The Investigative Journal’s daily review of federal enforcement actions, drawn from Justice Department press releases and court filings. All charges described below are allegations unless a plea, verdict, or sentence is noted; defendants are presumed innocent until proven guilty.
The Justice Department opened the second week of September with a wave of enforcement activity spanning transnational cybercrime, a jury conviction in a Virginia investment fraud, and the latest guilty plea and sentencings out of the department’s fraud and environmental crimes dockets. The freshest actions, announced September 8, land on top of a busy September 4 slate that included a money laundering indictment tied to what DOJ calls the largest health care fraud case it has ever prosecuted, a proposed antitrust consent decree with one of the country’s largest landlords, and voting fraud charges against five individuals in three states.
Russian web developer extradited in bank account takeover scheme
Sergei Anatolyevich Filimonov, 36, a Russian national and web developer, was arraigned Friday in the Northern District of Georgia after being extradited from the Republic of Georgia, DOJ announced September 8. A federal grand jury indicted Filimonov on November 4, 2025, on charges including conspiracy to commit bank and wire fraud, access device fraud conspiracy, and aggravated identity theft. If convicted, he faces a minimum of two years and a statutory maximum of 175 years in prison.
According to the indictment, the conspirators built spoofed domains mimicking the websites of federally insured banks and purchased sponsored search-engine links to steer customers to fraudulent login pages, then used the harvested credentials to initiate unauthorized wire transfers. Filings indicate Filimonov allegedly developed the operation’s infrastructure, including databases storing more than 5,000 stolen login credentials. The department previously seized the backend domain web3adspanels.org in connection with the scheme.
The case is notable for its international reach: DOJ credited the prosecutors general of both Georgia and Estonia, along with the FBI’s legal attaché in Tbilisi, for assistance — a reminder that Russian nationals who travel outside Russia remain within reach of U.S. process. The FBI’s Internet Crime Complaint Center has logged more than 5,100 bank account takeover complaints since January 2025, with reported losses exceeding $262 million. An indictment is an allegation only.
$1.3 billion in fraudulent Medicare billings — through a five-month-old company
A federal grand jury in Massachusetts indicted Erekle Gugava, 33, described by DOJ as an illegal alien from the country of Georgia, on one count of money laundering conspiracy. Prosecutors allege Gugava moved proceeds for the Russia-based transnational organization behind the scheme uncovered by Operation Gold Rush — the largest health care fraud case ever prosecuted by the department.
Charging documents state that Gugava purportedly owned ND Medical Solutions LLC, a Pennsylvania durable medical equipment company, for roughly five months in 2025. In that span, the company allegedly submitted at least $1.3 billion in fraudulent claims to Medicare and private insurers — billings that filings indicate relied on stolen identities of elderly and disabled Americans who later received explanation-of-benefit forms for equipment they never ordered. Insurers ultimately paid about $6.5 million, which prosecutors say Gugava routed through accounts he controlled to overseas beneficiaries. He faces up to 20 years if convicted; the charge remains an allegation.
Virginia man convicted of investor and bankruptcy fraud
A federal jury in Alexandria convicted Jihoon Park, 52, of Chantilly, Virginia, on three counts of wire fraud and two counts of bankruptcy fraud on September 8. Evidence at trial showed Park leveraged personal relationships and a former affiliation with a large national financial institution to persuade members of his community to hand over savings for promised safe, high-yield investments — then transferred more than $2.5 million to himself, buying a house and cryptocurrency.
When a victim sued, court records show, Park moved assets to his wife, concealed millions in cryptocurrency, and filed for bankruptcy claiming he held $0.34 in financial assets. Sentencing is set for December 10; Park faces up to 20 years on the wire fraud counts and five years on the bankruptcy counts.
Landlord consent decree extends DOJ’s algorithmic pricing crackdown
On the civil side, the Antitrust Division filed a proposed consent decree with Pinnacle Property Management Services LLC, one of America’s largest residential property managers, resolving claims that Pinnacle set rents using competitors’ sensitive data through RealPage’s pricing algorithms. The January 2025 complaint in the Middle District of North Carolina has now produced settlements with RealPage itself and landlords Cortland, Greystar, LivCor, and Willow Bridge.
