Math Caught A Serial Killer

Kristen Gilbert was nicknamed the “Angel of Death” because so many patients happened to die during her shifts. No one saw her doing anything wrong, and there just wasn’t any physical proof in post mortem examinations… but many of the patients who went into cardiac arrests didn’t have health problems that should result in heart failure. Some were even young and physically healthy. But without hard evidence, is it even possible to determine whether a doctor or nurse is actually killing patients?
The data revealed a shocking pattern of elevated patient death rates during Gilbert’s shifts at the Veterans Administration hospital, but that still didn’t prove anything beyond a reasonable doubt. The thing is… it doesn’t necessarily HAVE to. In the case of Kristen Gilbert, math identified the possibility of a serial killer’s existence and then let a full investigation do the rest. Gilbert is serving four life sentences plus an additional 20 years, and dozens, if not hundreds, of lives were saved by getting her away from patients.
The state spent $1.8 million defending Kristen Gilbert in a trial in which she narrowly escaped a death sentence. But that trial never would’ve happened at all without math.

Gotta agree with the Judge on this one. Humans like patterns. If that graph was in front of any regular person, there'd be no question in their mind Gilbert was guilty, but graphs can be misleading unless you understand how data works (and even then).

[@jazzabighits4473]

It's not really misleading if you can read an X and Y axis (or the labels on them) lmao. Literally primary school stuff

[@RisqueBisquet]

​@@jazzabighits4473 No, that's precisely why it *is* misleading. Data in isolation doesn't take in extraneous factors. "Correlation is not causation" can be difficult for people to process. Fun fact, there's a strong correlation between drownings via household swimming pools in the USA, and Nicholas Cage staring in leading roles in movies. Does this mean Nicholas Cage likes to spend his time off-set murdering people in pools? Probably not. One chart without proper analysis can lead you to very wrong conclusions.

[@jazzabighits4473]

@@RisqueBisquet Making a terrible strawman doesn't seem the right way to argue it dude. I'd argue that the thing that correlates closest to household swimming pool drownings in the USA is living in the USA and actually having a household swimming pool. Of course, this chart failed to mention if any other people were working the same shifts as her, because it could've just as easily been someone else. However, it is quite obvious that either her, or somebody during those shifts, was doing something dodgy. Nothing misleading about it (and it turned out to be correct in the end)

You know what's really messed up? Is that the schizophrenic patient, if for example he knew that it was this lady doing this to him, and for all 3 consecutive heart attacks, he was like "She's doing this to me! She's trying to kill me!" they would just chalk it up to him being crazy. Because once you're labeled as crazy, anything you say or do is just gonna fit that mold. Really sad honestly.

Can hardly believe that he was fully justified in his concerns there, in a literal hospital, but the proof’s in the pudding now.

[@Lazerstory]

I agree that it's a shame if patients with paranoid thoughts (like schizophrenic patients) aren't trusted even when they tell the truth, but I don't think it's necessarily a case of doctors who would "label them as crazy" (because crazy isn't a medical term by the way, it's a stigmatizing term used towards mentally ill, usually psychotic patients that is patients that lose contact with reality). Paranoid patients can have delusions about persecution (people trying to assault or kill them...), so it's no surprise that doctors who have a lot of patients to care about don't pay attention everytime a patient with those kind of delusions says that a nurse is trying to kill him. It's a shame, but it's not the doctors' fault in my opinion. It's like if a depressive person says that they have nothing valuable in their life, most of the time it's not true so doctors won't act like it is (but the feelings of despair are real don't get me wrong, just like the schizophrenic's feelings of persecution are real).

[@chankfreng]

We need to be careful with claiming to use statistics to “prove” any causation. In this case, more evidence was found in order to make a conclusion. If you used only correlation, you can imagine that you could just as easily have found a disproportionately high death rate associated with that police officer. It would also be incredibly easy to frame someone with a crime if statistically significant correlation was sufficient to convict someone. Statistical analysis often only tells you where to look; you still need to investigate deeper and/or perform an experiment to reach a useful conclusion.

[@ghetoknight7801]

bruh so well explained, I'm seeing people arguing that those statistics were solid proof, without acknowledging that by that logic you could easily claim the whole hospital was a criminal organization, or the police man was a psychopath, even though it's not true that in itself is evidence that outlandish statistics wouldn't reveal the answer

It's important to know that math itself isn't deciding who's innocent and who's guilty. Like many things created by humans, Math is a tool, and tools can be used by whoever knows how to get their hands on it. It can be used correctly and honestly, or it can be used by someone with less honest intents and not much interest in learning how to use it properly. Math can really lead to some amazing futures and feats, but it can also cause horrible tragedies to happen. That's why I think it's really important for math to be show and shared to everyone so anyone can understand and can call out whenever someone abuses it. Sadly schools aren't doing a too good of a job encouraging younger generations to learn and be curious.

