Source: United States Department of Justice Criminal Division

NASHVILLE – Thirty-eight defendants – including eight members and associates of MS-13 – have been charged on a variety of charges involving trafficking in fentanyl, methamphetamine, and cocaine, carjacking, assault on law enforcement, use of firearms during the commission of a violent crime, unlawful possession of firearms, and immigration offenses, announced Acting United States Attorney Robert E. McGuire for the Middle District of Tennessee.

These prosecutions are part of the Homeland Security Task Force (HSTF) initiative established by Executive Order 14159, Protecting the American People Against Invasion. The HSTF is a whole-of-government partnership dedicated to eliminating criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and abroad. Through historic interagency collaboration, the HSTF directs the full might of United States law enforcement towards identifying, investigating, and prosecuting the full spectrum of crimes committed by these organizations, which have long fueled violence and instability within our borders. In performing this work, the HSTF places special emphasis on investigating and prosecuting those engaged in child trafficking or other crimes involving children. The HSTF further utilizes all available tools to prosecute and remove the most violent criminal aliens from the United States.

The Nashville HSTF comprises agents and officers from Homeland Security Investigations (HSI), the Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF), the Federal Bureau of Investigation (FBI), Internal Revenue Service Criminal Investigations (IRS-CI), U.S. Postal Inspection Service (USPIS), United States Marshals Service (USMS), United States Secret Service (USSS), Drug Enforcement Administration (DEA), and other federal agencies, working in collaboration with our state and local partners, with the prosecutions being led by the United States Attorney’s Office for the Middle District of Tennessee.

“These efforts illustrate law enforcement’s commitment to stop gang violence, combat the scourge of fentanyl overdoses here in Middle Tennessee, and hold offenders accountable for the havoc they have wreaked on our community,” said Acting U.S. Attorney McGuire. “Working together as part of the Homeland Security Task Force, these agencies have made our communities throughout Middle Tennessee safer and stronger.”

In United States vs. Rodriguez and United States v. Mendoza, Victor Alfonso Paez Rodriguez and Jesus Mendoza Viera, both of whom are illegally present in the United States, are alleged to have trafficked large quantities of fentanyl from Mexico into middle Tennessee. HSI was the lead investigative agency with assistance from the Metropolitan Nashville Police Department (MNPD).

In United States v. Copeland, Trenell Copeland, Tabria Bowens, Cassandra Lawson, Alicia Barman, and Ashanti Williams are charged with offenses related to the trafficking of fentanyl, methamphetamine, and marijuana into the Trousdale County Correctional Facility where Trenell Copeland was serving a state sentence. The lead investigative agency was the FBI with assistance from the Tennessee Department of Corrections Office of Investigations and Conduct (TDOC-OIC).

In United States v. Bangeas, Debyi Bangeas – an MS-13 member who is illegally present in the United States– was charged with carjacking, use of a firearm during that carjacking, and unlawful possession of a firearm. The lead federal agencies were ATF and HSI in collaboration with MNPD.

In United States v. Contreras Arita, two MS-13 members, Kevin Jasir Contreras Arita, Jose Pena, and MS-13 associate David Dubon-Enamarado, were charged with drug trafficking, assault on a federal law enforcement officer with a deadly weapon, and illegal re-entry into the United States. The lead federal agencies were HSI and ATF in collaboration with MNPD.

In United States v. Leonel Vargas, MS-13 member Leonel Vargas, who is illegally present in the United States, was charged with drug trafficking cocaine and marijuana, possession of a firearm in furtherance of drug-trafficking, and being an illegal alien unlawfully in possession of a firearm. The lead federal agencies were ATF and HSI in collaboration with MNPD.

In United States v. Anthony Vargas, MS-13 associate Anthony Vargas, who is illegally present in the United States, was charged with being an illegal alien unlawfully in possession of a firearm. According to court documents, Vargas was caught with a stolen firearm which has ballistic associations to the homicide of a fourteen-year-old girl. The lead federal agencies were ATF and HSI in collaboration with MNPD.

