To expand ….

Walker worked as a secretary at Space Technologies Laboratories in El Segundo CA, near LAX, in a cluster of aerospace companies. It is a federally-funded consultancy involved in satellites. They work/ed with the National Reconnaissance Organization, with an office in El Segundo. The NRO ran/runs the US spy satellite program.

This 1987 LA Times article details the West Coast military intelligence system. It describes the NRO office. It describes Skaggs Island, near Vallejo, run by the NSA and the Navy, where a unit of code experts tracked Russian subs, used radians, and worked with teletype machines. It also says they launched the satellites at Vandenburg AFB, near Lompoc. There are a number of intelligence installations close or fairly close to Zodiac activity.

So with these details in mind …

Do I think Walker was killed by someone she knew?
Was that a person a co-worker/work associate?
Was that person involved in the West Coast intelligence network?
Was that person connected to Skaggs Island?

It’s speculation for now. But it would make a lot of sense.

Seagull’s posted upthread about Walker being found covered in a blanket and that often happens when the killer knows the victim. Also, she was chatting with the man at the scene of the car wreck.

In the possible Zodiac murders of Domingos and Edwards, Santa Barbara, the victims were also covered with a blanket, which also happened in some of the Midwest Murders, like the Robison family murder.. Of course the use of a disabled car in the Walker case reminds one of the use of disabled cars in the possible Zodiac crimes Bates and Johns.

The suspect in the Joyce Walker murder was seen walking with a limp. At least two people described Zodiac having an unusual walk, possibly a slight to moderate limp of some kind. Officer Fouke said the man he saw at the Stine crime scene walked with a "shuffling lope", but further described it as a "lumbering gait…a semi-limp". A girl at Lake Berryessa said that a man watching her and her friends, who may have been the Zodiac, did not exactly have a "limp", but then described something very much like a limp, saying she observed he "favored one leg over the other".

Good work by replaceablehead and Nick, no Nora. It is very interesting that Joyce Walker worked for Space Technologies Laboratory, and that company was involved in spy satellites. Nick, no Nora explores these facts in that they might pertain to a possible POI being found who worked for one of these companies or in this field of high tech, weapons and satellites. For me it is most interesting when you look at a pattern of possible Zodiac Killer and Midwest Murders cases involving victims whose fathers worked for companies involved in high tech, computers, weapons and aircraft / satellite surveillance.

Cheri Bates father worked at a facility for testing naval weapons, that included missiles. Mr Robison had announced a plan to remove forestry near airports and build computerized warehouses for the airplane cargo industry. Nr Bricca worked as a chemical engineer at Monsanto.

Charles Percy, the father of murder victim in suburban Chicago on 9/18/66, Valerie Percy, was the CEO of Bell & Howell. They made business machines, the forerunners of computers. They also made cameras, including most of the cameras that were attached to US military aircraft.

Joyce Walker was killed on Thanksgiving in 1964, which was on 11/26/64.There were other Zodiac, Midwest Murders and College Girl Murders that happened around Thanksgiving. Of course Cheri Bates was killed the day before another Fall holiday, Halloween. The man who killed Cheri Bates outside the college library likely mailed the confession letter on 11/28/66. Betsy Aardsma was killed on 11/28/69 at the Penn State college library, with a witness picking from a photo lineup a picture of a Zodiac Killer and Midwest Murders suspect. And 12 years later, Joan Webster, Harvard student, went missing on 11/28/81, last seen in the company of an unknown bearded man, and was later found murdered.

Joan Webster’s father used to work for the CIA, and in 1981 was a Vice President at IT&T, of the military technology and weapons division. IT&T also did a lot of work for the CIA, and was exposed in late 1970’s Congressional hearings as having in the early and mid 1970’s helped the CIA overthrow Allende in Chile. IT&T having set up the communication networks in Chile, a clear asset to the CIA for spying.

We must consider Joyce Walker working at Space Technology Laboratories, a company involved in the space program and spy satellites, and the other victims or victims fathers links to high tech, computers, weapons and satellites that Nick, no Nora and I show. It is all particularly relevant to a Zodiac and Midwest Murders suspect who FBI files said had a noticeable limp, as did the killer of Joyce Walker. And this suspect hated technology and computers, had a legitimate reason to have a grudge against the CIA and had a particular paranoia about, obsession with and hatred for airplanes and for aircraft and satellites he felt the government used to spy on citizens.

