Codebreaker Ties Zodiac Killer To Black Dahlia Murder, Naming Suspect: Report

Alex Baber used AI to crack the Zodiac Killer's Z13 cipher, revealing Marvin Merrill as the suspect linked to both the Zodiac and Black Dahlia murders, supported by former NSA mathematicians.

  • Alex Baber says he decoded the Z13 cipher and revealed Marvin Merrill, an alias of Marvin Margolis, solving the `Black Dahlia` murder, Baber told the Los Angeles Times.
  • The Z13 cipher resisted decryption for decades, while Elizabeth Short, the Black Dahlia, was found mutilated and severed in Leimert Park in January 1947.
  • Using artificial intelligence, Baber generated 71 million 13-letter name candidates and located a 1992 sketch called "Elizabeth" and a likely murder room at 2615 Santa Fe Ave., Compton.
  • Two veteran LAPD homicide detectives endorsed Baber's conclusion linking Margolis to both murders, while former NSA crypto-mathematicians Patrick Henry and Rich Wisniewski verified the Z13 solution; the Los Angeles Police Department says Short's case remains open but not a priority.
  • Longtime case researchers have publicly denounced the theory, with Larry Harnisch calling it fraud and fakery, while critics say Alex Baber is overconfident and underqualified and law enforcement consensus may take time.
