Federal authorities have disclosed new information regarding an alleged illegal gambling operation in Northern Indiana, highlighting the involvement of credit betting, local businesses, and intimidation techniques.
The investigation, which has led to the indictment of 22 individuals, reveals a network that utilized offshore betting platforms, credit lines, and legitimate businesses as fronts for their activities. U.S. Attorney Adam Mildred announced that a federal grand jury has charged the defendants with running a conspiracy that employed extortionate methods to recover gambling debts and launder money.
According to federal officials, the illegal activities took place from 2021 until April 2026, describing the operation as a well-organized group of bookmakers, enforcers, and financial intermediaries functioning both online and through local enterprises.
FBI Special Agent Timothy O’Malley emphasized the severity of the situation during a press conference, stating, “This was not a case of harmless or casual gambling. It was part of a broader pattern of criminal behavior that included coercion, intimidation, and financial exploitation.” He further noted that such operations instill fear in communities and have a widespread impact beyond those directly involved.
The press conference also detailed enforcement actions related to the case, which included arrests in multiple states such as California, Florida, Illinois, New York, and Puerto Rico. Authorities executed seven search warrants across Northern Indiana in an operation named “Operation Porterhouse Parlay,” involving over 150 law enforcement personnel.
Officials described this case as the culmination of a multi-year investigation involving various agencies, including the FBI, IRS, and Indiana Gaming Commission. Mildred confirmed that the investigation is still active, stating, “The law enforcement team will pursue any additional crimes uncovered by the evidence and any other individuals who may have participated.” Authorities are also urging victims and witnesses to come forward.
The indictment provides insights into the operation's structure, led by James Gerodemos, known as “Jimmy the Greek,” and Dean Gialamas, referred to as “Dean Gem.” Gerodemos previously served six months in prison in 2015 for handling explosive materials without a license.
The gambling ring operated offshore betting sites such as abcwagering.ag and gardencitybets.com, where accounts were managed through bookies instead of direct user registrations. Bettors were granted lines of credit that allowed them to place bets without initial deposits.
Additionally, the indictment mentions a high-stakes Super Bowl “line pool,” with entry fees ranging from $500 to $25,000 and gross proceeds estimated between $700,000 and $900,000 per game. Federal authorities have not yet disclosed the total revenue linked to the entire operation.
The network of bookmakers was responsible for collecting losses and distributing winnings through various methods, including cash, checks, wire transfers, and apps like Zelle. They utilized coded language to track weekly settlements, with bookies earning a 25% commission on their bettors’ losses. Allegedly, Gerodemos also promised a 50% monetary incentive to certain individuals for successfully recovering gambling debts.
