Netflix Docuseries Reignites Debate Over Zodiac Killer's Identity

A new documentary explores Arthur Leigh Allen's alleged connection to the infamous Zodiac murders, but fails to provide conclusive evidence.

The Netflix series 'This Is the Zodiac Speaking' features interviews with the Seawater siblings, who knew Arthur Leigh Allen and claim he confessed to being the Zodiac Killer.
Arthur Leigh Allen, the only person ever officially named as a suspect, was a Navy veteran and former teacher with a criminal past, but no definitive evidence links him to the murders.
Despite the documentary's focus on Allen, his DNA did not match samples from Zodiac letters, and no hard evidence was found during multiple searches of his property.
The Seawater siblings recount their childhood experiences with Allen, including trips to locations later connected to Zodiac murders, but these accounts remain circumstantial.
Critics argue that the documentary offers little new information and relies on speculation, leaving the Zodiac Killer case unresolved.
