What are the possibilities that the Zodiac Killer was Arthur Leigh Allen?
In my opinion it is highly unlikely that he was the killer. There were a number of killings in the late 60s, the killer taunted the police with the letters he sent. Someone who does that does not suddenly stop killing or stop taunting the police and live “quietly” for over 20 more years. The killer, whoever he was, either died not long after the last killing OR was imprisoned for some other offence around then and has either subsequently died or is still incarcerated.
