Angels of Death: 8 Medical Murderers

Original image

Serial murderers can come from any background and work in any profession. However, medical careers make it easy for someone who is inclined to murder to carry it out, and to cover it up. And to do it again and again.

The Doctor of Poison

Michael Swango is believed to have poisoned dozens of patients under his care. Despite a troubled medical school record and a 1985 conviction for poisoning, he was able to find employment in several states and one other country until his 1997 arrest for murder. Nurses had noticed Dr. Swango's patients died at an unusually high rate as early as 1983, but their suspicions were brushed off, and Swango changed jobs and locations often. He also forged documents and falsified his resume to gain employment, and hospitals didn't check his background thoroughly. His reputation caught up with him in 1994. Swango was under FBI surveillance, but fled the country before an arrest warrant could be served. Dr. Swango had found employment in Zimbabwe, where no one had heard of him. There, the pattern of unexplained deaths continued and Swango was arrested. He absconded before his trial, and was on his way to new employment in Saudi Arabia when US officials arrested him for fraud during a layover in Chicago. Swango pleaded guilty, and was incarcerated when murder charges were filed in 2000. He pleaded guilty to three murders in exchange for avoiding a death sentence or extradition to Zimbabwe. He was sentenced to life in prison without parole.

The Center of Attention


Beverley Allitt had a history of drawing attention to herself by faking injuries or illness while growing up in Britain. In 1991, she was working in Children's Ward 4 at Grantham and Kesteven Hospital in Lincolnshire. An unusual number of emergencies began to happen during a 15-day period, in which a child would suffer a heart attack or other crisis and then either died or was revived at the last minute. A couple of the children were transferred to other hospitals, where they recovered. An autopsy of one child revealed a high level of potassium, leading to more autopsies that showed high levels of insulin or other unnecessary drugs. 25 suspicious episodes involving 13 children were identified. They only had one thing in common: Beverly Allitt was on duty during every one of them. She was arrested several months after the investigation began and charged with four counts of murder and 11 counts of attempted murder. Allitt was diagnosed with Munchausen's syndrome and Munchausen's by Proxy syndrome. In the former, a person fakes or inflicts injury on illness on himself to get attention; in the latter, the injury is inflicted on someone else for the same reason. Allitt was convicted in 1993 and was sentenced to 13 life sentences. She is incarcerated at a high-security mental hospital.

Helpling Them Die

00MFMalevre.jpgNurse Christine Malèvre worked at a lung hospital in Mantes-la-Jolie, France. She was charged with the deaths of seven patients in 1997 and 1998. Malèvre had written a book entitled My Confessions, in which she described how she "helped" patients who were terminally ill and in pain. She confessed to police that she had terminated as many as 30 patients out of compassion, but she later recanted and said she had only caused two deaths and two others were accidents. Malèvre was convicted of six murders in 2003 and received a ten year sentence. Her case sparked a nationwide discussion on euthanasia in France, where assisted suicide is illegal.

The Night Shift Gang


Waltraud Wagner was a nurse's aide at Lainz General Hospital in Vienna, Austria. She worked the night shift on a geriatric ward where people died from natural causes at a higher rate than the rest of the hospital. That rate went up between 1983 and 1989 when Wagner and three colleagues killed between 42 and 300 patients. The first death was a woman who asked Wagner to end her suffering. Wagner obliged by injecting her with morphine and found she enjoyed killing. She recruited her coworkers, Stephanija Mayer, Maria Gruber, and Irene Leidolf to carry out more murders. The four killed not only patients who were dying, but those who were annoying or hard to care for as well. The death rate was noticed, but the murderers weren't caught until 1989 when a doctor overheard the group discussing a recent killing. After arrest, the four admitted some murders and implicated each other for the rest. Wagner, who originally boasted to police that she was responsible for 39 murders, recanted and would admit to only ten by the time their trial began in 1991. Waltraud Wagner was convicted of 15 murders and 17 attempted murders, and drew a life sentence. Leidolf also received a life sentence, and Mayer and Gruber each received 15 year sentences. All have been now released from prison.

