Louis N. Scarcella, a former N.Y.P.D. detective, was accused of framing dozens of people for murder. The city and state have paid a steep price to settle claims over the past decade.
Prosecutors said the men had been wrongfully convicted in two separate cases, one of which involved a detective linked to the false confessions of the “Central Park Five.”
A fellow inmate, Albert DeSalvo, told him that he was the Boston Strangler who had killed 13 women in the early 1960s. Mr. Nassar’s death, in 2018, had gone unreported.
