That Time A Possible Murder Mystery Happened At The South Pole

(Bill Splendor) The Amundsen Scott South Pole Station
Warning: There will be a paragraph addressing suicide in this post.
We all know the trope. Somewhere in an isolated location a group of people gather (mansion, castle, what have you). For whatever reason this group of otherwise strangers must stay together for a period of time (the butler says the roads are washed out, we’ll have to stay until morning). The lights go out, and suddenly someone has died! One of us (at least) could be a murderer, and the rest of us are trapped here!
If we take this trope to its ultimate extreme, we get the unfortunate death of Rodney Marks.
Our location is about as isolated as possible, The Amundsen-Scott South Pole Station during the winter of 2000. The South Pole has essentially two seasons, summer and winter. ‘Winter’ lasts about 8 months from mid-February to early November. In this time conditions make it impossible for planes to fly in and out, meaning that if you visit for winter, you’re staying for the duration. Those that do stay, referred to as Winterovers, are in for constant darkness and temperature highs of -67 degrees Fahrenheit, with lows of less than -100 degrees Fahrenheit. (1)

And a non-zero chance of this Thing.
So What Actually Happened?
When discussing any death, mysterious or not, we should never lose sight of the fact that a real person lost their life. So first, here is a bit about who Rodney Marks was. Marks was a thirty-two year old astrophysicist spending his second (nonconsecutive) winter at the Amundsen-Scott Station. (2) He was reportedly working on the Antarctic Submillimeter Telescope and Remote Observatory project, one of only two Australians stationed there that year. Marks has been referred to as a kind man who got along well with the other forty-nine people wintering at the station that year. In tight quarters there are going to be misunderstandings, but as Marks’ friend Darynn Schneider stated:
(Sic) “…This is where his considerate nature and his kindness would come out. I saw him numerous times make amends in a very nice way for these misunderstandings. He would also say or do something kind for someone having a hard time in general.” (2)
Marks was even a member of the community’s band, Fannypack and The Big Nancy Boys (sorry WHAT) and was engaged to another Winterover, Sonja Wolter. They had met prior to the winter, and she changed her plans to be able to work closer to him. (3) By all accounts, he was well liked, and was sorely missed.
Sadly this brings us to his death. On May 11th 2000, while Rodney Marks was walking between two buildings at the Amundsen-Scott Station, he started to feel ill. He reportedly struggled to breathe at first, and then he began having trouble with his vision and experiencing fatigue. Assuming he had caught something, Marks went to bed early hoping to feel better later. (2)
At 5:30 the next morning, he began vomiting blood. He had increasingly terrible symptoms from that point on; pain in his stomach and joints, eyes so sensitive he had to use sunglasses, and hyperventilation. He was also reported to be extremely anxious, but it is unknown if this was caused by his illness or a result of the other symptoms he suffered from.
Throughout that day, May 12th, Marks visited the base doctor, Robert ‘Robo’ Thompson three times. (3) His symptoms persisted, and at 6pm after he was given a sedative to calm down, he suffered cardiac arrest. He was pronounced dead after 45 minutes of CPR. The doctor concluded that he died of unknown, but natural causes.
However, there was still the issue of his body being in the South Pole. Marks’ body was unable to be moved for the remaining six months of winter. At that time he was flown from the research base to Christchurch, New Zealand.
This All Happened Twenty Years Ago, Why Can’t You Just Shut Up About It?
When Marks’ body reached New Zealand, an autopsy was finally performed, which was possible due to the cold preserving him so well. It was quickly determined Rodney Marks had not died of natural causes. He died of Methanol poisoning.
So first, what is Methanol? It is a highly flammable chemical used in the production of formaldehyde, among other things. Methanol is colorless, but has an odor similar to regular alcohol. The difference is Methanol is highly toxic. 10 mL of the stuff will destroy your eyes, and 30 mL can kill you. For those of us who struggle with the metric system, 30 mL is less than a single shot of liquor. (4)
It is worth a reminder that Rodney Mark’s symptoms began in May, months after that last plane had been at the Amundsen-Scott South Pole Station. As the effects of Methanol poisoning begin between 12 and 24 hours after ingestion, it is impossible for Marks to have ingested it at any time before he arrived at the station, or after meeting with anyone other than the other 49 people he was wintering with. Logically, there are five ways in which Marks could have ingested Methanol.
- He drank it accidentally
- He drank it knowingly in a misguided attempt to get high or drunk
- He drank it knowingly intending to cause harm to himself
- He was given it to drink by someone else accidentally
- He was given it to drink by someone else deliberately, in an attempt to injure him or end his life
First, the accidental causes. It is unlikely that Marks’ or someone else mistook Methanol for alcohol. This was not a dry base in which no one was allowed to drink, they had alcohol readily available. (2) Someone would have had to pour methanol deliberately into drinking glasses to mix these up, or an intelligent astrophysicist drank a vial of unknown liquid at a research station. It is possible, yes, but definitely not the shiny side of Occam’s razor.
As for drinking it to get high or drunk, Marks’ was actually a well documented drinker. He was described as someone ‘who likes to drink, sometimes to excess’ (3). In fact it was reported in some accounts that the doctor originally dismissed his symptoms, believing they were just a result of alcohol withdrawal. Interestingly, he sometimes drank as a way to lessen the symptoms of Tourettes’ Syndrome. Needle marks were also found on his arms, although no illegal substance was present at his autopsy. Thompson later claimed that Marks had admitted to using intravenous drugs in the past, the last one being just before he came to the base.
However, the question that weighs down that theory is why would Marks drink methanol when alcohol (and reportedly cannabis) was readily available on the base? One theory was that he had his own still and accidentally produced methanol, and there were stills run by others found at the base. (3) However, he went to the doctor several times when he felt ill with severe anxiety over his symptoms. If he had just drank a bunch of bootleg hooch before his symptoms began, in a place where alcohol is allowed, it’s extremely likely that he would have told someone this in the day leading up to his death.
As for self harm, I want to be clear in saying that someone considering suicide does not always give warning signs. It can occur even when someone appears to be in a great place in their life, you never know what internal struggle a person is dealing with. The investigator later signed to this case, however, is quoted as saying suicide is ‘the least likely scenario’ in Rodney Marks’ death. (2) He was newly engaged, doing very well in his career, and had close friends on the base. And again, even if he drank the methanol in an attempt to injure or kill himself in a very difficult moment, he tried to save his own life repeatedly the next day. He could have explained what happened at any time, or said it was an accident. The fact that he did not indicates he did not know why he was ill.
If you or someone you know is struggling with suicidal thoughts or ideation, please reach out. The national suicide hotline has changed to the 988 Suicide and Crisis Lifeline, just dial 988 to connect with them, and know that they now can text with you as well if talking is uncomfortable for you. (5)
The only other option remaining is that someone gave Rodney Marks methanol intentionally, likely knowing it would harm or kill him. For most investigators having an exact pool of 49 suspects would be a dream come true, but there’s a reason we still don’t have an answer to what happened in this case. Some list this case as the first murder ever committed at the South Pole, although others say the first one happened at the Vostok Station in 1959. Fun fact, this was an incident in which one scientist lost a game of chess to another, then attacked him with an ax. It is unknown if this resulted in a death, but the KGB banned chess from Antarctic stations for a time. (6)

