Zodiac Movie vs. Zodiac Killer True Story

What is the current status of the Zodiac case?
Three Zodiac letters that were lost for 20 years surfaced in 2002 during research conducted by ABC for its Primetime news program. The letters are going to be tested for DNA, and if a DNA profile can be built, it will be compared with millions of other profiles in national databases. Detective Mathew Meredith in Vallejo, Ca, believes that the DNA from the lost Zodiac letters could finally lead to some answers. "Hopefully, it will turn something up," Meredith said. "And if it doesn't, this is kinda stirring the pot, and we'll see what floats to the surface."

Are there any other likely Zodiac suspects besides Arthur Leigh Allen?
Yes. As the movie Zodiac emphasized, there were 2,500 suspects in all. What initially drew Robert Graysmith to Arthur Leigh Allen was something that a Stanford professor had told him. Dr. Lunby at Stanford said that whoever the killer is he will have offered to catch himself. When Graysmith called investigator Dave Toschi, he asked Toschi if he had ever received that type of letter. "Toschi replied, 'I only got one, I just got it!' He takes it out and it's from Arthur Leigh Allen from prison and it says, 'Sorry I wasn't your man, blah, blah, blah...'" Circumstantial evidence then began to mount against Allen. David Fincher's movie, which is based on Robert Graysmith's Zodiac books, concludes itself with Graysmith's belief that Arthur Leigh Allen is the man responsible. It should be noted here that other high profile Zodiac suspects have existed since 1968.
