"I noticed a car coming down the road from the direction of Benicia. The car passed in front of me, then I noticed that it came to a stop and its taillights told me it was backing up. Common sense suggested to me to put the sports car in gear and leave. I pulled out and started driving toward Benicia. The other car backed into the area where I had been parked, turned around and in a second or two was behind me. The car hit its bright lights and then did a bright off, bright on, bright off, etc. I went through a few young testosterone moments where I was going “to pull over and kick that guy’s ---”. My former girlfriend started getting upset and I sped up. The car behind me also sped up, and at one point as I was looking over my shoulder the car behind me came up on my side with its right front fender near the driver’s rear quarter panel and appeared to be moving toward making contact. I shifted to a lower gear and hit the gas. There is a fork in the road where one continues toward Benicia and the other more towards the freeway toward Vallejo. The other car was clearly chasing me and I waited until the last moment and then turned off. The larger car behind me could not make the turn. “I went down approximately two hundred yards and stopped in the middle of the road. The other car had stopped shortly after the turn-off. Each of us sat there in the road. Again, youthfully stupid, I yelled about kicking his ---. After some moments, the other car turned around in the roadway and went back down the road from which we had come. I kept making macho statements, but not totally without some sense about me, I drove home. I did not see the car again. I could not see the passenger seat, but the driver was a man with short hair and glasses.
I never told the sheriff who interviewed me that the car I encountered was a Valiant. As I recall, as I was attempting to describe the car, the sheriff came up with a “Valiant”. In the years that have passed, when I have shared the events of that night, I have described the car as a four-door light-colored Chevy. Until your e-mail I have never known that two hunters came upon a white Chevy or that any reference to a Chevy existed in the investigation. I know this does not support the theory of two cars, but it is important to me that my account be accurate". See here.
"If the car was left unattended, the killer may have been out surveying the park area for victims. The scenario is reminiscent of Lake Berryessa wherein several witnesses allegedly saw the killer hanging around the area in the hours prior to the attack". The Zodiac Killer was a hunter and had at least three options available to him, the Lake Herman Road turnouts, the lake itself and Blue Rock Springs Park, all closely grouped within the vicinity. If one failed, he moved to the other and so forth, until the time was right. It is quite plausible he parked up his car in the turnout sometime before 9.00 pm, where it was spotted by Frank Gasser, Robert Connelly and Bingo Wesher. The journey time to Lake Herman from the turnout is similar to Lake Berryessa, in terms of walking distance and quite plausible bearing in mind the hunting aspect and the allusion to 'The Most Dangerous Game', partly described in the Zodiac Killer's 408 Cipher. But something he stated categorically in the 'Debut of Zodiac Letter' pricks the interest. This letter was mailed on August 4th 1969, one month after the Blue Rock Springs Park attack. In it he gives the police an earful. "Last Christmass In that epasode the police were wondering how I could shoot + hit my victims in the dark. They did not openly state this, but implied this by saying it was a well lit night + I could see silowets on the horizon. Bullshit that area is srounded by high hills + trees. 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. When taped to a gun barrel, the bullet will strike in the center of the black dot in the light. All I had to do was spray them as if it was a water hose; there was no need to use the gun sights".
The Zodiac was correct, it was one day after a new moon and 2% illumination, however, parked alongside the Rambler of David Faraday and Betty Lou Jensen, with the headlights on, there was absolutely no need for any type of sighting implement. He could have simply stepped out of his vehicle and fired through the window of the Rambler, exactly like he did at Blue Rock Springs Park. A torch would have sufficed. That is unless his original plan that evening was to head to the lake to do a spot of hunting, whereby a sighting implement may have come in more useful and indicated his true intentions that night. Having possibly found the lake deserted or an opportunity failed to materialize, he returned to the White Chevrolet and the search continued along Lake Herman Road and near Blue Rock Springs Park. Sometime between 9.30 pm and 10.00 pm, William Crow is traversing Lake Herman Road. Enter the white Chevrolet Impala, brake lights on.....
James Owen was another eyewitness who was calculated to have passed the turnout at 11.14 pm on his way to work at Humble Oil in Benicia, describing two cars parked side by side. In his first statement he outlined the murdered couple's car as a "1955 or 1956 station wagon, boxy type, neutral color", but failed to give a description of the second car parked only ten feet to its right, I wonder if it was a white Chevrolet Impala. Six minutes later our final witness, Stella Borges, passes the turnout, the couple are discovered lying on the ground, shot a total of six times. The Zodiac Killer had begun his reign of terror.