The devil’s game strikes again.
Investigations in the South Pole are complicated; there is a jurisdiction dispute between America and New Zealand. (7) In any case a New Zealand investigator was put on the case after Marks’ autopsy; Detective Senior Sergeant (DSS) Grant Wormald.
DSS Wormald has stated that the agencies involved with his investigation, namely the Raytheon Technologies Corporation and The National Science Foundation, have been less than helpful. They reportedly did not disclose to him the names of everyone on the base at the time of the death, and he even suspects some employees have been warned away from answering questions. (7) He eventually convinced them to send out surveys to the 49 others stationed there, but they were voluntary and few were returned.
Rodney Marks was memorialized by a plaque in the South Pole, and a mountain in the Worcester Range was named after him. His family now say that they believe they will never know what truly happened to him.
I believe what truly pulls me into this case is how easy it feels to solve. The scene is isolated, the suspects numbered, the cause of death all but certain, and yet no motive is known. There has been only one accusation, and that is of Robert Thompson, the doctor who assisted Marks and declared him dead. (2)
William Silva, a physician working at another antarctic station, reviewed Thompson’s medical notes that day. He noted it was off that Thompson did not use a blood analyzer he had access to, especially when Marks’ symptoms were unexplained. The blood analyzer would have easily shown his high levels of methanol, and steps could have been taken to neutralize its effects. Thompson did respond to this initially, he stated the machine was difficult to use, and he was too busy caring for Marks to use it, although he did take blood that day. In fact he supposedly took blood directly from an existing needle mark on the patient’s arm, which investigators found odd.
Silva disputed Thompson’s explanation, saying the machine, known as the Ektachem, was easily accessible, and not particularly hard to use. Thompson ‘fell off the grid’ later in the investigation, and has not responded again. He was never charged. For the record I could believe that a doctor was too busy trying to calm down a panicked man if he was the only physician available to help, but I do not see why he wouldn’t have used it after Marks’ death. He ruled the death as natural causes at the time, only to be proven wrong six months later.
I cannot make up my mind on this one. I would love to hear from you all. Do you believe Marks was murdered? The victim of a freak accident? Am I missing a possibility? This is one of the cases that leave me feeling like I’ve read half a novel that was never finished.
Until Next Time,
The Rabbit