You can get more info on these high tech links and this POI at viewtopic.php?f=102&p=84652#p84652.

And for more information generally on Space Technologies Laboratory, missile and satellite programs and links to the Walker and Bates cases, see viewtopic.php?f=37&t=5211&start=20

We are getting a little off track. I only mentioned the limp because there are witness reports that both the Walker murder suspect and the Zodiac Killer walked with a noticeable impediment of some kind. It is not all that important. certainly not as important as the other characteristics that witnesses of both the Walker murder suspect and the Zodiac Killer described. Such as being 5’8" to 5’10" in height, being around 160 pounds in weight, both described as having short light brown hair, and the very interesting but debatable possible matches and similarities in MO and victim or victims father’s employment.

Some points to consider are these: Based on the witness descriptions, is it even possible that the man who murdered Joyce Walker and the Zodiac Killer could be the same man? And do any of the MO and victim elements of the Walker murder share any MO and victim elements with possible and confirmed Zodiac crimes?

Consider the following witness descriptions and wanted poster descriptions of the primary suspect in the Joyce Walker murder:

And the witness descriptions and police wanted posted for the Zodiac Killer:

Mageau said 5’8" – 5’9", 160 pounds, 25 to 30 years old, light brown hair. Kathleen Johns said about 30 years old and 160 pounds. The SFPD wanted poster says 5’8" and brown hair, with a possible characteristic that lightens it (a red tint).. The poster says possible age of 35 to 45, and the sketch on the right looks looks a man 35 to 45 years old. The sketch on the left looks more like a man age 25 to 35 years old. I would add that both the Joyce Walker suspect sketch and the left Zodiac Killer suspect sketch depict a man with "average" and "normal" looks, as one of the teen girls at LB described the man she saw watching her and her friends at the lake.

Both have large foreheads, strong jawline, jutting chin, effeminate lips. Considering this was the the 1960’s, when longer hair, facial hair and generally more scruffy and sloppy looks were in style, I would also say that both the Walker suspect sketch and the Zodiac Killer suspect sketch depict a man with a clean shaven, neat short hair look, and both have smooth faces.

Trained observer SFPD Officer Fouke said the 250 pound Allen weighed about "100 pounds" more than the Zodiac he saw that night in SF. (Source: Interview of Fouke in the film "His Name Was Arthur Leigh Allen" attached to the DVD of the David Fincher film "Zodiac". Go to the 31 minute mark of the documentary.)

Thanks to Richard Grinell and Traveller1st, you can now click here to see just the relevant part of the documentary:

https://www.youtube.com/watch?v=YJYvHJlt-gg

Which means the trained and experienced police officer Fouke is likely saying the man he saw at the scene of the Stine murder weighed about 150 to 160 pounds.

As Tom Voigt points out, I am making an assumption, but basedin typical police procedures I think a reasonable assumption, that Officer Fouke was likely told by the detective who showed him the picture of Allen what was Allen’s weight. As they should have had a copy of Allen’s drivers license in their Allen file.

Absent that, having seen a picture of Allen, Officer Fouke would likely have asked what was Allen’s weight. But if he did not, having seen a picture of him I would think it very likely he would have estimated Allen’s weight. In which case he likely would have correctly thought it to be around 240 – 260, but it is possible he thought Allen was heavier, maybe 260 – 270, and possibly, though I doubt it,a wrong estimate of 300 pounds. In which case his saying that Allen weighed 100 pounds more than the man he saw likely puts Zodiac at 150 to 160, but could have put Zodiac at 160 to 170, and though I doubt it, possibly as much as 180 to 200 pounds.

But for my overall comparison of Zodiac witness descriptions to Walker suspect descriptions, I also use the Mageau and Johns estimates of the Zodiac’s weight at 160 pounds, their age estimates of 25 -30 and 30, and Mageau’s and the SFPD’s wanted poster estimate of 5’8" – 5’9" and 5’8" – 5’10".

Considering those estimates match those of the Walker suspect, and the general matches between the Walker suspect and the Zodiac Killer on "short light brown hair", age, and other factors, I conclude that it is certainly possible that the Walker suspect could be the Zodiac Killer. I also mention that witnesses to both the Walker suspect and the Zodiac Killer gave descriptions of them having a walk that was identified as a limp.

