Black Dahlia Cold Case May Finally Be Solved, Filmmakers Claim

A team of filmmakers investigating the unsolved 1947 murder of Elizabeth Short, known to the public as the Black Dahlia, say they've found a hidden room inside a Los Angeles motel that may finally reveal where the killing took place, along with new evidence they believe identifies the killer.

Filmmaker Jeff Thomas and producer Kimberly Lupini of Talestorm Productions spent years investigating the case for an upcoming docuseries titled Deconstructing Dahlia. Thomas told People the team now believes it has answers to three of the case's biggest lingering questions. "We believe we know who the killer is," he said. "We believe we know where the murder was committed. We believe we know what the murder weapon was."

A Decades-Old Cold Case

Short, a 22-year-old aspiring actress, was found dead on Jan. 15, 1947, in the Leimert Park neighborhood of Los Angeles. Her body had been mutilated and severed at the waist, with each side of her mouth slashed toward her ear in a wound pattern known as a Glasgow smile. Investigators determined at the time that the absence of blood at the scene meant Short had been killed elsewhere and her body later moved.

The case, nicknamed the Black Dahlia by newspapers of the era, produced more than 150 suspects but no arrests, and it remains one of the most examined unsolved murders in American history.

A Tip Leads to a Motel

According to Thomas, the investigation's turning point came from the son of one of the original detectives on the case, who shared information his father had told him in confidence decades earlier. That detail led the team to an operational Los Angeles motel that has been in business since the 1940s.

With permission from the motel's owner, the team searched the property and eventually located a concealed room. "We found evidence of a major bloodshed event in this room," Thomas said. The team also says it obtained thousands of pages of previously unreleased case files, which it used to cross-reference eyewitness accounts of blood locations with what investigators found inside the hidden room.

Seeking the Autopsy Report

Thomas said the team's next step is securing Short's full, unredacted autopsy report, which the Los Angeles Police Department has never publicly released. He said the report is necessary to confirm a motive for the killing. The team has launched a public petition calling on the LAPD to release its complete investigative file.

Deconstructing Dahlia does not yet have a release date. The case has drawn renewed public fascination in recent years, fueled in part by competing theories in books such as Piu Eatwell's Black Dahlia, Red Rose, which similarly points to an LA motel, though a different one, as a possible crime scene.
