    Zodiac Killer May Be Tied to Black Dahlia Case After ‘Code Cracked'
    2026/06/10
    This episode explores a provocative theory proposed by investigator Alex Baber, who claims to have identified a single perpetrator responsible for both the Black Dahlia murder and the Zodiac Killer crime spree. By utilizing artificial intelligence and cryptographic analysis, Baber asserts that the infamous Z13 cipher decodes to the name Marvin Merrill, an alias for a former medical student and veteran named Marvin Margolis. The sources detail how Margolis’s history as a prime suspect in the 1947 Elizabeth Short case overlaps with his potential as the elusive Northern California killer of the late 1960s. While the evidence includes handwriting comparisons, military records, and alleged sketches of victims, the theory faces significant skepticism from established codebreakers regarding its mathematical validity. Ultimately, the narrative examines whether this modern technological approach has finally resolved two of America’s most infamous cold cases or simply added another layer of speculation to their legends.
