Cases Of Employees That Went Psycho And Murdered (Or Almost Murdered) Their Bosses

If you’re like most of us who have had several jobs over the course of your career, you’ve had a few good bosses—the rest have been, more or less, awful. That little bit of power that comes with having an employee can and often does turn people into monsters.

Personally, I’m still in touch with a few of the people for whom I worked. Their numbers are in my phone, and I reach out to them from time to time to wish them well on a major holiday. I’ll even have lunch with one of them from time to time. The rest of those bosses? If they were to randomly drop dead, I doubt I’d shed a tear. There’s just an aspect to the employer-employee relationship that many find uncomfortable.

That said, there is a huge difference between not really caring if a person with whom you once spent a significant amount of time perishes and actively going out of your way to make sure he or she can never irritate you again. Unfortunately, people do kill their bosses, especially after that boss severs the employer-employee relationship.
Here are fifteen examples of people who did just about the most awful thing possible to the person once referred to by them as “boss”.

1. Irelio Reyes Osorio

Unless you taste beer, wine, or spirits for a living—which sounds like a great job—drinking during the workday is generally unadvisable. Sure, many of us feel like doing so on a regular basis, but it rarely works out well for the employee or the company for which he or she works. Most workplaces have pretty firm rules when it comes to getting intoxicated while trying to do an honest day’s work.

Irelio Reyes Osorio apparently enjoyed drinking on the job, so he did, which resulted in his termination. In March of 2017, the Miami Lakes resident decided he would “get even” with his supervisor by trying to stab him and run him over with a car. The boss didn’t actually die, but Osorio was arrested and charged with attempted first-degree murder. The two had met up, and Osorio was looking to get paid for a couple of days work, and that’s when the unfortunate incident occurred.

Osorio also sent his supervisor numerous threatening text messages prior to trying to murder him.

2. Eric Allen Kirkpatrick

Possibly the saddest part of this story is that Vancouver resident Eric Allen Kirkpatrick decided to take the life of his former boss Benjamin Banky at an office Christmas party. His doing so probably really ruined the holidays for everyone attending TallGrass’ holiday festivities.

Banky had fired Kirkpatrick the day before the holiday party. Kirkpatrick used a shot gun to end Banky’s life. At one point, Banky tried to protect himself with a chair, but the shot went through it. Two more shots were fired.

3. Mario Betancourt

Back in the early 2000s, Florida resident Mario Betancourt’s actions earned him attention from the American television show America’s Most Wanted. In 2000, Betancourt, who at one point upholstered exercise equipment for a living, shot and killed his former boss and a co-worker; Betancourt had been accused of stealing. He shot his coworker five times and his boss twice.

Betancourt ended up fleeing the state and eventually the country, eventually settling in Cancun. Because he used so many aliases, he was difficult to track and locate, but he was allegedly in both Maine and Pennsylvania before escaping the United States.

In the spring of 2001, Betancourt was found in Cancun, Mexico thanks to the efforts of the Federal Bureau of Investigations. Four years after he committed his crimes, he was returned to Florida to face charges of first-degree murder.

4. Rodney Jackson

In June of 2015, Rodney Jackson of Texas was summoned into a conference room by his boss and asked to sign termination papers. Jackson refused to do so, and he stormed out of the conference room. The boss, Jason Yanko, and another employee of the company for which Jackson worked saw Jackson leave the building and go to his car.

The 49-year-old Jackson returned to the building with a pistol in his pocket and then, after a brief confrontation, started shooting. Yanko was shot several times—at least once in the face—and died shortly thereafter. The termination papers Jackson refused to sign were still in Yanko’s hands.

Jackson then fled the scene of the crime in a stolen truck, but eventually turned himself in.
Yanko had just moved to the area and started working for the Houston branch of the company, Val-Fit, for which Jackson was working at the time of the homicide. Yanko was married and had three children. He was 40 years of age at the time of his death.

Naturally, Jackson was charged with murder.

5. Christian Rene Haley

Technically, Christian Rene Haley didn’t kill his boss; instead, in December of 2013, the 20-year-old man murdered the wife and daughter of his boss.

Angry that he had gotten fired for attendance problems earlier in the year, Haley showed up at the Indianapolis home of Todd Erb, his former boss and bashed in the skills of his ex-employer’s female relatives using a cement block. Erb returned home to find his dead wife and daughter in pools of their own blood.

Haley stole several objects from his victims, including an iPhone and pearl earrings.
In 2015, Haley was found guilty of killing the women; he is serving life in prison, and there is no possibility of parole.

While what he did is truly terrible, Haley does have a history of mental problems, and those problems may have been a factor in the killings. The court, however, did not believe Haley was unable to understand that he was committing a crime when he ended the lives of the Erb women.

6. Byran Uyesugi

In November of 1999, Byran Uyesugi brought a loaded semiautomatic pistol to the Xerox office building in Honolulu, Hawaii at which he worked. He killed his supervisor as well as six of his co-workers. He used a special kind of bullet designed to inflict higher tissue damage.

Why did he do it? Well, his employment at Xerox was problematic from the start, really; he had accused his coworkers of harassing him and sabotaging him. Eventually, he started making death threats. The guy definitely had anger management issues, and he had to undergo psychiatric evaluation.

