Mark Barton - The Killer Day Trader

before turning tail and running. What first looked like a financial meltdown spiraled into something far more calculated, a sequence of killings that began in silence at home, and as investigators pulled back the layers the uncovered notes trying to explain the madness, massive financial losses, and even eerie ties that connected the killer to another double homicide. This is the story of Mark Barton, the Killer day Trader.

You'll never be able to purchase those shirts again, but we're given away over on Patreon, and some people can sign up, just like Eric Brett, Howard did Marritt Egan, Jen Herschel, and as well as a Dutch listener who just said there are some wicked true crime stories, which I'm assuming they're meaning like over like where they live, right, So I think we might have to look into doing another Dutch story here soon. Sure, I'm in so but thank

you guys so much for signing up. If you guys are interested, the link is in the description of this podcast. But I think we should get right into the story. Okay, let's do it now. Most weekday mornings don't feel historic in any sense. In fact, they tend to feel rather small and not much different than the one that came before it. You know what, may start with an alarm that goes off, You hit snooze, maybe once or even twice.

Then the shower runs, coffee bruise, and the day begins with no urgency, but it begins instead with more of habit. You might drive the same route that you always drive. You park in roughly the same spot you've parked in for who knows how long. You walk through the doors you walk through hundreds or even thousands of times before that. In fact, if someone asks you to describe the building in detail, you probably easily could with your eyes closed,

just picturing it perfectly. Not because you've paid attention to say all these things, but because the little things have ingrained themselves in your mind over time. There might be a bulletin board that you pass by with a poster on it that's been there way too long. The stairs you climb might have one step at the bottom that one step just doesn't quite align with the rest, But it doesn't matter, because inside that building it's just work.

It's an office with fluorescent lights maybe that hum softly overhead, and computers blink awake, and someone down the hall might laugh at something you can't quite hear. The breakroom even still smells faintly of reheated leftovers from yesterday and stale coffee grounds. The printer whirls awake and phones start to ring. You greet the same people you did yesterday, the same way you always have. You know, morning, how is your night?

Or happy insert day of the week. Here, you sit at your desk, You log in and scroll through some emails. Places like this have their own rhythm. You learn it without realizing your learning it. It gets to a point that even disagreements feel predictable. Someone might get frustrated, someone might vent, someone shuts their door a little harder than usual. But by the end of the day people gather their things and go home. Whatever irritated them feels like it

gets folded neatly into tomorrow. And that's the unspoken rule. No matter how stressful the job gets, no matter heavy or how heavy the workload becomes, no matter how sharp the words exchanged in the conference rooms were there's a line that doesn't get cross. Work is contained. Sure, you might decompress outside of it. You know, you leave and you maybe vent or talk to things about spouse or

even messages with some work friends. But to say the least, most of it stays there at work, and you assume that people around you, no matter how quiet, no matter how intense, are operating within these same boundaries that you are. You don't scan the room for threats, you don't calculate exits, you don't measure the distance between yourself and the door.

Why would you You know these people. You've shared coffee with them, You've complained about management with them, you sat beside them during long afternoons when time seems to slow down. They're a part of the background in your life. Not strangers, not dangerous, just coworkers. There are moments, though, where a line can get crossed, long before anyone realizes it has been. On one ordinary afternoon, in a building that looked like every other building, no one knew they were standing at

the edge of disaster. And then when the door opened in walked Mark Barton now Mark Orin Barton, was born on April second, nineteen fifty five, in Germany. His father, Truman Barton, was serving in the US Air Force at the time, and the family spent part of Mark's early

childhood overseas before eventually settling into Sumter, South Carolina. He was an only child raised in a structured military household, and from an early age he stood out as being rather intelligent, particularly very strong at math and science, but also he was rather emotionally distant. Classmates would later describe him as quiet and socially isolated. He wasn't known to be disruptive or aggressive in school. Instead, he kept to himself.

He excelled academically, especially in subjects like chemistry, but he wasn't exactly social to say the least. He didn't build any strong friendships, and he was often disc decribed as just being withdrawn. By his mid teens, Mark began experimenting with drugs, particularly with hallucinogens, and what may have started as experimentation, it quickly escalated into heavier use. According to later accounts, He was even hospitalized multiple times after overdoses.

Now those close to him suggested that the drugs that he used may have been an escape from feelings or alienation. Whether that was the case or not, though it marked the first documented period where life began to drift off course for him. Now after high school, Mark attended Clemson University before transferring to the University of South Carolina. During this time, he continued down a negative path and was

even charged with burglary and was placed on probation. Around the same period, Mark sought psychiatric treatment following what sources described as a mental breakdown, went therapy and drug treatment, and though there are references that discuss ongoing mental health struggles, there was no formal long term diagnoses that was publicly confirmed.

