Angels of Death: 7 More Medical Murderers

Original image

In part one of Angels of Death, you saw the stories of eight medical professionals who killed their patients. That's just scratching the surface of the many cases of medical murders. Here are seven more.

Nightmare Nurse

Jane Toppan admitted to first eleven murders, then later to 31. Despite recklessness with drugs, unusually high patient deaths, and charges of theft, she managed to find employment over and over again in Massachusetts between the years of 1885 and 1901. In 1901, Toppan moved in with the Davis family after the death of the elderly mother she had cared for. Within a short time, the father and two daughters were dead. She also killed her foster sister before an investigation, which found the victims to be poisoned, led to her arrest. Toppan was found not guilty by reason of insanity, and was held in a mental institution for the rest of her life. Toppan was said to have been proud of the killings.

The Angel of Death

Two of the people profiled here are very different from the rest in that they did not hide their actions at the time. One was Joseph Mengele, who had free rein under the SS to conduct experiments on inmates at Auschwitz. The doctor was also largely responsible for selecting prisoners for the gas chambers. Mengele had a special interest in twins. Thousands of twins were subjected to horrific surgical procedures and injections. Only a few survived World War II. Mengele also "experimented" with electric shock, castration, radiation, and removal of limbs and organs without anesthetic on manner of prisoners. Mengele escaped to Argentina after the war under a false identity. The records he kept on his experiments were destroyed by a colleague. Mengele died in 1979 in Brazil. A grave was exhumed in 1985 and DNA tests in 1992 confirmed that it was Mengele's.

The Job-hopping Nurse

Charles Cullen worked as a nurse at ten different hospitals in New Jersey and Pennsylvania and admitted killing 45 patients between 1988 and 2003. He administered overdoses of drugs (usually digoxin) by injection or through intravenous lines. He was fired from job after job for erratic behavior, incompetence, or breaking rules, but Cullen continued to find work because of a nationwide nurse shortage. Suspicious deaths at Somerset Medical Center in New Jersey finally led authorities to look into Cullen's background. He was arrested for one murder and one attempted murder in 2003. He later confessed and pled guilty to the charges. In later investigations, Cullen pled guilty to 13 murders at Somerset and three more at other hospitals in New Jersey. He also pled guilty to killing six patients in Pennsylvania. Cullen is serving 18 life sentences and will be eligible for parole in 395 years. The nurse explained that he killed because he couldn't stand to see his patients suffer, although he seemed unaware that in many cases, he caused their suffering. As a result of the Cullen case, most states adopted laws that provided legal immunity to employers who give poor performance ratings or referrals to medical professionals.

Dr. Death

440_kevorkian.jpg

There are many who would not consider Jack Kevorkian a murderer, but he was convicted and served eight years in prison for second-degree homicide. Kevorkian was an activist who published and spoke on the ethics of euthanasia. He pushed the idea that terminally ill patients and even those with a limited quality of life, should have the right to commit suicide, even those who are not physically able to do so. Kevorkian developed at least two devices that allowed patients to deliver their own death with a simple push of a button. The doctor, whose license was revoked in 1991, says he assisted in over 100 suicides. He was arrested numerous times, but wasn't convicted until 1998 because the patient had made the ultimate move in each death. However, Thomas Youk was completely paralyzed due to ALS (Lou Gehrig's Disease), so Kevorkian, with the patient's permission, administered a lethal injection. The event was videotaped and shown on the TV show 60 Minutes in 1998, which led to murder charges for Kevorkian. He was denied parole until 2006, when he finally promised not to involve himself in any more suicides. At the time, Kevorkian was expected to die of Hepatitis C within a year. However, he was healthy enough to run for a Michigan congressional seat in 2008. He did not win the election.

The Veteran Murderer

220_gilbert.jpgWhen nurse Kristen Gilbert moved to the evening shift at the VA Hospital in Northampton, massachusetts, the death rate tripled. Other nurses noticed patients dying of cardiac arrest when there was no history of heart trouble. They also noticed epinephrine, a drug that can cause heart attacks, sometimes went missing. And they noticed Gilbert's affair with security guard James Perrault, who was always called when an emergency arose on the ward. It was thought that the nurse would induce a heart attack solely for the opportunity to summon her lover to the scene. Authorities investigated in 1996, Gilbert was suspended, and the death rate immediately dropped to normal levels. Perrault broke off the affair, and Gilbert tried to kill herself. She landed in a psychiatric ward, where she admitted to  Perrault that she killed patients. Her former lover then aided the investigation against her. Gilbert called in a bomb threat to the hospital, asking to speak to Perrault. She was arrested for the act, and later charged with four counts of murder and two counts of attempted murder. She was convicted in 2001 and sentenced to life in prison.

The Compassionate Killer

440_letter.jpg

Stephan Letter was convicted of murdering 16 patients and causing the death of 13 more, although the line between the two charges seems blurry. Letter was a nurse at a clinic for the elderly in Sonthofen, Bavaria, Germany. Police investigated around 80 suspicious deaths in 2003 and 2004. 43 victims were exhumed and another 38 had been cremated. The exhumations showed the patients had been killed by a lethal combination of drugs. Letter admitted killing twelve of the patients. The 27-year-old nurse told the court he had acted out of compassion for the dying. In 2006, he was found guilty of 29 murders and sentenced to life.

The Most Prolific Ever

440shipman.png

British physician Harold Shipman may have killed as many as 400 of his patients during his medical career, which would make him the most prolific serial killer of all time. An official audit estimates the number of victims at 236 over 24 years, but the exact number will probably never be known. Shipman was abusing drugs and forging prescriptions early in his career, but went on to treat patients in Hyde, Greater Manchester. Eventually, funeral directors and medical examiners were concerned about the number of deaths under Shipman's care, but an inquiry went nowhere because the doctor had changed medical records after the fact to explain that the patient had been ill. In reality, almost all the patients had been healthy just prior to death. After Kathleen Grundy died in 1998, a suspicious-looking will was produced that left £386,000 to Dr. Shipman. Mrs. Grundy was found to have died of an overdose of morphine. Police investigated the deaths of previous patients, and found many had died of overdoses. Mrs. Grundy's will was linked to Shipman's typewriter, and an examination of Shipman's computer revealed evidence of medical records that were amended after the deaths. He was convicted of 15 murders in 2000 and sentenced to life for each, plus four years for forgery. Shipman proclaimed his innocence until the day he hanged himself in prison in 2004.

Most of the entries in this post were people mentioned in the comments of the previous post on the subject. I have a long list of obscure medical murderers, so there may well be a third installment.

Update: Part three of this series is 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?
May 26, 2017

Nick Briggs/Comic Relief

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.
