Again, minority opinion, but the Napa and PH sketches share similar eyes, ears, and noses which means the witnesses likely chose the same shapes from the identikit that the artist presented them with. The PH drawing adds some wrinkles to the face and pouts up the lips a bit but apart from a cheap pair of costume glasses and a date with a Flow-Bee, they're a match. (And since I'm on the subject of haircuts, I'd bet dollars to doughnuts that after Paul Stine, our guy went home and buzzed that iconic crew-cut down to a uniform 1/16" post-haste.)
I place a lot of stock in the Napa sketch, as it's the result of a number of witnesses viewing a suspect under optimal (daylight) conditions for an extended period of time. Lake Berryessa was the only daytime crime the Zodiac is known to have committed and it represents the longest period of time he's spent at the scene and thus, the best possibility of usable forensics. Unfortunately, we know now that the crime scene wasn't properly secured, nor traditionally processed. (Do we have any idea what happened to the discarded cigarette butts the hefty weirdo left behind?)
Maybe I'm just being overly optimistic. After all, if all the physical evidence is at best contaminated and at worst gone, there's some solace to be had in believing that the killer at least showed us his face.
