Mendocino County cliff familicide
CLASSIFICATION: Murder
LOCATION
Mendocino County, California, U.S.
TIME PERIOD
Mar. 26th 2018
VICTIMS
6 confirmed
On 2018-03-26 in Mendocino County, California, Jennifer and Sarah Hart drove their SUV off a coastal cliff, killing themselves and six adopted children. Jennifer was the driver and forensic analysis of the vehicle's data recorder showed the SUV accelerated from a stop and was intentionally driven over the cliff; five children's bodies were recovered and one child (Devonte) was later declared dead though his body was not recovered. A coroner's jury unanimously ruled the deaths a murder–suicide; criminal prosecution was not possible because the alleged perpetrators died at the scene. Key evidence includes the SUV 'black box' data, toxicology showing Jennifer over the legal alcohol limit and Sarah and two children with diphenhydramine, and Sarah's pre-crash internet searches about lethality and drowning.
Some believe the crash was a premeditated murder–suicide: investigators’ analysis of the SUV’s data, Sarah’s Google searches about Benadryl and drowning, and Jennifer’s intoxication have been cited as evidence the mothers intentionally killed the children and themselves. Other lines of speculation focus on whether all six children were actually in the vehicle—authorities and the FBI later treated two children (including Devonte) as possibly missing rather than recovered—and some sources note inconsistencies at the family home (a sterile, unchildlike house and packed but full refrigerator) that have fueled questions about whether the trip and deaths were staged or connected to the recent DSHS investigation and long-running abuse allegations.
In March 2018, Jennifer and Sarah Hart loaded their six children into the family SUV and drove south along the California coast. At some point on that trip, the vehicle left the pavement of Highway 1 in Mendocino County and went over a remote oceanside cliff. [1][2]

Investigators later said that Jennifer and Sarah drove the SUV off a California cliff that month, killing themselves and their six children. [2] The vehicle—a GMC Yukon—had been driven off a coastal cliff into the Pacific Ocean. [1]
On March 26, authorities found the two women dead inside the crumpled SUV. [1] Three of the children lay outside the vehicle, their bodies thrown from the wreck. [1] In all, investigators had pulled five bodies from the wreckage. [1]
Three adopted siblings were unaccounted for. They were missing, and for nearly two weeks, the ocean kept its secrets. [1]
Long before the crash, four siblings—Dontay, Devonte, Jeremiah and Ciera—were born into a fragile family in Texas. [2] Their mother, Sherry Hurd, struggled with long‑term drug use and moved in and out of the house where the children lived with her partner. [2]
By 2004, the state’s attention had turned firmly on the family. Jeremiah was born that year with cocaine in his system. [2] After Ciera’s birth in 2005, Hurd tested positive for cocaine. [2] That same year, when Dontay was eight years old, the state removed him and his siblings from their home. [2]
The foster‑care placements that followed were harsh from the start. In their first foster home, Dontay lashed out and threatened his younger brothers, and the foster mother reported that his eyes rolled back in his head when he was angry. [2] After just seven days, workers separated him from his siblings and placed him in a psychiatric hospital. [2]
He stayed there for three weeks. He later said he was sedated multiple times with a shot that rendered him unconscious. [2] From the hospital he was routed to an emergency shelter, then to a therapeutic foster home for children with severe behavioral problems. [2] By the time he was 10, he had already changed placements seven times; over his childhood in care, that number would climb to 11. [2]

Academically, he slipped behind. While in state care, he fell so far behind in school that by ninth grade he read at a fourth‑grade comprehension level. [2]
Psychiatrists and caseworkers cycled him through diagnoses—bipolar disorder, ADHD, oppositional defiant disorder. [2] The prescriptions piled up: Depakote, Risperidone, Clonidine, Trazodone, Cogentin, Tenex, Concerta, Adderall. [2]
In January 2007, authorities placed the 14‑year‑old in a nonprofit residential treatment center in Houston called Serenity Place, a more restrictive setting than a family home. [2] Staff there documented intimate details of his daily life, down to how many pairs of clean socks he had and whether he brushed his teeth. [2]
For years, the state moved Dontay and medicated him. What it did not do was keep him with his siblings.
In 2006, there was a brief flicker of normalcy. Dontay reunited with his siblings—Devonte, Jeremiah and Ciera—when child‑welfare workers sent the children to live with their aunt, Priscilla Celestine. [2] It did not last.
During a surprise caseworker visit, officials found the children alone with their mother, and removed them on the spot. [2] Celestine appealed the decision to take the children from her care. [2]
The state’s next major decision would split the family for good. Devonte, Jeremiah and Ciera were adopted by Jennifer and Sarah Hart and taken to Minnesota. [2] Dontay was left behind in the Texas foster‑care system and was never adopted by the Harts. [2]

