I think it would have made him mad that those two, average, every day, normal schoolteachers solved his cipher in only two days.

Psychologically, this would help him restore his wounded ego, and add to the public's intrigue. He wanted everyone trying desperately to solve the ciphers. He wants to be seen as mysterious and brilliant

[@frankdrebin1023]

I used to feel this way. However, the FBI and other code breaking professionals seem adamant his unsolved ciphers do contain msges. I'm not bright enough to explain why, but there's some good videos on youtube regarding the subject. And, not made by fruitcakes. Ironically, the teacher that solved his cipher shared your last name. Also, a cipher key arrived at the Vallejo PD a day after the Harding's solved it. It's thought to be authored by Zodiac, so, he wanted it solved.

Disappointing, it will be another sarcastic taunt at police, or something like "SLAVES BY GUN, BY KNIFE, BY ROPE, BY FIRE".

Sadly, after reading tons about this case over the years, my conclusion is that the police are never really as smart as they want you to believe they are. The FBI have brilliant people, no doubt, but they are rarely involved early on in cases like this, or at least, years ago they weren't when it counted, which is tragic.

[@leemoore9933]

They want to take the short cut more often then they care to admit at times.

[@mp1201]

Good points. As the FBI has to be asked to help with investigations by the police, helps to explain why the FBI are not involved at an early stage. That is very unfortunate as the FBI have more experience and resources. Which also speaks to your point about police. The focus needs to be on the victim. Asking for assistance from all agencies is the smart thing to do.

Before he could be identified, the Zodiac successfully ran for office, becoming a US Senator from Texas. This way, he could use his political influence to shut down any investigations that might lead back to him

[@kicknadeadcat]

I believe the main suspect died in jail, put there from other charges. Nothing could be proven but the killing stopped. I lived two blocks from where son of Sam made his last kills, two people in Brooklyn. The neighborhood was frantic. They caught him because of those shootings. He was parked in someone’s driveway and they called the police that ticketed his car. Good police work found a ticket was given to someone who’s car was registered in the Bronx that morning. They found the car and looked in the backseat and saw weapons. Waited for the owner to show up and they caught him. His words to the cops were “ what took you so long “. Very creepy times......

[@mikemck4796]

I have a possible theory on the “bad grammar” component. As a child in grade school I was hospitalized for behavioral issues. This was at a time when I would have been taught hand writing, and grammar. That was likely the a cause in me having bad spelling/grammar. In the hospital, the school work was mostly math based, and I wound up excelling there. So much so, later on I was moved up grades, and graduated HS two years early. My writing skills are not terrible by average standards, but are when compared to any of my other academic skills. Plus, I have spell check.

[@robharms1659]

Interesting. So is your kill count higher or lower than 5?

[@TheeAmethystEmpress6589]

Very intriguing point. There were many long-term childhood hospitalizations in the first part of the century. Your theory is quite valid. I like it.

That is very interesting, because of course it’s easy to imagine the Zodiac might have been in some sort of institution as a child or teen.

Great point Mike! When I had to do a mentorship in college, I sat in real job interviews with my mentor as he interviewed perspective hires. One gentleman who came in was a mathematical genius PHD but his writing was awful. My mentor mentioned this to him and the man responsed that his PhD dissertation was all math based and therefore he didn't need to write. He didn't get the job, by the way.

[@mikemck4796]

Iron Fist Films I’ve also found many of us who are math and logic based, don’t really give much importance to writing. To purpose should be to convey the proper information, not make it pretty or technically correct. Spending mental resources concerned about such things seems like a waste.

I grew up in the area where he did the killings. Back when I was in grammar school, he sent a note to the police indicating that he might target children from school buses. So we had police cars following our school busses. Weird.

[@teeshirtandjeans84]

Dr Grande looks like the sketch of the Zodiac Killer. LOL the side-by-side cracked me up! Good video, as always!

[@TheGbelcher]

Dr. Grande, I love all of your videos and your perspective on mental health issues. Can you pls do a video on the series “Married At First Sight?” It’s a series where three “experts”, all of whom have degrees and licenses in relationship and/or sex therapy, convince ppl to marry complete strangers... at first sight. I’m concerned that the show prioritizes drama over mental health and I think the “experts” have to be in violation for deliberately putting ppl in embarrassing and dangerous (sometimes physically dangerous) circumstances. Your perspective on this popular show would be appreciated.

[@blazefairchild465]

I hope this show is all fake. I saw it once & felt it cringe worthy. How can people volunteer for marriage. Remember the Dating Game serial killer ? The girl did back out of the date ,but he was the contestant she picked. Thank goodness she had second thoughts !

[@kate2create738]

As someone whose mother watches the show, I would greatly value your thoughts on it. Let's just say it's not a show I'd volunteer to watch with her.

[@Mysikrysa]

Wait, what? There´s show where "experts" manipulate random people to marry other random people? It must be fake. Even the most desperate and lonely people would have some dignity to refuse this. It´s like medieval forced marriages. It can´t be legal in our society.

[@jamesocallaghan898]

I am skeptical that the Zodiac targeted women in particular here is why: When he tied up Bryan Hartnell and Cecilia Shepard and stabbed them the woman was stabbed more than the man but...they acted very differently when stabbed. Bryan played dead while Cecilia thrashed about and made as much noise as she could until the end. It could have been this difference in behavior that caused Cecilia to be stabbed more frequently and not the fact that she was a woman. When he attacked Darlene Ferrin and Michael Mageau the woman died and the man survived but...He shot Darlene five times and Michael four times (not much of a difference and Michael was shot first) the reason why Darlene died is because the bullets that struck Michael went through him and struck her too so she got a double dose. Therefore I don't see how you could deduce that he had a greater desire to kill the woman during this incident. When he killed David Faraday and Betty Lou Jensen it is true that Betty was shot more times than David but...David was shot at point blank range while Betty was shot from d distance while she was running away. Again there are valid alternative explanations as to why more force was seemingly used on the female other than the Zodiac had it in for women.

