Marvin Margolis was a promising early suspect in the Black Dahlia murder, but he managed to slip through the cracks. So who was this man of many pseudonyms? In this episode, we’ll explore what Margolis did during and after the Dahlia investigation, and a key piece of evidence that potentially links both the Dahlia and Zodiac cases.

The identity of the Zodiac Killer has remained a mystery for decades, but new developments may finally point to an answer. At the center is the infamous Z13 cipher, a 13-character code sent to the San Francisco Chronicle that has long defied experts. Self-taught codebreaker Alex Baber used artificial intelligence and exhaustive analysis to narrow millions of possibilities down to a single name. As his theory gained traction, former detectives and intelligence experts began testing its credibility. The result is a provocative possibility: the name hidden in the cipher may also belong to the man behind another infamous California murder — the Black Dahlia.

On this season of Crimes of the Times, Los Angeles Times journalist Christopher Goffard explores criminal cases that have left a mark on California history. This season’s stories include new developments in the Black Dahlia and Zodiac cases, the snitch scandal that rocked Orange County, the plight of the Japanese American woman known as Tokyo Rose, and the assassination of Robert F. Kennedy.

As part of a malicious prosecution lawsuit, the man who once served as the state’s star witness against Carson admitted his testimony was a pack of lies. In April, Stanislaus County agreed to pay $22.5 million to settle the suit—one of the largest payouts of its kind.

He touts his achievements as a reformer but admits he resents that the FBI excluded him from the jail probe and snuck in the cell phone. His answers are evasive and riddled with falsehoods.