Days after his siblings were separated from him for the last time, 10‑year‑old Dontay tried to kill himself, attempting suicide by strangling himself with a belt at a therapeutic foster home. [2]
Even after the adoption, the possibility of contact remained a live question for the professionals handling his case. When caseworkers asked Jennifer and Sarah Hart whether Dontay could have contact with his siblings, the Harts said no. [2]
By fall 2010, when he was 14, the state sent Dontay to live with foster parent Debra Roberts. [2] Roberts later said that he bonded with her, and that his behavior stemmed from hurt and pain about not being with his siblings. [2]
At 16, yet another move: Nathaniel Davis, his mother’s partner, obtained custody of him. [2] Three years after that, Dontay was arrested in connection with a robbery. [2] By age 19, he was in a Texas prison, serving a three‑year sentence for robbery. [2]
While he was incarcerated, his son, Donyae, was born. [2] He would not learn what had happened to his three younger siblings until October 2018, when he was released from prison. [2]
By then, the GMC Yukon had already gone off the cliff.
Before they headed down the Northern California coast, Jennifer and Sarah Hart were living with their six adopted children in Woodland, Washington. [1][2] In the days leading up to the crash, neighbors in Woodland reported the parents to social workers, alleging possible child neglect. [1]
Those allegations came just before the family left home for what would be their final drive. [1]
Authorities began piecing together the crash once the wrecked SUV was spotted at the base of the cliff in Mendocino County. [1]
Jennifer Hart was 38 years old. [1] Investigators concluded that she was legally drunk when she drove the SUV 100 feet into the Pacific Ocean off a remote stretch of Highway 1, killing herself, her wife and three of their six children. [1] Toxicology results showed that her wife, Sarah Hart, had a “significant amount” of an ingredient primarily used in Benadryl in her system. [1] Two of the children were also determined to have “Benadryl‑type substances in their system.” [1]
The physical evidence pointed toward intent. Authorities said the fatal plunge appeared to have been intentional. [1] There were no skid marks near the edge of the cliff. [1] Based on preliminary reports, investigators said the SUV had stopped about 70 feet from the cliff’s edge, then accelerated off it. [1] The California Highway Patrol’s Capt. Bruce Carpenter said the speedometer was pinned at 90 mph. [1] Carpenter also said no one in the vehicle was wearing a seat belt. [1]

On March 26, rescuers found the two women dead inside the mangled SUV. [1] Three children were found dead outside the vehicle. [1] In the days that followed, search crews pulled a total of five bodies from the wreckage. [1]
Three adopted siblings remained missing.
For 12 days, search crews combed the murky waters off Northern California looking for the three missing Hart children. [1] Authorities believed they were the adopted siblings who had not been recovered from the crash site. [1]
The search was intensive. A team of divers and pilots operated above and below the crash site, scanning the cliffs and the cold water beneath. [1]
The case drew the attention of federal authorities. The FBI issued missing‑persons posters for the three unaccounted‑for Hart siblings. [1] One poster was for 16‑year‑old Hannah Jean Hart. [1] Another was for 15‑year‑old Devonte Jordan Hart. [1] A third listed 12‑year‑old Ciera Maija Hart; on the poster, her name was misspelled as “Sierra.” [1]
An FBI statement warned that “The missing children could currently be traveling together.” [1] At that point, searchers did not know whether the three had been in the SUV when it went over the edge, or whether they had somehow survived and left the area. [1]
On April 7, crews pulled what appeared to be the body of an African American female from the water. [1] Ten days later, on Tuesday, April 17, authorities identified the body as belonging to Ciera Hart. [1] The discovery confirmed that at least one of the missing children had been in the SUV and involved in the fatal crash. [1]
Even then, investigators were cautious. FBI spokeswoman Cameron Rogers Polan said the discovery of Ciera’s body did “not necessarily” place all the children in the SUV. [1] Authorities said they would continue their search for Devonte and Hannah. [1]
Later reporting would state that Jennifer and Sarah Hart had driven the family SUV off the California cliff in March 2018, killing themselves and their six children. [2] But two of those children—Devonte and Hannah—have never been recovered from the ocean.
When the Hart SUV went off the cliff in California, Dontay was locked in a Texas prison cell, serving time for robbery. [2] He had not seen Devonte, Jeremiah and Ciera since they were 4, 2 and 1 years old, respectively. [2]
He did not learn that they were dead until October 2018, when he was released from prison. [2] By then, the search off Mendocino County had ended; the missing‑persons posters had faded from the news; the crash had already been framed as an intentional act. [1][2]
He was the brother the Harts did not adopt. [2] His life had been defined by the very system that was supposed to protect him and his siblings: multiple placements, powerful psychotropic drugs, long stints in residential treatment, and a suicide attempt at age 10 after his final separation from his brothers and sister. [2]
While he struggled in Texas, his siblings were taken to another state by parents who, years later, would be reported for possible child neglect in the days before driving them toward a California cliff. [1][2]
Dontay’s path through foster care unfolded against a broader reckoning with how Texas treated children in its long‑term custody.
In 2011, the advocacy group Children’s Rights filed a class‑action lawsuit against the state, alleging routine moves, overmedication and abuse of children in state care. [2] In 2015, a federal judge ruled that Texas had violated the rights of children in state care and ordered sweeping reforms, including reduced caseworker caseloads. [2]
State officials later reported some changes. Patrick Crimmins of the Texas Department of Family and Protective Services said psychotropic use among children in state care dropped from 30% in 2005 to less than 15% in 2017. [2] State data showed that 54% of sibling groups in Texas were placed together in 2008; a decade later, that figure had risen to 65%. [2]
Nationally, concerns over institutional settings and overmedication helped drive legislative reform. Congress passed the Family First Prevention Services Act, which limits group‑care settings and sets new standards for residential treatment centers to receive federal funding. [2]
Those reforms came too late for Devonte, Jeremiah and Ciera, and for the brother who spent his childhood being moved, medicated and separated from them. [2]
The Hart crash forced the public to confront two failures at once. In Washington and California, local agencies and neighbors had raised flags about how Jennifer and Sarah were treating their children in the days before the SUV went over the cliff. [1] In Texas, years earlier, a different set of decisions had divided four siblings and sent them down radically different paths—one to prison and hard survival, three to a family that would end in a deliberate plunge into the Pacific. [1][2]
What remains is not just the mystery of what exactly happened in the final hours before the Yukon sped off Highway 1, but the quieter question of how many chances there were, along the way, to keep a set of brothers and sisters safe—and together.
