When buying a gun Homer Simpson was told there had to be a 5 day background check. He responded to the clerk with, "but I'm mad now!"

Hello Dr. Todd, I am a retired Correctional Officer, I worked with Jennifer San Marco when she was employed at CRC in Norco, Ca. Jennifer originally was employed at Chuckawalla State Prison, Blythe, whereas she was fired for having sex with male inmates. CRC s Warden after a time allowed Jennifer to return as a C O. , then promoted her to a rank of Sergeant. A few months later, Jennifer picked up her inmate boy friend from the Blythe prison, He just paroled, and traveled to Arizona and robbed a convenience store, using Jennifers gun, then returned to California whereas CHP units stopped them on interstate 10 thus arresting them both. During a search of Jennifer car, her CDC Sgt. uniformed and weapon was discovered. She was fired again. I am at a loss as why she never did ant time, nor why a county sheriff would employ her as a dispatcher. Jennifer was a self centered psycho when I worked with her, always seem to please the Warden. Dr. Todd your time line is on, date and years are correct, but I added personal background regarding Sgt. Jennifer San Marco.

I was working that day on overtime since it was normally my day off. I knew Jennifer San Marco quite well, she would sit with me sometimes at lunch wanting to know how to buy stocks which I knew a lot about. I also knew everyone she killed, they were my co-workers who I had worked with everyday for years. When she started she was a great worker and very friendly, but after about a year that changed and she became a completely different person. Many believed that she had stopped taking her medication but no one really knows. I first noticed it when I said "Hi Jennifer" and she didn't respond but gave me an angry look. I thought maybe I had offended her in some way, I just didn't understand it because she had spoken friendly to me almost everyday for more than a year before that. Anyway, the night it happened, I heard the gunshots while I was scanning Priority Mail and then everyone started to run to the dock where the trucks were, for safety. Dexter Shannon was one week away from retirement. Charlotte Colton was an employee trainer. She actually was not working that night, she had just popped in for a few minutes to leave off some paperwork, even though she could have done it the next morning. A deaf employee that she really liked when she worked there, was at the time clock ready to leave when she spotted him. He later told me she smiled at him and then went on her way, he was spared! Right after she shot Charlotte Colton, she aimed her gun at the head of a lady employee who would have been killed for sure, except for the fact that her gun jammed, giving time for that employee to escape. I had worked at that office since 1989 and loved working there, but after that happened in 2006 it just wasn't the same. I happily took early retirement in January 2013, after 23 years. RIP my beautiful friend 😢 You left us too soon..😭🙏

I've worked as a mail processing clerk for about 12 years now. It really does take A LOT for them to fire people here 🤣

Oh the days when you could just get a regular job and… buy a condo

Working nights is so unhealthy. Also many psych patients I met as a nurse used racial slurs when florridly psychotic and were horrified once they got medicine and stabilized. They were totally different and when well, were often ashamed and apologetic anout their behavior.

"THE MIRANDA SINGS SCHOOL OF COSMETOLOGY" I almost choked on my drink.

Dr Grande, my newborn son remembers your voice from the womb. You should see his reactions when I play your videos 😂

I was a student at UC Santa Barbara and living in Goleta (Isla Vista) when this happened. All I remember that night was riding my bike home from school and my roommate frantically approaching me and locking the door behind me. The police had sent warnings to stay inside but I hadn’t heard anything. Anyway, such a tragic story.

Jennifer was an accident looking for a place to happen.

Imagine the lady who complained about the music didn't know that she had sealed her own fate. sad

Crazy how a person can present normally for years, and suddenly just…switch.

Newman, the U.S. postal mailman in the sitcom Seinfeld explained very well why some postal workers go crazy and ultimately may kill people: ''Because the mail never stops, it just keeps coming and coming and coming. They're never a letup. It's relentless. Every day it piles up more and more and more. And you got to get it out. But the more you get it out, the more it keeps coming in. And then the barcode reader breaks and is clearing house...'' At this point Kramer stops his hysterical rant. Great analysis.

Schizophrenia. Pure and simple.

