Elizabeth Short (July 29, 1924 – c. January 14–15, 1947), posthumously known as the Black Dahlia, was an American woman found murdered in the Leimert Park neighborhood of Los Angeles, California, on January 15, 1947. Her case became highly publicized owing to the gruesome nature of the crime, which included the mutilation and bisection of her corpse.
A native of Boston, Short spent her early life in New England and Florida before relocating to California, where her father lived. It is commonly held that she was an aspiring actress, though she had no known acting credits or jobs during her time in Los Angeles. Short acquired the nickname of the Black Dahlia posthumously, as newspapers of the period often nicknamed particularly lurid crimes; the term may have originated from the film noir thriller The Blue Dahlia (1946). After the discovery of her body, the Los Angeles Police Department (LAPD) began an extensive investigation that produced over 150 suspects but yielded no arrests.
Short's unsolved murder and the details surrounding it have had a lasting cultural impact, generating various theories and public speculation.