What is clear, though, is that he had periods of instability alternating with stretches that where he appeared to be focused in high functioning, a sort of flip flop back and forth. Despite all this, though, Mark still completed his degree, and it was nineteen seventy nine when he graduated from the University of South Carolina with a bachelor's degree in chemistry. At this point in his life, there was no public

sign of violence that would later define his name. He was a trained chemist from a military family, very academically capable. He was socially reserved, sure, but there was also that pass that was marked by drug use and some illegal trouble, But there was nothing violent. That's the main takeaway now. After graduating, he found work in chemistry related fields and

eventually relocated to Atlanta, where he met Deborah Spivy. The two even married the same year after he graduated, beginning what appeared to be a very conventional young marriage built around work and family plans. From there, in Mark's career, he worked a series of technical and sales jobs involving chemical products and industrial compounds. Eventually the couple moved to Texarkana, Texas, where Mark helped start a manufacturing company called TLC Manufacturing.

By the late nineteen eighties, he had risen to president of the company and was earning a very strong income of around eighty six thousand dollars a year according to later records. And remember this is even in the eighties.

In nineteen ninety, Mark's relationship with TLC Manufacturing ended and he later described it as an official firing meant to protect the company's image. But what happened next drew some serious attention. See, shortly after his departure, someone broke into the office. They stole proprietary formulas and erased computer files. Now,

as a result, police arrested Mark on burglary related charges. Now, a detective involved at the time thought the break in might actually have been less about theft and more about hiding internal problems, possibly inventory discrepancies or other irregularities.

was no conviction or anything. There was no confirmation that technically it was Mark, but it was Mark, Okay, if you know what I mean, right, let go.

According to his own statements, he changed his appearance during this period, buying new clothes using tanning beds, and he began spending more time away from home. Now his wife, Deborah also grew suspicious of this, and there were incidents of frequent jealousy and arguments where she questioned him about signs that she saw that he might be seeing someone else.

It was around this time that Mark took out a life insurance policy on his wife Deborah, which was valued at roughly six hundred thousand dollars.

found dead inside the trailer. During this trip, both of them had been attacked with what investigators described as a sharp or blunt heavy instrument, something that was like struck the injuries were severe, and the scene didn't look like a break in of any sorts. Cash had had been left behind, alongside other valuables, which made the robbery look very unlikely of being exactly that a robbery.

might clear the way for his new life. Police questioned Mark extensively, and according to later accounts, he appeared very calm during interviews, sometimes almost even challenging against the investigators. He insisted that he'd been in Atlanta during the murders and denied any sort of involvement now, unfortunately without witnesses placing him at the campground authorities were forced to rely

on forensic evidence alone. Now, at one point they managed to search Mark's car and investigators used luminol, a chemical that reacts with blood, of course makes it glow right, and they received positive reactions on parts of the vehicle, including the seat belt and ignition area. Now, Mark claimed he had no explanation at first, and later suggested maybe the blood might have come from a cut on his

finger months earlier. And he also refused to provide a blood sample or DNA sample of any sort to try and do a comparison. He also just declined to take a polygraph test too, So why would he give out anything?

joking around that sort of thing. He simply seemed like a devoted father trying to move on after tragedy. In their eyes, however, the darkness still lingered in him. Friends and neighbors also described some mood swings and controlling behavior leanne. In fact, according to people who knew her, sometimes Eve said that she even appeared uneasy around him. Some said she seemed quieter when he was nearby, as if she was very careful about what she said. Then, there were

also troubling incidents involving the kids. In the mid nineteen nineties, Michelle, who was still very young his daughter, reportedly told a daycare worker that her father had touched her inappropriately. Now the allegation triggered evaluations and legal review, and a psychologist involved in the custody process reportedly stated that Mark was quote certainly capable of homicide.

placed in a trust for his children. But the payout also gave him a lot of financial freedom, and eventually, by the late nineteen nineties, Mark's focus well it shifted away from traditional work and towards a rapidly growing new industry,

internet day trading. When the stock market was booming, Now, the Internet was changing how people invested in the stocks, and a new culture was growing around something that was called day trading, where people buy and sell stocks rapidly, sometimes dozens or even hundreds of times a day, chasing quick profits and turnarounds. Mark fell hard into this world. He opened accounts at brokerage firms including Momentum Securities and

all Tech Investment Group in Atlanta's Buckhead Financial District. Now, these offices, they were built for day traders. There was rows of computer terminals, real time data feeds, and people constantly watching the markets rise and fall. At first, Mark just kind of fit in. He presented himself as an experienced and financially secure and individual, and records showed he claimed a substantial net worth, and coworkers later said he

seemed very confident, even enthusiastic about day trading now. Like many day traders at the time, he focused heavily on volatile internet stocks, the kind that could rise and crash within minutes alone, and if you were on top of it, you could make money. But the markets highs while they were matched by equally brutal lows, and as such, by the summer of nineteen ninety nine, Mark's losses were mounting fast.

