The Zodiac Killer’s cryptic messages weren’t just taunts to police — they were a twisted throwback to his first victim, according to an independent investigator who says he’s cracked the code and uncovered new evidence suggesting the infamous serial killer began his career 23 years earlier with the California murder of Elizabeth Short, also known as the Black Dahlia.
Alex Baber, co-founder of Cold Case Consultants of America, said that after nine months of work, he cracked a double-layered encryption that involved transposition and substitution in a 2 by 7 grid.
“Currently, for the first time in history, LAPD detectives approached the family of a suspect to obtain DNA,” he told Fox News Digital in an interview on the sidelines of the Hamptons Whodunit event in East Hampton over the weekend. “That’s never happened for the Black Dahlia case… we got a pretty good feeling that we’re sitting in the right seat.”
The Los Angeles Police Department did not immediately respond to a request for comment. An FBI spokesperson declined to weigh in.
Baber’s finding, that the Zodiac’s “Z13” cipher depicts the name of a prime suspect in the 1947 Black Dahlia murder, was first revealed in the Daily Mail, and he presented them publicly Saturday at the East Hampton Library.
With help from a proprietary artificial intelligence software and self-taught knowledge of cryptography, he said the 13-character message is decoded to read “Marvin Merrill.” After further digging into social security records, he said he discovered that’s an alias for Marvin Margolis, who he said dated Short in the 1940s and had been on the LAPD’s suspect list after her murder and dismemberment. His AI software flagged the connection between the two cases, he added.
