Donald Fouke's description of the likely Zodiac Killer was a "WMA, 35-45 yrs, about 5'10", 180-200 lbs, medium heavy build, barrel chested, medium complexion, light colored hair possibly graying in rear, crew cut, wearing glasses. Dressed in dark blue waist length zipper type jacket (Navy or royal blue). Elastic cuffs and waist band zipped part way up. Brown wool pants pleated type baggy in rear (Rust brown). "
"A white male, 25-30 years old, 5'8" to 5'9", stocky build, reddish-brown hair worn in a crew cut, heavy rimmed glasses and dark clothing."
The second page of the police report was countersigned by Armond Pelissetti and Frank Peda, the first respondents to the crime scene, and was date stamped 6.29 am October 12th 1969. Indicating this typed report was completed only 8 and one half hours after the murder. It states this on the second page
"#2 SUSPECT: WMA, in his early forties, 5'8", heavy build, reddish-blond, crew cut hair. wearing eyeglasses, dark brown trousers, dark (navy blue or black) "Parka" jacket, dark shoes. Suspect should have many blood stains on his person and clothing, suspect may also be in possession of the keys to the Yellow Cab, possibly has wallet belonging to the victim. Last seen walking north on Cherry Street, from Washington Street".
So, who furnished this description in the police report. Since the last line stated "last seen walking north on Cherry Street, from Washington Street" and no future sightings of the suspect were mentioned in the report, one would have to assume the description came from the teenagers. However, the description in the police report appears a mesh of both Donald Fouke's description and the three teenagers. The teenagers stated "reddish-brown" hair, yet Donald Fouke in the memorandum stated "light colored" hair - to become "reddish-blond" in the police report. The teenagers recalled dark clothing, Donald Fouke recalled "brown wool pants" and a "zipper jacket" (navy or royal blue). This was meshed in the police report as "dark brown trousers" and the jacket as a "Parka", navy blue or black. Finally, the three teenagers described the suspect as 25-30 years, wildly different to the police report of a man in his "early forties", but much more in line with Donald Fouke's memorandum of 35-45 years. So who provided the information for #2 SUSPECT?
If the police report is describing part of Donald Fouke's description that night, why has he not countersigned the foot of the report, along with Armond Pelissetti and Frank Peda, despite the fact his observations were apparently crucial to the investigation. We know Armond Pelissetti crossed paths with Donald Fouke that night - and it is highly likely that Donald Fouke shared his observations with Armond Pelissetti, but this should not detract from the fact that Donald Fouke should be pivotal to the Paul Stine police report. However, it is clear his description and observations did surface in the police report, either by his own hand or via Armond Pelissetti.
The teenagers sketch of the Zodiac Killer was amended, with the second version showing a distinctly more furrowed, older portrayal of the first, and believed to have been revised by the teenagers, however, it is equally conceivable it was updated with input from Donald Fouke's sighting.
Thirty-eight years later, Donald Fouke stated in the 2007 documentary 'This is the Zodiac Speaking' "When the composite drawing came out at Richmond Station and was posted on the wall, he looked similar to the man I had seen on October 11th. I then wrote a scratch or inner departmental memorandum to my lieutenant to forward to homicide division, so they would have the additional information about the appearance of the subject." He went on to say "I never spoke to Toschi that I personally know of or remember. He may have been the inspector who came out and asked me about the composite drawing and I told him the suspect was older and heavier, beyond that I had no further contact with the investigation." Despite this statement, there is nothing here that contradicts the notion he most likely informed his superiors of the suspect description the night of the crime.
Since the suspect in the police report was supposedly last seen heading up Cherry Street, then presumably no input had been typed from the Donald Fouke encounter, as this was distinctly a later sighting. Therefore, we have to explain the discrepancy of the teenagers description of 25-30 years, radically changing to a man in his "early forties" on page 2 of the police report. This description could not be accredited to the three teenagers, unless we conceive the notion that the teenagers had a significant change of opinion, and reconstructed the original composite sketch to an older version with no external influence.
But why would Donald Fouke's observations be contained, other than damage limitation, and the embarrassment of letting a suspect slip through their fingers? Despite this, superiors still felt compelled to incorporate his input into the composite sketch to aid in the capture of the killer, which was still foremost in their minds. On the flip side, the police department may have no ulterior motive in containing this encounter, wanting the public and newspapers to concentrate their efforts to apprehending the Zodiac Killer, as opposed to focusing their attention back onto the police department itself.
The Donald Fouke memorandum was deemed a response to Zodiac's revelation of an encounter on Jackson Street, but equally they could have stayed quiet on the matter, simply dismissing Zodiac's claims - and nobody would be any the wiser. After all, Zodiac was deemed a liar and a psychopath by many.