According to brokerage officials, he had lost around one hundred and five thousand dollars in roughly seven weeks alone at Momentum, which was only one of the brokerage firms he was at. Some reports even suggested his total losses over the previous year could have reached several hundred thousand dollars as well. The losses triggered something else, pressure from the firms themselves.

So day trading often involves what they call margin accounts, especially they're sorry essentially borrowed money used to increase buying power. It's just kind of like borrowing from a bank situation. You have the money, but it's technically not yours. And when stocks fall sharply brokerage. They issue margin calls, basically demanding traders to posit more money to cover than those losses.

Now Mark actually began struggling to meet those demands. His account at Momentum was reportedly restricted after he failed to cover a margin call. Then, trying to regain access, Mark wrote a fifty thousand dollars check to the firm, but the check bounced, and then Momentum denied him trading privileges, at least temporarily. For someone already under intense financial and

emotional st the restriction was a major blow. People later described Mark as increasingly anxious and angry during this period, and at home arguments with Leanne reportedly became more frequent too, especially over money. Mark still tried to protect the normalcy in his life though how people saw him. He kept buying gifts for his children, spending time with them, acting like a regular suburban father, But those financial losses were just piling up, and tensions at home were growing right

along with it. Then, in the early hours of Tuesday, July twenty seventh, while Leanne slept in her Stockbridge apartment, he attacked her with a hammer. The assault was sudden and brutal, as she was struck repeatedly in the face and head and died right there in bed where she laid. Afterward, Mark dragged her out of bed and hid her body in the master bedroom closet, covering her with a blanket and placing boxes and clothes around it to conceal. And then he cleaned up.

turned on his kids. He later claimed that he believed he was sparing them from future suffering, but that is just his twisted rationalization of what's in his mind, basically of a monster's mind. In reality, he put them through something unimaginable. He attacked both the children with the very same hammer that he used on his well wife while they were asleep too. Mark then placed their bodies face down in a full bathtub to make sure that they worked out.

cared for. Another handwritten note was in place with Leanne to where she laid in the closet still, and he called her his precious love. In the living room, Mark left a longer typed out letter printed from a computer, and by the morning of July twenty ninth, things began quietly inside that Stockbridge apartment. The bodies of Mark's wife and children remained there, right where he had placed them, and Mark began moving through that morning with a sense

of purpose. Mark left his apartment and then made several deliberate stops through ti him, one of which was his attorney's office, where he reportedly made some changes to his will. Then he drove towards Atlanta's financial district, carrying two handguns with them a nine millimeter any forty five caliber pistol, along with, of course, plenty of ammunition. People who encountered him that morning described nothing unusual about his appearance. He

wore casual clothes and behaved normally. When he arrived at Momentum Securities around early afternoon, he walked in just like any other day trader did. That Thursday, the market itself was down. It was another bad day for traders, but employees they recognized him. They chatted casually with him, and he did so back with other staff members and other traders and smiling, making small talk, all while waiting for management. Some believed he was just there to discuss money or

try and resolve his issues with his account. He appeared calm, even friendly, so no one thought anything of it. None of them knew that he had just murdered his family ash and for roughly twenty minutes, Mark waited. The trading floor buzzed with the usual energy of people watching the markets, chasing gains and reacting to losses. Shortly after three pm on July twenty ninth, nineteen ninety nine, the atmosphere inside Momentum Securities was typical. Terminals glowed with live market data.

Traders watched those screens, but Mark had been inside for about twenty minutes, and he was apparently waiting, but there was no raised voices or visible rage with him. But all of a sudden, without any clear sign, he just reached for his weapons. Witnesses later said Mark pulled out both guns, one in each hand, and he reportedly smiled. According to multiple accounts he made a chilling remark before firing, and now variations of the quote have been reported, but

the message was the same. He essentially said the trading day was bad and it was about to get worse, and then he opened fire on the room. The first shots were close ranged and victims were struck almost immediately. The confined office space amplified that sounds of the gun turning the trading room floor into chaos within seconds. People dove under desks, others ran towards exits, and some were hit while trying to escape. But Mark he didn't flinch.

