Historian and International Bestselling Author, Peter Vronsky, describes his brief encounter with serial killer Cottingham in a seedy New York hotel that later inspired him to write his bestseller history “Serial Killers: The Method and Madness of Monsters”. In “The New York Ripper” Vronsky explores the history of the notorious Forty-Deuce strip on 42nd Street near Times Square and how it spawned the sadistic monster Richard Cottingham in an era before the term "serial killer" had been coined in popular culture.
Renowned serial homicide expert Dr. Robert D. Keppel said of Richard Cottingham, “I kept asking myself what it was that ultimately intrigued me about the Cottingham case. Partly it was the level of sadistic torture that Cottingham acted out on his victims. He didn’t kill them and desecrate their bodies; he forced them to experience pain and humiliation before he killed them. Then he desecrated their bodies.”
