 The search continued Wednesday for three missing children of the family whose car plunged off a California cliff last week, as investigators came closer to piecing together a timeline of their final days. 
 
 The California Highway Patrol released a surveillance image from a Safeway in Fort Bragg taken March 25 — a day before the Hart family's SUV was found crashed at the bottom of a rocky shoreline about 15 miles to the north. 
 
 Authorities have said no skid marks were found at the top of the dirt turnout where the GMC Yukon pulled off, and believe the crash may have been intentional. 
 
 The surveillance photo shows mom Jennifer Hart, 38, purchasing bananas and other groceries. It's unclear where her wife, Sarah, also 38, and their six adopted children were at the time.

 The CHP said in a news release it was analyzing the store's footage with FBI agents in an attempt to enhance the blurry viewing quality. 
 
 The investigation has included interviewing neighbors and searching the family's home in Woodland, Washington, about 25 miles north of Portland, Oregon. 
 
 Based on the surveillance footage as well as cellphone pings, police have come up with the family's travel itinerary: They were south of Portland at around 8:15 a.m. local time on March 24, then continued moving south along a coastal route, crossing into Northern California. By 8 p.m., they were in the Fort Bragg area. 
 
 They remained there until about 9 p.m. the next day. At some point, they decided to venture north along Highway 1. And on March 26, just after 3:30 p.m., a passerby called police about an upside down SUV that had fallen 70 feet to the embankment below. ||||| A surveillance video that appears to show one of the Hart mothers is being reviewed as a possible clue in deciphering the route the eight family members took — and in the search of the three children who were reported missing but presumed dead — after their SUV plunged off a California cliff last week. 
 
 Authorities have spent days retracing the "Hart Tribe’s" steps since the family’s battered SUV was found overturned at the bottom of a cliff just off the Pacific Coast Highway, about 150 miles north of San Francisco. The investigation found the family of eight was believed to be in the Newport, Ore. area around 8:15 a.m. on March 24, two days before their vehicle was found, California Highway Patrol said in a Wednesday news release. 
 
 “It is believed they continued south along US 101 until they reached State Route 1 in Leggett, California. The family traveled south along State Route 1 until they reached the Fort Bragg area in Mendocino County around 8:00pm on Saturday evening, March 24, 2018,” the news release read. 
 
 WHERE ARE THE HART CHILDREN? INVESTIGATORS RETRACE ROUTE OF DOOMED FAMILY WHO PLUNGED OFF CLIFF 
 
 A map released by California Highway Patrol showed the coastal route the family possibly took. Authorities retraced the route based on cellphone pings, Officer Cal Robertson told Oregon Live. 
 
 Police said the route goes cold, however, by Sunday night. A surveillance video taken just after 8 a.m. at a Safeway in Fort Bragg appeared to show Jennifer Hart at the register buying bananas and several other items. It’s unclear where the Harts went after the incident. 
 
 Initial reports said there were signs that suggested the family planned for a short trip. 
 
 Their SUV, a 2003 GMC Yukon LX with black rims, was found on March 26 with Jennifer and Sarah Hart, both 38, inside the vehicle. Authorities found the bodies of three children — Markis Hart, 19; Jeremiah Hart, 14; Abigail Hart, 14 — at the scene. 
 
 Devonte Hart, 15, Hannah Hart, 16, and Sierra Hart, 12, are still missing. Mendocino County Sheriff Lt. Shannon Barney said rescuers will be searching the water near the crash site Wednesday morning for the three children, who were presumed to be in the vehicle at the time of the crash, Oregon Live reported. 
 
 On Tuesday, Alexandra Argyropoulos, a former friend of the family, told The Associated Press she alerted Oregon welfare officials about Jennifer and Sarah Hart because she felt they were withholding meals from their six adopted children. Argyropoulos said she "witnessed [in 2013] what I felt to be controlling emotional abuse and cruel punishment" toward the children by the couple, who were living in West Linn at the time. 
 
 "My heart is completely broken. The current system failed to protect these children from their abusers," Argyropoulos said. 
 
 Argyropoulos said she was told the children had been interviewed but there was nothing more the Oregon Department of Human Services could do because there was not enough evidence to make a case. 
 
 CALIFORNIA CLIFF PLUNGE INVESTIGATION FOCUSES ON UNACCOUNTED-FOR HART TRIBE CHILDREN 
 
 A similar instance also prompted neighbors Bruce and Dana DeKalb to alert Child Protective Services three days before the family was found dead. They feared Devonte — who gained nationwide fame after a photo of him at a 2014 Portland, Ore., rally holding a “Free Hugs” sign went viral — was going hungry because he'd been coming over to their house too often in the past week asking for food. 
 