[@danarodriguez8735]

I completely agree with your assessment. I don't think he particularly set his sights up to murder the women any more than the men. Great view of the case!

[@whatdoyoulivefor735]

Agreed!

[@mysteryjunkie9808]

Yeah i think it's just the fact two of the men lived vs none of the women living. Which as you pointed at can be easily explained. I think he was targeting couples.

[@-gohu-]

exactly. i was surprised to hear him say that. if he wanted to only kill women, why did he target couples and a single man? he'd just target women, period. it makes no sense to me.

In any event, please keep it up because I look forward to watching everyday.

His best analysis yet. I've always been very interested in the Zodiac Killer and have read the book as well as watched the two movies about the Zodiac. Very interesting.

Could you do a video on Anxiety/Panic Disorder? I see a lot of social anxiety but not GAD or Panic Disorder. I'd love to hear your takes on these, their differences, and if one could be diagnosed with both, if they coincide. Love the way you discuss mental illness. Thanks for what you do!

I did point out that there's a lot on social anxiety in my original comment and didn't find any on GAD. I appreciate the work you did finding the one on GAD. I must've stopped searching after year 3 I think.

[@KoreaMojo]

Why is death the ultimate insult for a narcissist? Is it an insurmountable proof of the delusional base of their grandiosity? Is it because no matter how entitled to everything they are, they cannot obtain assured immortality? Does it challenge their false identity's strength and uniqueness by triggering the commonplace fear of the unknown? I'm offering my own conjectures but I can't be too confident yet I have noticed this idea of death and aging being a huge trigger.

[@frankenz66]

At the worst, at some twisted level, maybe they believe the whole world literally ends when they die. So they must always go on. Them being the ultimate center of it. Everyone/ thing else is just fluff for them to use and abuse.

[@ShunyamNiketana]

The narcissist can't die. Admission that they are mortal would cause the whole hollow structure to collapse. The world lives on; the narcissist is gone and soon forgotten. And that runs counter to any narrative of grandiosity.

[@nikkilea5632]

It’s the one thing they can’t manipulate or have any control over.

[@carlmarburger7513]

I've read quite a few books on this topic. The one thing that I found astounding was all the suspects the various law enforcement agencies went through in the search for the Zodiac. Each suspect was a very disturbed, maladjusted individual that should not be walking the streets, but some thing or a number of things would conclusively rule them out as the Zodiac. So, these people are still out there among us. There are a lot of very messed up people out there we pass every day and have no idea.

[@catylynch7909]

What memories this brings back! I live in San Francisco, and had just begun work at KGO Radio, in May of '69. Our radio morning talk show host, also hosted a program on KGO-TV, earlier in the morning. It was on that program that "the Zodiac," had requested a conversation with Melvin Belli. Mr. Belli was not shy about public appearances, and agreed to appear on the program. To my knowledge, it was never determined if the man who called the program was, indeed, "the Zodiac." Whoever it was, called the program several times, but would speak for only a few minutes, before hanging up ... sometimes after making a screaming sound ... only to call back, again. He said that he wanted to meet with Mr. Belli, at a destination in Daly City, which is immediately south of San Francisco. He specified that no police were to be at the destination. (Yeah, RIGHT!) Every media outlet in the area, immediately, dispatched a "news car/truck" to KGO, to follow Mr. Belli, and Jim Dunbar, to the location. We were all sure that those vehicles were loaded with San Francisco, and Daly City, police ... along with representatives from every other applicable law-enforcement branch of government. Not surprisingly, the "caller/Zodiac," never appeared. I had not ever heard that the calls were traced back to someone who was being treated for a mental problem. However, that would make sense.

[@marcellepesek3038]

Dr. Grande, your insightful analyses are absolutely riveting. Also, I'd like to thank you for speaking proper English, rather than the hodge-podge which passes for a proper language nowadays. People don't seem to realize that this beautiful language is a treasure which has been diluted and messed up in many ways. There are grammatical rules for a reason, as there are traffic laws for a good reason. I realize that abbreviations for texts have also done their part, but it goes far beyond that. Languages may change over time, but there is no reason for us to become sloppy. I'm amazed that even many professional people are adopting this mongrel lingo. It becomes jarring to hear. I'll probably draw negative comments, but for once I wanted to voice my opinion on this subject. Thank you for allowing me to sound off. Please keep those great programs coming our way!

I lived in Napa while the Zodiac was on his crime spree. He killed people at Lake Berryessa, Vallejo and in San Francisco. At the same time there was a copy cat killer called the Golden State killer who was just caught last year. He was in his seventies. So the Zodiac could still be alive. There was also the Trail side killer around the same time. He is in prison and in his 80's.

Great video doc. Just one question; what did you think of the David Fincher movie about the case, "Zodiac"? I think it's his best. And am fascinated with his approach, that is, his movie is not really about the Zodiac case, but obsession. And how obsession affected three lives. The lead detective, a top crime reporter, and a somewhat odd cartoonist, who became convinced he could solve the case, even at the cost of his second marriage.
