Looking at the time line (as far as we can determine it), it seems questionable that the doc/son guy was the attacker IF the time of the encounter (as reported by the doc) is accurate:
* Ranger White was contacted by Park HQ at approx. 1855 hours. Before that, two events occured:
1. Fong discovers BH and CS, proceeds to Rancho Monticello - and 2. Mrs. White calls Park HQ.
* Doc/son encounter takes place at approx. 1830 hours.
Even if the doc/son guy was parked nearby (a possibility noted by Narlow - but he also remarks that according to the doc and son, no cars were to be seen near their own), it seems impossible that he could have made it to "Zodiac Island" in time to attack BH and CS before Fong came around in his boat.
Unless...he was seen by the doc and son
after the attack. It seems unlikely at first glance: One would think that Z, after the attack, headed to his car (most likely after having done the writing on B's car door) - and that he proceeded to leave the area immedately. If the post-attack observation theory holds water, he must have headed to the car, disposed of his gear (weapons, costume and jacket), and then for reasons unknown left the car again to do...what? No, it looks like a stretch.
A couple of points I find generally interesting, though - and possibly germane to this...speculation:
* The time of the Napa call (again!). He called at 1940 hours. There is some reason to suggest that it took him longer to get to the phone booth than one should think if the time of the attack (as written on the car door) is more or less accurate.
* The footprints and the tire tracks. These don't add up perfectly. The infamous Wingwalker prints are consistent with the subject moving from Bryan's car to the crime scene (or the other way around, if you prefer). But no prints were found to indicate that the subject had gone near a
second vehicle (namely his own car, which must have been parked where the tire tracks were discovered). This is arguably odd.
And to make it clear: It is possibly relevant because IF his car was NOT parked close to Bryan's, it alters the time line for obvious reasons. How
much it alters the time line is impossible to tell as long as we don't know exactly where he was parked.