The possible matches and similarities in MO and victims or victim’s father’s employment I and some others find interesting , but it is more speculative. And likely to be of great interest only to the much smaller group of Zodiac researchers who have some prior knowledge of and interest in the Midwest Murders and College Girl killings I have written about elsewhere.

Joyce Walker suspect witness descriptions and police wanted poster descriptions, you have a man in 1964 about 5’8" to 5’10", 160 pounds, 25 to 30 years old, with short light brown hair.

Zodiac Killer witness and police wanted poster descriptions, you have a man in 1969 about 5’8" to 5’10", 160 pounds, either being 25 to 35 years old or perhaps 35 to 45 years old, with short light brown hair.

I would add that both the Joyce Walker suspect sketch and the left Zodiac Killer suspect sketch depict a man with "average" and "normal" looks, as one of the teen girls at LB described the man she saw watching her and her friends.

Both the Walker suspect and the Zodiac Killer suspect have large foreheads, a strong jawline, jutting chins, effeminate lips. Considering this was the the 1960’s, when longer hair, facial hair and generally more scruffy and sloppy looks were in style, I would also say that both the Walker suspect sketch and the Zodiac Killer suspect sketch depict a man with a clean shaven, neat short hair look, and both have smooth faces.

I would say that based on the descriptions of height, weight, age and hair style and color, it is definitely possible that the Joyce Walker murder suspect and the Zodiac Killer could be the same man.

What about MO & victim elements in the Walker murder and possible and confirmed Zodiac Killer cases?

In all of the confirmed Zodiac cases, no victim was attacked at their apartment. In the possible Z cases of Hakari and Lass, they likely were attacked or abducted at their apartments. In the possible Zodiac case of Bennallack, she was murdered in her apartment.

Joyce Walker was murdered and covered with a blanket on 11/26/64. In the possible Zodiac murders of Domingos and Edwards, Santa Barbara, on 6/4/63, the victims were also covered with a blanket. This also happened in some of the Midwest Murders, like the 6/25/68 Robison family murders, were Mrs Robison was covered with a blanket.

Joyce Walker was stabbed 50 times by a long knife. This type of frenzied overkill is also seen in the confirmed Zodiac crime of the repeated stabbings of Celia Shepard by a long knife, as well as in the possible Zodiac crimes of the Midwest Murders, were Valerie Percy was stabbed repeatedly with a long knife , the Robison mother and daughter were stabbed repeatedly and Mrs Linda Bricca was stabbed over 20 times by a long knife.

Of course the possible use of a disabled car in the Walker case, with both right tires flat, reminds one of the use of disabled cars in the possible Zodiac crimes of Bates and Johns. But in the Walker case it is not clear from the newspaper articles if the vehicle was disabled by the flat tires first, before getting in a possible accident, or if the accident came first and led to both right tires becoming flat.

The suspect in the Joyce Walker murder was seen walking with a limp.

At least two people described Zodiac having an unusual walk, possibly a slight to moderate limp of some kind.

Officer Fouke said the man he saw at the Stine crime scene walked with a "shuffling lope", but later he further described it as a "lumbering gait…a semi-limp". A girl at Lake Berryessa said that a man watching her and her friends, who may have been the Zodiac, did not exactly have a "limp". But then described something very much like a limp, saying she observed he "favored one leg over the other".

It is very interesting that Joyce Walker worked for Space Technologies Laboratory, and that company was involved in computers, missiles and spy satellites. Replaceablehead and Nick, no Nora explore these facts in that they might pertain to a possible POI being found who worked for one of these companies or in the field of computers, high tech, weapons, missiles or spy aircraft/satellites.

For me it is most interesting when you look at a pattern of possible Zodiac Killer and Midwest Murders cases involving victims whose fathers worked for companies involved in high tech, computers, weapons and/or aircraft/satellite surveillance.

Joyce Walker worked at Space Technologies Laboratory, work which involved computers, missiles and spy satellites.

Cheri Bates father worked at the Naval Ordinance Laboratory for testing naval weapons, which included missiles. Mr Robison had announced a plan to remove forestry near airports and build computerized warehouses for the airplane cargo industry. The Bricca family was murdered on 9/27/66, three years before the Zodiac killed Celia Shepard on 9/27/69.Mr Bricca worked as a chemical engineer at Monsanto.

Charles Percy, the father of the murder victim in suburban Chicago on 9/18/66, Valerie Percy, was then running for the US Senate, but was the former CEO of Bell & Howell. They made business machines, the forerunners of computers. They also made cameras, including most of the cameras that were attached to US military aircraft.

