Las Vegas built its reputation on control. Cameras cover the casino floor and Nevada regulators track the money flowing through the industry. The record shows repeated failures inside that system, from organized crime skimming cash in the 1980s to suspicious VIP gambling at major Strip resorts decades later.
In 2025, Resorts World Las Vegas, MGM Resorts International and Caesars Entertainment faced nearly $27 million in combined Nevada fines over their handling of Mathew Bowyer, a California-based bookmaker. Regulators described years of gambling activity, warnings and unverified funding.
The cash behind the casino
Operation Strawman provided one of the clearest records of organized crime inside Las Vegas casinos. On October 15, 1983, federal authorities announced indictments against 15 major organized-crime figures. Investigators said more than $2 million had been skimmed from the Stardust and Fremont before the revenue reached official books.
The indicted figures included Chicago mob bosses Joey Aiuppa, Jackie Cerone and Angelo LaPietra. Frank "Lefty" Rosenthal ran the Stardust, Fremont, Marina and Hacienda for mob interests through front companies and informal arrangements. Martin Scorsese later used Rosenthal as the basis for Sam Rothstein in Casino, while the documented scheme depended on an ordinary accounting step: cash was removed from counting rooms before the casino reported its revenue.
The arrangement gave mob figures untaxed income and left regulators working from figures that had already been altered. Federal investigators described Operation Strawman as the first successful penetration of organized crime inside Las Vegas casinos.
Insiders and surveillance gaps
In 1992, Stardust sportsbook cashier William John Brennan disappeared with $500,000 in cash and chips. He handled cash and chips every day and was never found.
The Bellagio faced a different kind of failure from August 2012 to July 2014. Mark Branco, James Cooper, Anthony Granito and Jeffrey Martin ran a craps scheme that stole $1.2 million. Investigators found the fraud only afterward, by reviewing hundreds of hours of surveillance footage. All 4 men were later convicted and placed in Nevada's Black Book.
Cameras recorded the fraud for almost 2 years inside one of the Strip's most monitored properties. The same gap appears in money-laundering cases: a casino may possess extensive records while failing to investigate the activity those records contain.
The Bowyer cases
Resorts World Las Vegas was fined $10.5 million in March 2025. The Nevada Gaming Control Board complaint, filed on August 14, 2024, said Bowyer gambled there on 80 separate days over roughly 15 months and lost more than $6.6 million. Regulators also named bookmaker Damien Leforbes and alleged that the sources of funds for the customers were not properly verified.
Resorts World gave Bowyer gifts, discounts and flights on the casino's private jet, the complaint said. Genting Berhad, a Malaysian conglomerate headquartered in Kuala Lumpur, owns Resorts World Las Vegas. Regulators said the perks continued while the casino had not established where the gambling funds came from.
MGM's case extended across a longer period. In April 2025, the Nevada Gaming Commission approved an $8.5 million fine involving Bowyer and Wayne Nix, a former minor league baseball player identified as an illegal bookmaker. Regulators said MGM executives had concerns about Bowyer's income as early as 2015. In 2018, an outside customer warned MGM that Bowyer was using its properties to recruit other gamblers.
Former MGM executive Scott Sibella was involved in the leadership failures described in the complaint. His gaming license was separately revoked in December 2023. Bowyer continued cash-heavy gambling at MGM properties while those warnings remained unresolved.
7 years at Caesars
Caesars Entertainment accepted a $7.8 million settlement approved by the Nevada Gaming Commission on November 20, 2025. Regulators alleged that Bowyer gambled at Caesars properties in Paradise, Nevada, from 2017 through 2024. In 2017 alone, he wagered and lost more than $3 million. Caesars did not ban him until January 2024.
Nevada Gaming Commissioner Brian Krolicki called Bowyer a "wrecking ball that continues to leave havoc" across Strip compliance programs. Commissioner Rosa Solis-Rainey voted against the settlement because she did not believe the amount was "on par" with earlier agreements. Caesars leadership described the company as "embarrassed" by its connection to the bookmaker.
The 3 penalties total nearly $27 million over the companies' handling of the same customer.
