Child's foot and skeletal remains are found near site where a lesbian mom drove her partner and kids off a California cliff

• A child's foot and skeletal remains were found at the bottom of cliffs in California 
• In March a car plunged 100 feet off a cliff along Highway 1, killing all passengers 
• The SUV was carrying the Hart family, from Woodland, Washington
• Authorities in Northern California say a resident found human remains inside a girl's shoe and a pair of jeans on a beach about one mile north from crash site 
• DNA tests will be conducted a foot found inside a shoe to identify the remains

A Northern California resident found a pair of jeans and human remains inside a girl's shoe on a beach near the spot where a woman drove her large family off a cliff in March, authorities said Thursday.

Deputies responded to the area of North Highway 1 and Hardy Creek in Westport, California around 7.15pm on Wednesday.

A resident had found a pair of girl's size 10 jeans with a girl's size 3.5 shoe entangled inside one of the pant legs.

When deputies inspected the shoe, they found what appeared to be a human foot inside. 

DNA tests will be conducted on the remains to try to identify who they belonged to, the Mendoncino County sheriff's department said.

Sarah and Jennifer Hart and their six adopted children were believed to be in the family's SUV when it plunged off a cliff in Mendocino County, more than 160 miles north of San Francisco. 

The location where the remains were found is about 1 mile north of where the SUV disappeared.

Five bodies were found March 26 but two girls and a boy were not immediately recovered.

The FBI placed a boy and a girl on its missing persons list but investigators said they have no evidence indicating the two children are still alive and officials continue to search the ocean and nearby beaches.

Last month, officials said Jennifer Hart was drunk when she drove her large family off a cliff and her wife and several children had large amounts of a drug in their systems that can cause drowsiness.   

Sarah Hart, along with at least two of the children, had 'significant' amounts of an ingredient found in Benadryl in their systems. 

Her blood alcohol content at the time of the crash was .102. 

Investigators have reason to believe the crash was intentional. 

Five members of the Hart family, parents Sarah and Jennifer Hart and their adopted children Markis, Jeremiah and Abigail Hart, were dead inside the wrecked SUV.

No one in the car was wearing a seat belt. 

On April 7, a bystander pulled a body from the surf near the site of the crash.

The body was later identified through DNA analysis as 12-year-old Ciera Hart.

There are still two missing children, 15-year-old Devonte and 16-year-old Hannah.

Police have said that data from the vehicle's software also suggested the crash was deliberate. 

Hart family's SUV was about 70 feet from the cliff's edge when Jennifer accelerated. She was driving somewhere between 20 to 30 mph when the car went off the cliff. 

They said the SUV had stopped at a coastal highway overlook before speeding straight off the cliff and plummeting 100 feet into the rocky Pacific Ocean below.

The crash happened just days after authorities in Washington state opened an investigation following allegations the children were being neglected.

KATU News has reported on a number of other incidents involving the Hart family that eventually led to an investigation by Washington State Child Protective Services.

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 saying 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.

Sarah Hart pleaded guilty to a domestic assault charge in 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.

In 2008 in another report claimed Jennifer beat her daughter 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.
