Karl Werner murdered Kathy Snoozy, Deborah Furlong (both on August 3, 1969), and Kathy Bilek (April 11, 1971). Because he used the number 7 (instead of 5) and included the month August on the his first instance of the “score” taunt from the Dripping-Pen Card, some have speculated that the Zodiac was claiming to have murdered Snoozy and Furlong.
