Faces in the Dark: The Suspected Unproven Murderers

After watching The Zodiac Killer documentary, I couldn't shake off the gnawing feeling of frustration. Here was this infamous killer, an architect of terror in California's late 1960s, who taunted authorities with cryptic messages and left a trail of bodies --- and yet, all these years later, he remains unnamed, unclaimed. Leigh Allen, the most prominent suspect, seemed the perfect fit in so many ways. He was obsessive, troubled, deeply enmeshed in dark secrets, and police unearthed an array of circumstantial evidence against him. But that final, condemning link, that irrefutable proof, remained maddeningly elusive. The Zodiac's identity was still a mystery, his shadowy presence haunting us from the past.
