SACRAMENTO, Calif. — Anton Andreyevich Iagounov, 38, of South Lake Tahoe, was sentenced today by U.S. District Judge Daniel J. Calabretta to two years and three months in prison for four counts of impersonating a federal officer, Acting U.S. Attorney Michele Beckwith announced.
According to court documents, and evidence presented at a three-day trial in July 2024, Iagounov pretended to be a federal law enforcement agent by creating and sending counterfeit investigative documents, which he signed in the name of a fictional federal agent, seeking highly protected information from the Department of Defense.
“The defendant impersonated federal officers and tried multiple times to obtain protected information using fake court documents,” said Acting U.S. Attorney Beckwith. “Many federal agencies including NASA have devoted law enforcement officers, and we will not tolerate federal officers being illegally impersonated.”
“Mr. Iagounov’s attempt to undermine public trust in order to obtain sensitive government information posed a significant risk, potentially endangering national security and the integrity of NASA and government operations,” said Michael Graham, Acting Assistant Inspector General for Investigations. “This sentencing demonstrates the commitment of NASA OIG, the USAO, and our law enforcement partners to safeguarding Federal assets and holding accountable those who undermine justice.”
“The defendant impersonated a federal law enforcement officer and took advantage of the trust that exists between federal agencies,” said Acting Special Agent in Charge Jeremy N. Schwartz of the FBI Las Vegas Division. “All officers carry badges and credentials that are used to verify their identity. If you believe someone is impersonating an officer, you may ask their agency to confirm their official business. This sentencing demonstrates the excellent work achievable through partnerships.”
On July 5, 2022, Iagounov sent a search warrant he had created to the U.S. Capitol Police, falsely claiming it was signed by a Special Agent of NASA Office of Inspector General (NASA‑OIG) and appearing to be authorized by a U.S. District Court judge for the District of Columbia. The Capitol Police investigated the document, determined it was fake, and referred it to NASA-OIG for further investigation.
On July 11, 2022, Iagounov again pretended to be the same fictional NASA-OIG agent and sent the warrant to the U.S. District Court for the Central District of California. This time, he sent it without a judge’s signature, indicating it was for an “emergency filing” and required a judge’s signature. He sent it from an email address designed to look like it was from a United States government agency, but which Iagounov owned and had named to look like a government agency’s internet domain.
On July 18, 2022, Iagounov again sent the fake search warrant, purporting to be signed by the same fictitious NASA-OIG agent. He sent it to the U.S. Bankruptcy Court for the Middle District of Georgia, again indicating that it was for an emergency filing and needed a judge’s signature immediately.
Finally, on July 24, 2022, Iagounov faxed a letter, under the name of a real NASA-OIG supervising agent, to the U.S. District Court for the Northern District of Florida. In that letter, he claimed to be following up on the warrant, stating that an “exigent circumstance” required a judge’s signature immediately. The faxed letter included an anonymous email address for the agent that actually belonged to Iagounov. Several days earlier, on July 15, Iagounov had sent his warrant to the U.S. Bankruptcy Court for the Northern District of Florida but had received no response.
In each case, given the apparently sensitive nature of the materials Iagounov’s warrant sought, the receiving personnel for the Courts referred the matter to NASA-OIG for review and investigation.
This case was the product of an investigation by the Federal Bureau of Investigation and NASA Office of Inspector General, with assistance by the South Lake Tahoe Police Department and the Carson City Sheriff’s Office. Assistant U.S. Attorneys James Conolly and Audrey Hemesath prosecuted the case.
