The son of a Ukrainian deputy mayor was kidnapped and murdered by a classmate because of his cryptocurrency assets. The suspect forced him to reveal his wallet's password before setting the house on fire to silence him.

In late November, a car arson and murder case related to cryptocurrency occurred in Vienna, Austria. Local police disclosed that two suspects were recently apprehended in Ukraine. The victim was Danila Kuzmin, the 21-year-old son of Sergei Kuzmin, the deputy mayor of Kharkiv, Ukraine. Police investigations revealed that the suspects' motive was to obtain the victim's cryptocurrency wallet passwords. While studying in Vienna, Danila had revealed his father's identity and information about his family's cryptocurrency assets to one of the suspects. Subsequently, Danila was attacked in the underground parking lot of the Sofitel Hotel in Vienna, forcibly taken away, and held captive in the car for several hours, during which he was continuously beaten and tortured until he handed over the passwords to two cryptocurrency wallets. Vienna police confirmed that large sums of money were subsequently transferred from Danila's cryptocurrency wallets. After emptying his cryptocurrency assets, the suspects abandoned Danila in the back seat of the car and set it on fire. The burned Mercedes-Benz had Ukrainian license plates and was registered under the names of his family members. The two suspects were subsequently identified as 45-year-old Oleksiy Agoyev, a former Ukrainian customs official, and 19-year-old Bogdan Reynzhuk, the stepson of Oleksiy Irazhuk, the Ukrainian ambassador to Bulgaria. Police seized a large amount of US dollars in cash from the suspects during the arrest; Agoyev was carrying nearly $90,000. The case is still under further investigation.
