A lawsuit over the death of an 11-year-old California girl who was allegedly tortured and starved by her adoptive family reached a settlement on Friday totaling $31.5m from the city and county of San Diego as well as other groups.

The suit was brought on behalf of the two younger sisters of Arabella McCormack, who died in August 2022. The girls were ages six and seven at the time. Their adoptive mother, Leticia McCormack, and McCormack’s parents, Adella and Stanley Tom, are facing charges of murder, conspiracy, child abuse and torture. They pleaded not guilty to all charges, and their criminal case is ongoing.

The lawsuit said county social workers did not properly investigate abuse claims and two teachers at the Pacific Coast Academy failed to report the girl’s condition. It also said a San Diego police officer, a friend of the girl’s adoptive mother, gave the family a wooden paddle that they could use to hit their children.

San Diego sheriff’s deputies responded to a call of a child in distress at the McCormack home 30 August 2022. They found Arabella McCormack severely malnourished with bruises, authorities said. She was taken to a hospital, where she died.
