New Netflix documentary spotlights Arthur Leigh Allen as main suspect in Zodiac Killer case

A new Netflix documentary, *This is the Zodiac Speaking*, highlights Arthur Leigh Allen as the main suspect in the Zodiac Killer case, which remains unsolved after nearly six decades. Allen was previously identified by police but lacked sufficient evidence for prosecution. Nine men have been linked to the Zodiac murders, including Earl Van Best Jr. and Gary Francis Poste. Recent claims about Poste's involvement have emerged, but the case remains open, with no definitive proof connecting any suspect to the killings. Other suspects include Giuseppe Bevilacqua, Lawrence Kane, and Richard Gaikowski, among others. Each has varying degrees of circumstantial evidence, but none have been conclusively identified as the Zodiac Killer.