[@voidnimbus]

every living person has an history of mental illness

[@angrynoodletwentyfive6463]

When a story says somebody has a "history of mental illness" they usually do not mean anxiety or depression. Yes those are mental illnesses, but they are not mental illnesses that are relevant to what is going on. Sort of like how when they say "is there a doctor in the house" at a resturaunt they are not asking for the guy who studied theatre for 20 years eve though yes he would have a doctorate it is known that the mean a medical doctor. Similarly A "history of mental illness" is usually talking about skitsofrenia, Bipolar Disorder, Psycopathy or Another serious mental illness that actually would contribute to a mental state in which the person would do the thing they did. An Anxiety disorder is pretty much never going to contribute to the mental state required to commit a crime. To be clear having a serious mental health condition such as those mentioned does not make a person automatically "Dangerous" but the fact that people with these conditions are sometimes compelled by the mental state created by their disease to commit horrific crimes is not "made up" either. It is a case of a few exceptional individual cases creating stigma for the entire group, but just because most skitzofrenics are completely harmless, does not mean that the condition of skitsofrenia did not contribute to the crime committed by a one skitsofrenic individual.

This is a good reminder that a lot of what we take for granted -- math, DNA, fingerprints, ballistics, blood spatter, bite marks, drug dogs, etc -- aren't as foolproof as we have been led to believe -- and that while they can *help* us solve crimes, if not used carefully, they can be *also* abused to convict innocent people as well.

7:30-7:39 Makes sense. Epinephrine is also naturally produced, notably during stress.

I live in Northampton mass and I'm very familiar with this story. Thanks for giving it the treatment it deserves.

[@GuyInTheRainbowShades]

Nice! I’m from mass too! I clicked on the video thinking it would just be a regular v sauce vid, I was mind blown when they showed the picture of downtown! I used to love mama iguanas as a kid, and I had teriyaki chicken from noodles last night!

Love this content, wish I had the brain for math. But I miss Mike and Jake.

[@dragonick2947]

I think they have their own channels where they talk about their own relevant topics, unless that's changed.

[@darolaho]

I love the real life videos. While the thought experiment/games were entertaining they all kinds mixed together i never knew what videos i had already watched

[@mexrus1918]

I love this math in trail series, keep it going!

[@michaeld4861]

Insane that she was even allowed to be a nurse in the first place with the heinousness of her previous crimes.

[@RespecterAlexander]

Nurse: *kills people and avoids being caught* Math: I’m gonna put some dirt in your eye

[@gigiobigio0002]

I understand everything, math and stuff, but do u know how creepy it is when ur sick and a nurse is just straight trying to poison you while u cant do anything about that?

[@pasinduravimal]

Man, you are making me fall in love with maths and science (and with VSauce2)! Every punchline you make gives me goosebumps!

[@bobbyshores]

Wow I really really liked your spin at the end. Made it about how math was used to prevent any more deaths that almost certainly would’ve happened. The part about them playing footsie during a code put a big lump in throat because I’m just imagining if someone I loved was dying on that table and instead of trying to save them they were trying to be cute and playful 😡 still though, amazing video!

[@FreeDomSy-nk9ue]

Awesome video. I love this series I hope it never ends...

[@mrmistermelom]

He’s like the teacher explaining why math is an important skill

[@prajwalchauhan6440]

I love these new videos relating crimes and maths but i really miss those old game theory related videos... They were so much more fun and mathematical

[@TCcool283]

What my teacher thinks I will use math for in the future:

[@survivedandthriving]

If it is true that the facility where Gilbert worked had the same overall death rates as other, similar facilities, imagine how fantastic the rest of the staff there must be. They had an active killer in their midst, but at the same time the rest had such low death rates that they counteracted actual murder.

[@DeJay7]

I see that nearly everyone in the comments seems to really enjoy this type of videos from Kevin, but while I also like them, old type videos are still my favourite. Would really enjoy one of those again, we've had enough.

[@titiwa632]

10:50 I think life in prison is a more appropriate penalty to this case than death penalty. Why end her suffering in an instant when you can make her live in prison?

[@friendlyneighbourhoodrat]

Exactly..!

[@Alex-yj9xl]

She'll still be in prison for a long time, and death penalty is scarier for the person.

[@asqwerty257]

Great Video! I do have one question though. How did they know it wasn't another nurse working the evening shift.

[@pewpewdragon4483]

Really like the ending message in general; we don't always have to solve the problem, just make the problem be known.

[@alexross1816]

I just started watching Brooklyn 99 and I thought you said the officers name was “Jake Peralta” and I almost spat out my drink.

[@inklink8471]

This sounds oddly similar to a guy who committed the same crimes here in Germany. Niels Högel. He committed them the same way, but was charged with more than 50 cases of murder and attempted murder.
