DETROIT (AP) — The Michigan Court of Appeals has ruled in favor of police and dismissed a lawsuit alleging negligence in the 2020 death of a woman who was in custody in suburban Detroit.

There wasn’t enough evidence to let a jury decide whether Harper Woods officers and civilian aides were “grossly negligent” for failing to get medical care for Priscilla Slater, the court said Tuesday in reversing a decision by a Wayne County judge.

The ruling might be different if “Priscilla asked for medical care and was rebuffed, or had she responded that she was not OK when asked, or if she had exhibited clear signs or symptoms of being in physical distress, which were ignored,” the court said.

Slater and a boyfriend were arrested in June 2020 after a disturbance that involved gunshots at a motel.

There was no dispute that Slater, 37, had consumed an excessive amount of alcohol before her arrest. She died of natural causes in a Harper Woods lockup roughly 36 hours later. The autopsy noted that a heart valve had an abnormal shape.

An outside expert told prosecutors that alcohol withdrawal could have been a factor.

Slater’s death caused controversy in Harper Woods. Protesters with bullhorns and signs marched in the streets, accusing city officials of withholding information. Two police officers were fired after the city said they had misled state police who were investigating what happened.

The mayor resigned after saying he understood “why white people would become white supremacists,” a remark apparently made in response to protests by people who are Black. Slater was Black.

In 2021, nearly a year after Slater’s death, Wayne County prosecutor Kym Worthy said no charges would be filed against Harper Woods police.
