Just throwing something out here, have no particular belief one way or another, it's just that one thing led to another and got me thinking.
Three items:-
1. Zodiac's threat to school kids in the Stine letter.
2. His later claim that he had spoken to/been stopped by Police (specifically 2)
3. The term "Routine Robberies".
I wondered if the threat to kill school kids was directed at the Stine witnesses, given it was first raised in that letter. (I'm not sure if this info could not have been gleaned from the papers the following morning, maybe it was. But Z does appear to have written his letter the very next day.
There was no mention of the Fouke and Zelm's incident until a month later.
He heard of the teen witnesses after the fact and he later heard the rumor that Fouke and Zelms might have stopped someone. Ok he did pass them but didn't think of using that to his advantage until rumors circulated.
Seperately for consideration but also ties in (as inside info could relate to a cop)...the term "Routine Robberies". Is it just me or does that sound distinctly
like a Police term as opposed to one that would be used by an average citizen.? The inclusion of the word "routine" makes it sound like an inside term?
Anyway just musing, I don't doubt there are plenty of explanations.
