Did the Zodiac Kill the Black Dahlia? This Crime Writer Thinks So. (Alexander Nazaryan, Aug. 26, 2026, NY Times)
[W]hen two of Connelly’s most trusted collaborators, the retired Los Angeles Police Department detectives Rick Jackson (partly the basis for Bosch) and Mitzi Roberts (the inspiration for Ballard), came to him early last year with the claim that an amateur sleuth in West Virginia had solved the most notorious murder in L.A. history, there was only one thing Connelly could do: work the case as if he were still a young reporter ravenous for the big scoop.
That investigation resulted in “Killer in the Code,” a podcast whose second season returns on Wednesday with the first two episodes of six. The 10-episode first season, which debuted last December, roiled the true crime community by arguing that a World War II veteran named Marvin Margolis was responsible for two of the most famous unsolved crimes in California history: the 1947 Los Angeles murder of Elizabeth Short, immortalized as the Black Dahlia, and the five killings committed by the Zodiac throughout the San Francisco Bay Area in the late 1960s.
“I have no doubts,” Connelly said in the run-up to the second season, which focuses on advancing the case against Margolis as if he were still alive. The evidence pointing to Margolis as the killer, Connelly added, was “completely convincing.”
Margolis has been floated before as a suspect in the Short killing, but never with such confidence. And he has never been previously connected with the Zodiac killings. The podcast has infuriated many in the true crime community. Connelly is viewed by some as a carpetbagger and completely out of his depth, duped by bad cryptography and shoddy evidence, the kind of thing Bosch or Ballard would see right through.
“Mike was a fine reporter, but those reporting days are in the rearview mirror,” said Larry Harnisch, a leading Black Dahlia expert who has led the opposition to “Killer in the Code.” Back when Connelly was a reporter for The Times, Harnisch was a copy editor at the paper. He hasn’t taken kindly to what he sees as the novelist’s intrusion on his domain. “I’m not going to sit silently and let them do it, because it’s a scam,” Harnisch said.
Despite the criticism, Connelly retains a conviction that he has the right guy, dismissing Harnisch and other detractors as a “small incestuous group” peddling “disproved” theories.
“I knew that, going into this, I would put my reputation on the line,” Connelly said.
“They’re invested in a different theory,” he added, “so to accept our theory, they have to accept that they’re wrong, or they’ve wasted a lot of time.”
The gray goatee, the bulky frame, the raspy voice. Michael Connelly, now 70, may be one of America’s most successful writers, but the vibe he gives off is of a cop on the cusp of retirement yet with something still left to prove.
Connelly admits that when he first got involved in the podcast, he did not think it would become something of a second job. (His latest novel, “Ironwood,” was published in May; a new Bosch novel, “The Hollow,” is coming in October.) He would narrate the story of Margolis, and the Black Dahlia-Zodiac link, then go back to writing books. Instead, the story has swallowed him whole.
It all began when he learned that a self-taught investigator in West Virginia claimed to have finally solved one of the Zodiac’s cryptograms. “As homicide investigators like to say, it goes where it goes,” Connelly said.
He can’t just drop it, like a bad first draft. This Friday, he and the rest of the podcast team will present their findings at the Hertzberg-Davis Forensic Science Center, which houses the forensics divisions of the L.A.P.D. and the Los Angeles County Sheriff’s Department.
What keeps him going is an enduring fascination with Short, the patron saint of every lost soul to wander down Sunset Boulevard. “She was missing something,” Connelly said. “That’s the secret of L.A. Everybody here came from somewhere else because they’ve been missing something. Myself included.”
Educated about serial killers by novels, as we all are, both the gap between murders and the wildly differing manners of killing seem awfully odd.
