Jennifer Hart led her family on a cliff while her wife looked up how much they would suffer, according to a jury

"How long does it take to die from hypothermia by drowning in a car?"

One of his last searches was for a non-kill dog shelter.

They had the intention to kill their 6 children, the jury's findings

The horrible details came on Thursday after the Coroner's Jury unanimously decided that Jennifer and Sarah Hart were planning to die with their six adopted children: Markis, 19, Jeremiah and Abigail, 14, Devonte, 15 , Hannah, 16, and Ciera, 12.

At first, it seemed unfathomable that parents drive their children from their homes in Woodland, Washington, until their death in Mendocino County, California. Their social media pages included pictures of radiant children holding placards "love is always beautiful".

In some pictures, they wore matching t-shirts and a broad smile.

As national attention shifted to the story, more and more details emerged that children were desperately seeking help from neighbors. It has been alleged that their parents abused and deprived the six adopted black children.

The driver is intoxicated to reinforce her courage

The coroner's inquest provided a better understanding of what led Jennifer and Sarah to end the life of the eight Harts.

When the authorities entered the Hart's home, she looked neat, orderly and recently renovated, said investigator Jake Slates of the California Highway Patrol. But while Jennifer and Sarah were decorated, says Slates, the children's rooms were bare.

The investigators found that their luggage had been left behind and that the family had not taken their toothbrush before leaving for two days.

"In my opinion, Sarah and Jennifer have succumbed to a lot of pressure," said Lt. Shannon Barney of the Mendocino County Sheriff's Office. "They came to the point where they made the conscious decision to end their lives and take their children with them."

While Jennifer roamed the US 101 highway, she had five beers in her system, enough for it to make her operation difficult, according to Slates. Witnesses told police that Jennifer rarely drank.

The theory is that she drank to reinforce her courage, said Slates.

"My feeling is based on talking to witnesses who, if they could not have these children, would not have the right to have them," Slates said.

The children asked for help in the middle of the night

A few days before the death of the family in the accident, Washington's Child Protection Services requested a check on the welfare of the family. But no one opened the door on March 26; the family was already gone.

Calls to the police began just two years after the Harts became parents, while they lived in Minnesota. They were first called in 2008 when a child told an adult that Jennifer had hit the child by the arm, but the state filed the case, saying that Child had fallen.

After another appeal in 2011, Sarah Hart pled guilty to assault after confessing to the police that she injured her child by spanking her at the edge of a bathtub.

After the family moved to Woodland, Washington, the children started to visit their neighbor, Bruce DeKalb, for help and food in the middle of the night.

According to a case report, the children also reportedly complained of racist behavior.

Witnesses told the California Highway Patrol that the children were "extremely disciplined, to the point of becoming robotic," walking alone in the bedroom and being told when to go to the bathroom, Slates said.

On March 23, DeKalb called CPS to check on the family. The next day, they parked their sport utility vehicle and began their journey from Washington to California.

Questions remain about monitoring abuses

At first only Jennifer, Sarah and three children were identified.

Jennifer was intoxicated and Sarah and two of the children tested positive for diphenhydramine, an active ingredient in Benadryl.

Ciera's body was found on a beach north of the cliff two weeks later. Parts of a foot in a shoe were found on a beach in May, but investigators were unable to identify the remains as a Hart child until the month of January this year, when a DNA sample proved that it was Hannah's business.

Devonte is still missing and while they think he died with his brothers and sisters, the authorities hope that the public will be able to provide them with information proving that they are wrong.

Jennifer and Sarah can not be questioned or judged for what happened on this California cliff. The investigation is closed and the death certificates now indicate suicide, while the list of children is a homicide.

What may change now, the Mendocino County coroner-sheriff, Thomas Allman, told the press is the federal oversight of the abuses. Five states were involved in the allegations of adoption and abuse of children.

"Where are the systematic failures that could possibly have prevented that?" Allman said. "We do not have a national database on allegations of child abuse."

This, according to Allman, should be an "enlightening moment" for lawmakers.
