Julie, didnt really consider Richard Haefner a suspect in the Biechler case,more a POI,as well as a POI in the Aardsma case. He coincidentally was from where Biechler lived,he was at college same time as Aardsma,and he wrote a research paper in Calif in the 60's. Despite all of that, i havent been able to conclusively link him with any Zodiac crime. Also, he moved out to Calif at some point and while out doing research in the desert,died of a heart attack in 2002.
This connection i have made between the Zodiac and this Houston double homicide shows that the anonymous letter was received by police in 2001,and while haefner could have been involved i doubt he was.
In addition, in fanning out my search from Houston, i found the League City Tx. murder of Laura Lynn Miller. She was shot with a .22 in the mid 80's. Over 20 years later(i believe it was 20 years later( her father received an anonymous letter. It was filled with Zodiac-like references,words,etc. This would have been AFTER HAEFNER DIED. I am so sure that this Houston & League City activity is Zodiac,that I can safely rule out once and for all in my mind Zodiac suspects, ALA (He was already dead) Manson family member Bruce Davis ( He was in jail) Ted Kazcynski "unabomber" (He was also in jail),ad POI Haefner.
If there isnt a Laura Lynn Miller thread already, i will be adding one. Stay tuned!
