Richard Cottingham, also known as the "Torso Killer," is serving life in prison for murders he committed in the 1960s and 1970s. While he initially admitted to committing dozens of killings in New York and New Jersey, Cottingham is now owning up to nearly 100 murders amid his old age and ailing health. While discussing Cottingham's crimes, historian Peter Vronsky shared insight into the serial killer's admission that he killed a woman named Alys Eberhardt while speaking to investigative journalist Kristin Thorne for Us Weekly's Uncovered.
