These letters, not only were handled by US Postal staff, but every Tom, Dick and Harry this side of Disneyland. The three July 31st 1969 letters were even retrieved from an investigators house, after he eat his burger and fries off them. I simply am not buying this nonsense, that the 2002 DNA testing was done exclusively on the exterior of the stamps. For this, you would have to believe Cydne Holt, who has a degree in molecular biology, has an IQ of less than zero, along with all the other contributory lunatics in the laboratory. However, if this was the case that stamps were swabbed on the outside, then with the Zodiac case in the hands of mentally challenged people such as these is beyond comprehension.
The entire Zodiac correspondence is evidence. That includes the envelope, the stamp, the stationary, the handwriting. All of it is evidence.
Holt's job was to examine the evidence -- all of it -- and attempt to find DNA. That's what she did.
Genetic material was found behind the stamp but there was not enough to form a DNA profile.
The partial DNA profile she recovered was from the outside of the stamp. Had it matched Allen, or Qvale, or Collins, it likely would have resulted in criminal charges.