The proverbial “straw that broke the camel’s back” seemed to be when he was required to be trained on a new Xerox machine model; he snapped as a result. The day after being told he would require the training, he went on his killing spree. There was a team meeting going on at the office at the time.
In 2000, Uyesugi was found guilty of first-degree murder. The sentence was life in prison, without the possibility of parole.

7. Howard Huh

Forty-year-old Alex Huh was shot and killed in Hollywood in June of 2008. The killer? Another man with the last name of Huh, who was not related to the victim. The killer, 67-year-old Howard Huh, had worked for Alex Huh at the spa he owned. The shooting occurred during an argument between the two men; the argument was related to a dispute over the ownership of the business, over which there was a protracted legal battle.

Howard Huh, to his credit, turned himself into the Los Angeles Police after the shooting occurred, and he was sentenced to 40 years in prison when found guilty of second-degree murder.8. Andrew John Engeldinger

It was Thursday afternoon in late September of 2012 when Andrew John Engeldinger walked into Accent Signage Systems’ building in Minneapolis, Minnesota with a 9mm pistol. You know where this going.

Engeldinger was an employee of the firm, a sign-making business; when told on that fateful Thursday that he was being terminated, he used his pistol to kill the firm’s upper management, including the company founder. He also took out a UPS driver.

Engeldinger is not in prison for his crimes, however. He shot and killed himself in the basement of the warehouse of his former business.

Reportedly, Engeldinger was a “loner” who had poor relationships with his coworkers. Family members speculated that he had an untreated mental illness, which would explain why he did what he did.

9. Caswayne Williams

In 2017, a 23-year-old former Walmart Neighborhood Market employee stabbed his 25-year-old boss; Caswayne Williams had recently been fired from the Orlando, Florida store, allegedly as a result of making derogatory remarks about race and sexual orientation.

The victim, Davon Brown, was reportedly found saying the given name of his killer. He later died in a hospital.

The case against Williams is still ongoing, but he was apparently caught on surveillance video. Another employee of the store allegedly witnessed the stabbing.

Williams, who was born in Jamaica, had been homeless in New Jersey before moving to Florida and getting a job at the Walmart Neighborhood Market.

Williams has been charged with first-degree murder.

10. Chanthinh Sangthavong

Sangthavong was working at a Pepsi bottling facility in California in 2004; he then killed his former supervisor after losing his job. His victim was a 32-year-old man named Jerry Sarnowski. He allegedly followed his ex-boss home from work; in the middle of the night, Sangthavong shot Sarnowski on his doorstep.

All these people killing their bosses really makes you wonder why people go into management, doesn’t it?

Sangthavong was found hiding in an apartment, and he was peacefully apprehended.

11. Marion Guy Williams

In early May of 2016, a former employee at Knight Transportation—Mario Guy Williams—walked into the place where he was once employed and shot the man who was once his supervisor. Armed with a handgun and a shotgun, Williams killed his ex-boss, who left behind a wife and 2-year-old child. Williams apparently thought the boss in question, Mike Dawid, had “ruined his life”.

Williams also killed a co-worker in addition to his boss; he would then take his own life in the very place where he had taken the lives of others.

12. David M. Stead

In early July of 2016, a New Jersey man—surprise—killed his former employer. David M. Stead broke into the home of his ex-boss, shot the man dead, and then robbed the home.

Senseless murders are always awful, but what makes this one particularly tragic is that the victim—a 49-year-old man named Thomas Wright II—was found by his own father. The family was concerned because Wright had not shown up for work at the place where Stead once worked.

Shortly thereafter, Stead was arrested by New Jersey State Troopers.

13. Rene Alfaro

Rene Alfaro is in trouble with the law for—and this should come as no surprise at this point—killing a former boss. In April of 2016, Las Vegas was subject to Alfaro’s hatred for his former employer; what makes this crime noteworthy is that the boss—Kevin Hockar—wasn’t shot just once, but up to 10 times with a rifle.

Alfaro had been fired from the paint and stucco business run by Hockar about two months before the fatal shooting.

14. Jeffrey Johnson

A lot happens in the city of New York, and the Empire State Building is one of the most famous structures in the world. In August of 2012, that building was the site of a horrible murder. 58-year-old Jeffery Johnson, who was a clothing designer who had been laid off, fired a round from a semiautomatic weapon into the head of a former co-worker. He then fired four more rounds.

According to police, Johnson blamed his victim—who was a vice-president at the company for which Johnson worked—for his financial problems and the fact he was about to get evicted from his apartment.

Johnson was killed by police shortly after the murder; several innocent people were wounded by the officers. Fortunately, no one other than Johnson perished due to the incident.

15. Darryl Dinkins

New York City transit worker Darryl Dinkins believed his managers to be racist—or at least he accused them of being racist.

The long and short of it is that the bodies of his two supervisors were found in a trailer in late February 2004; they had been shot and killed. There was definitely a level of animosity between Dinkins—who cleaned rained cars—and the victims. Disciplinary reports had been written by the victims against Dinkins.

Allegedly, Dinkins was in a drunken rage when he killed his managers. Did he kill them? Well, it is possible no one will ever know for sure; regardless, in October of 2006, Dinkins was acquitted of all charges related to the deaths of the men he once called his bosses. He hugged his mother after leaving the courtroom where he could have been convicted of murder.
