Don't remember the English teacher. Also most of those hitchhiker murders in California in the early 70s were way sicker and more gruesome-sounding than Zodiac, who just shot and stabbed people. All of these things involve dismemberments and rapes and people's heads being found in separate counties from their torsos and shit. Yuuccck. Shudder shudder.
Be advised that while it isn't terribly incriminating that Graysmith thinks Arthur Leigh Allen is definitely Zodiac, so too apparently did the late Dave Toschi, which is a bit worse. Graysmith also claims Cheri Jo Bates (1966) is absolutely a Zodiac victim, but we don't REALLY know that.
1)Zodiac Killer Facts says:
"At one time, Allen did live in his parents Vallejo home less than a block from Darlene’s place of work. However, the available information suggests that while Darlene worked at this location in Vallejo, California, Allen lived in a rented house many miles south in Calaveras County."
2)Well we don't know who Zodiac is so we don't know when his birthday is but ALA's birthday definitely was Dec. 18, 1933. Zodiac allegedly called Melvin Belli's house on Dec. 18 1969 and got Belli's housekeeper and said "today is my birthday."
The big stinkaroo that led them to go after ALA in the first place was his former buddy Don Cheney saying that ALA was going to kill people and call himself the Zodiac. But it's all circumstancial, ehh?
That part was basically tarted up for the movie. Graysmith's final encounter in 1983 at the hardware store with ALA is fictionalized a bit too. The real Bob Vaughn was far older than we saw in the movie.
BTW the guy playing Vaughn is Charles Fleischer, aka the voice of ROGER RABBIT. Also the guy in Back To The Future 2 who says he'd like to back in time and put some money on the Cubbies!
