Another body, believed to be one of the missing Hart children, was recovered from the ocean on April 7. The discovery comes after investigators found personal items belonging to the Thottapilly family in the Eel River.
Earlier the authorities announced they were able to locate numerous items that appeared to have come from the vehicle belonging to the missing family.
The Harts moved last spring to Woodland, Washington, telling their real-estate broker "they needed a fresh start" after experiencing prejudice in Minnesota and too much media attention in OR after one child was pictured in a viral photo taken at a 2014 police-brutality protest.
A neighbor of the Harts in Woodland, Washington, had filed a complaint, saying the children were apparently being deprived of food as punishment.
After Sarah Hart pleaded guilty to a misdemeanor charge of domestic assault, she and Jen pulled their children from schools in Minnesota, in favor of homeschooling.
The mother said her daughter told her a boy pushed her down causing injuries.
Jennifer and Sarah Hart were white; their adoptive children were black.
Almost four months before the fatal crash, a neighbor phoned 911 to report an episode in which one of the couple's children desperately sought help, CNN reported.
The girl, who was 6 at the time, was also found with large bruises on her back and stomach, and said her mother struck her with a closed fist. There was no SUV mention in the case notes, which says the business card from the first call was no longer in the front door.
Deputy Bill Holcomb looks down the cliff near the crash site near Mendocino, Calif., as search and rescue volunteers scour the area behind him on Thursday, March 29, 2018, and resume looking for three children, still missing after their parent's SUV plunged into the ocean Monday.
The announcement came during a Mendocino County Sheriff's Office news conference updating reporters on their efforts to locate Southern California resident Sandeep Thottapilly, his wife and two children whose SUV is believed to have plunged into the Eel River.
But what most alarmed Argyropoulos was that Hart repeatedly withheld meals from the children, who appeared constantly hungry.
The 100-foot drop killed the women, both 39, and their children Markis Hart, 19; Jeremiah Hart, 14; and Abigail Hart, 14. The authorities described the Thottapilly family as 'loving and happy.' The California Highway Patrol (CHP) -Garberville confirmed that the body of a victim and personal belongings of the family have been recovered from the river.
A toxicology report revealed that Jennifer Hart had a 0.102 alcohol level, California Patrol Capt. Bruce Carpenter said.
There were no skid marks at the scene, Carpenter said.