In United States v. Sandoval, thirteen defendants, including one MS-13 member and one MS-13 associate, were charged as part of a methamphetamine and cocaine distribution conspiracy resulting from a months’-long investigation. The lead agencies were the Department of the Army Criminal Investigation Division (Army CID) and DEA with assistance from ATF, HSI, FBI, USMS, USSS, the Tennessee Bureau of Investigation (TBI), MNPD, and the Tennessee Highway Patrol (THP).

In United States v. Toliver, twelve defendants were charged with trafficking in fentanyl sourced from outside the United States as well as multiple federal firearms charges. Crossville has experienced a spike in the number of overdose deaths linked to fentanyl. Some of those overdoses are alleged to be connected to the trafficking activities of these defendants. The lead agencies were the FBI, TBI, and the Cumberland County Sheriff’s Office with assistance from HSI, the Putnam County Sheriff’s Office and THP.

These cases are being prosecuted by Assistant U.S. Attorneys Katy Risinger, Joshua Kurtzman and Emily Petro. AUSA Risinger is the Lead HSTF Attorney for the Nashville Homeland Security Task Force.

An indictment or a complaint is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.

United States Attorney Announces Criminal Complaint in Cordova Robbery and Shooting Incident

Source: United States Department of Justice Criminal Division

Memphis, TN – United States Attorney D. Michael Dunavant announced the federal criminal complaint of Marquis Davis, 18, charging him with business robbery and the discharge of a firearm during and in relation to a crime of violence.   

On the early afternoon of October 31, 2025, Marquis Davis entered the Exotic Smoke Shop in the 1700 block of Germantown Parkway in Cordova, Tennessee. Shortly thereafter, Davis pulled out a firearm with an extended magazine and demanded money from the employee. The employee complied and opened the cash register; and Davis took approximately $400 from the register, before shooting her in the abdomen.  Davis then fled the building.

After Davis fled the building, he encountered four federal agents who had just finished eating at a nearby restaurant.  The agents saw Davis with a firearm and based on Davis’s actions at that point, federal agents fired their duty weapons, striking Davis.  Federal agents and a responding Memphis Police Department officer took Davis into custody. They located a black firearm with an extended magazine next to Davis and approximately $370 in U.S. currency in his clothing.

A bystander and a retired paramedic located the store clerk, who was suffering from a gunshot wound.  They provided aid until medical personnel arrived and transported the victim to the hospital where she underwent emergency surgery for the gunshot wound.

Davis was also rushed to the hospital and underwent surgery.  He survived and remains in state custody. Davis’s current federal charges carry a mandatory minimum sentence of 10 years and up to life imprisonment, and supplemental federal charges may be added after completion of the ongoing investigation. Davis has also been charged in state court with the felony offenses of Attempted First Degree Murder, Aggravated Robbery, and Employment of a Firearm During the Commission of a Dangerous Felony.

This case is set before District Judge Thomas L. Parker of the Western District of Tennessee.  

Assistant United States Attorneys Jermal Blanchard and Greg Wagner are prosecuting this case on behalf of the United States.

The charges and allegations contained in the criminal complaint are merely accusations of criminal conduct, not evidence.  The defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt and convicted through due process of law.

Former credit union manager sentenced to prison for decade-plus embezzlement scheme

Source: United States Department of Justice Criminal Division

KANSAS CITY, KAN. – A federal judge sentenced a former Kansas credit union manager to 63 months in prison for stealing more than $750,000 from her long-time employer and substantially jeopardizing the safety and soundness of the financial institution.

According to court documents, Rita Hartman, 71, of Atchison pleaded guilty to one count of false entries in federal credit union records.

For 30 years, Hartman was the manager of Muddy River Credit Union (formerly Atchison Casting Credit Union and Bradken Federal Credit Union), which served the employees of a foundry located in Atchison, Kansas. Hartman’s position gave her control over all aspects of Muddy River’s finances. Between 2007 and 2021, she abused the trust that Muddy River granted her to steal approximately $346,00 in customer cash deposits. Hartman also fraudulently credited approximately $430,000 in deposits and loan payments to her or her relatives’ accounts when no payments or deposits had been made. Hartman concealed her conduct by altering ledgers and records and by falsifying information submitted to Muddy River’s regulators.  She obstructed efforts to uncover her fraud by submitting fraudulent documents to regulators and delaying a mandated audit.  

The defendant’s embezzlement wiped out Muddy River’s capital and rendered it insolvent, ultimately forcing a merger into another credit union to continue operations. 

