US Sheriff Involved in Crypto Extortion Case: Impersonated Law Enforcement Authority to Extort Rival, Sentenced to 63 Months

Gate News reports that on March 16, the U.S. Department of Justice disclosed that former Los Angeles County Deputy Sheriff Michael David Koberger was sentenced to 63 months in federal prison for involvement in cryptocurrency-related extortion and false law enforcement activities. The case involves abuse of police authority, extorting competitors, and fabricating arrest procedures, sparking widespread discussion at the intersection of the crypto industry and law enforcement.

According to prosecutors, Koberger conspired with entrepreneur Adam Iza, who claims to be the “godfather” of cryptocurrency, to intimidate and pressure targets using law enforcement credentials, carrying out extortion against those with business disputes with Iza. Koberger pleaded guilty in September 2025, admitting to using his law enforcement status to support illegal activities.

Investigations revealed that Iza had long employed off-duty law enforcement officers as bodyguards and consultants, paying high fees to help him obtain information on competitors and interfere in business conflicts. The indictment states that Koberger received at least $20,000 per month while still serving in the law enforcement system.

A key allegation in the case involves a confrontation in October 2021. A victim was taken to a private residence in Los Angeles, where Iza displayed a weapon to pressure the victim, while Koberger, in active duty, participated in questioning. Ultimately, the victim was forced to transfer approximately $127,000 to an account controlled by Iza.

Additionally, prosecutors uncovered a carefully planned “fake arrest” operation. Iza and Koberger lured the victim from Florida to Los Angeles, staged a traffic stop at a prearranged location, and another law enforcement officer arrested the victim on suspicion of drug possession. The two then watched and filmed the scene to intimidate and mock afterward.

Adam Iza was previously arrested in September 2024 and faces multiple charges including conspiracy, telecommunications fraud, and tax evasion. These cases involve tens of millions of dollars, including about $16 million in crypto assets, and are related to other criminal cases such as attempted home invasion.

Prosecutors pointed out that this case highlights the risks of individual law enforcement officers abusing power to participate in crypto-related crimes and reflects how some gray capital leverages law enforcement resources to expand illegal influence. Iza has pleaded guilty and is awaiting final sentencing in federal court; the case is still under further investigation.
