"New information revealed in court sheds light on the connection between three hazmat scenes in the Madison area this week."

"According to Dane County Assistant District Attorney William Brown, the suspect, Paul Van Duyne, attempted to poison two former love interests with cyanide.... During a bail hearing for Van Duyne's co-defendant, [Andrea] Whitaker, Brown described an elaborate scheme.... Brown accused Van Duyne of breaking into a woman's car while she was in the parking lot of Costco in Middleton and putting cyanide in her water bottle.... Brown said Van Duyne attempted a similar cyanide poisoning with a separate woman in Rock County. He said in this case, the woman's gym water bottle was poisoned with cyanide, and a powdery substance was located in her car.... When Van Duyne was arrested, Brown said he called Whitaker and instructed her to remove a variety of items from his home that Brown said would implicate him in the crime.... He also said Whitaker's search history included phrases such as 'cyanide lethal dose' and 'Does potassium cyanide powder go bad?'... 'It does appear that this defendant [Whitaker] and Van Duyne have started dating and apparently created this plot to kill his ex-girlfriends by poisoning them,' Brown said...."

From "Prosecutor: Multiple hazmat scenes linked to elaborate scheme to poison man's former love interests with cyanide" (WKOW).

Now, we understand why some streets around here were blocked off as hazmat scenes.

I'm trying to picture how a plot to kill a man's ex-girlfriends gets created. These are real people so I won't publish my musings.

Geez Louise!

I'm wondering who hatched this scheme. Isn't poisoning famously "the way women kill"?

Jamie said...

Oh hey, One Eye, looks as if we had the same thought.

mezzrow said...

What's the antonym for "star-crossed lovers"?

Old and slow said...

Sounds like a Coen brothers movie.

Rusty said...

Musta been some pretty weird, kinky stuff to want to off your EX- girlfriend.
And the mug shot looks exactly like you'd expect a psychopath to look like.

One Eye said...

"The way women kill" - see the 1987 film "Black Widow". And we've come full circle to David Mamet.

Should have just ghosted the ex’s.

Looks like he tried to do just that.

Next time I go to Middleton Costco, I am going to think about how this guys girlfriend broke into someone's car and spiked their water with cyanide there.

I used to think some folks shopping there were a little odd, now its proven.

Ampersand said...

Now that I think of it, poisoning, though complex, seems like a pretty effective way to commit homicide. But it's rare. In 2017, the FBI reported that out of 15,129 total murder victims, 13 were killed by poison.

Robert Marshall said...

"When Van Duyne was arrested, Brown said he called Whitaker and instructed her to remove a variety of items from his home that Brown said would implicate him in the crime"

Is that saying that while he was in custody ("arrested"), he phoned the other defendant, asking for help in concealing evidence? That seems awfully careless, as a matter of criminal tradecraft! Did he expect the police not to listen in on his phone calls? Or am I misunderstanding what WKOW reported?

I think you just about got it there, Bob.

These two don't exactly exude MENSA vibes.

Does cyanide have a "legitimate" use? Do you just go to the drugstore and say "I'd like some cyanide, please?"

Laslo Spatula said...

When you want the cookies to have a touch of bitter almond flavor.

What can I say? I often bake for strangers.

Yes they are! And this guy was looking for a love to call his own, he thought he’d flounder, but he was wrong. She wasn’t a keeper and he should’ve just moved on.

There is some thought that progressive consumption of a poison can adapt a body to larger doses. This is true of Fentanyl that functions as a respiratory suppressant, in conjunction with neutralizing drugs. Could have had a cyanide drip.. Your experience may vary.

Just one more reason not to drink bottled water.

How to abort a "burden" is a religious documentary of liberal license exercised in progressive sects. He forgot to request, purchase sanctuary certification to sequester the evidence.

It gave them a shared porpoise.

MadisonMan said...

I've been following this on Reddit, and it's been quite a thing. I'm not sure how anyone thought this would work.

Old and slow said...

Cyanide does have a legitimate use. I used to have a couple pounds of it. Look up “bombing” in reference to jewelry and metalwork. It’s a great (and fast) way to do gold plating. You fumes can be deadly, but you’d be surprised how casually it gets used with just a basic fume hood.

n.n said...

A Planned Matrimonyhood? His Choice. All's fair in lust and abortion.

gilbar said...

"poison two former love interests"

NO! you CAN'T show your love, by killing.. That's Just Wrong*
On a Practical Note..
Had this guy, EVER tasted cyanide? Not many "former love interests" are going to have SUCH Little taste, that they'd willingly drink enough bitter water.
[has gilbar EVER tasted cyanide? of COURSE he has..Haven't YOU?]

Protip: if your new "love interest" wants you to show your "love" by killing off your former love interests, she's not the one for You.. there WILL BE future problems when you end it (OR, when she ends it)

Just Wrong* this message was brought to you by MORALITY

Sounds like a big nothing Burger as far as a hazmat site goes. It's not like they were meth labs.

My grandson lives in student housing on the next street from where this guy lives. Their neighborhood chat group has been going crazy. Lots of hazmat suits running around causes more excitment than a beer party

Poisoning someone to kill them is literally the most feminine say to kill someone. The Medeci women loved it.

In other words, and pardon them...what an effing pussy.

Poisoning former lovers...so shrimple a cavefish can do it.

Skeptical Voter said...

Well this situation cries out for the return of Laslo Spatula. But I look at the mugshot of the guy. He looks like a sore loser--but mostly a loser. And I can't think too much of his current girlfriend either. As I said he looks like a loser.

Ron Winkleheimer said...

