Many have speculated that the Zodiac Killer, after extracting the couple from the Rambler, saw the approaching vehicle of James Owen, shut the Rambler door and forced them out of sight behind the vehicles. Once James Owen had passed the turnout he re-emerged with David and Betty and killed them fairly promptly (James Owen thought he heard a shot about 30 seconds after he passed Gate #10). However, this version of events is almost certainly false, because the shell casing found on the front passenger floorboard of the Rambler by investigators could not have entered the Rambler through a closed door. The passenger door had to be open when the Zodiac Killer began firing.
If the couple were not concealed behind the vehicles, but were in the turnout, then the only logical answer is that the Zodiac Killer forced the couple over to the west bank, where an approaching vehicle's headlights heading towards Benicia would not illuminate the trio. They would be hidden in darkness. Once James Owen had passed the turnout, the Zodiac Killer once again forces the couple back across the turnout, to the illuminated area around the vehicles and begins his murderous exploits. But the Rambler door should have been open in this scenario also. Something that James Owen should have noticed.
The grouping of casings, the position she waa found in the turnout and the bullet pathways discovered at autopsy, clearly shows her direction of travel that night. This apparent switching of positions, with Betty Lou Jensen to the right of David Faraday, when the opposite may have been expected, suggests that they were not murdered immediately after leaving the Rambler. In fact, the possible switching of positions would support the notion of the couple being hidden from view when James Owen passed, who were then relocated back to the side of the Rambler as James Owen disappeared into the distance. This would explain why Betty was to the right of David when the shooting began.
It suggests that when the Zodiac Killer had forced the couple from the Rambler and was about to murder them, he either heard and/or saw the approaching vehicle of James Owen heading up the hill. Trying to avoid being seen by the occupant/s of this vehicle, the Zodiac Killer had about 20 seconds to shepherd the young teenagers to the west bank and out of sight. Why he didn't murder them here and chose to relocate them back to the Rambler may have been a matter of light, or a matter of control. His statement on August 4th 1969 of "all I had to do was spray them as if it was a water hose; there was no need to use the gun sights", may have indicated that he didn't want to rely on his pencil flashlight on the west bank, so moved back to the more favorable area between the vehicles, illuminated on both sides.
