Inside the $8M Illegal Bookmaking Operation Busted in Las Vegas

Las Vegas has no shortage of big bettors, but not all of them play by the rules. A 57-year-old man known locally as “Wild Bill” now faces a stack of felony charges. State and federal investigators accused him of running an illegal bookmaking operation in Las Vegas that funneled millions through an offshore website and licensed Nevada sportsbooks alike.

William West Roberts was arrested on April 21 after a multi-year investigation led by the Nevada Gaming Control Board and the FBI. Authorities allege he accepted bets through a Costa Rica-based website. At the same time, he placed large volumes of wagers at regulated Nevada sportsbooks. No attorney was listed for Roberts in available court records, and he is presumed innocent unless proven guilty.

How the Alleged Operation Worked

Illegal bookmakers face a straightforward problem. When a customer wins big, the bookie has to pay. To limit that exposure, operators sometimes place matching bets at legal sportsbooks. Investigators call this practice laying off or hedging. Authorities allege Roberts did exactly that, using licensed Nevada books as a pressure valve for his offshore business.

Casino records showed Roberts wagered around $8 million at Nevada sportsbooks during the investigation period. He also appeared in 334 cash transaction reports filed between 2022 and 2026. Those reports covered transactions totaling as much as $7.4 million. Financial institutions must file these reports for large cash movements, and they formed a key part of the paper trail investigators followed.

Authorities allege that money from the bookmaking operation moved alongside funds from two separate businesses. The first was Ace’s Family Fitness, a gym in northwest Las Vegas. The second was Wild Bill Consulting Inc., a handicapping and sports tips venture. Roberts marketed paid betting picks and subscription advice under the Wild Bill name. Investigators concluded that the financial records from those businesses did not account for the funds Roberts used for casino wagering and personal expenses.

Charges and Court Date

Roberts faces several felony charges. These include operating a gaming establishment without a license, disseminating racing information without a license, and receiving compensation for bets without a gaming license. He also faces gross misdemeanor counts of accepting unlawful wagers in Nevada and attempted money laundering. A misdemeanor count tied to an unlawful wager from outside the state rounds out the charge list. He posted bond and returns to court on May 12.

Multiple financial institutions closed his accounts during the investigation, citing suspicious activity. Casinos also flagged irregularities in his transactions. Investigators said those patterns helped sustain the operation across several years.

A Tip From a Former Partner

The investigation did not begin with regulators spotting an anomaly. It started with a tip. Roberts’ former girlfriend contacted authorities by email. That message prompted the Nevada Gaming Control Board and FBI to open their inquiry. Investigators later brought in a confidential human source and undercover operatives who posed as gamblers. Roberts was reportedly recorded discussing the alleged operation during that phase.

The case reflects an enforcement pattern Nevada regulators have pursued with growing consistency. Illegal bookmaking in Las Vegas concerns state authorities for a specific reason. The presence of licensed sportsbooks creates infrastructure that unlicensed operators can exploit. Using legal books to hedge liabilities leaves a financial trail, and investigators know how to follow it.

Nevada Keeps Pressure on Unlicensed Betting

This case fits within a broader enforcement push across Nevada. Regulators have moved against platforms and operators that blur the line between licensed and unlicensed activity. The Roberts arrest shows enforcement reaches individual-level operations, not just large corporate actors.

The scale here is notable for a one-person setup. Eight million dollars in sportsbook wagers and nearly as much again in flagged cash transactions is serious volume for a solo bookmaking business. It ran out of a gym and a handicapping website. It also shows how far regulators will go when the financial trail is clear enough to follow.

Roberts returns to court on May 12. No criminal complaint had been filed as of the time of reporting.
