THREE UNACCOUNTED FOR BULLETS AT BLUE ROCK SPRINGS?

4/29/2024

 
PictureClick image to enlarge
A while ago I had a discussion with Thomas Horan on the YouTube channel of Ross Geraci called Planet X Filmworks, in which Thomas claimed that Michael Mageau was shot four times while in the backseat of Darlene Ferrin's Corvair and was never in the front seat of the vehicle. Here is that part of the discussion. Thomas also claimed that ten bullets had been fired (and therefore ten casings must have been ejected). Even though only nine casings were detailed in the police report, I will go with the notion that ten bullets were fired into the Corvair and show how it is impossible (even with an extra bullet) that Michael Mageau was shot while located exclusively in the backseat of the vehicle. 

The autopsy report clearly details 5 entry wounds to the mid-axillary and posterior-axillary line of Darlene Ferrin's right side. This means that 5 bullets entered the right side of her body. If Michael Mageau was shot four times in the back seat (because he had 4 entry wounds), this means that there is a total of 9 entry wounds and 9 bullets fired so far. We now have one bullet remaining (to complete the ten shots fired) to produce 4 entry wounds and four exit wounds to Darlene Ferrin's right and left arm, which again was detailed in the autopsy report here (or see below). Thomas Horan's claim of Michael Mageau being in the backseat throughout is therefore impossible from a ballistics standpoint. It's cannot happen with ten shots, never mind nine.

​The reason Darlene Ferrin had 9 entry wounds and 7 exit wounds is because the two shots fired at Michael Mageau in the front seat, passed through his body and entered Darlene Ferrin. They were two of the bullets that entered her right side, producing 5 entry wounds to her torso. Add these 5 entry wounds to the 4 entry wounds in her arms and we have a total of 9 entry wounds. Of the 5 entry wounds to her torso, 3 exited her body on the left side. Add these 3 exit wounds to the 4 exit wounds in her arms and we have a total of 7 exit wounds. Michael Mageau had to be in the front seat during the initial part of the attack to produce the wounds of Darlene Ferrin noted at autopsy. Anybody telling you otherwise is just plain wrong. 

Picture
Above is page 20 from the Blue Rock Springs police report detailing the removal of two "slugs" from the inside of the vehicle, including the seat where Darlene Ferrin was positioned (driver side), and the left hand door. Two bullets remained in Darlene Ferrin's body. One bullet remained in Michael Mageau's left thigh. One was discovered by his person when lying outside the Corvair (that exited his body in the back seat and was trapped in his clothing until he vacated the vehicle, where it fell onto the parking lot). This means that a total of six bullets are accounted for. Where are the other three bullets? By knowing where these three bullets ended up, could shed light on whether Darlene Ferrin was shot first and whether her hands were on the steering wheel when the Zodiac Killer began firing that morning. There was an entry wound 3.5 inches above her right wrist and an entry wound 2 inches above her left wrist, strongly suggesting her wrists were in alignment with one another when the Zodiac Killer took his first shot (with Darlene possibly holding the steering wheel). As she turns away with her right arm coming across her body, the second shot is fired. The approximate images below brings to life this concept. If anybody can shed light on these three remaining bullets, feel free to post in comments.   ​

There were 9 entry wounds and 7 exit wounds to the body of Darlene Ferrin noted at autopsy. There were 2 bullets recovered from her torso at autopsy. The right arm has 2 entry wounds; one is 5 and 1/2 inches above elbow on right lateral side, fracturing the humerus shaft and exiting anteriorly and medially 1 and 1/4 inches distal to the elbow. The second entry wound to the right arm is behind the forearm, 3 and 1/2 inches above the wrist (exiting opposite side).

The left arm has two entry wounds; one is medially located in the upper arm, 3 and 1/4 inches above the elbow and exiting the opposite side. The second entry wound is located medially on the forearm, 2 inches above the wrist, fracturing the radial and ulnar bones, and exiting above and laterally at 3 inches above the wrist.

[4] Bullet passes through 4th rib, right lung, the anterior shaft of right 2nd rib, where it was recovered in the subcutaneous tissue at autopsy.
[5] Bullet passes through right shoulder, the anterior chest wall to the anterior margin of the sternum, level with 4th ribs, and exits the left side of the left breast, just above the nipple.

If Darlene Ferrin had been shot first, one might expect Michael Mageau to lean to the left away from the shooter and towards the chest region of Darlene Ferrin, with his head positioned lower. The bullets that struck his jaw and right shoulder region exiting his body and striking the right torso of Darlene Ferrin, who would be also turning away from the shooter at this point. If Michael Mageau had been shot first, one might expect the bullets that exited his jaw and right shoulder to have impacted Darlene Ferrin at a higher position on her body.

Good stuff Richard! The succession of shots may be open to interpretation but do you think the first shots had to be at (and through) Michael or Is it possible that he first shot the driver through the arms?

