Re: Electric Gun Sight
The Bus Bomb letter was a response to Chief of Police Martin Lee who disbelieved that Zodiac entered the park as he claimed, and claimed Zodiac had left fingerprints. The last time Zodiac was disbelieved was when Vallejo Police Chief Jack E. Stiltz stated after the July 31st letters that he was "still is not convinced the letters and codes were written by the actual killer". The police chief "urged the writer to send more letters, with more facts to prove his connections to the crimes". The Zodiac duly obliged by sending the August 4th 1969 'Debut of Zodiac' letter in response to Jack E. Stiltz, writing about his gun sight. Therefore, when Zodiac is writing "To prove that I am the Zodiac, Ask the Vallejo cop about my electric gun sight which I used to start my collecting of slaves". he is effectively saying "To prove that I am the Zodiac, Ask Jack E. Stiltz, the Vallejo cop about my electric gun sight which I used to start my collecting of slaves".
The statement in the Bus Bomb letter began "To prove that I am the Zodiac". He wrote this because when he declared he was "Zodiac" in the Debut letter, Jack E. Stiltz wasn't convinced that Zodiac (letter writer) was actually the killer, hence why he referred to the gun sight in the Bus Bomb letter to Martin Lee. The Zodiac supplied the extra details of the gun sight in the August 4th communication as "extra details" to prove how he was able to shoot his victims in the dark. So, the Vallejo cop in the Bus Bomb letter is Vallejo Police Chief Jack E. Stiltz.
