to one of the children missing after a family’s sport utility vehicle plummeted from a cliff late last month, according to the Mendocino County Sheriff’s Office.

The authorities, who said last week that the crash may have been intentional, had already recovered the bodies of Jennifer and Sarah Hart and three of their six adopted children, but the whereabouts of the remaining three teenagers were unknown.

The body recovered on Friday, identified as African-American and female, was found near the crash site and may belong to one of two missing girls — Hannah, 16, or Sierra, 15 — the sheriff’s office said. An autopsy was scheduled for Tuesday.

“The Sheriff’s Office is investigating the possibility that the body may be one of the two missing Hart girls but identification will most likely be done through DNA analysis, a process that can take several weeks,” the office said.
