The first murder of a couple attributed to Zodiac was not immediately claimed. Only seven months later – an FBI telegram highlights – Zodiac allegedly attributed the murders of David Arthur Faraday, 17, and Betty Lou Jensen, 16, killed in an isolated lay-by along Lake Herman Road, in Benicia, the December 20, 1968.
Why so many months of silence from a serial killer who would be known for his hasty compulsion to claim his own crimes by making calls to the police and sending notes?
Between the summer and early autumn of 1969, the man who allegedly sent twenty letters to various newspapers, signing himself with the name and symbol of a watch brand, phoned the police each time after assaulting a couple.
The first call was received by the Vallejo Police Department on July 5, 1969. It was made from a phone booth located at the intersection of Tuolumne and Springs road, at the “Joe’s Union” gas station (source: Vallejo police report – thanks to Daniele for the report). The second call was made after the attack on September 27, from a car wash booth at the Napa Car Wash.
Officer Nancy Slover, who heard the 5th-July-call (unrecorded), reported the following statement from the killer:
“I want to report a double murder. If you will go one mile east, on Columbus Parkway to the public park, you will find the kids in a brown car. They were shot with a 9 mm Luger. I also killed those kids last year. Goodbye…”
A late claim
The absence of phone calls and messages in the aftermath of the double murder of David Faraday and Betty Lou Jensen differentiates this crime from all other murders perpetrated by Zodiac according to the police.
Lake Herman Road is the only official case (including Riverside) in which neither the media nor the police have received any communication from the murderer, until after many months. What had held Zodiac? Why did he wait so long? Conclusions can be many. The most shared is that, for some reason, the perpetrator of the crime was unable to communicate during that period.
A leave spent in San Francisco in December 1968?
Assuming that Bevilacqua was in San Francisco on his birthday, December 20, 1968, is not improper.
By December 1968, Joe was nearing the end of his Vietnam tour. He was stationed near Saigon while serving for the 27th Wolfhounds Infantry Regiment as an intelligence and operations sergeant in the Headquarters Company (military background disclosed).
All American soldiers engaged in Vietnam for at least one year, in 1968, were granted a short period of “Rest and recuperation” which could also be spent outside Vietnam, in a “neighboring” country, such as Hong Kong, Australia and Hawaii itself (see the cartoon above).
In November 1968, Bevilacqua, who had already been awarded the prestigious Silver Star, obtained, in addition to the Soldier’s Medal, a Purple Heart, for some wounds in combat.
I have not been able to access Bevilacqua’s medical records for obvious reasons of privacy, but it is still possible to suppose that the command would have allowed a heroic wounded NCO to spend his week of R&R leave in San Francisco, the city from which American troops departed and arrived from and towards Vietnam, which housed the headquarters of the 6th Army in the Presidio base as well as the Letterman General Hospital, a reference point for soldiers wounded in the war in Vietnam.
It should be noted that a possible future Zodiac victim, Donna Lass, would have worked as a nurse at Letterman.
Taking advantage of a leave, also for health reasons, on December 20, 1968, the day of his 33rd birthday and the first attack against a couple attributed to Zodiac, Bevilacqua could have been in San Francisco.
Not only. Taking into account that from Saigon to San Francisco the international date line was crossed from west to east, on December 20, Bevilacqua could have had breakfast in Vietnam arriving in time for dinner in San Francisco, a few hours before Zodiac’s attack.
A check on Pan Am airways flights in December 1968 shows that a week’s leave would have been enough for a soldier stationed in Vietnam to commit the murder of December 20th.
Once in San Francisco, the soldier on leave could have rented a car, if he didn’t have one of his own already in the area, drive north of the Bay and come across the lay-by on Lake Herman Road.
And the gun? At the time it was still possible to load weapons in the hold with American airlines (link), so the weapon could even have arrived from Vietnam. But he could also have been in custody at a military base in the San Francisco area.