6 people went to work, believing that at the end of their shift, they'd go home and relax... and instead, their lives were taken, just because they were there. So sad they and the neighbor had to cross path with this lady. Thank you for your analysis on this case, Dr. Grande.

I remember when this happened and the term “going postal”, was heard for ages. Jennifer wasn’t the first, nor was she the last to vent fury at a post office, but she was a wild case.

Wasn’t she involuntarily committed to a psychiatric facility? How did she legally obtain a firearm? This is a big part of the problem.

i worked at a Post Office plant for about a year the redundancy drove me crazy. It was mail mail mail mail by the truckloads for 4 hours everyday then it all had to get sorted....and put right back on the trucks. That didnt include the junk mail that seemed to come out of nowhere.

It sounds like the very familiar story "I feel fine, so I don't need to take my meds anymore."

I was employed by the post office beginning in 2015. In orientation, we were told that if we ever said the words "going postal" at work, we would immediately be fired and escorted out of the building.

im ready to speculate without diagnosing in a situation like this!

Jesus the last two murders were just messed up, you're just doing your job and get shot without warning. You can't run, reflect or pray, it's just all over in a blink of a second. Man I listened to a lot of these but this was by far the most depressing to die just doing your job smh

What disturbing story did she tell her co-worker as a postal worker that got her reported?

If she had lived a hundred years ago she would have been institutionalized and termed insane

We can't have imaginary friends now? Damn, I better go tell my Emotional Support Demon to pack his stuff up 😔

How she passed a background check with no problem? Thanks for the bits of humor haha.

This was interesting for sure and I’m happy when Dr. Grande gives a more “clinical” speculation rather then what the rest of us do ie… “arrogant, vindictive, selfish, self-centered…”

It's so sad that someone was basically in the world alone and had no one to help her. Its hard to be friends with someone with schizo disorders, unless (qnd even if) you knew them before the onset. Thank you for sharing this case Dr. Grande.

Had the San Marco woman received adequate mental health care, none of those murders would have taken place. It's very sad that San Marco had no one in her life to help her when she couldn't help herself. No family. No partner. No real friends.

100% the experiences she had in childhood caused this. Dr. Grande says not a lot is known about that time, but since I've been studying the effects of emotional/physical abuse on children and how it affects their adult lives, it is undeniable that these kinds of mass killings don't just come out of the blue. She absolutely was severely emotionally neglected, this is what causes the mental break which leads to the creation of the "imaginary friends." She may have also been sexual assaulted as a little girl. This offense in particular makes it close to impossible for a person to have close relationships with others as an adult, and often leads to depression/suicide later in life. The only way America is ever going to stop mass shootings is going to be when we acknowledge, as a nation, that the core of all human social, political, and psychological human problems is the wounded inner-child.

When going Postal reaches a whole nother level

I found your analysis of this topic informative. Thank you Dr Grande.

I wonder if she did show signs when she was a younger woman but ppl chalked it up to "being weird" or living in "la la land". like dismissing it to make an excuse for it.

My sister was diagnosed Schizophrenic as an adult but the signs seemed to be there in her teen years as well. She was 17 years older than me so I dont really recall her living at home as she actually married at the age of 19. One part of this story stuck out to me. Her anger towards the neighbor. When my sister was 16 years old our Aunt was making a prom dress for her. Our Aunt who is not very kind or sensitive told my sister that yellow was not her color. She said my sister looked horrible in yellow and looked like a bumblebee. This comment rooted in my sister and grew into hatred of our Aunt. For 3 decades until my sisters death she spoke about our Aunt and this comment. She said many times that she hoped my Aunt would die from a million bee stings. Any misfortune or bad thing that befell any member of our family was blamed on our Aunt.

condolences to the victims families. what a terrible crime spree. she is one frightening person.

Raise your hand if you want to see Dr G wear his Hawaiian shirt with the magenta hibiscus flowers, tomorrow!

One thing notable about these types stories, is that the individual's dilemna in the story seems to span years before they commit the act that makes them infamous, meaning people ought to intervene more to help their minds, such as not outcast, reject or ridicule them.

Hear me out... Maybe we should revisit the option of asylums.

