The Mendocino County Sheriff's Office on Wednesday said deputies will keep searching the county coastline for the missing children as calls for service allow and that search and rescue divers are readying to be deployed to the crash site area once ocean conditions improve. Two officials returned March 26 - the day the Harts' SUV was found - and the card from the Friday before had been removed. Authorities found the bodies of Sarah and Jennifer Hart and three of their adopted children, Markis, Jeremiah and Abigail. The Harts' three other adopted children -- Hannah, 16; Devonte, 15; and Sierra, 12 -- are missing, but investigators have said they believe the whole family was in the SUV at the time of the crash. The vehicle appears to have left a highway for a dirt turnout, then accelerated on that turnout for about 70 feet until it went off the cliff, authorities said, citing data from the vehicle's software and air bag module. PORTLAND, Ore. -- One of the mothers who died when an SUV plunged off a Northern California cliff sent a text two days before the wreckage was discovered, saying she was so sick she might have to go to a hospital, according to 911 call records from Washington state. The Harts moved to a home in Woodland, Washington, in mid-2017, recalled neighbor Bruce DeKalb , who said he had two sets of disturbing encounters with the children after the move. An official went to the family's home, knocked and rang the doorbell and left her card in the front door, records said. Hart said she had checked hospitals, but none said they had a record of treating Sarah. Other records released to The Oregonian/OregonLive this week from the Washington State Department of Social and Health Services show Child Protective Services initially tried to contact the Harts on March 23 after abuse allegations were made against them by the family's next-door neighbors. In 2011, Sarah Hart was convicted of domestic assault in Minnesota for physical abuse involving one of the children who was then 6 years old, according to court records. In 2014, Devonte garnered national attention when he embraced a white police officer at a time when racially charged protests were being held across the country following a grand jury's decision not to indict the white Missouri police officer who killed Michael Brown, an unarmed black man.
– A social worker in Washington state wasn't the only person to call 911 in reference to the Hart family around the time their SUV plunged off a seaside cliff in California. Shortly before the SUV was found on March 26 at the bottom of the 70-foot cliff alongside five bodies, a friend called 911 to say she'd been unable to reach Sarah and Jennifer Hart since receiving a text from Sarah at 3am on March 24. Sarah had said in the text that she was feeling sick, wouldn't be at work, and might have to visit a doctor, reports the Statesman Journal. "We're just concerned," Cheryl Hart, unrelated to the family, told a dispatcher, per CBS News, adding she'd already checked local hospitals. Unbeknownst to her friend, Sarah's text had been sent hours after a child welfare official visited the Hart home in Woodland, Wash., acting on a call from a neighbor who said the couple's six adopted children weren't being fed. Jennifer Hart had just returned home from work but didn't answer the door, per CNN; a card left at the door was later found to have been removed. By the next morning, the family was gone. A surveillance video shows Jennifer buying groceries in Fort Bragg, Calif., on the morning of March 25. The bodies of Jennifer, Sarah, and three children were found the next day at the bottom of a cliff 15 miles away. The Harts' three other children are believed to have been in the vehicle at the time of the crash. (Another body was recently found near where the crash occurred.)
