Ronald Dale Koontz, 69, of Hendersonville, Tennessee, Demitrios George Macropoulos, 38, of Buckeye, Arizona, Randy L. Nowland, 67, of Waltonville, Illinois, and Cory Taylor Humphrey, 37, of Prospect, Kentucky, have been charged with multiple crimes related to an underground fire that occurred in the MC#1 Mine in Franklin County, Illinois, in August 2021.
The indictment returned Tuesday charges Koontz, Macropoulos, Nowland, and Humphrey with conspiring to defraud the U.S. Mine Safety and Health Administration (MSHA) by concealing the fire and other hazards at the mine and taking steps to interfere with MSHA’s investigation of the fire and administration of safety-related orders in the aftermath of the fire. The Indictment charges the defendants with keeping miners underground and continuing to mine coal for all or portions of three shifts while unsuccessfully fighting a fire. The defendants are charged with failing to evacuate the mine and notify MSHA as required by mandatory safety standards under the Federal Mine Safety and Health Act (the Mine Act). Nowland and Humphrey are also charged under the Mine Act with falsification of records required to document mine hazards. Koontz and Macropoulos are charged with obstruction of an MSHA proceeding for entering the mine in violation of an MSHA safety order withdrawing miners from the mine. Koontz is further charged with obstruction for directing another supervisor to delete a record reflecting a telephone call he made. A fifth conspirator and former mine manager, Brandon Timothy Parsons, pleaded guilty to conspiracy to defraud MSHA on Aug. 28, 2025 in a related criminal proceeding filed in August 2025.
“As Congress has long recognized, a strong, productive coal industry depends on miners who feel safe and trust that their leaders are not putting them at unnecessary risk,” said Principal Deputy Assistant Attorney General Adam Gustafson of the Energy and Natural Resources Division. “Supporting MSHA’s work to protect coal miners is an important part of ENRD’s mission.”
“When people in positions of authority conceal deadly conditions and then cover up their actions, they put lives at risk and prevent federal authorities from doing the job the law requires them to do. That kind of obstruction is unacceptable,” said U.S. Attorney Steven D. Weinhoeft for the Southern District of Illinois. “These charges hold accountable those who chose to protect the company’s financial interests over the safety of the people they are obligated to protect.”
As alleged in the Indictment, in August 2021, Koontz was the general manager of a company that provided oversight and services to the corporate operator of the MC#1 Mine. Macropoulos was the mine superintendent of the MC#1 Mine and Nowland and Humphrey were shift mine managers. On or about the afternoon of Aug. 13, 2021, an underground fire was ignited while mine personnel used cutting torches to cut collapsed steel beams in the mine. According to the Indictment, when the fire could not be extinguished within 10 minutes, rather than implementing the approved Mine Emergency Evacuation and Firefighting Plan, the defendants, and their co-conspirator Parsons, allegedly agreed that they would not evacuate miners or notify MSHA. Instead, the defendants are alleged to have directed coal mining to continue during ad hoc firefighting efforts through the morning of Aug. 14. Nowland and Humphrey are charged with signing records of required mine examinations, falsely certifying that no hazardous conditions existed in the mine.
On August 14th, Parsons tried to conceal the existence of the fire from those not already aware of it by evacuating the mine of hourly employees on the false pretense that a belt used to carry coal from underground to the surface was broken. Members of the conspiracy, including Koontz, Macropoulos, and Parsons, are alleged to have then gone underground to continue their attempts to fight the fire.
Later that morning, MSHA received an anonymous tip about the fire and, by that afternoon, ordered that the mine be evacuated after inspectors confirmed the existence of the fire. Despite the evacuation order, over the next several days, it is alleged that conspirators re-entered the mine in violation of MSHA’s order on two occasions to assess the fire and manipulate the conditions underground to fool underground gas detectors so that MSHA would allow mining to resume. When MSHA began collecting portable gas detectors worn by miners during the fire as part of its investigation, a member of the conspiracy allegedly encouraged another co-conspirator to get rid of the portable gas detector he had worn. That co-conspirator concealed his portable gas detector away from the mine.
If convicted, the defendants each face possible incarceration. If found guilty, a federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

Today, a federal jury convicted a dual U.S.-Ghanaian citizen for his role in a scheme to bribe Ghanaian officials in connection with the development and financing of a multi-million-dollar power plant in Ghana.
“We live in a global economy that American companies must be able to compete in fairly,” said Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division. “This defendant corrupted that fair competition. He abused his position at a world-renowned American investment bank by helping bribe Ghanaian officials, so he and his co-conspirators, including senior executives at a Turkish company, could make money. Today’s conviction makes clear that criminals who undermine our country’s interests by corrupting foreign governments and cutting off fair competition will face the full force of the Department of Justice.”
“Today’s verdict marks another significant victory in this Office’s longstanding commitment to rooting out corruption,” said U.S. Attorney Joseph Nocella Jr. for the Eastern District of New York. “The defendant abused his access to high-level foreign government officials and his platform as an investment banker at a prestigious American firm to greedily line his own pockets.”