In 2013, the then-Governor of the State of Kansas appointed Hartman to the Kansas Credit Union Council, which advises the Kansas Department of Credit Unions on issues and needs of credit unions. Hartman is also a former mayor and city commissioner in Atchison. A federal judge ordered that during her imprisonment, all of Hartman’s state pension payments be directed towards the $778,361 in restitution she was ordered to pay as part of her sentence.

“For decades, Rita Hartman was a prominent, well-respected figure in Atchison, Kansas,” said U.S. Attorney Ryan A. Kriegshauser. “Instead of living up to the high regard that people in the community had for her, she exploited their trust and used it to perpetuate her embezzlement scheme and line her pockets with stolen funds.” 

“The defendant was entrusted with the fiscal responsibility of the credit union’s members. In using the money for her personal benefit, the defendant’s actions were a betrayal of that trust,” said Special Agent in Charge Stephen A. Cyrus of the FBI Kansas City Field Office. “This sentencing demonstrates the FBI’s longstanding commitment to working financial fraud investigations and to hold individuals accountable for their actions.”

The Federal Bureau of Investigation (FBI) investigated the case.

Assistant U.S. Attorneys Ryan J. Huschka and Michelle McFarlane prosecuted the case.

Bartow County felon who shot at police sentenced to decade in federal prison

Source: United States Department of Justice Criminal Division

ROME, Ga. – Shane Jacquces Barfield, a multi-convicted felon and domestic abuser, has been sentenced to federal prison for unlawfully possessing a firearm that he shot at local law enforcement.

“Dangerous felons like Barfield forfeit the right to bear arms,” said U.S. Attorney Theodore S. Hertzberg. “Barfield broke the law when he possessed and discharged a stolen gun, endangering the safety of police officers and bystanders alike. Thanks to the brave, on-scene efforts of the Cartersville Police Department and subsequent collaboration with the FBI, Barfield will now serve a significant sentence in federal prison without the possibility of parole.”

“Shane Barfield knew he was not supposed to be in possession of a gun, much less fire one, but he violated the law,” said FBI Atlanta Special Agent in Charge Paul Brown. “His actions could have been deadly. Thankfully, no law enforcement nor citizens were hurt.”

“Not only was Barfield a threat to our officers that day, but a violent, convicted felon with an illegal firearm is a continual threat to our community,” said Cartersville Police Chief Frank McCann.  “A threat that the Cartersville Police Department will not tolerate. We appreciate the FBI for their assistance, and the U.S. Attorney’s Office for their steadfast commitment to supporting the Cartersville Police Department in its public safety mission.”

According to U.S. Attorney Hertzberg, the charges, and other information presented in court: On September 17, 2023, Shane Barfield was driving through Cartersville, Georgia, with a stolen gun and methamphetamine in his vehicle. Barfield lost control of his vehicle, skidded through an intersection, and crashed into the side of the road. Bystanders called 911 to report the accident and told dispatchers that Barfield had walked away from his vehicle with a gun in his hand. 

Barfield returned to his vehicle with the gun, and the Cartersville Police Department (CPD) responded shortly thereafter.  Despite clear instructions to toss the firearm and exit his car, Barfield ignored law enforcement. As a CPD officer crossed in front of his vehicle, Barfield fired a shot. Three officers returned fire, striking Barfield’s vehicle multiple times.  Officers then arrested Barfield and seized a spent 9mm casing, a stolen pistol, and methamphetamine from his vehicle. A federal investigation requested by CPD determined that the spent casing had been expelled from the stolen firearm.   

On November 4, 2025, U.S. District Judge William M. Ray, II sentenced Shane Jacquces Barfield, 39, of Cartersville, Georgia, to 10 years in prison followed by three years of supervised release. Barfield was convicted of possession of a firearm by a convicted felon and possession of a firearm by a person convicted of a misdemeanor crime of domestic violence on May 15, 2025, after he pleaded guilty.

This case was investigated by the Federal Bureau of Investigation and the Cartersville Police Department.

Assistant U.S. Attorney Katie Terry prosecuted the case.

