Washington state has agreed to pay $6 million to settle a wrongful death lawsuit over lapses in the cancer diagnosis and treatment of a man who died at Monroe Correctional Complex.

Michael Sublett, 64, died of liver cancer in November 2023 “after a long period of unnecessary and grievous suffering” following “inexcusable delays” and “dereliction of medical responsibility” by the state Department of Corrections, according to the lawsuit filed by his daughter.

Responding to a grievance Sublett filed as he was dying, a DOC official apologized in writing for delays in reviewing ultrasound findings that could have caught his cancer sooner.

The $6 million payout to Sublett’s family, finalized in late August ahead of an October trial date, is the latest in a string of similar cases spotlighted in lawsuits, media and government watchdog reports on problematic medical care in state prisons.

In 2024, the state paid a $9.9 million settlement to a woman whose cervical cancer grew terminal as prison doctors failed to diagnosis and treat the disease. In 2022, the state paid $3.75 million to the family of a man who died at the Monroe prison after his cancer went untreated despite his urgent pleas.

In 2021, the Office of the Corrections Ombuds issued a critical report detailing 11 cases of delayed cancer care, including some leading to other deaths in state prisons.

Chris Wright, DOC’s communications director, said in an email Thursday the agency “has made significant strides in recent years to improve health care for incarcerated individuals,” including a new comprehensive program that focuses on preventive care.

Regardless of crimes they’re serving sentences for, incarcerated people have the constitutional right to adequate medical care and DOC has teams of doctors and nurses at its prisons.

Sublett was serving a life sentence under Washington’s “three strikes” law after being convicted in the 2007 murder of a Tumwater man.

In May 2022, Sublett complained of unexplained weight loss, abdominal pain and serious fatigue. He visited DOC medical staff and concerning lab tests were sent to an outside clinic.