"That seems awfully careless, as a matter of criminal tradecraft! "

So is using a computer linked to you to do research on how to commit the murder. And for that matter, the cops are going to link the guy to his two ex-girlfriends and that is going to be a red flag right there.

RideSpaceMountain said...

Oyster yer honor? I just met her! Oh the humanatee...

boatbuilder said...

Old and Slow--I just looked up "cyanide." Now you want me to look up "bombing." Are you sure you're not an FBI plant? ;^)

boatbuilder said...

Boyd hoping that nobody knows what a mackinaw is...

Yancey Ward said...

"Did he expect the police not to listen in on his phone calls? Or am I misunderstanding what WKOW reported?"

I was an alternate juror on a felony murder case once and the defendant wrote letters from pre-trial detention to his girlfriend in which he admitted to participating in the robbery and the shooting.

Aggie said...

All of this is good fun, but.... what about the shootings over the weekend, and the capture of the killer with the 'interesting' history? And what's this I read about the murdered former Speaker's home being burgled 4 days after she and her husband and the dog were killed? Things are awfully quiet about this - I would have thought the interweb and airwaves would be blowing up on it, but....... nope. You only get the news when you vote the right way.

RideSpaceMountain said...

Cyanide is much too fast. If you want them to suffer you use arsenic, and if you really want them to suffer to take the Americium-241 out of a smoke detector and get it into their body (usually food) somehow to allow its alpha-decay (and slight gamma emission) to slowly irradiate them from inside out till they accumulate a lethal whole body dose. This process is also rather slow, and is very easy to forensically detect so I don't mind sharing. It's disturbing that I know this, but my dad was a special-weapons officer in SAC (and the source of most of my nuclear weapons knowledge), so thanks dad...I guess.

Speaking of poisoning and the Medicis, it is widely suspected though not proven that one of the last Valois kings of France, Charles IX, was poisoned by arsenic, possibly by his own mother, Catherine De Medici, in a botched plot to kill Henri IV De Bourbon. Alexander Dumas is widely sourced as the origin of this theory -which many consider apocryphal - although he himself was only transcribing well-known popular understandings from before his own time. And it is well-known the Medicis loved poison.

The ultimate lesson? Never trust a Medici, and be suspicious of missing smoke detectors.

Iman said...

He thought he’d found a snapper, but she turned out to be too crappie, even for him.

Iman said...

Even worse, she had no sole…

Dr Weevil said...

Ampersand (7:50am):
Poisoning is "a pretty effective way to commit homicide", but it's rare because it's easy to prove. I once read somewhere that chemistry and forensic science have advanced so far that it's impossible to get away with poisoning someone, unless the authorities are careless or crooked. In other words, there are no longer any undetectable poisons. To put it another way, it's not just Americium-241 that's "very easy to forensically detect", as RideSpaceMountain says at 10:49am.

As for all the people making terrible fish puns: please take them over to Ace of Spades, where they are more appropriate and appreciated.

Dane County Court Commissioner Karine Kattanach stomped her tiny liberal hoof and pouted: 'thees was such a horrible crime, I'm gonna give him $750K bail.' What a stupid, stupid, stupid woman.

FullMoon said...

Recently watched 2 true crime stories of husbands poisoning wifes.
Each administered small amounts over a period of time. Enough to be hospitalized for unknown "illness" each time.
Eventually enough to kill.
After numerous previous visits, cause of death unknown.
Eventually caught, though.

Where can you buy cyanide?

RideSpaceMountain said...

Cyanide is much easier to procure overseas than here. It used to be you could acquire special occupational licenses (jewelers for instance) and that was sufficient for mail delivery, but no longer. Honestly, the easier way now (in Western countries) is to simply make it from cyanogen-bearing plants like apple seeds, plum seeds, or manioc. It is not hard, but requires patience and the intelligence to extract it safely without killing yourself. I also believe that high level pest control companies can acquire it, but once again, heavy oversight...

Frankly, it would be far easier to just buy a pufferfish (fugu in Japanese) and extract the tetrodotoxin (TTX) from the liver or ovaries. It would have to be fresh, but a very small amount of TTX is sufficient to kill, and the effects are irreversible.

People say I scare them...lol😇

BarrySanders20 said...

Wow they sure are getting judgey in Trump's Madison all of the sudden. Since when is it wrong to try to poison your multiple ex-girlfriends? And "poison" is such a loaded, discriminatory term. How about "chemically enhance?"

stunned said...

So-called peacekeepers.

BG said...

Speaking of cyanide...I was shopping for the cheap table salt today. I don't buy it very often because we don't use it very much. So it's been a while. As my habit, I looked at the ingredients. What the heck is yellow prussiate of soda? So I immediately looked it up on my phone. This is what came up: "Prussiate of soda, also known as yellow prussiate of soda or sodium ferrocyanide, is a yellow crystalline compound used primarily as an anti-caking agent in salt. Despite containing cyanide, it is considered to have low toxicity because the cyanide is tightly bound to iron atoms and does not release free cyanide under normal conditions." (Bold is mine.)
I DON'T CARE IF SOMEONE CLAIMS IT HAS LOW TOXICITY.
I spent money on the salt that doesn't have it even though it cost a lot more. Who thinks up all the crap they put in food these days?

Crazy People are Dangerous. They've been let off the leash in Democrat areas, lots of uncivilized ( anti civilization ) behavior has been tolerated and praised and on TV. Is it too late to close the barn door ? I say yes. Time to build some extra jails.

Lazarus said...

"All my exes live in ... well, they don't actually live anymore ..."

The say the murderers in Agatha Christie books used poison. It was cleaner than gunshots or stabbings, and also probably allowed for the inclusion of more suspects.
