SAN FRANCISCO (AP) — A special coroner’s jury in California ruled the deaths of two women and their six adopted children from Woodland, Washington was a murder-suicide after hearing testimony that one of the women had searched death by drowning online and the other deliberately stepped on the gas, sending their SUV plunging off a cliff.

Jurors deliberated for about an hour Thursday before returning the unanimous verdicts that Jennifer and Sarah Hart killed themselves on March 26, 2018, in Mendocino County. The jury decided the six children, 12 to 19, died at the hands of another and not by accident.

The deaths drew national attention, partly because the women were alleged to have abused their children.

Jurors were instructed to choose from four manners of death for each of the eight people: natural causes, suicide, accident or an intentional act by another. They sat through nearly two full days of testimony.

Sarah Hart searched suicide, drowning, Benadryl dosages and overdose methods on the internet throughout the drive to California. She also queried whether death by drowning would be painful. Authorities recovered the deleted searches from her phone.

Jennifer Hart, who rarely drank, had a blood alcohol level over the legal limit and may have been “drinking to build up her courage.” Sarah Hart had 42 doses of generic Benadryl in her system and the children also had high amounts of the sleep-inducing drug in their bodies.
