A case headed to the Seoul Eastern District Court is drawing attention not because it involves a new token or a market collapse, but because of how violently a failed Bitcoin venture allegedly spilled into real life. Prosecutors say a 39-year-old man tried to kill his business partner after suffering steep losses tied to a Bitcoin investment, with the alleged poisoning dated to Nov. 23, 2025 and a first court hearing set for March 10, 2026.
Authorities describe the accused as “Mr. A” and the victim as “Mr. B,” and the alleged incident took place during a meeting near Seokchon Lake in Songpa-gu, Seoul. According to prosecutors, Mr. A slipped methomyl—described as a highly toxic insecticide banned in South Korea—into Mr. B’s coffee, after which Mr. B lost consciousness and later spent three days in a medically induced coma before regaining consciousness and continuing treatment.
What prosecutors say happened and why
The prosecution’s theory is that the motive was financial and tied directly to a partnership that had been operating since 2022. They claim Mr. A lost about ₩1.17 billion in a Bitcoin investment—roughly $810,000 to $880,000 by their conversion—and tensions escalated when Mr. B took control of company funds after the losses.
Prosecutors also allege premeditation, pointing to an October 2025 purchase of methomyl online from China. They are presenting that timeline as evidence the act was planned rather than impulsive, which is central to an attempted murder charge.
Methomyl’s legal status adds a second layer to the case. The filings note the substance has been banned in South Korea since 2012, with distribution and use fully prohibited from 2015, which prosecutors say supports additional pesticide-control-related charges alongside the attempted murder count.
Why this case lands inside a broader crypto enforcement moment
Even though the crime itself is not a “crypto hack,” it arrives while South Korean authorities are publicly emphasizing that digital assets are increasingly intertwined with criminal investigations. The reporting you provided cites that virtual assets accounted for 15.8% of criminal proceeds seized in 2025, and notes that courts have upheld seizure of Bitcoin held on exchanges while procedures for handling confiscated digital assets continue to evolve.
From a market-structure standpoint, the episode is a sharp reminder of where risk concentrates when people operate through informal, off-exchange arrangements. When disputes involve private custody, opaque fund control, and concentrated losses, the downside is not only financial—legal and personal consequences can escalate quickly, and subsequent seizures or custody orders can materially affect counterparties’ access to assets.
The March 10, 2026 hearing will be the next concrete milestone, testing claims of motive and premeditation and putting crypto-related financial evidence under courtroom scrutiny. For custodians and compliance teams tracking South Korea, the case is another signal that enforcement and judicial practice around crypto-linked proceeds and evidence handling is becoming more active and operationally consequential.
