Not just a strong resemblance In My Honest Opinion. That doors got a colon with open dots in it - like the 2nd letter which hadn't been published. Pretty damned prescient, if it wasn't the same guy who wrote that letter who wrote on the door. (And also right in line with the textbook I posted about on "How to Discise yer Handwritting" by some guy that LE would have have been reading. I rote that on anuther thread.)
$64k yes. Why not write a note and bring it with you?
Why not write a letter afterward? Why write on the door? Unanswerable, of course.
BTW I love your "he was consistently inconsistent" logic - it reminds me of the quote in the newspaper of the time from that police officer.... "His pattern is - there is no pattern!" I always find that entertaining.
He was consistently inconstently tall then short then fat then thin. And brown/blond/dark haired (when not gray rust coloured at the back - but could that have been blood?) - but definitely curly. He used different MO's and different weapons each time, damn him.
And I'm still trying to figure out how his feet were a couple of sizes smaller in Riverside than in Berryessa, damnit.
