The Zodiac Killings

One call was eventually traced back to a mental health facility in oakland. Recordings of weel's voice were played to those who had heard the real zodiac speak, including lake beriasa survivor bryan hartnell and none thought they were the same person. Weir was interviewed extensively and also provided finger prints and handwriting samples. Investigators confirmed he was responsible for the hoax phone calls to the police department, the jim dumbar show and marvin belley's residence. The real zodiac never responded to belley's public offer of assistance.
