In the photograph below I have marked the entry wounds 1 through 5, and the positions of the in situ bullets and exit wounds in red. (yellow marks the exit wounds). THE EXIT WOUNDS WERE ON HER FRONT SIDE, BUT MARKED ON HER BACK TO PROVIDE A COMPARISON TO THE ENTRY WOUNDS. It can be noted that all but one of the red circles are left of the entry points. Admittedly bullets can deflect off internal structures, but all five of the bullets went on a right to left trajectory from their entry point, fully discrediting the notion of a Zodiac Killer standing to the rear of a fleeing Betty Lou Jensen. There are two possibilities, either [1] She was running across the line of the Zodiac Killer from left to right or [2] She was likely shot at least 3 or 4 times while prostrate or kneeling on the ground, facing east, with the killer standing almost or very close to a stationary target.

With the cars 10 feet apart the Zodiac Killer could still stand between the two vehicles, with the expended shell casings being ejected to his right and rear, in the pattern exhibited in the police sketch, however the relationship between the Rambler and Betty Lou Jensen in the sketch is totally inaccurate. I have designed a new sketch depicting a second vehicle 10 feet to the right of the Rambler, Zodiac standing between, or slightly front of them, showing the casings can still be ejected to the right of the Faraday Rambler, and still facilitating the killer to be standing close to Betty Lou Jensen. From this position, Betty Lou is facing east, perpendicular to the two vehicles, but effectively a sitting duck, either lying prone or crawling. From this position the shooter creates approximately a 45 degree angle to the horizontal, and a trajectory that mimics the autopsy results where every exit point or bullet resting position is considerably left of the entry point in each and every example. It is these autopsy findings that makes a rear firing shooter, standing behind Betty Lou Jensen, while she is running for her life, a myth that is simply not backed up by the scientific facts.
In the image below the rough position of Zodiac can be shown, or somewhere close to the white circle.
