After exiting his vehicle the Zodiac Killer approached the Corvair and began shooting the couple. Subsequent to the attack (at about 12:02am on July 5th 1969) he got back in his vehicle and then drove away towards Springs Road for a second time. Michael Mageau was able to recall the assailant's vehcle had a California license plate. The Zodiac Killer, without knowing the automobile proficiency of the couple in the Corvair, especially after parking his vehicle alongside theirs for about one minute - and entering and exiting the parking lot twice - must have been aware that there was a reasonable possibility the couple had recognised the make and color of his vehicle. He even drove away from the crime scene slowly according to his story.
The Zodiac Killer, if he was familiar with Blue Rock Springs, also knew that there was a reasonable possibility that the nine shots he fired that morning may have been heard by the caretaker and/or residents of the house approximately 800 feet from the parking lot. George Bryant stated that "he could hear laughing and a few firecrackers being set off. And at approximately midnight he heard what appeared to be a gunshot. This was much louder than any of the firecrackers. A short time later he heard what appeared to be another gunshot. After another short pause he heard rapid fire of what appeared to be gunshots. He then heard a car take off".
The Zodiac Killer's vehicle had been viewed by Michael Mageau and Darlene Ferrin for at least 2 minutes that night/ morning, and he had fired off 9 shots in total. If he had planned to make a phone call that morning, the obvious choice was to do this immediately before police were alerted and his vehicle description was sent out over the airwaves throughout Vallejo. But wait I hear you say; Zodiac probably thought the couple were dead. After all, his phone call to Nancy Slover stated "I want to report a double murder. If you will go one mile east...... On Columbus Parkway to the public park, you will find the kids in a brown car". This gives the impression that he thought he had killed two people - but this claim was bullshit - and he knew there was a distinct possibility he had only killed one person that morning.
Michael Mageau was last described by Zodiac as thrashing around violently in the back seat when he shot him in the knee. The Zodiac Killer must have known that a knee shot was not a terminal injury, knew that there was a strong possibility that Michael Mageau was still alive when he left the parking lot at Blue Rock Springs, knew that Michael Mageau had the ability to have seen his vehicle for at least two minutes, knew there was a possibility his 9 shots were heard in the vicinity of Blue Rock Springs, and understood that the crime scene may have been discovered fairly quickly,
Understanding all this and knowing the make and color of his vehicle could be all over the Vallejo airwaves fairly quickly, is it reasonable to conclude he drove around Vallejo for approximately 40 minutes, before parking his vehicle adjacent to a payphone, only 830 meters from the Vallejo Police Department? He also leaned into the Corvair to target Michael Mageau in the back seat, leaving two spent casings on the rear floorboard of the vehicle, which had the potential to transfer blood to his shirt from the passenger seat.
Taking all these circumstances into account, it is far more reasonable to conclude he drove home, concealed his vehicle, ditched the smoking gun, changed his clothes, and then headed to the payphone on foot to make the call. This would explain why the phone call to Nancy Slover was logged at 12:40am, when the journey time to the payphone from the murder scene was only 9 minutes. If the Zodiac Killer had made these obvious assumptions described above, it would have been reckless to have been driving around or parked up on the streets of Vallejo for approximately 40 minutes after the attack. He would have been right to conclude this, because a limited description of him and his vehicle was given to officers by Michael Mageau at the crime scene, who broadcasted this information over the airwaves. But the Zodiac Killer couldn't have been sure how limited this description would be. He knew his face was shielded by the glare of the flashlight, but his vehicle was afforded no such protection.
We know that after the payphone call was traced, a responding officer was sent from Blue Rock Springs to the payphone to secure it for fingerprint testing, so it is logical to conclude that this is where the Zodiac saw police talking to the black man. If so, then the Zodiac Killer stil had eyes on that payphone at least 10 minutes after his call to Nancy Slover. Because if the payphone call was traced as early as 12:41am, it would have taken the responding officer from Blue Rock Springs about 9 minutes to reach that payphone, at approximately 12:50am. The longer the trace took, the longer the Zodiac Killer was hanging around the vicinity of that payphone. If the phone call was traced at 12:47am, the responding officer would arrive at the payphone at about 12:56am.
The police may have suspected that a payphone call at 12:40am from Sptings & Tuolumne, when its journey time from the crime scene was only 9 minutes, opened up the possibility the Zodiac Killer could have lived nearby. The Zodiac Killer must also have realized this possibility, so he attributed the presence of his vehicle to the negro male, who Zodiac claimed saw it while walking by the payphone at 12:40am, and who at 12:50am (or later), Zodiac claimed he believed, had given the color of his vehicle to the police. Even if the police were not told by the negro male he had noticed the vehicle of the man in the payphone, the accuracy of the negro male's description by Zodiac (if true), would have added validity to the Zodiac Killer's claims his vehicle was present. Another reason why the Zodiac had to ensure his description of the black male was accurate, was because if this information couldn't be verified, the rest of his story loses validity. The Zodiac Killer, in his August 4th 1969 letter, was effectively telling police he was still present near that payphone when they responded to it. He was nearby, and had hung around the area after ending the call with Nancy Slover. By claiming he was still in his vehicle during and after the payphone call, he was suggesting to the police that he had the capability to travel anywhere. But everything described in the first part of this article, should tell you that this may very well have been a lie. His vehicle was never at that payphone - and the real negro male was the conduit for this deception
