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. On March 26, Cheryl Hart called a Clark County emergency dispatcher to report that she had not heard back from her friend in two days. 
 
 Cheryl Hart of Vancouver, Washington, said she received the alarming message from Sarah Hart at 3 a.m. March 24, The Oregonian/OregonLive reported Wednesday. Cheryl Hart shares the same last name but said she's not related to the family. 
 
 CBS affiliate KOIN has obtained audio from the 911 call, which was placed on Monday, March 26. It sheds new light on the final days of the Hart family. 
 
 "She sent out a text message at 3 in the morning on Saturday morning [sic], saying that she was sick, but nobody's been able to get ahold of her, talk to her, or seen her since that text message," the friend told the dispatcher. "Or her wife, which is Jen. So we're just concerned." 
 
 Hart said she had checked hospitals, but none said they had a record of treating Sarah. 
 
 Several hours after she called authorities, the family's SUV was discovered at the bottom of a scenic Mendocino County cliff. 
 
 Authorities found the bodies of Sarah and Jennifer Hart and three of their adopted children, Markis, Jeremiah and Abigail. Three other children, Hannah, Sierra and Devote, are still missing. On Saturday, a body was pulled from the surf in that area and authorities are working to determine whether it belongs to one of the children. 
 
 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. 
 
 An official went to the family's home, knocked and rang the doorbell and left her card in the front door, records said. Two officials returned March 26 - the day the Harts' SUV was found - and the card from the Friday before had been removed. One of the officials left another card and called law enforcement and requested a welfare check. 
 
 A deputy went the same day to the home in rural Woodland, Washington, and no one appeared to be home, records said. 
 
 Authorities returned the next day, and no one appeared to be home again. 
 
 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. The family also was investigated in 2013 when they lived in Oregon after a family friend reported witnessing "controlling emotional abuse and cruel punishment" toward the children. 
 
 Authorities said previously that data from the vehicle's software suggested the crash was deliberate. They said the SUV had stopped at a coastal highway overlook before speeding straight off the cliff and plummeting 100 feet (31 meters) into the rocky Pacific Ocean below. 
 
 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. 
 
 One of the missing children is Devonte, 15, who drew national attention after he was photographed in tears while hugging a white police officer during a 2014 protest. ||||| (CNN) An autopsy is scheduled Tuesday for a body found near the Northern California site where an SUV plunged off a cliff last month, killing at least five members of a family in what investigators suspect may have been an intentional crash . 
 
 But it could take several weeks to determine whether it's the body of one of three children still missing after the crash because lengthy DNA analysis may be needed for identification, the Mendocino County Sheriff's Office says. 
 
 Vacationers found the body of an African-American female floating in the Pacific Ocean surf Saturday, nearly two weeks after the SUV carrying the Hart family plunged off a cliff and onto a rocky shoreline in a remote stretch in Mendocino County, about 180 miles north of San Francisco. 
 
 The bodies of Jennifer and Sarah Hart, both 38, were found March 26 inside their crashed SUV. The bodies of three of their adopted children -- Markis, 19; Jeremiah, 14; and Abigail, 14 -- were found nearby. 
 
 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. 
 
 Police have said no one in the SUV was wearing a seat belt and that seawater might have swept away the missing children. Searchers found nothing further Monday, the sheriff's office said. 
 
 The crash came as child protection personnel in Washington state were trying to visit the family after a neighbor said he reported a child's complaint of mistreatment. 
 
 Investigated as a crime 
 
 The bodies of Jennifer and Sarah Hart and three of their six kids were found in and around their SUV. 
 
 Mendocino County Sheriff Tom Allman has described the crash as "a crime." 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. 
 
 No skid marks were seen in the area, officials said. 
 
 "I'm to the point where I no longer am calling this an accident," Allman told HLN last week. 
 
 There were no witnesses to help guide police. A passer-by discovered the SUV, seeing the mangled wreckage at the foot of the cliff. 
 
 A family's troubled history 
 
 The family's history, including allegations of child abuse and an investigation by Child Protective Services in Washington state, provides clues as to why Allman said he is investigating the case as a crime. 
 
 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. 
 
 "One of the girls came to the door at 1:30 in the morning and said that she needed help and the parents were not treating her properly, and (she) wanted us to protect her," DeKalb said, describing the first encounter. 
 
 "We ended up getting her back to her parents, ... and then I went over there the next morning and just checked on things, and everything seemed normal, and we let it go from there." 
 
 Then in March, DeKalb said, Devonte began "coming over asking for food and saying that they were taking meals away from him due to punishment." 
 
 "It started out as one time a day and escalated up to three times a day until a week went by, and we decided that we needed to get professional help," DeKalb said. 
 
 State officials alerted 
 
 DeKalb said he called the state's Child Protective Services office on March 23. Officials arrived just after Jennifer Hart came home from work, but she didn't answer the door, he said. 
 
 Sarah Hart came home soon after that, DeKalb said. By the next morning, the family and its vehicle were gone. 
 
 Officials tried to visit the family twice more, on March 26 and 27, but couldn't make contact, the Washington State Department of Social and Health Services said. 
 
 Sarah Hart earlier had faced allegations of mistreatment in Minnesota, where she and Jennifer lived when the children were adopted about a decade ago from Texas. 
 
 In 2010, Sarah Hart pleaded guilty to misdemeanor domestic assault involving one of the children, according to Douglas County, Minnesota, court records. 
 
 She told police she had spanked the child over the edge of the bathtub because of the child's behavior. She was sentenced to community service and one year of probation. 
 
 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. 
 
 Devonte helped quell tensions with his sign offering "Free Hugs," and his photo was shared around the world.
– 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.)