Richard

Being that Darlene had the ability to drive away and scupper his plans, I suspect she received the first 2 shots. The natural reaction of Michael at this point is to turn away from the gunfire, who then received the second two shots, followed by a third shot into Darlene's right side. Then Michael leaps over into the backseat, realizing it's his only refuge.This is followed by the final two shots to each victim. If Michael was shot first, I suspect there is less chance for Darlene's wrists and arms to be aligned to create the 4 entry and 4 exit wounds. Unfortunately Drew, bullets don't contain a time stamp, so we can't know for certain the exact order, but the wounds to her arms and the vehicle being in gear, with the handbrake off suggests to me a readiness to drive away. They couldn't know for certain that this person approaching their vehicle was a copper - and with the previous telling of a vehicle sitting to their left side only minutes earlier with the headlights doused - this should have made the couple understandibly wary. What percentages do you apply to Darlene being targeted first Drew and why? I tend to go with a 90% chance Darlene received the first shot that morning. As with the Cheri Jo Bates and Betty Lou Jensen autopsies, it's crucial to examine them in context to the crime scene and ballistics.

I've added a total of 3 extra images to help explain the thinking behind this.

Drew

If Zodiac hadn't claimed in the Aug4 letter to have fired the first one at Michael I would think the Darlene would be the target, as she represented the risk of thwarting the entire affair by driving away, and the positioning of her hands on the wheel strongly suggest that she was just about to do so. Additionally, I don't know if Michael could have avoided a fatal blow if he was truly shot first. Zodiac makes it sound like Michael lunged into the back during the initial flurry of shots but it seems to me that unless the shooter had pivoted towards Darlene for a moment he would not have had the chance. I think there is a high chance Darlene was shot first and that Zodiac may have been mistaken in his letter.

Richard

"The boy was origionally sitting in the front seat when I began fireing. When I fired the first shot at his head, he leaped backwards at the same time, thus spoiling my aim".

In this statement Zodiac said that Mageau was in the front seat when he began firing, not necessarily that when he began firing it was at Michael. Also, just because Zodiac stated "When I fired the first shot at his head", doesn't imply this was the first shot that night, only that it was the first shot aimed at Michael.

Drew
4/30/2024 08:27:31 am

Yes, good point! If the alternative is that the first shots went through Michael and into Darlene I'm not sure her hands would still be on the wheel. My vote is Darlene was shot first. Great detailed work here Richard

Hi! It's great news that the comments section is open again.

I must say that I do not agree with Mr. Horan at all in regard to where Mageau first sat while the shooting started. In his recount he clearly says it, he was in the front seat, so I have no idea why Mr. Horan floats this claim.

It is also well established that the first shot aimed at Mageau's head, following the MO at LHR, where the Zodiac fired a close range shot into Faraday's head. It is clear that he attempts the same here, but that he fails to achieve his goal to eliminate the male victim quickly.

He then may have started to fire at Darlene.

Richard
4/30/2024 03:54:18 am

I certainly cannot say for certainty that Michael wasn't targeted first Altuğ, but yes, it is with little doubt David Faraday was shot first at Lake Herman Road. Faraday was the greatest threat to Zodiac, being the male, so the question that has to be asked at Blue Rock Springs is, who was the biggest threat to Zodiac's plans. Was it Darlene Ferrin who could have driven away, or Michael Mageau who was a sitting duck in a vehicle. The Zodiac clearly switched tactics from LHR to BRS by keeping the couple in the vehicle, thereby reducing the risk from the male. I won't challenge the notion of it being well established that Mageau's head was targeted first, but just because most people think this to be the case doesn't make it true. However, I don't discount the idea Altuğ. Most people believe that Betty Lou Jensen was running directly away from Zodiac at Lake Herman Road when she was hit 5 times in the back, but the autopsy report shows that this is almost certainly not the case. The dynamics of the attack and order of the shots at BRS is less certain, so I still remain open minded.

Sometimes ''context'' offers the explanation ?

It may be difficult to prove, but the Zodiac was targeting Darlene, and Michael just got in the way, both figuratively and simply being there.

The Zodiac went for Michael first, so as to be able to concentrate on Darlene. Rage, rage, rage on Darlene. Michael was only there, to assist the picking up of a bag of weed, for Darlene - for the rest of her evening's social event. He and is brother both had a crush on Darlene, and competed to help Darlene out, if ever she needed a favour.

That's one perspective, anyway. It was the three who arrived soon after, that were coming with the bag of weed for Darlene. They knew Michael. They were so lucky, they didn't get hurt themselves..

Richard

Even though some people believe Zodiac targeted Darlene, I think it is impossible to prove at this juncture Rubislaw. I doubt I could prove it if I spent 16 hours a day for one year researching it. If somebody has 100% proof I'm all ears. Unfortunately, after 55 years it almost certainly doesn't exist.