The Fasting Cure

00hazzard.pngLinda Hazzard claimed to have a medical degree as a "fasting specialist". She treated patients in Olalla, Washington by starving them, sometimes to death. Patients were given only weak broth as nourishment and powerful enemas that left them weak and delirious. Then Dr. Hazzard would have them make out their wills, with her clinic as beneficiary. At least a dozen patients died under her care, until an investigation by the family of Claire Williamson resulted in the doctor's arrest in 1911. Williamson weighed less than 50 pounds when she died. Hazzard was found guilty of manslaughter, served two years, then moved to New Zealand where she again practiced as a "fasting specialist." She returned to Washington State in 1920 and built the sanatorium she had dreamed of -and tried to finance with her dead patient's money. However, since she was barred from practicing medicine, the building was named "a school of health". Hazzard died in 1938 when she decided to try her own fasting cure.

Money as a Motive


Anna Marie Hahn was the first woman to die in Ohio's electric chair, and only the second woman executed by the state. She immigrated from Germany in 1929. After divorcing her second husband, Hahn began working as a private live-in nurse for elderly German men in Cincinnati. Her patients tended to die and leave their fortunes to Hahn, which helped pay for her gambling habit. The string of unusual deaths ended in 1937, when police found a suspicious amount of arsenic in George Obendoerfer's body. An investigation revealed 11 unusual deaths among Hahn's patients, and a survivor who caught her trying to poison him. Hahn was convicted of one murder, that of Jacob Wagner in 1937. Her own 12-year-old son testified against her at the trial! She was executed in 1938.

The Fast Worker

00MForvillemajors.jpgFrom 1993 to 1995, 130 patients died while nurse Orville Lynn Majors was on duty in the ICU at Vermillion County Hospital in Clinton, Indiana. An investigation into the unusual death rate turned up this vital statistic:

From March 1, 1993 to March 31, 1995, (the dates of Majors employment), a death occurred every 23.1 hours that Majors was working. When he was not working (during the same period of time) one death occurred every 551.6 hours.

As soon as Majors was suspended and relieved of his nursing license in 1995, the ICU death rate fell to pre-1993 levels. 79 witnesses testified at his trial, in which the judge ruled that the death rate statistics were not admissible because Majors was only on trial for six murders. However, he was convicted on other evidence, including potassium chloride and syringes found at his home. Many of the victims are believed to have been injected with potassium chloride, a poison notoriously hard to identify. Majors was convicted in 1999 and received a sentence of 360 years in prison.

The Hero of Children

00MFgenenejones.jpgGenene Jones was a pediatric nurse in Texas who wanted to be the hero, to save a child's life. In order to do this, Jones first had to endanger the child's life, but she wasn't always successful in saving that life. While working at Bexar County Medical Center Hospital, other nurses noticed that children with normal illnesses tended to have seizures or cardiac arrest when Genene Jones was on duty. Some autopsies showed the children had been given heparin or Dilantin which was not prescribed. Hospital officials resisted an investigation, but transferred Jones out of pediatrics. She reacted by resigning. She began working at a pediatric clinic in Kerrville, Texas. The same pattern of seizures and unexplained crises occurred in children under Jones' care. An investigation found 47 suspicious deaths while Jones was at Bexar County Medical Center. She was indicted on one charge of murder and charges of injuring other children. Another indictment was later filed on an additional injury charge. Two trials on the various charges were held in 1984, both winning convictions against Jones, and she was sentenced to a total of 159 years. She has been denied parole once, and will be eligible again in 2009.

If your favorite medical murderer isn't featured in this list, that's probably because he or she will be featured in part two coming next week.

Update: Parts two and three of this series are now available.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

What Happened to Jamie and Aurelia From Love Actually?

Fans of the romantic-comedy Love Actually recently got a bonus reunion in the form of Red Nose Day Actually, a short charity special that gave audiences a peek at where their favorite characters ended up almost 15 years later.

One of the most improbable pairings from the original film was between Jamie (Colin Firth) and Aurelia (Lúcia Moniz), who fell in love despite almost no shared vocabulary. Jamie is English, and Aurelia is Portuguese, and they know just enough of each other’s native tongues for Jamie to propose and Aurelia to accept.

A decade and a half on, they have both improved their knowledge of each other’s languages—if not perfectly, in Jamie’s case. But apparently, their love is much stronger than his grasp on Portuguese grammar, because they’ve got three bilingual kids and another on the way. (And still enjoy having important romantic moments in the car.)

In 2015, Love Actually script editor Emma Freud revealed via Twitter what happened between Karen and Harry (Emma Thompson and Alan Rickman, who passed away last year). Most of the other couples get happy endings in the short—even if Hugh Grant's character hasn't gotten any better at dancing.
