The Hart family SUV is seen upside down on the rocky shoreline at the bottom of a 100-foot cliff along a remote stretch in Mendocino County, California, about 180 miles north of San Francisco.
A couple vacationing along the coast reportedly spotted a body floating in the water.
Investigators are looking into the possibility that the body may be one of the two missing Hart girls but the sheriff's office said identification will most likely be done through DNA testing, which could take weeks.
Police hadn't found the bodies of Devonte Hart and his adoptive sisters, 16-year-old Hannah Hart and 12-year-old Sierra, after the March 26 crash.
Emotional Campbell gets gold as Australia continue medal rush in pool
Gold medalist Cate Campbell of Australia , silver medalists Bronte Campbell of Australia and Taylor Ruck of Canada on the podium. England are a distant second on 14 total medals, seven of which are gold.
Jennifer and Sarah Hart had adopted all six children and recently lived in Woodland, Washington.
While an autopsy is scheduled for Tuesday, police revealed that the body is that of an African-American female.
Since the accident, authorities have suggested that the crash was intentional. There were no skid or brake marks, said Allman, the Mendocino County sheriff.
Investigators have also said the SUV's software indicates the vehicle stopped at the highway pullout before it accelerated straight off the cliff, according to The Associated Press.

The family of an autistic woman who fled to India are criticising the Ministry of Foreign Affairs for refusing to help them bring the woman home. She was sentenced to community service and one year of probation.
There were no signs of the other two children, authorities said Saturday. 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.
Bruce DeKalb said one of the sons, Devonte, came to his home several times in March to ask for food and said his parents weren't feeding him.
Child Protective Services in Washington confirmed they opened an investigation into the Hart family on March 23. They said they have not found suicide notes.
