December 1968. From Saigon to San Francisco

When Zodiac killed a couple of teenagers on Lake Herman Road, Vallejo, on 20 December 1968, was not yet known as Zodiac, and he wouldn’t be for about seven months. Nobody claimed to have murdered David Arthur Faraday, 17, and Betty Lou Jensen, 16, at the time. Investigators were far from identifying the perpetrator until a man who would call himself the same as a dive watch brand phoned the Vallejo Police Department after a second attack in a parking lot at Blue Rock Springs Park. The location of the phone booth was an oil and gas station called “Joe’s Union” (Vallejo Police Department report, thanks to Daniele for pointing that out) at Tuolumne and Springs roads. Agent Nancy Slover listened to the caller and stated that he told her:

«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… Good-bye.»

Zodiac’s phone call, July 5, 1969 

A late claim
It was not until 1969 when Zodiac sent mails to the press and until July 5, 1969, when he first boasted of the double murder of 1968. Why did he wait so long? The absence of phone calls and messages in the aftermath of his first official murder differentiates the homicides of David Faraday and Betty Lou Jensen from the other ones. Lake Herman Road is the only case attributed by the Authorities to him over the years (including Riverside) in which the serial killer did not communicate anything to investigators or the press before more than six months had passed, among other things on the occasion of another attack. What held him back up to that moment? Why did he wait so long?

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 next to 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” leave to be spent outside Vietnam as well. Among the most popular places were Hong Kong and Australia. The standard guaranteed duration was about a week, but the number of days varied according to the destinations. These also included Hawaii (see here and also panel below).

Joe had already been awarded the prestigious Silver Star when, in November 1968, was also conferred with the Soldier’s Medal, the highest recognition for heroism in non combat situation, and the Purple Heart, for some combat wounds.
It can be considered plausible that the command allowed Joe to spend his week of R&R leave in San Francisco, the main city that connected the continental United States to Vietnam, where, moreover, he could have undergone a specialized medical examination for his wounds. In fact, in the Presidio of San Francisco there was the Letterman General Hospital, the main health facility of the 6th Army deployed in Vietnam and point of reference for the soldiers wounded in the war, where Sergeant Bevilacqua could receive more appropriate care than that of a field hospital.
It should be noted that a possible victim of Zodiac, Donna Lass, would later worked as a nurse in the Letterman.
Taking advantage of a leave, also for health reasons, Joe could have been in San Francisco on December 20, 1968, the day of his 33rd birthday, and committed the first murder of a couple attributed to Zodiac, in nearby Benicia.
Considering that flights from Saigon to San Francisco crossed the international date line from west to east, Joe could have breakfast in Vietnam and dinner in San Francisco before attacking the teen couple on that same day, December 20.

Saigon – Honolulu – San Francisco
A check on Pan Am timetables for December 1968 shows that a week’s leave would have been sufficient. Once in San Francisco, Joe could have rented a car, if he didn’t have one already in the area, gone north of the Bay for a ride coming across the lovers’ lane on Lake Herman Road.
And the gun? At the time, it seems that it was still possible to store fire weapons in the hold baggage with the U.S. airlines (link), so the gun could even have come from Vietnam. Perhaps, he kept it in a postal locker or a rented box in the San Francisco area.
According to the Pan Am timetables, Joe could have used at least one of the following 4 periods to reach San Francisco from Saigon with a 7-day special permit, having the time required to commit the murder and return to Vietnam.
