Richard Cottingham, known as the “torso killer” or “Times Square killer,” was convicted of killing five women — three in New York and two in Bergen County — in the 1970s, but he says he’s killed up to 100 over the years. Authorities on Tuesday said the 79-year-old serving life has confessed to killing another woman in the Garden State almost 60 years ago. Cottingham has confessed to killing 18-year-old Alys Eberhardt, a Fair Lawn woman who was found stabbed and bludgeoned to death in her family
