The children of Terrill Thomas, who died of dehydration in a Milwaukee jail in 2016 after correctional officers turned off his cell’s water supply for a week, will receive $6.75 million in a settlement with Milwaukee County and Armor Correctional Health Services, a private company that provided health care at the jail.

The settlement, reached in the Eastern District of Wisconsin, ends a federal civil rights lawsuit by Mr. Thomas’s estate, which includes four minor children, and a separate federal suit filed by one of his children. Erik Heipt, a lawyer for the estate, said it was the largest settlement of its kind in Wisconsin history, and among the largest in the country.

“The amount of the settlement reflects the callous disregard for Terrill Thomas’s life and the magnitude of his pain and suffering,” he said.

Mr. Heipt said he hoped it would send a message to jail operators that “if you ignore the Constitution and act with deliberate indifference to the lives of inmates, there will be a price to pay.”
