In the spring of 1981, with tape recordings and plea agreements in hand, FBI agents fanned out across the state and gave commissioners the chance to turn themselves in. In the first week, Gibbons said thirty or forty commissioners agreed to plead guilty to one count of conspiracy to commit mail fraud and obstructing the IRS. By July 1981, 100 people had signed a plea agreement. In most cases, commissioners who agreed to cooperate with the government received probation or one or two years in jail. Others who decided to take their cases to trial ended up serving jail time anywhere from seven up to 20 years.
The list of suspects grew longer and longer and investigators saw the pattern of fraud winding its way down from northwest Oklahoma to the southwest part of the state and then into north Texas.
By the end of the investigation several years later, there were around 280 total fraud convictions, including thirty or forty people in Texas.
"Number wise, this was the biggest political corruption case in FBI history," Gibbons said.
