Nothing really Z related but the fact that an anonymous caller repeatedly informed her family about that she had been killed, somehow Z style..

*ZODIACHRONOLOGY*
One thing to note is that Cassandra Nadine Landrum disappeared from Union City in Georgia, which is a suburb of Atlanta.
And we have several possible Atlanta Zodiac letters.
Hi, english is not my first language so please bear with me 
At the end of March, 2011, Morf and AK Wilks posted copies of the possible Atlanta Zodiac letters.
Here’s a link:
Union City, Georgia is less than 20 miles southwest of Atlanta, Georgia.
The anonymous telephone calls happened after September 29, 1975, and the letters were sent over five years later in 1981.
I wonder if the parents of Cassandra ever got any letters…
