I recently became more interested in the Los Angeles Times articles on Zodiac when I noticed them using the term No 5 and Zodiac then using "no nine" in the same manner in the letter to Belli.

There were many, many Zodiac articles written in the L.A. Times.
1969 ARTICLES - FOUR in 1969 were front page headlines:
*10/15: Chilling Portrait of Madness (FIRST ZODIAC ARTICLE I COULD FIND) - PAGE 1
*10/16: Zodiac Kills Fifth Victim - PAGE 1
10/17: School Bus Drivers Alerted - BA8
*10/19: Hunt Pushed for Zodiac Killer - PAGE AA
10/21: LE Agencies Combine: PAGE 3
10/23: Call to Belli "I want help" - PAGE 1
10/24: Zodiac Calls Belli Again - PAGE 3
11/9: Teacher Poisened - PAGE A
*11/12: He's Killed Seven - PAGE 1
11/22: Man, 33 Shot to Death by Police not Zodiac - PAGE A10
12/28: Letter to Belli - PAGE B
*I have these articles.
