A curious statement by the author of the August 4th 1969 'Debut of Zodiac' letter, when in actual fact only Betty Lou Jensen was 'sprayed' with bullets. This leads to the bigger question - was the style of the attack at Lake Herman Road cemented in our minds as early as the utterances from Sergeant Leslie Lunblad in 1968, in that one person forced both David Faraday and Betty Lou Jensen from the passenger side of the vehicle and shot David Faraday almost immediately by the right rear wheel of the Rambler.
The killer had presumably attached a pencil flashlight to his weapon to aid better sighting, as described in his letter: "What I did was tape a small pencel flash light to the barrel of my gun. If you notice, in the center of the beam of light if you aim it at a wall or ceiling you will see a black or darck spot in the center of the circle of light about 3 to 6 inches across". Then why would he approach David Faraday in near darkness to the point where he could apply a contact wound directly to his left ear, when he could simply have neutralized the male threat immediately, as he attempted to do at Blue Rock Springs and Lake Beryessa? In both these instances the Zodiac Killer kept a barrier between himself and the intended victims. However, in this case we are told, that despite taking the trouble to facilitate a sighting implement on his weapon, he totally negated its use and walked up to David Faraday, to what must have been mere inches, to press the muzzle of the gun behind the left ear of David Faraday. Something doesn't ring true with this scenario. Assuming our killer was less experienced at this point in time, surely more caution would have been applied.
This takes us to the second key point - why didn't the killer just shoot the two teenagers in the Rambler, where they are effectively corralled and contained within the vehicle, as he did at Blue Rock Springs six-and-a-half months later. What was his objective in forcing them from the vehicle into an extremely dark turnout? At Blue Rock Springs, according to Michael Mageau's recollection, the killer remained silent throughout and began firing the instant he arrived by the passenger door. At Lake Herman Road the reverse was the case. The killer, by all the evidence, ushered them both out of the passenger side door and then apparently approached David Faraday to literally within touching distance, in complete contrast to the caution he exhibited in his subsequent crimes. If, however, two assailants were involved in the murders, one could picture an element of bravado, where one assailant feeds off the other - and the concept of intimidating or scaring the victims was an overriding feature.
With eight bullets supposedly recovered from the turnout and at autopsy, the notion of a second vehicle pulling up alongside the Faraday Rambler with two occupants stacks up, in terms of a ratio of 7:1 bullets fired from each particular weapon. Here is the scenario.
The assailants vehicle pulls up approximately ten feet to the right of the Faraday Rambler, and both assailants exit their vehicle immediately. Under this premise, it is obvious that the driver of the second vehicle is closest to the Rambler, so he immediately upon exiting, fires a shot into the right headliner of the Rambler. This was found to have a straight trajectory and embedded in the upholstery on the upper left side of the Rambler. His ejected casing, as he is standing immediately outside his driver side door, flies to his rear, over the vehicle and likely lands to the right side of his vehicle, approximately 20 feet to the right of the Rambler, as shown in the police sketch. If the distance between the two vehicles is slightly greater, say 13 feet, then taking into account the width his vehicle of 5-6 feet, makes the 'stray' bullet casing look anything but stray.
He approaches the Rambler and fires a second shot into the right rear window from approximately 4 feet, accounting for its trajectory of 17-19 degrees relative to the horizontal. His accomplice at this juncture has not yet fired a shot. He is still rounding the unknown vehicle and is furthest from the Rambler, so he is not the instigator to drive the couple from the Rambler. Besides, his partner is effectively in front of him, so firing towards the Rambler is not required, and would present a risk in near darkness of striking his accomplice. The driver of the unknown vehicle has now fired at least two shots, and gestures to the couple to exit the Rambler. Betty Lou Jensen, who is seated in the passenger side, exits the vehicle first and is secured by this assailant. The assailant from the passenger side of the offending vehicle has now arrived, and he now secures David Faraday as he leaves the Rambler, by the right rear wheel of the Rambler. There is now no risk associated with getting close to David Faraday. Betty Lou Jensen is being held with a gun likely pointed at her head. David has no choice but to comply. His assailant is either standing directly in front of him, with the gun pressed to his left ear, making him a right-handed shooter, or he has him secured around the neck from behind, making him a left-handed shooter. David Faraday is essentially powerless to affect the situation.
It may have been the murderer of Betty Lou Jensen who wrote the 'Debut of Zodiac' letter and stated "All I had to do was spray them as if it was a water hose; there was no need to use the gun sights". But he may have 'spoke' out of turn, issuing this statement from his perspective, not the perspective of his accomplice. There is of course no way of establishing which of the couple was shot first, but the above example would play into the scenario of two assailants who wanted to taunt the young teenagers, in particular David Faraday. We also cannot dismiss the testimony of William Crow, who approximately 90 minutes before the double murder was apparently chased along Lake Herman Road by two occupants in a light-colored Chevrolet or blue Valiant (depending on which version you believe). Two eyewitnesses incidentally, who never came forward. Is this because they returned to the turnout sometime after 11:00 pm? This would certainly explain their reluctance to present themselves to investigators.
