Murder of a Russian Crypto Investor Couple: An Israeli Arrested in Dubai

Crypto was supposed to be a revolution. It has become a magnet for criminals. Hackers, scammers, kidnappers. Now, killers. Physical violence has caught up with the crypto industry. Proof with this chilling case. A Russian investor couple found dismembered in the Dubai desert. And an Israeli private detective caught in the police net. Welcome to the new frontiers of organized crime.

The detective and his shadows: Michael Greenberg arrested in Dubai

Dubai, three months ago. A violent raid by the Emirati special forces. They evict a man from his hideout. His name is Michael Greenberg. Israeli private detective based in Thailand. His agency, Mike Green Private Investigation, has been operating in Bangkok for twenty years. For several weeks, no sign of life. His family worries. Then confirmation comes: he is detained. Authorities remain silent on the charges.

Why him? The Russian investigation exploited the phones of the eight suspects already arrested. Crucial information was discovered. Greenberg is not accused of killing the Novak couple but of having connections with the killers. Did he organize? Advise? Facilitate? The mystery remains. 

Greenberg is not suspected of committing the murders but of having links with the perpetrators. The evidence discovered in the phones of the suspects during the Russian investigation led to his arrest, note Ynetnews.

His past catches up with him. In 2021, he was already suspected. He allegedly planned the kidnapping of a Taiwanese businessman in Bangkok. A ransom attempt of 2 million dollars. He had escaped the net. Not this time. The noose has tightened.

Rendezvous with death: the villa trap and the empty crypto wallet

We go back. October 2025. Roman Novak and his wife Anna live in Dubai. He is a former Russian convict. In 2020, he served six years for fraud related to crypto assets. Released in 2023, he launched a fundraising. Through Fintopio, a transfer app, he raised about 500 million dollars. Many cried scam. Some investors accused him of disappearing with the funds.

On October 2, their driver dropped them near a lake. Hatta area, Oman border. A meeting with “potential investors.” In reality, a trap. They are lured into a rented villa. Their crime? Having cryptos. The kidnappers want one thing: access to Novak’s digital wallets. The key to the supposed fortune.

Problem: the wallets are empty. Completely empty. The criminals realize they have kidnapped a man without a satoshi. So they act. The bodies were found in November, buried in the desert, dismembered. The suspects fled to South Africa before disappearing. Tragic irony: Novak may have already been ruined. But his killers believed it only after killing him. The empty crypto wallet sealed his fate.

The Novak case in numbers

• 500 million dollars raised by Novak, which vanished;
• 8 suspects arrested before Greenberg’s arrest;
• October 2, 2025: date of the couple’s last appearance;
• 2 million dollars: ransom demanded during a previous kidnapping involving Greenberg in 2021.

Last year, France was shaken by a wave of kidnappings linked to cryptos. Relatives of exchange bosses. A Ledger co-founder. The arrests followed one after another. But are they enough? As long as the blockchain promises anonymity, men will continue to die for private keys. Violence has become a business like any other.