Joan Webster’s father used to work for the CIA, and in 1981 was a Vice President at IT&T, of the military technology and weapons division.

Replaceablehead and Nick, no Nora did some very good work in taking a fresh look at the Robison case of 6/25/68 and the person who wrote to the newspaper with inside knowledge of the crime that only the killer would know, who called himself Zodius, six months before the man who called himself Zodiac did his first confirmed killing on 12/20/68, and later wrote to the SF newspaper with inside knowledge of that murder and a murder on 7/4/69. Both Zodius and Zodiac were described as having a telephone voice of speaking in a monotone with pauses. In both cases the killers used .22 Super X ammo, with police in both Michigan Zodius 6/25/68 and California Zodiac 12/20/68 determining the gun used had six right hand twists and groves, with the most likely weapon being a JG Higgins pistol. They also explore the possible similarities in the Walker and Bates cases to the Robison, Percy and other Midwest Murder cases, the possible pattern being victims fathers who worked in high tech, computers, weapons, missiles and aircraft or satellite spying.

"Trained observer SFPD Officer Fouke said the 250 pound Allen weighed about "100 pounds" more than the Zodiac he saw that night in SF."”

You’re assuming Fouke pegged Allen as weighing 250.

Perhaps Fouke pegged Allen at weighing 300. Or perhaps Fouke pegged Allen as weighing 350. Not to mention that Fouke’s own report stated the suspicious man weighed between 180 – 200 LBS with a medium-heavy build. And that report was from November 1969 and not after he grew elderly with health and memory problems.

Also, this "trained observer" stuff is a cliche. One doesn’t develop superpowers just because they managed to graduate from the police academy.

ALA doesn’t look 300lbs or more to anyone with a brain.

The above sketch, also looks like the three girls sketch from LB.

The limp was something that he could have faked and used at his convenience. Or it could have been due to a temporary injury. If so, that would partly explain how the Zodiac has escaped detection all these years.

ALA doesn’t look 300lbs or more to anyone with a brain.

That would be an assumption.

Do I need to explain to you how assumptions work?

The limp was something that he could have faked and used at his convenience. Or it could have been due to a temporary injury. If so, that would partly explain how the Zodiac has escaped detection all these years.

So you think Zodiac might have escaped detection all these years by possible faking a limp? For real?

No, I did not say that at all!

I suggested it as a possibility. He either had a limp or he did not. If he had a genuine limp, it could have been due to a temporary condition, such as a sprained ankle or knee problem.

Or he could have been faking a limp as part of his disguise. It would not be that hard to do.

OTOH, he could have had a physical problem that caused a permanent limp.

However, if he had a limp due to an impairment, wouldn’t that eliminate the possibility that he had served in the military? Do Merchant Marines have to pass a physical?

Or he could have been faking a limp as part of his disguise. It would not be that hard to do.

Who is he, Long John Silver? What kind of cornball fakes a limp? I suppose he was wearing a one of those dime store Groucho disguises as well.

Look, maybe. But is it likely? No.

We are getting a little off track. I only mentioned the limp because there are witness reports that both the Walker murder suspect and the Zodiac Killer walked with a noticeable impediment of some kind. It is not all that important. certainly not as important as the other characteristics that witnesses of both the Walker murder suspect and the Zodiac Killer described.

For the same kf assumption, let’s say that we’re dealing with the same killer in the "limp" murders …. then It seems like the limp, or walking problem, or what have you, comes and goes. Twice it is described by police (PH and Walker). The other two times it appears to witnesses after the attacks (LB, Maher). But I’m unaware of any victims noticing it. Which make me wonder if the limp is his go-to move when he knows he’s being observed. Particularly by cops. But it might be real, too.

The limp was something that he could have faked and used at his convenience.

What limp exactly? The one nobody noticed until elderly Fouke mentioned a "semi limp" decades letter?

Twice it is described by police (PH and Walker).

Fouke didn’t describe a limp while he was an officer. The "semi limp" quote came decades later.

While Foulke may have initially described the suspect as 150 to 160, All other witnesses described a man much heavier. Also, after Foulke’s scratch memo, the weight on the wanted posted was increased to match other witnesses’ descriptions.

While Foulke may have initially described the suspect as 150 to 160…

He didn’t, though.