Philosophically, that makes good sense, Richard.

The police reports that have been published on events at Blue Rock Springs are ''sketchy'' at best - in comparison to say, autopsy details that you document and present very well, here.

Back to the ''Did Zodiac know Darlene debate'', I think the investigators, and what is known beyond reasonable doubt, is well-understood with the entity that counts - CA DOJ for prospective prosecution.

Suffice, I am confident that Zodiac was after Darlene, having lost his patience in believing that Darlene ''wasn't'' about to run to the cops, with what Zodiac believed she might know.

The reality ? She wasn't about to run to the cops and, if she had any suspicions, couldn't be sure anyway. But, Zodiac was no longer convinced - now operating out of fear that he would be rumbled.

So, so tragic.

I think there are several facts here that are overlooked.

1. Mageau tells police he sat in the front passenger seat. He tells in lenght how he threw himself into the backseat when the firing began - why would anyone claim he was in the back seat when the firing began?

2. There are no drugs in the evidence - why would anyone invent a drug deal scenario?

3. Mageau explains how immediately with the beginning of the firing he felt pain in his neck, which tells us he was the target of the first shot, which was an attempt to an executioner style point blank shot - why would anyone say that the actual target was Ferrin?

4. The Z approaches the car two times. First he parks behind the left of Ferrin's Corvair, assuming that the driver is the male. He realizes that's not the case. He drives away, then comes back, and parks to the right of the Corvair, where the male sits. Again, an indication that fits his LHR MO: get rid of the male first. - why would anyone think his intention was to kill Ferrin first?

I think it makes no sense the go totally against what witnesses say and what reports show.

Altug Isigan
5/1/2024 04:18:07 am

Not that I am against any constructive and positive discussion, but I think in order to proceed meaningfully we should stick with some facts so that we know the area within which to speculate. I think Horan and some commenter here speculate in a way that violates the basic logic that testimony and evidence reinforces, so we arrive at a lot of unfounded, even wild hupotheses imho.

Hi Altug Isigan.

Certainly not my intention to sound controversial, and I'm not insinuating that these three, !7 year old Jerry, 17 year old Roger and older Debra were anything other than casual pot peddlers.

But, if you read the ''to date'' report on their claimed account - it doesn't all sound totally convincing. None of them stayed with two badly injured victims. All went back to Jerry's house, before deciding to phone the police.

Maybe they were ''young & scared'' (?) - but they did at least alert the cops - seemingly in their own time.

Rubislaw32 link
5/1/2024 05:21:55 am

'' casual pot peddlers'' ? At one time it was quite common - young folk peddling small amounts. Just enough to pay for their own usage. And no intentions of breaking the law in any other way.

Rubislaw32 link
5/3/2024 02:14:47 pm

Yes - my take on Jerry, Debra and Roger is : The police would have just wanted to establish all that the three could give, in terms of describing the car they encountered coming in the opposite direction (Zodiac's ?).

''Behind the scenes'', the police would have established that Jerry was a known associate of Michael ( It was Jerry who claimed that he initially wanted to stay behind with badly injured Michael).

The police would have just left it at that - satisfied that the three were on their way to deliver a small quantity of weed to Darlene & Michael..

Altug Isigan
5/4/2024 04:30:40 am

Let's assume for a moment that this is the case. My question is:

What does it reveal about the Zodiac? Does it for example bring a new perspective on his victimology (he was not only after necking couples, but they also need to be pot peddling youngsters)?

It would imply he knows that marijuana is involved. How would he know that? Does he observe the trade in town and singles out the pot peddlers to execute them? Sure that would mean more victims, when you think about how many pot peddlers are around. More importanly, his first two victims didn't do drugs.

If he observes his victims, how do we explain Napa? Cecilia comes from LA over the weekend, Brian comes from Angwin. How would the Z know about two pot peddlers who live 400 miles away from each other, and decide to kill them in Napa?

I appreciate asking questions and working theories. But I think hypotheses should be based on information in the report and on a certain level of plausibility. I don't see it here, and I believe it does not help to establish the Z's profile in a clearer way.

''Deduction'' ? Granted it is in itself a controversial word. Sometimes only limited to what can be deduced from limited information. And sometimes nothing at all.

There are countless examples (though not always confirmed as such) where the Zodiac appears to have been stalking or spying. With the BRS scenario, it appears that he may well have been stalking Darlene that evening - primarily by ''car recognition'', in the knowledge of a car she was using at the time. Darlene had only just acquired her driving licence, and was borrowing her father-in-law's car. We know this from family members. On the morning before her death, she was spotted with a yet-identified man, who appeared to be helping her with her faulty car (Zodiac ?).

If we take it to the nth degree, it could be argued that we can't be sure of anything at all. But, unless we start making ''provisional at least'' deductions - then we might as well give up, completely.
