The U.S. Court of Appeals for the Second Circuit ruled Monday that former officers from the White Plains Police Department were not entitled to qualified immunity on a motion to dismiss civil claims stemming from the 2011 killing of an elderly and mentally ill black man alone in his city-owned apartment.

The ruling, from a panel of the federal appeals court, revived claims by the family of Kenneth Chamberlain Sr., 68, a U.S. Marine Corps veteran who was fatally shot by police in White Plains after he accidentally activated his emergency medical-alert system.