He simply moved through the space, pulling the trigger repeatedly on both weapons. Four people were ultimately killed at momentum. Others were wounded, some critically, and survivors later described blood being on desks, on walls, and all over computer screens, and the scene unfolded quickly but felt endless to those inside. Panics spread beyond that immediate office, as employees in nearby

suites heard the shots too, emergencies. They had calls flooding in through nine on one dispatchers, and within minutes police were racing towards the Pimont Center, where the shooting was unfolding, but Mark didn't stay there. Before officers could fully lock down the building he had left. Some reports suggested he

exited calmly, blending in with the fleeing employees. Others recall seeing a man moving quickly away from the scene, but either way, just across the street, just steps away, stood another brokerage, where Mark also traded all Tech investment group. Oh my goodness, and he was headed straight for it.

he produced those same two weapons. Managers and a secretary were hit with bullets at close range almost immediately, and survivors later described confusion, with people struggling to understand what was happening, and before anyone could react, Mark moved from that office with the managers into the main trading floor room, and he began firing across that open room, targeting people as they dove or tried to hide and run. Some

were struck while attempting to reach exits. Other drop behind desks or crawls crawling across the floor, and they were hit and trying to find any sort of cover. It was just chaos, and he was seeing anyone and firing indiscriminately. Witnesses recalled him moving steadily through that space, continuing to shoot as he went. Several victims died where they fell,

and others were critically wounded but thankfully survived. Now. During the attack, Mark reportedly made another chilling statement, something to the fact of hoping he was not ruining anyone's trading day.

Officers flooded the Piedmont Center complex, parking cars and control cars all over to try and block entrances. Swat teams moved floor by floor, clearing offices, escorting terrified employees out of the buildings. Helicopters circled overhead ambulances lined the street as paramedics rushed the wounded to nearby hospitals and inside the buildings, automatic locking systems had actually even been engaged,

which trapped some employees in the office. Many witnesses called local radio stations and television stations, describing gunfire, screams, and all the confusion surrounding it. Blood covered the desks and the floors, and police made their way through just trying to find these survivors and then escorting them out. They even had to make sure they had their hands raised,

unsure if the shooter was still in there. So they're saying, hands up, to make sure that you can appear like you're not unarmed, you're not a police officer, just in the odd chance that he's waiting.

Authorities quickly expanded the search perimeter beyond Buckhead into Cobb County and surrounding suburbs were alerted to officers, canvas, wooded areas, and parking structures, and because Mark reportedly held a pilot's license, airports were notified in case he attempted to flee by air. As well. As the afternoon stretched into evening, fear spread across the metro area. News outlets interpreted the programming with

live coverage, and the city's mayor, even Bill Campbell. He described the scene inside the office as an awful lot of blood everywhere, and he called it a long, unspeakable day.

investigation was quietly unfolding about twenty miles away in Stockbridge, Georgia. Now, at first, this other investigation had nothing to do with the Masacre. Down Town. Apartment management at Bristol Green Complex had simply reported that the rent was late and something

felt off with one of their units. At around three point twenty three pm, less than half an hour after the first shots were fired in Atlanta, a Henry County Police officer entered the apartment with assistants from the property manager. When the officer entered, they found something that was very

disturbing that changed the direction of the entire case. They found the body of two children that were discovered first, eleven year old Matthew Barton and his younger sister, Michelle, who were lying in their beds, carefully positioned wrapped in blankets with their faces exposed, each with a handwritten note. As officers continued to search the apartment, they soon found a third body, Mark Barton's wife, Leanne. She was located in the master bedroom closet, hidden beneath a blanket, also

with a handwritten note. In the living room, officers found the last letter, addressed to whom it may concern. The note was timestamped early that morning, July twenty ninth, at six thirty eight am. In it, Mark described killing his wife first and blamed her for his downfall. Then he said he killed his children next the next night, and

he did so to spare them the pain. He claimed he'd use a hammer while they slept, then placed some face down the bathtub to ensure they were dead, and he also wrote that he intended to kill quote as many of the people that greedily sought my destruction end quote. The note also referenced the unsolved nineteen ninety three murder

of his first wife and her mother. Mark denied responsibility for those deaths, insisting that there was quote no reason to lie now end quote, even though he acknowledged the similarities in the killings.

driven by financial stress. But it was now clearly part of a much larger and more personal killing spree. Mark had he killed his wife days earlier. He then murdered his children, and then he just went out and continued to mow down people that he believed did him wrong. It wasn't financial, it was anger, it was personal. It was a vendetta. Sure that might be financing there in

that reason, but it was personally motivated. News of the discovery spread quickly through law enforcement channels, and by late afternoon, while Atlanta was already in a massive man hunt, witnesses began reporting sightings, and hours passed still with no confirmation of where Mark was. Then, around seven forty pm, security personnel at a shopping mall in Kennesas spotted a unattended van matching the description that was put out to the public.

