Elizabeth Short was an American woman found nude,  murdered in Los Angeles, California, in 1947. She became know as the "Black Dahlia."  The case was highly publicized due to its gruesome nature, and remains unsolved. 

The Zodiac killer,  pseudonym of an unidentified serial killer, murdered at least five people in the San Francisco Bay Area over the span about nine months.   He claimed in letters to have killed 37 people, but he was never identified. 

A new book suggests a conclusion, a connection between the death of the "Black Dahlia" and The Zodiac killer.  Alex Baber, Director at 'Cold Case Consultants of America'  says he's used AI and his codebreaking skills to crack the Zodiac Killer's letter. The Zodiac Killer and Black Dahlia killer are the same.