 Authorities attempted to reach the family three times and made their third attempt the day after their SUV was found. 
 
 Investigators believe the deadly crash may have not been an accident — as originally thought — after evidence suggested the driver, Jennifer Hart, accelerated off the side of the road. Court documents stated the speedometer of the SUV was pinned at 90 mph, though authorities warned the device could have been altered at impact. 
 
 The Associated Press contributed to this report. ||||| (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. ||||| This March 20, 2016 photo shows Hart family of Woodland, Wash., at a Bernie Sanders rally in Vancouver, Wash. Authorities in Northern California say they believe all six children from a family were in a vehicle that plunged off a coastal cliff.

 MENDOCINO COUNTY, Calif. (KOMO) - Mendocino County Sheriff's deputies say Jennifer Hart's blood alcohol content at the time of a deadly crash in which her entire family perished was .102, which is above the .08 legal limit. 
 
 Jennifer Hart, along with her partner Sarah and three of their adopted children were killed when their SUV crashed off a cliff in Mendocino County, Calif. on Monday, March 26. Three other adopted children have been reported missing, and police believe they were likely in the car at the time of the crash. 
 
 California Patrol Capt. Bruce Carpenter says toxicology tests also found that Sarah Hart and two of their adopted children had "a significant amount" of an ingredient commonly found in the allergy drug Benadryl, which can make people sleepy. 
 
 
 
 "Facts in the case are coming at a rapid pace," the Mendocino County Sheriff said in a news conference Friday. 
 
 They've also confirmed the Hart family's SUV was about 70 feet from the cliff's edge, when Jennifer accelerated somewhere between 20 to 30 mph and went over the cliff. 
 
 Authorities believe the crash was intentional, but have released no other details. 
 
 Previous allegations of abuse, neglect 
 
 KATU has reported on several other incidents involving Jennifer and Sarah Hart. 
 
 In 2017, one of the Hart children jumped out of a second-story window and begged her neighbors for help. She said her parents were racist, abusive and whipped her. 
 
 In the weeks leading up to the crash, Devonte Hart went to his neighbor's house several times asking for food, adding his parents were punishing him and not allowing him to eat. 
 
 In 2013, a family friend said she "witnessed what I felt to be controlling emotional abuse and cruel punishment" toward the six children. Alexandra Argyropoulos said she was told the children had been interviewed by officials but there was nothing more the Oregon Department of Human Services could do because there was not enough evidence to make a case. 
 
 After reporting her concerns in 2013, Argyropoulos said, she was told the Hart children had been interviewed by officials from the Oregon department; it was apparent that each child had been coached by their mothers on what to say; and nothing more could be done. 
 
 Court records show Sarah Hart pleaded guilty to a domestic assault charge in Douglas County, Minnesota in 2011. Her plea also led to the dismissal of a charge of malicious punishment of a child. One of her daughters, who was 6 years old at the time, showed her teacher she had bruising all over her back and torso. 
 
 And in 2008, a report obtained by KATU says one of their daughters claimed Jennifer beat her using a belt. When confronted by officials, Jennifer and Sarah Hart said the little girl was misbehaving, and added she likely got her bruises from falling down the stairs.
– A timeline of the final days of the Washington family killed in an apparently intentional car crash in California is coming together. Jennifer Hart, 38, was caught on surveillance footage at a Safeway store in Fort Bragg, Calif., around 8am on March 25, the day before the family's SUV plunged off a cliff about 15 miles north of the area, Fox News reports. The bodies of Jennifer Hart (who was driving the SUV) as well as her wife, Sarah, and three of their six adopted children have since been found; authorities are still searching for the couple's three other children. Jennifer Hart was purchasing bananas and other groceries during the Safeway trip; it's not clear where the rest of the family was, NBC News reports. The children ranged in age from 12 to 19; their parents were under investigation for alleged abuse or neglect at the time of the crash. Investigators have also been interviewing neighbors, searching the family's Washington home, and looking into cellphone pings. So far, they know the family was south of Portland by 8:15am March 24, and then drove south along the coast until, by 8pm, they were in the Fort Bragg area. They were there a little more than 24 hours, then headed north up the coast. Their GMC Yukon went off the cliff, falling 70 feet to an embankment below, on March 26; a passerby reported it to police around 3:30pm. Authorities say it appeared to have accelerated over the edge and that no skid marks were found near where it went over. "As of this date it is still unclear if the missing children were inside the vehicle during the incident," the CHP said in a news release, but the missing children are tentatively presumed dead. The local sheriff tells KOIN there is "every indication" they were in the car when it crashed. (A former friend of the couple has come forward to speak out about the alleged abuse.)