Topeka Man Sentenced to 25 Years for Artificial Intelligence Related Child Exploitation Offenses

Source: United States Department of Justice Criminal Division

TOPEKA, KAN. – A Kansas man was sentenced to 25 years in prison for five counts of transportation of child pornography and one count of possession of child pornography.

According to court documents, Jeremy Weber, 47, of Topeka uploaded photographs of women and children he knew into a publicly available Artificial Intelligence platform. He then utilized AI to manipulate and merge their images into hundreds of depictions of child sexual abuse material (or CSAM).  Weber also uploaded previously trafficked images of CSAM to the same platform. Weber morphed the original CSAM image with the face of the adult or minor female, creating a new image of CSAM. 

The investigation identified approximately 32 women whose images were used to produce the new CSAM.  In addition, Weber utilized the same AI program to produce adult pornographic images of 50-60 women without their consent.  

The investigation into Weber began after an IT professional observed criminal activity on Weber’s computer and reported it to local law enforcement.  A subsequent search warrant led to a search of Weber’s residence and the discovery of an encrypted hard drive containing a folder titled “AI Swap.” In the folder was a large number of files organized into folders named after women. Each of the named folders contained anywhere from a handful to hundreds of newly manufactured sexually explicit images of each individual.

“While it is still an emerging technology, I believe there can be many wonderful and beneficial aspects of artificial intelligence, but there is also a dark side. Unfortunately, child predators are using AI for twisted and perverse activities,” said U.S. Attorney Ryan A. Kriegshauser. “The fact that Jeremy Weber was able to create realistic looking images of child pornography using the faces of children and adults should remind us that we are all vulnerable to this type of violation. Although the images were ‘fake’, the harm he inflicted on the victims and the consequences were very real.” 

“The FBI is grateful for the work of the U.S. Attorney’s Office and our law enforcement partners, including the Topeka Police Department for their work in this case,” said Special Agent in Charge Stephen A. Cyrus of the FBI Kansas City Field Office. “The sentencing reflects the severity of conduct the defendant has pled to and should send a message to anyone conducting this type of behavior: the FBI will not flinch to seek justice.”  

The Federal Bureau of Investigation (FBI) and the Topeka Police Department investigated the case.

U.S. Arrests Five Fugitives Wanted by Germany for Massive Fraud Scheme

Source: United States Department of Justice Criminal Division

The United States arrested five international fugitives at the request of the Federal Republic of Germany, which has charged the individuals for their roles in a network involving German payment service processors that defrauded thousands of victims of more than €300 million and created a shadow financial system in Germany. Pursuant to its treaty obligations, the United States located and arrested the fugitives in the Central District of California for ultimate extradition to Germany.

Four U.S. citizens residing in California — Medhat Mourid, of Woodland Hills, Andrew Garroni, of Los Angeles, Guy Mizrachi, of Agoura Hills, Ardeshir Akhavan, of Irvine — and Canadian National Tunde Benak, of Irvine, were arrested by the U.S. Marshals Service and made their initial appearances in federal court today.

Acting Assistant Attorney General Matthew Galeotti of the Justice Department’s Criminal Division, First Assistant U.S. Attorney Bill Essayli of the Central District of California, and Director Gadyaces S. Serralta of the U.S. Marshals Service made the announcement.

Germany alleges that the fugitives defrauded victims in violation of German law by creating millions of recurring, fraudulent debit or credit card charges from fictitious merchants. According to German authorities, the defendants orchestrated a scheme in which they deliberately kept monthly charges on credit cards to below €50, to avoid suspicion among victims about the nature of the charges.  These charges were linked to fictitious companies using fictitious websites that were only accessible via direct links or URL’s.  

The operators of the network then colluded with German payment service processors – including their executives and compliance officers – to process these payments.  Former employees and executives of German payment processors are among those arrested yesterday. German authorities allege that this complex scheme resulted in the creation of a shadow financial system in Germany.

In the United States, the Department of Justice’s Office of International Affairs (OIA), the U.S. government’s central authority in criminal matters, worked closely with German officials and the U.S. Attorney’s Office for the Central District of California to provide legal guidance and coordinate the successful arrest of the U.S.-based defendants. OIA participated in coordination meetings related to the takedown and worked directly with the German prosecutor to ensure Germany met U.S. legal requirements to arrest these fugitives with a view toward extradition.