Almost simultaneously, a woman in a parking lot reported a frightened, frightening encounter with a man carrying a black bag, who warned her not to scream or run. Another witness recognized Mark from television coverage and called nine one one two, providing police with the van's location and direction of travel. Cobb County officers quickly picked up the trail, and one officer, hughle Clements, spotted the van on Interstate seventy five and

began following at distance, waiting for backup. Then, at approximately seven to fifty pm, Mark exited the interstate onto Georgia Highway ninety two and pulled into a gas station in Ackworth. Patrol cars moved in on him almost immediately for there, boxing the van in from multiple angles. Officers exited the vehicles with guns drawn pointed at the van, shouted commands from Mark to step out, but before they could reach him and do anything, Mark raised a handgun inside the

van and a muffled shot rang out. Then his body slumped forward against the steering wheel. It was roughly seven point fifty five pm when officers cautiously approached the vehicle. I'm sure if he was still alive or if there was additional threats inside, but moments later the danger was confirmed to be over. Mark Barton was dead from a self inflicted gunshot wound to the head.

Atlanta brokerage firms. More than a dozen were also wounded, many with life altering injuries, and it was immediately described as one of the deadliest mass killings in Georgia's history. At momentum Securities, four people were killed, including traders and staff who'd been working in normal afternoon when Mark arrived at Altech. Five more lost their lives after Mark crossed

the street and opened fire inside that building. Hospitals across Atlanta had quickly filled with victims, and emergency crews had prepared for multiple casualties, but many said that they had never seen anything like this volume of wounded arriving from an office or a corporate setting all at once, and as news spread that Mark's wife and child had been found murdered in Stockbridge, the emotional impact only deepened from there.

City officials tried to steady the shocked public. Office workers across Buckhead were evacuated or locked down for hours, unsure whether the shooter was even still nearby it all, and families of the dead began speaking publicly In the days

that followed. Some struggled to understand why their loved ones had been targeted at all, and investigators later even said that there was no clear evidence that Mark selected specific victims inside the office, although some reports suggested a few had previously lent him money or were connected to his trading losses. Whether he intended to target individuals or simply anyone at all who was in front of them, while it remains uncertain.

people understood that the Atlanta shootings. Suddenly, the story was no longer about a financial collapse and a workplace shooting. It was also about a mystery that had lingered unresolved for six years prior to that. In September of nineteen ninety three, Mark's first wife, Deborah Spivy Barton, and her mother, Eloise Bivvy were found brutally killed inside a camping ground

inside a trailer near Lake Weese in northeastern Alabama. They traveled there for a holiday weekend and then they were just killed violently with what appeared to be a heavy or sharp object. And to top it off, the crime scene showed no signs of force entree, leading police to believe the victims likely knew whoever entered the trailer, and

from the beginning, Mark drew attention from investigators. Just weeks before, of course, there was the large life insurance policy reportedly six hundred thousand dollars, money that would ultimately lead to his day trade, which would ultimately lead to more killings.

And at that same time his marriage was deteriorating. He was involved in an affair with LeeAnne, the woman he would later marry and later kill, but Mark denied any sort of involvement in that case, even in his suicide note he left behind, he denied it, even though there are so many connections between each one. Investigators in Alabama reviewed the old files again after Mark's death, but without a living suspect to question, without evidence, there was nothing

they could do. The case remained open but unresolved, leaving families with no legal closure, and officially speaking, those two deaths are not on Mark's record.

a much larger and darker pattern. Now in Atlanta, the massacre left a very lasting mark. The victim's names had become part of the city's history, remember not as statistics, but as co workers, friends, and family members who lived well and worked during an ordinary day that turn not so ordinary, and the legacy of the case ultimately lies

in its complexity. It was a family tragedy, a workplace massacre, and a financial collapse, all wrapped up in a story shadow by unreserve, suspicion from years earlier, and a hidden darkness deep inside someone. There was no single explanation that explained everything, no simple motive that could tie everything neatly up. What remained in this timeline that reads almost unreal in hindsight, is a man who appeared to be normal, a rapid descent behind everyday life and a city forced to piece

together the truth after the fact. The investigation ended when Mark turned that gun on himself and pulled the trigger at that gas station. But the questions it all raised, well, it'll never go away, and that's a story of Mark Barton, the killer day trader.

that's what it was. He did good, well, thank you, but it was he came out of nowhere. He did such violence, and it made such little sense.
