The Black Dahlia - Part 4 - The Investigation

AI True Crime — Episode Four: The Investigation

Episode Four follows the official investigation into the murder of Elizabeth Short from January through the spring of 1947, examining how the case unraveled almost as quickly as it began.

The episode opens with the discovery of Short’s body in Leimert Park and the immediate failures at the crime scene. Civilians were allowed near the body, footprints were disturbed, and reporters arrived before a secure perimeter was established. From the beginning, evidence preservation was inconsistent and poorly controlled.

We move through the autopsy conducted by Los Angeles County Coroner Dr. Frederick Newbarr, including the cause of death, evidence of prolonged violence, and the bisection of the body. The episode draws a clear distinction between what the coroner documented and what newspapers later exaggerated, particularly claims surrounding surgical skill.

As the investigation developed, police attention narrowed prematurely. The belief that the killer must have had medical training shaped early suspect selection and sidelined other possibilities. This tunnel vision persisted even as evidence failed to support it.

The episode examines the destructive role of the press, especially the competition between Los Angeles newspapers. Details were published before verification, the nickname “Black Dahlia” was coined, and in one infamous incident a reporter contacted Elizabeth Short’s mother under false pretenses to extract personal information. These actions permanently contaminated witness memory and public understanding of the case.

Dozens of false confessions followed, consuming investigative resources and overwhelming detectives. Each confession collapsed under scrutiny, but together they delayed meaningful progress and buried legitimate tips.

As pressure mounted, police focus shifted toward Elizabeth Short herself. Her clothing, movements, and social life were scrutinized in official reports, subtly redirecting blame away from the perpetrator and onto the victim.

Internal conflict within the LAPD further fractured the investigation. Jurisdictional confusion, competing theories, and lack of centralized leadership prevented a unified strategy. Evidence was logged unevenly, and early mistakes became permanent.

By the spring of 1947, momentum had stalled. Detectives were reassigned. The case remained officially open but functionally inactive.

Episode Four concludes by showing that the investigation did not fail because of one dramatic mistake, but because of many small ones made quickly and never corrected. These early failures would define every suspect, theory, and interpretation that followed.