Rest in peace to her victims. Thank us for this video about a very strange incident. Have a great weekend Dr. Grande!

HOW DID SHE GET A FREAKING GUN!!

Dr. Grande, thank you for the upload! 🤌

Wow, I have a neighbor who exhibits some of the same strange behavior (including the weird praying), and used to work at the post office! Yikes....

It's wild that this lady could present such clear symptoms of mental distress, and yet no one was able to help her. We have to do better. This lady was just really sick, and ultimately, that sickness killed her and seven other people.

A friend of mine from Mio Michigan had a sister that worked at Dow Chemical plant and after many years working there she retired and calmly went out of her head in such ways as removing all her clothes and running down a rural rode etc. Nothing violent, but always something unexpected and out of character. Their father also worked there in the early years and died earlier than normal. TOO MANY CHEMICALS.

I'm on my way to a funeral right now. Thanks for the upload, Dr. Grande! Your true fans love your humour and sarcasm. Today (June 1) is National Game Show Day, Say Something Nice Day, Hazelnut Cake Day, Don't Give Up The Ship Day, Pen Pal Day, Dare Day, Dinosaur Day, World Milk Day (gotta have some Earth's Own vanilla almond milk later!), World Olive Day, National Nail Polish Day, Oscar The Grouch Day, World Narcissistic Abuse Awareness Day, International Children's Day, Flip A Coin Day, and National Go Barefoot Day.

Your voice puts me to sleep. I have trouble sleeping…thank you so much!

Listening to this on my mail route 💪

Perhaps men and bears aren’t the only threats people

I think it's more than just a coincidence that people use the term "to go postal" in English. There's something unique to working at the post office in the USA or Canada. In Canada, I don't know how exactly it is now, but for the longest time it was a job in which workers got paid quite a bit of money compared to the easiness of the job. The union is strong because everybody wants their mail. As soon as conditions aren't met, workers can just go on strike. Everybody gets pissed off when their mail isn't delivered, so demand the workers go back. The workers eventually get what they and their union want. I think it gives workers a sense of entitlement. My sister's attitude completely changed once she started a regular job at the post office. She used to be really kind, but after starting work at the post office, she got really macho, vulgar, and entitled. Like this woman, she held grudges. Suddenly everything was our parents' fault, the government's fault, everyone else's fault. I miss my pre-post office sister. We used to be able to talk about our mom, but she made it clear that was not a topic to bring up with her. She'd go into some weird defensive mode. Thankfully she has never shown any violent tendencies and she has become calmer lately, after a new man in her life and quitting the post office. I really do think though that that particular job, at least in Canada and the USA, isn't conducive to good mental health, at least for some people.

Why aren’t Imaginary Friends nice people?

i worked at the post office for 2.5 years back in the 1980's the pressure that the supervisors put on their employees was unreal. there were some pretty mentally ill people that i worked with. there was one man that was bat**** crazy he talked to himself constantly loudly and laughed out loud often. another one was a drunk that did some really wild stuff and also molested his grandsons while taking them on "camping trips."

It’s always sad when people have paranoid ideation because it never ends well. Eventually, they either have these paranoid thoughts about people around them and end up acting on these thoughts to “protect themselves,” or because of their paranoid thoughts, and the actions which accompany them, they annoy/frighten someone to the point where the other person attacks the original paranoid person-a self-fulfilling prophecy. Either way, bad things eventually happen. Assaults and even deaths can occur. Watch out for people with paranoid thoughts.

That’s why you don’t go to work bullying people they might bully you back. God is good. This woman is not a bad person. Absolutely not a bad person. People may have do what she did.

had to go to your page to find this. This website never showed me this video. It also looks like I am the only person who has viewed. Very odd to be sure!

I've been subscribed for a while but lately my fiance started watching you. He thinks you're hilarious. So I started watching again and I'll cracking up on some of the comments. Never realized you were so funny

Any other employer wouldve fired her long before it come to this

Wow, she could hold a grudge. I cant remember past ten minutes let alone be upset that long

Love your opinions and insight 🙏🏻 Don’t take it the wrong way (more of a compliment) but I fall asleep to your videos…your presentation is deep, informative, to the point and calmimg… Keep them coming 🙏🏻 J🇬🇧

'Inconsistent with proper hairstyle management' 😂

I want to know what rap songs she would reportedly rap😂

Thanks, Dr. Grande, this is a case I've never heard of before.