The U.S. Marshals Service for the Central District of California arrested the fugitives in the United States contemporaneously with arrests and/or searches in Germany, Italy, Luxembourg, Spain, Cyprus, the Netherlands, the United Kingdom, Canada and Singapore.

Fiber laser expert convicted by a federal jury of economic espionage and theft of trade secrets

Source: United States Department of Justice Criminal Division

ROCHESTER, N.Y. – A federal jury has convicted Ji Wang, 63, of Painted Post, NY, of two counts of economic espionage, one count of theft of trade secrets, one count of attempted economic espionage, and one count of attempted theft of trade secrets.  Assistant Attorney General for National Security John A. Eisenberg, together with U.S. Attorney Michael DiGiacomo for the Western District of New York, announced the verdict.

“This conviction demonstrates the importance of protecting trade secrets developed in the United States, especially those with military applications,” stated U.S. Attorney DiGiacomo. “My office will continue pursue and prosecute those that steal such information.”

“Yesterday, a federal jury found Wang guilty of stealing sensitive defense research from his employer and attempting to use it to pursue personal profit at the expense our national security. We are committed to combating economic espionage and holding accountable those who disregard our export-control laws and the security of U.S. technology,” said Assistant Attorney General for National Security John A. Eisenberg. “This verdict reaffirms that such betrayals of trust will not go unpunished.”

“This conviction underscores the FBI’s dedication to exposing those who steal U.S. trade secrets for foreign benefit,” said Philip Tejera, Special Agent-in-Charge of the FBI’s Buffalo Field Office. “Any theft of valuable intellectual property is a threat to American businesses. When stolen trade secrets stand to benefit a foreign economic rival; it threatens our national security. The FBI remains committed to investigating individuals who trade American security for their own selfish greed.”

“The Bureau of Industry and Security remains committed to working alongside our law enforcement and industry partners to prevent the unlawful transfer of sensitive technologies,” said Special Agent-in-Charge Jonathan Carson.

Wang was born in China and immigrated to the United States in 1998 to work for Corning Incorporated.  Between 2002 and 2007, Wang was assigned to work on a joint research and development project funded by the Defense Advanced Research Projects Agency (“DARPA”) and Corning.  The goal of the 5-year, $11.4 million project was to develop optical fibers for high-powered lasers with military and commercial applications.  DARPA and Corning aimed to increase the power of fiber lasers by more than a factor of 1000.  DARPA sought to develop this technology to create laser weapons capable of shooting down drones and missiles.

On or about July 1, 2016, Wang stole hundreds of files that contained non-public data generated during the DARPA project, including trade-secret manufacturing technology that would have enabled him to fabricate all manner of specialty optical fibers, including for fiber lasers.

Ten days before Wang stole the trade secret files, he had applied for China’s Thousand Talents Plan Award.  The Thousand Talents Plan Award was an initiative by the Chinese government aimed at people who were born in China and immigrated to the United States, to study or work in science and technology fields.  The Thousand Talents Plan Award incentivized these people to return to China by promising millions of dollars of investment to award recipients who returned to China.  Two months after Wang stole the trade secret files, he was selected to receive a Thousand Talents Plan Award.

Wang was negotiating with Chinese government entities to start a specialty fiber business in China from at least 2014 through 2017.  Wang was negotiating to receive tens of millions of dollars in investment from Chinese government entities, who would have been shareholders in his new venture.  Wang’s business plans showed that he was planning to use the stolen trade-secret files to start this business in China. Wang’s business plans also touted the military applications of the technology.  In one such business plan, which Wang submitted to a Chinese government entity, he advertised that specialty fibers “can also be installed on military vehicles,” including “tanks.”  Wang claimed that such use of the technology on military vehicles could “be key to deciding victory or defeat.” Ultimately, law enforcement disrupted Wang’s efforts before he was able to start a new business and exploit the technology he stole.

The verdict is the result of an investigation by Special Agents of the Federal Bureau of Investigation, acting under the direction of Special Agent In-Charge Philip Tejera, and Special Agents of the Department of Commerce, Office of Export Enforcement, New York Field Office acting under the direction of Special Agent-in-Charge Jonathan Carson.  Additional assistance was provided by Homeland Security Investigations in Detroit, Michigan.  The case was prosecuted by Assistant United States Attorney Meghan K. McGuire of the Western District of New York and Trial Attorneys Nicholas Hunter and Brendan Geary of the Counterintelligence and Export Control Section of the National Security Division.

