Arthur Leigh Allen 8.5 x 11 Vallejo Zodiac Killer main suspect teachers evaluation sheet from 1966

Very rare document ! He was always the best main Vallejo Zodiac Killer suspect with so many evidence added up against him trough time.

Arthur Leigh Allen (December 18, 1933-August 26, 1992) was the prime suspect of law enforcement in the case for the Zodiac Killer. Allen became publicly known as a Zodiac suspect shortly after the release of Zodiac, a book authored by Robert Graysmith. Allen was cleared through a comparison of DNA, fingerprints, palm prints, and handwriting. 

Arthur Leigh Allen died on August 26, 1992 of a heart attack in his home in Vallejo.

Dna was supposed to have cleared him but it didn’t!

The hulking figure of Arthur Leigh Allen casts a long shadow over the Zodiac Killer case. A mountain of circumstantial evidence once made this dead Vallejo pedophile the best suspect for the still-unsolved murders that terrorized the greater Bay Area in 1968-69. Author Robert Graysmith even went so far as to devote his second book on the case, Zodiac Unmasked, to naming Allen as the serial killer.

But just as Graysmith’s book was hitting the shelves, DNA tests conducted by Dr. Cydne Holt of San Francisco’s crime lab for ABC News appeared to clear Allen as a suspect.

In an email sent last week, however, Tom Voigt of Zodiackiller.com says that Allen “is back in the mix” as a Zodiac suspect.

“The partial DNA profile that was obtained back in 2002 by Dr. Cydne Holt for the ABC television show Primetime Thursday was collected from the outside of the stamp,” Voigt elaborates in a forum post. “No genetic material was obtained from behind the stamp, or the seal of the envelope, or anywhere else that would have most certainly belonged to the Zodiac.”

Voigt writes that this information comes from an unnamed retired San Francisco Police Department inspector and was confirmed by Holt. Holt has not returned SF Weekly’srequests for further confirmation. Holt is now chief scientific officer of Verogen, a forensic science startup.
