In 1947 Elizabeth Short, The Black Dahlia, was found dead in a vacant lot in LA, her body surgically bisected at the waist and horribly mutilated. For almost 60 years, the Black Dahlia case has been one of the most horrific unsolved murders of the 20th century. Larry Mantle talks with author Steve Hodel, former LAPD homicide detective, about his investigation into the murder and his claim that the killer was his own father, Dr. George Hodel. Steve Hodel's book is called Black Dahlia Avenger: A Genius for Murder (Perennial).
