Minneapolis, MN – A shocking case has emerged from Minneapolis, where a man has been charged with the murder of his roommate after allegedly poisoning him with the toxic heavy metal thallium. This tragic event unfolded after the 33-year-old victim, Cody Ernst, was found to have lethal levels of thallium in his system, prompting an intense investigation.
The recent charges bring to light a harrowing story of betrayal and toxic contamination that culminated in Ernst’s untimely death in June.
How the Poisoning Came to Light
The ordeal began in mid-May when Cody Ernst began experiencing severe symptoms including fainting, vomiting, dizziness, nausea, and loss of feeling in his extremities. After multiple hospital visits, a detailed metal screening conducted on June 15 revealed a dangerously high concentration of thallium, a toxicity level consistent with intentional ingestion. Ernst tragically passed away on June 22.
“It’s a very slow and painful death. And it’s not OK to have to watch anybody you love die from that. This is not OK,” said Mary Dickison, Ernst’s mother.
According to Fox9, doctors and poison control experts confirmed that the metal could not have entered his body through environmental exposure, strongly indicating deliberate poisoning.
Investigation Leads to Roommate and Evidence Uncovered
Authorities’ investigation focused on Ernst’s roommate, 35-year-old Stuart Hanmer, who is now charged with second-degree murder. Hanmer appeared in court where a bail was set at $2 million with conditions or $4 million without conditions, and he remains in custody at Stearns County Jail.
Investigators uncovered disturbing digital evidence from Hanmer’s phone, including multiple internet searches made in April and May related to thallium. Searches included terms such as “how much thallium nitrate is fatal” and “buy elemental thallium,” indicating premeditation. Purchases of thallium metal and oil amounting to $162.55 were traced back to Hanmer, with deliveries sent to a P.O. box registered in his name.
- Multiple thallium-related internet searches made between April 4–6 and again on May 14-15.
- Evidence Hanmer watched tutorials on how to create thallium sulfate, including the day before Ernst fell ill.
- Hanmer denied involvement, attributing searches to drug use but did not provide a definitive explanation.
Understanding Thallium and Its Dangers
Thallium is a heavy metal historically used as a rodent poison until its ban in the U.S. during the 1970s due to its dangerously toxic nature. Though still utilized in the production of electronics, thermometers, and specialized lenses, thallium remains notorious for its lethal potential and has a documented history of use in poisonings.
The Unanswered Questions and Next Steps
Despite the compelling evidence, the official motive behind Hanmer’s alleged poisoning of Ernst has not been disclosed. The investigation continues as prosecutors prepare their case, while the community grapples with the devastating impact of this tragic loss.
A Call for Awareness and Reflection
This disturbing incident shines a light on the potential dangers of toxic substances like thallium and underscores the need for vigilance in cases of unexplained illness and poisoning.
Key facts to remember:
- Cody Ernst died on June 22 from thallium poisoning.
- Roommate Stuart Hanmer is charged with second-degree murder.
- Extensive digital evidence suggests premeditation.
- Bail set at $2 million with conditions, $4 million without.
- Thallium was banned as a rodenticide in the U.S. in the 1970s but remains toxic and dangerous.