“Engaging in bribery damages the reputation of businesses and destroys fair competitions,” said Acting Assistant Director Matthew B. Floyd of FBI’s Criminal Division. “Berko intentionally lied to his company to continue his scheme. The FBI will not tolerate dishonesty or corruption from anyone who wishes to disturb the business market.”
According to court documents and evidence presented at trial, Asante Kwako Berko, 52, conspired to pay more than $1 million in bribes to multiple Ghanaian government officials in connection with the development and financing of a power plant estimated to generate hundreds of millions of dollars in revenue.
Beginning in December 2014, Berko, a former Executive Director in the Investment Banking Division at Goldman Sachs, was responsible for securing and managing a deal between Aksa Enerji, a Turkish energy company and client of Goldman Sachs, and the Republic of Ghana, for the construction and financing of a power plant in Ghana amidst a national energy crisis in the country.
During the scheme, Berko and his co-conspirators paid and conspired to pay bribes to individuals at numerous levels of the Ghanaian government to ensure that the Turkish Energy company won its bid to build and operate the power plant. In April 2015, Berko and the conspirators discussed paying $1 million to the Minister of Power who was responsible for securing key approvals enabling the project to progress.
Bribes were also paid to five Ghanaian officials during an all-expenses-paid trip to Turkey to view equipment for the power plant, during which the officials each received $5,000. After the power plant deal was ratified by the Ghanaian parliament in July 2015, Berko and his co-conspirators emailed about their bribe payments at length. The evidence further detailed tens of thousands of dollars in bribes that Berko had personally paid and for which he was still owed.
To conceal the scheme from Goldman Sachs and others, Berko lied to Goldman’s compliance team that was responsible for vetting the deal and he used his personal, non-official-business email account when talking about the bribes. Berko and his co-conspirators also concealed and laundered the bribe payments using shell companies, sham invoices, nominee account holders and cash withdrawals. Payments in furtherance of the bribery scheme were laundered through U.S. and foreign bank accounts, including several in Berko’s name. Goldman ultimately withdrew from the deal due to corruption concerns.
The jury convicted Berko of conspiracy to violate the Foreign Corrupt Practices Act (FCPA), violating the FCPA, and money laundering conspiracy. A sentencing date has not been set. He faces a maximum penalty of 30 years in prison. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.
The FBI is investigating the case. The Justice Department’s Office of International Affairs and the FBI’s Law Enforcement Attaché in Accra worked with the International Cooperation Unit of the Office of the Attorney-General of Ghana, and Ghana’s Office of the Special Prosecutor, to provide significant assistance to this prosecution.

A South Carolina manager of a bovine artificial insemination firm pleaded guilty today to rigging bids for the purchase of cattle used either for the direct production of semen or for the development of animals for future semen production.
According to court documents filed in the U.S. District Court in Columbus, Ohio, Herbert D. Lutz, 56, of Chester, SC pleaded guilty to conspiring to rig bids between at least as early as October 2018 and at least as late as May 2024. In advance of cattle auctions, Lutz and his co-conspirators agreed which company would win the bid. During the sales, the agreed-upon losing firm would either not bid or would submit an intentionally-losing bid before bowing out to permit the agreed-upon winner to prevail. Through the efforts of Lutz and his co-conspirators, Lutz’s employer was able to acquire cattle worth over $1.6 million through rigged sales.
Bovine artificial insemination firms produce, market, and sell bovine semen for artificial insemination, research, and genomics. As part of their business, such firms purchase cattle from third parties, including through competitive public auctions, either for the direct production of semen for sale or to develop animals for future production.
“The tireless work of our Nation’s ranchers and farmers is essential to everyday affordability for all Americans,” said Associate Attorney General Stanley E. Woodward Jr. “This Department of Justice will never stand for collusion that cheats hardworking, honest producers and raises prices for American families putting food on the table. Collusion and bid rigging is criminal, and we will prosecute it to the fullest extent of the law.”
“Collusion in the agricultural industry ultimately leads to higher food prices for consumers,” said Acting Deputy Assistant Attorney General Daniel Glad of the Justice Department’s Antitrust Division. “The Antitrust Division is dedicated to stamping out such collusion and prosecuting those responsible, thereby ensuring that our food supply remains affordable and plentiful for all Americans.”
“Bid rigging harms not only consumers, but also hard-working ranchers and farmers who are cheated out of competitive prices for their cattle,” said Acting Special Agent in Charge Salvador Gonzalez of the Agriculture Department’s Office of Inspector General Midwest Field Office. “We will continue to work alongside our partners at the Antitrust Division to safeguard the rural way of life from corporate greed.”
Lutz is the first defendant to be charged and to plead guilty in the ongoing investigation into bid rigging in the bovine artificial insemination industry. Lutz pleaded guilty to conspiracy to rig bids in violation of Section 1 of the Sherman Act and faces a maximum penalty of 10 years in prison and a $1 million criminal fine. The maximum penalty for corporations is a $100 million criminal fine. The fine may be increased to twice the gain derived from the crime or twice the loss suffered by the victims of the crime if either amount is greater than the statutory maximum fine. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.
The Antitrust Division’s Chicago Office is prosecuting the case, which was investigated with the assistance of the Department of Agriculture Office of Inspector General.