"Amanda Sings' School Of Cosmetology". Nothing is safe from the wrath of Jennifer, nor Doctor Grande.

You tell the situation well. Very cool vibes. I’m definitely binge watching all the videos I’ve missed out on and I’m quite entertained thank You 🙏

Thank you so much for making this video. I really appreciate it. I was very curious about your thoughts on this case.

New Mexico isn't known as "the land of entrapment" for nothing.

I think this is what "going postal" refers to

Very interesting and informative. Thank you for the great video, grande.

Obviously and undoubtedly Jennifer had some serious mental issues.

Yesssssss. Finally covering this case

This is sad 😢 mental illness is so difficult to manage and alot of people don't take their medications

This was 1/2 a mile from my house. What is crazy is another infamous shooter Eliot Roger’s shooting happened 1.5 miles from my house. Both are close to my alma mater, UCSB.

Another case where an involuntary mental health stay was not properly documented, allowing her to pass the NICS background check.

So not only did they let her get a license to publish a periodical called "The Racist Press", but they also let her renew the license as well?? Wow.

Had she survived I wonder if she would have been fired.

You FINALLY said it!!! Making racist remarks IS a mental problem! 🎉

Doc the thumb nail is crazy! GOING POSTAL 😭😭😭😂😂😂😂😂

We're where parents and siblings? Was she abused at home? The healthcare system failed here, there seems to be a total 'not my problem' response from those who knew her

Living large Dr. Grande‼️

Such a well done analysis. Thank you.

😂 Wtf?! This woman was repeatedly walking around naked, singing in public, praying on the side of the road, and the cops were like , " Sweetheart, you gotta go home, and also don't drive naked." With exhibiting these behaviors, this woman should have been institutionalized immediately. The authorities are responsible for this, they have an obligation to protect the public.

When go’n postal turns it to 11

Jesus Christ, how many interactions did she have with the police, well done team

My parents were continually insulted and just as continually vengeful. They targetted me also as an enemy.

The real crime is that someone who dropped out of college and worked for the postal office could afford to purchase a condo in Santa Barbara…..like the inflation and price fixing is OUT OF CONTROL today

Ummm why isn't the imaginary friend being held to account?

I live south of Grants NM. I Remember when that happened.

What a perfect midday upload😊

"Perhaps there was a rule against unincorporated cats getting food, It's not clear." 😂

Riverside to Santa Barbara: good move SB to Grants, NM: interesting change of venue

clearly a classic case of "frankenfurter envy"

Gee it’s sad her mental health was able to decline that bad without someone to step in and help. She was clearly in need of intervention. Without family or close friends she had no one to recognise and help. Medication could have prevented this tragedy

I had a dream where I was blocked by Dr Todd Grande meaning that I couldn't watch his videos anymore. Don't remember what I did wrong. I'm happy to see that it was all a dream! 😅 Edit: I should mention that we met irl. Irl-dream-Dr Grande didn't like me. =/ Must've been something I said.

This one is not as well known as it should be. Saw an episode of Born To Kill on this some years back. Very rare. Oddly reminiscent of Amy Bishop to me.

Always interesting If you came from a Crappy family, why would you want to talk about them. Thank you❤

This was on January 30, 2006. I just don’t want anyone confused that mass shootings are a societal problem now………….not a postal problem.

So postal workers were looking out the windows at the crazy person about to enter the facility and didn’t warn their fellow coworkers wearing ear protection. Hmmm.

I agree. She knew right from wrong. She was deceptive & dangerous, generally people who hop from job to job have issues. Great points again. Thanks Dr G😊💗💗

How many copies of "The Catcher in The Rye" did she have in her home?

I really hope there are no other 'situations like this'!

It is sad she had no friends or family that could have lovingly had her go inpatient while she still worked for the postal service. Lives would’ve been saved. There is a lot of stress working in the post office.