Economic espionage carries a maximum penalty of 15 years in prison and theft of trade secrets carries a maximum sentence of 10 years in prison.  Sentencing is scheduled for April 15, 2026, at 2:00 p.m. before U.S. District Judge Frank P. Geraci, Jr., who presided over the trial.

Three Chinese National scholars from University of Michigan laboratory charged for conspiring to smuggle biological materials into the U.S.

Source: United States Department of Justice Criminal Division

DETROIT, Mich – Three research scholars from the People’s Republic of China (PRC) were charged today in a criminal complaint with conspiracy to smuggle biological materials into the United States and for making false statements to U.S. Customs and Border Protection Officers, announced United States Attorney Jerome F. Gorgon, Jr. These are the latest charges in a long string of cases stemming from University of Michigan (UM) international research activities.

“Allegedly attempting to smuggle biological materials under the guise of ‘research’ is a serious crime that threatens America’s national and agricultural security,” said Attorney General Pamela Bondi. “We will remain vigilant to threats like these from foreign nationals who would take advantage of America’s generosity to advance a malicious agenda.”

“At some point, pattern becomes practice. And, apparently, these three men are part of a long and alarming pattern of criminal activities committed by Chinese Nationals under the cover of the University of Michigan. This is a threat to our collective security. We are thankful for the vigilance of our elite federal partners—ICE HSI, FBI, and CBP—as a counterweight against this threat,” said United States Attorney Gorgon.

Charged were Xu Bai, 28, Fengfan Zhang, 27 and Zhiyong Zhang, 30. Bai and F. Zhang were charged with conspiracy to smuggle biological materials into the United States and Z. Zhang was charged with making false statements to federal agents.  All three men were research scholars holding J-1 visas who were conducting research at the UM laboratory of Xianzhong Xu, commonly referred to as the Shawn Xu laboratory.

According to the criminal complaint, in 2024 and 2025, Bai and F. Zhang were the recipients of multiple shipments containing concealed biological materials related to round worms which had been sent from the PRC to the United States by Chengxuan Han, a citizen of the PRC. Han was pursuing a Ph.D. from the College of Life Science and Technology in the Huazhong University of Science and Technology (HUST) in Wuhan, PRC and in June 2025, traveled to the United States to work in the laboratory at UM.  Han recently pleaded no contest to three counts of smuggling and one count of false statements, was sentenced and then removed from the United States.

After Han’s arrest and removal from the United States, UM initiated an internal investigation into the Shawn Xu laboratory. All three defendants refused to attend a mandatory meeting or participate in the investigation and so were terminated. This termination made them eligible for removal by the Department of Homeland Security.

The defendants purchased airline tickets to depart the United States from Detroit Metropolitan Airport (DTW) to the PRC on October 20, 2025. On October 10, 2025, federal agents attempted to locate the defendants at their home and elsewhere but were unsuccessful. That same day, the defendants rebooked their flights for October 15, 2025. They also booked flights to the PRC departing from John F. Kennedy International Airport for 2:00 a.m. on October 16, 2025. The defendants did not cancel or show for their DTW flight on October 15, 2025. Defendants instead traveled to New York and attempted to board the early morning JFK flight to the PRC on October 16. During an inspection by CBP, Z. Zhang made false statements about Han. Bai and F. Zhang told CBP officers they had received packages from Han including after her arrest or removal from the United States.

“This case underscores the vital importance of safeguarding the American people and addressing vulnerabilities within foreign student and exchange visitor programs,” stated acting ICE Director Todd M. Lyons. “Educational institutions must enhance their admissions procedures to prevent exploitation, which can pose risks to national security, as demonstrated in this instance. I commend the ICE HSI agents and officers who work tirelessly to protect our nation and uphold the rule of law every day.”

“These charges show the FBI and our partners will aggressively investigate and hold accountable those who violate our laws, and that academic research cannot excuse illegal activity,” said FBI Director Kash Patel. “The Chinese nationals charged today allegedly were involved in smuggling biological materials into the U.S. on several occasions.
