An amateur codebreaker may have just solved the Black Dahlia and Zodiac killings
When police questioned Marvin Margolis following the murder of Elizabeth Short — who became known as the Black Dahlia — he lied about how well he had known her. The 22-year-old Short had been found mutilated in a weedy lot in South Los Angeles, severed neatly in half with what detectives thought was surgical skill.
Margolis was on the list of suspects. He was a sullen 21-year-old premed student at USC, a shell-shocked World War II veteran who had expressed an eagerness to practice surgery. He was “a resentful individual who shows ample evidence of open aggression,” a military psychiatrist had concluded.
At first, Margolis did not tell detectives that he had lived with Short for 12 days at a Hollywood Boulevard apartment, three months before her January 1947 murder.
Margolis later admitted they had lived together in Apartment 726 at the Guardian Arms Apartments. But he soon moved to Chicago and changed his name, frustrating further attempts to question him. Among many suspects, a district attorney investigator would note, Margolis was “the only pre-medical student who ever lived as a boy friend with Beth Short.”
A generation later and hundreds of miles north, a killer who called himself the Zodiac terrorized the San Francisco Bay Area with five seemingly random murders from 1968 to 1969, taunting police and media for years with letters and cryptograms.
