This Is the Zodiac Speaking is a new documentary on the infamous Zodiac Killer. In the documentary, David and Connie Seawater, who knew the main suspect for the crimes, Arthur Leigh Allen, are shedding new light on whether the man police always suspected was truly the serial killer who sent taunting ciphers to reporters for years and threatened to kill more people if the messages weren’t published in the front page of San Francisco newspapers.
