Poisoning People for Fun and Profit—Part 16: Antifreeze



Antifreeze, (Ethylene Glycol) has been the weapon of choice in some recent high profile domestic murders. In earlier posts, I've concentrated on the poisons of classic mysteries that were more common in a 19th or 20th century home than in a contemporary one, but now I'm going to move on to some more modern toxins.



The Advantages of Antifreeze as a Murder Weapon


For the contemporary murderer, antifreeze has a lot of plusses.


1) There's nothing suspicious about having it around.


You can always keep the stuff in the garage with the intention of using it to protect the car for a ski trip or winterize that mountain cabin. (Some people like to put antifreeze in the toilets of summer cabins to avoid breakage from hard freezes. Unfortunately, pets drinking from the toilets the next summer may have to be rushed to the vet. Beware: Ethylene Glycol is toxic to pets, too.)

2) The victim won't suspect a thing.


Antifreeze has a sweet, not unpleasant taste (unless a bittering agent has been added, which is now mandatory in some countries and states.) But if the unbittered kind is put into a sweet beverage like sweet tea or a whiskey sour, the victim won't have a clue that anything is amiss.
It's undetectable in sweet tea


3) It works fast.


Unless an antidote is administered within an hour of ingestion of a lethal dose, a human victim's fate is sealed (dogs and cats have digestive systems that give them a little more leeway.) The usual anti-poison measures, such as charcoal, gastric lavage and bicarbonate of soda will not work and can make matters worse.

4) You can blame the victim.


The initial symptoms of antifreeze poisoning appear to be the result of overindulgence of alcohol.


5) Death usually doesn't appear suspicious.


Most antifreeze poisoners have been caught because of snitches or mistakes by the killers. The victims appear to have died of heart attacks or kidney failure, so there's no reason for an autopsy.

 The Symptoms


Ethelyne Glycol poisoning symptoms occur in three stages.

 
The victim will first appear drunk
1) Intoxication—the victim appears to be drunk, with slurred speech, uncoordinated movements, confusion, and drooling.

2) Elevated Heart Rate—plus hyperventilation, muscle spasms, and heart failure. Sometimes the victim dies during stage 2 of what appears to be a heart attack.

3) Kidney failure. Often indicated by severe lower back pain—and eventually, death.

Treatment


So how is this kind of poisoning treated if it's caught it in time?

The treatment for antifreeze poisoning
The antidote of choice is pharmaceutical grade ethanol given intravenously, but, if your character can't get to a hospital, it’s handy to know that the victim can also be saved by administering a strong oral dose. In other words, a number of good, stiff drinks. Plus a lot of water.

The reason this works is that the body prefers pure alcohol to the antifreeze and will absorb it instead. So the victim may live, but he'll have one bear of a hangover.

A Few Well Known Cases of Antifreeze Poisoning


In 2013, a mother-daughter team in Missouri, Diane and Rachel Staudte, were convicted of killing two relatives and attempting to kill a third with antifreeze cocktails. They might have got away with it if a nurse in the hospital of the third victim hadn't told the police that the women seemed way too happy for members of a grieving family.

NBC's Dateline recently ran a 2-hour special on the Holly McFeeture case. Ms. McFeeture was convicted of poisoning her fiancé Mathew Podolack in 2006 with antifreeze-laced iced tea over a period of months. Because the poisoning was slow, he didn't know anything was amiss until it was too late. Unfortunately, by the time he went to a doctor for lower back pain, his kidneys were already failing. 


The "Black Widow" poisoned her husband with antifreeze in Jell-O
One of the most notorious antifreeze poisoners was Stacey Castor, "The Black Widow" who poisoned two husbands with Jell-O made with antifreeze. She then poisoned her own daughter and tried to pin the murders on the young woman with a fake suicide note. Thankfully, the daughter survived.

In 2014, Dr. Ana Gonzalez-Angulo was sentenced to 10 years in prison for the attempted murder by antifreeze of her lover Dr. George Blumenschein in a Fatal Attraction style love triangle. She'd laced his coffee with the stuff. He survived, but lost 60% of his kidney function. Now if he'd taken his coffee with no sugar…

In 2008, after a decade of legal wrangling, Mark Jensen was found guilty of the slow poisoning of his wife with antifreeze. She had left a letter with a neighbor saying that if anything happened to her, she feared her husband was trying to kill her, but this was kept out of court as "hearsay evidence" until the last minute. The defense argued that she was slowly committing suicide, but that seems unlikely, since suicide tends to be a spur of the moment thing rather than a long drawn out process. Also, Jensen admitted to the murder to a jailhouse snitch.

What about you? Have you read any mysteries that featured antifreeze as a murder weapon? Are any antifreeze plots planting seeds in your heads? 


Here's a list of all the posts in the poison series


ABSOLUTELY FREE!!


Free on all the Amazons from August 4th-August 8th

a short book of short stories


Humorous portraits of rebellious women at various stages of their lives. From aging Betty Jo, who feels so invisible she contemplates robbing a bank, to neglected 10-year-old Maude, who turns to a fantasy Elvis for the love she's denied by her patrician family, to a bloodthirsty, Valley-Girl version of Madame Defarge, these women—young and old—are all rebelling against the stereotypes and traditional roles that hold them back. Which is, of course, why Grandma bought that car…



Great for your driving commute!

  1. I guess that makes Jello shots in dive bars a definite no-no. :-(

    2. Champagne cocktails at the Ritz? Sounds like upscale murder à la Grace Kelly and Hitchcock.

    3. Ruth--Hmmm. Lots of possible plots with this one aren't there? The real-life antifreeze murders seem to have happened in the redneck community, but that doesn't mean that the 1% can't perpetrate a few of their own. One of those Grand Prix drivers might have some antifreeze in the trunk for a little jaunt over the Alps, right? Great idea!

  2. You have some very interesting blog topics. I love coming over to see what you are writing about, but I wonder if I should post a disclaimer on my blog reading and Google search history saying I am a writer doing research--not a serial killer. ;-)

    1. Valerie--If the FBI starts looking at my search history, I'm doomed :-) Originally this was only going to be eight posts, then ten, then fifteen, but I keep finding more fascinating poisons. All through those Google searches. No, officers, those holes in the back yard are for the new sewer pipes not the bodies....Haha. Let's hope it doesn't come to that.

  3. This is most interesting. I see this in Lifetime movies sometimes and it gives me the creeps that these people haven't a clue that they're going to die within the hour. How terrible. An additive is a great idea for humans and pets.

    1. Patricia--It is something that shows up in Lifetime movies isn't it? And even in real life, it seems to be a "domestic" murder weapon. I guess because a cook can add it so easily without being suspected.

      I agree that the bittering additive is a big help in keeping pets (and family members) safe!

  4. Brilliant! Dear CSIS, FBI, Homeland, etc...I just REALLY like grape jello...yeah...

    1. Carolyn--Jell-O is the perfect vehicle for Antifreeze poisoning, since that super-sweet, slightly artificial flavor fits right in. And if the victim has any kind of pre-existing medical condition, they often won't even bother to call in the CSI or FBI folks. No autopsy at all.

  5. Yes, you've got me working plot ideas with anti-freeze murders - and I don't even write mysteries!

    1. Jennifer--I know. This one really gets the wheels turning, doesn't it? Because it's undetectable and very likely to look like "natural causes." Hmmmm.
