Christopher Goffard, reporting for the Los Angeles Times (News+ link):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. The toughest to decipher was the letter he sent in April 1970 to the San Francisco Chronicle, with the words “My name is —” followed by a 13-character string of letters and symbols. It came to be called the Z13 cipher, and its brevity has stymied generations of PhDs and puzzle prodigies. Alex Baber, a 50-year-old West Virginia man who dropped out of high school and taught himself codebreaking, now says he has cracked the Zodiac killer’s identity — and in the process solved the Black Dahlia case as well.