If approved, the decree would bar Pinnacle from using pricing algorithms built on competitors’ data, prohibit sharing competitively sensitive information, and impose a court-appointed monitor if Pinnacle adopts an uncertified third-party algorithm. Pinnacle must also cooperate in the government’s case against remaining defendants. The proposed final judgment and competitive impact statement now head to a 60-day Tunney Act comment period before the court decides whether entry is in the public interest.
Five charged with illegal voting in three states
DOJ announced charges September 4 against five individuals in Pennsylvania, New Jersey, and Wisconsin related to alleged illegal voting in the 2022 or 2024 elections. In the Middle District of Pennsylvania, Marisol Guzman, 50, was charged with voting as an alien in 2024, and her husband Thomas Holtzman, 68, a U.S. citizen, with aiding fraudulent registration; Katya Rodriguez, 30, of Harrisburg, faces up to 11 years on registration and voting charges. In New Jersey, a complaint alleges Mercedes Alexandra Cardoso, who entered the U.S. from Ecuador on a tourist visa, falsely attested citizenship and voted in the June 2024 primary. In the Western District of Wisconsin, Jesus Javier Jurado Garcia, 25, was charged with voting as an alien in the November 2022 election.
Attorney General Todd Blanche called election fraud “a serious crime,” and FBI Director Kash Patel said the bureau will investigate “every credible allegation.” The department separately monitored polling sites in Manchester and Nashua for New Hampshire’s September 8 primary. All five defendants are presumed innocent; complaints and indictments contain accusations only.
Florida DME owners sentenced in $34.8M Medicare brace scheme
Kenneth Charles Kessler III, 43, of Miami, and Michael Andrew Gomez, 43, of Miramar, were sentenced to 33 and 24 months respectively after pleading guilty in May to conspiracy to commit health care fraud. Court documents show the pair ran seven durable medical equipment companies that billed Medicare $34.8 million for orthotic braces shipped to beneficiaries who neither requested nor needed them, using doctors’ orders obtained through kickbacks.
Records indicate the two shifted billing among their companies to evade Medicare payment suspensions — the same pressure-evasion pattern alleged in the Gugava indictment above. Kessler personally profited more than $1.4 million and Gomez more than $2.3 million, according to the department.
Ohio missionary pleads guilty to child exploitation in Haiti; Texas couple sentenced over smuggled pesticides
Jeriah Mast, 45, of Millersburg, Ohio, entered a guilty plea September 8 to two counts of engaging in illicit sexual conduct with minors in Haiti, where he traveled repeatedly between 2002 and 2019, including with the organization Christian Aid Ministries. Flight records obtained by investigators showed more than 30 U.S.-to-Haiti flights. Sentencing is set for December 15 in the Northern District of Ohio; the case was brought under Project Safe Childhood.
Separately, Thao Duong and Lam Mai of Garland, Texas, were sentenced September 8 for running a website selling veterinary drugs and pesticides smuggled from Mexico — products marketed largely to rooster-fighting operations. Duong received three months in prison and forfeited more than $1.5 million; Mai received probation. The EPA notes the smuggled pesticides’ active ingredient, amitraz, can reach humans through contaminated honey. The case was brought through DOJ’s Trade Fraud Task Force.
What warrants a closer look
Three threads from this cycle merit deeper TIJ reporting. First, the Operation Gold Rush laundering network: the Gugava indictment shows a company allegedly billing $1.3 billion within five months of changing hands, yet collecting only $6.5 million — a gap that raises questions about which payment-integrity screens worked, which failed, and how many other nominee owners moved money for the same Russia-based organization. Second, the RealPage endgame: with six settlements now banked and cooperation obligations stacking up, the remaining defendants in the Middle District of North Carolina face mounting pressure, and the decree’s algorithm-certification model could become the template for pricing-software regulation well beyond housing. Third, the extradition pipeline: Filimonov’s transfer from the Republic of Georgia — with Estonian and Georgian authorities assisting — suggests an increasingly effective net for Russian cyber-fraud suspects who leave home soil, a trend worth tracking against the pace of pending Interpol and mutual legal assistance activity.
Editorial note: This digest is based on public records — DOJ press releases and court filings linked above. Cases described as charged or indicted are pending, and those defendants are presumed innocent. TIJ has not received comment from counsel for defendants in the pending cases; responses will be added if provided.
