The Dahlia Zodiac Connection: Part One

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.
