Michael Coberg, a former Los Angeles County Sheriff’s Department deputy, has been sentenced to 63 months in federal prison for his role in a violent extortion scheme that targeted cryptocurrency holders.
Coberg pleaded guilty to conspiracy to commit extortion and conspiracy against rights, admitting he used his law enforcement position to intimidate and coerce victims into transferring digital assets.
Operating alongside crypto entrepreneur Adam Iza, Coberg received at least $20,000 per month to enforce the scheme, including incidents involving armed threats and forced detention in October 2021.
Inside the Operation
At the center of the Crypto extortion scheme is Adam Iza, founder of the crypto trading platform Zort, who styled himself as “The Godfather.” Authorities say Iza leveraged both wealth and influence to run a coordinated effort to extort victims, often relying on insiders like Coberg.
According to court filings, Coberg was paid at least $20,000 per month for his role in the Crypto extortion scheme, effectively acting as muscle in disputes tied to financial disagreements.
The most striking incident occurred in October 2021, when Coberg participated in the forced detention of a victim identified only as “L.A.” The victim was taken against his will and transported to Iza’s residence, where the Crypto extortion scheme escalated dramatically.

There, prosecutors say, Iza recorded a video while coercing the victim to transfer $127,000. Coberg stood by during the ordeal, reinforcing the threat and ensuring compliance a key moment that prosecutors described as central to the Crypto extortion scheme.
Violence and Coercion
The situation did not end there. In a chilling escalation, Coberg later accompanied the victim to a firing range, where Iza allegedly held the individual at gunpoint. Under duress, the victim was again pressured to comply with demands tied to the Crypto extortion scheme.
Federal authorities emphasized that the use of physical intimidation marks a dangerous evolution in crypto-related crime. While digital assets are often associated with cybercrime, this Crypto extortion scheme relied heavily on real-world threats to bypass technological safeguards.
“This case shows how traditional forms of coercion are being adapted to the digital asset space,” a federal prosecutor noted, pointing to the increasing use of violence in crypto-related disputes.
A Broader Conspiracy
The Crypto extortion scheme extended beyond a single victim. Prosecutors revealed that Coberg was also involved in efforts to target another individual, identified as “R.C.,” through a fabricated drug-related arrest setup.
This aspect of the Crypto extortion scheme allegedly involved coordination with another former deputy, Christopher Cadman, who has also pleaded guilty. Authorities say the plan was designed to create leverage over the victim, further demonstrating how law enforcement resources were weaponized.
Coberg ultimately pleaded guilty in September to conspiracy to commit extortion and conspiracy against rights, formally acknowledging his role in the Crypto extortion scheme.
Meanwhile, Iza—widely regarded as the architect of the operation—remains in custody and is awaiting sentencing after pleading guilty to multiple extortion-related charges tied to the same Crypto extortion scheme.
Rising Trend of Crypto-Linked Violence
The case underscores a broader and troubling trend: the rise of violent crypto-related crimes, often referred to as “wrench attacks.” These incidents involve physical force or threats to compel victims to hand over digital assets, sidestepping encryption and cybersecurity protections.

Experts warn that the anonymity and irreversibility of cryptocurrency transactions make them particularly attractive targets in such schemes. Once funds are transferred, recovery is extremely difficult—an advantage frequently exploited in a Crypto extortion scheme.
Recent incidents highlight the global scope of the problem. In one widely reported case, a couple in western Paris was held hostage and forced to transfer nearly $980,000 in Bitcoin, illustrating how far perpetrators are willing to go in executing a Crypto extortion scheme.
A Wake-Up Call for Law Enforcement
The Coberg case has raised serious questions about internal oversight within law enforcement agencies. The involvement of sworn officers in a Crypto extortion scheme not only undermines public trust but also exposes vulnerabilities in institutional safeguards.
Legal analysts say the case could prompt stricter monitoring and accountability measures for officers with access to sensitive information and authority.
“This is a stark reminder that the integrity of law enforcement is critical, especially as financial crimes evolve,” one legal expert said, noting that insider involvement can significantly amplify the impact of a Crypto extortion scheme.
The Bottom Line
As cryptocurrency continues to reshape global finance, cases like this highlight the darker side of its rapid adoption. The Coberg-Iza operation stands as a clear example of how digital assets can be exploited through both technological and physical means.

For regulators, law enforcement, and the crypto industry alike, the lesson is clear: combating a Crypto extortion scheme requires not only better cybersecurity but also stronger institutional controls and vigilance against human exploitation.
With high-profile cases mounting, the era of purely digital crypto crime is giving way to something far more dangerous and far more personal.
