Approximating the attack at Blue Rock Springs Park to midnight, had he lived in the vicinity of the payphone, then his journey time from the attack site would have been approximately 10 minutes. Allowing for a further 10 minute turnaround to park his vehicle, ditch his weapon, change his clothes and prepare himself, we are left with a reasonable estimate of 15-20 minutes walking time to the payphone, affording him a reasonable buffer zone to his residence or base location.
Many observers have speculated as to whether the Zodiac Killer knew any of his victims, or had crossed paths with them at any point in time. There is no solid evidence to believe such a relationship ever existed, but to even try to contend one existed, common ground must be sought. If our killer lived 15-20 minutes walking distance from the payphone, then it is reasonable to assert that he likely interacted with neighbors and the local community by way of convenience stores, churches and community centers. Although not fully established, the Zodiac Killer has been touted as having a military connection. It has also been suggested he may have belonged to a secret society, fraternal organization or satanic circle. So, in an attempt to give this notion a fair examination, we must first look at the locale in a 15-20 minute walking radius of the payphone, as well as any possible connections to the victims at Blue Rock Springs Park or Lake Herman Road, where his reign of terror began. To narrow down the search field further, the north side of the payphone was examined first, as it afforded separation from the police station nearby.
On page 31 it states "Joe was interviewed at the Faraday residence, 1930 Sereno Drive. He was a personal friend of David. He states David had no enemies to his knowledge. David met Betty Lou approximately a week ago at the Pythian Castle where they were decorating the hall for a social event".
On page 53 it states "Mrs Faraday stated she did not know Betty Lou that she and David had only been going together for a short time, she had never met Betty Lou. She stated she did not know of any enemies David may have had. She stated that on Friday night at 7:10 pm David drove his sister Debbie to a meeting of the Rainbow Girls at the Pythian Castle on Sonoma Boulevard, and David came back home at 7:20 pm and left again at 7:30 pm. Responding officer talked to Debbie Faraday, WFJ 16 years, sister of David. She relates the following David told her on the afternoon of Friday 12/20/68 that he was going out to Lake Herman Road that night because a bunch of the kids were going out there that night".
Here is an extract from the Calvary Baptist Church: "Calvary Baptist Church held its first services on Sunday, January 13, 1959. Pastor Emmit Duckett and the Fairfield Baptist Church commissioned the beginning of Calvary Baptist Church on February 1, 1959. On that day, the 20 charter members unanimously called Patrick Everitt as their pastor. The first meeting place was the Pythian Castle Hall at 2618 Sonoma Boulevard in Vallejo, California". link.
This following snippet is from the Vallejo Times-Herald newspaper on December 22nd 1968: "The Jensen girl, whose family resides at 123 Ridgewood Ct, was a native of Colorado. She was a junior and an honor student at Hogan High School. She was also grand royal guide of Prima Vera Council 32. Pythian Sunshine Girls".
Albeit one character is reversed, the 340 cipher contains the letters FBC from the Knights of Pythias emblem, on the ninth and thirteenth lines. Had David Faraday and Betty Lou Jensen come into contact with their killer through the Knights of Pythias fraternal organization - and somebody who knew their plans on Friday night. The Pythian Castle Hall at 2618 Sonoma Boulevard is only 24 minutes walking distance from the Springs and Tuolumne payphone. However, there is somewhere that lies inside our 15 minute walking radius from the payphone, that may have some greater relevance regarding the Zodiac Killer and the Knights of Pythias. Listed in the 1969 Vallejo directory under 1020 Alabama Street is The Knights of Pythias Organization 643-6087 and The Navy City Elks Lodge No 1268 643-6087. The Benevolent and Protective Order of Elks is a fraternal order founded in 1868, with veteran services provided by the society. The Elks pledge that "So long as there are veterans, the Benevolent and Protective Order of Elks will never forget them." Wikipedia link. 1020 Alabama Street is approximately 14 minutes or 0.7 miles from the Springs and Tuolumne payphone, that may center the Zodiac Killer's location very close to Alabama Street and Sanoma Boulevard, or indeed The Knights of Pythias Organization and The Navy City Elks Lodge. The Mare Island Naval Shipyard is also in close proximity. However, If the Zodiac Killer did not live in this area, was he a staff member or visitor of these organizations? And did he at any time cross paths with David Faraday and Betty Lou Jensen? It's a slim possibility, but can it be ruled out?
