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.

Attorney Frank Carson spent decades defending the accused in California's Central Valley. He made powerful enemies among law enforcement. When they put him on trial for murder, he insisted he was being framed. He was acquitted after a lengthy trial, but his widow says the ordeal destroyed his health and hastened his death. 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.

In 1986, 29-year-old Sherri Rasmussen was just starting her married life when she was brutally murdered in her Van Nuys home. The LAPD called it a “burglary gone bad,” ignoring red flags pointing to one of their own for years. Detective Stephanie Lazarus might have gotten away with it if she hadn’t left behind a key piece of evidence.

When a helicopter crash killed actor Vic Morrow and two children on the set of Twilight Zone: The Movie, the filmmakers called it an unforeseeable accident. An LA County Sheriff’s detective saw something else: broken laws, reckless risks, and an A-list director who ignored warnings.

On the summer solstice in 1990, a UCLA student with an interest in the occult was stabbed to death in a railway tunnel in the San Fernando Valley. Rumors of ritual violence swirled in the era of the so-called Satanic Panic. Police investigating the murder of Ronald Baker found his killers knew him well. One of them had even carried his casket.

When 21-year old college dropout Christopher Boyce got a job as a clerk at the TRW Defense and Space Systems complex in Redondo Beach, he was given access to some of the country’s biggest government secrets. And under a Robin Hood-like ethos, he and his childhood pal Andrew Daulton Lee began sharing those secrets with the Soviet Union. Their story lived on in the 1985 film “The Falcon and the Snowman,” but their friendship had a much shorter shelf life.
