At sentencing, each could be ordered to spend up to a year in federal prison.
Loveland, 65, admitted Tuesday to two felony counts connected to his involvement in the illegal Internet sports betting business. Prosecutors agreed to drop two other counts against him. He faces up to seven years in prison.
Loveland told the judge he put 16 friends on the Internet betting site in 2010 for them to gamble. He said six to eight friends would bet every week.
“If they won, I went and paid them. If they lost, I went and collected,” he said.
Loveland said he also helped Teddy Mitchell collect lost bets.
Last week, Teddy Mitchell, 58, pleaded guilty to involvement in the illegal Internet site and to a money-laundering conspiracy. His oldest son, Dryden R. Mitchell, 32, also pleaded guilty to involvement in the illegal Internet site and to money laundering. They will be sentenced in about three months.
An admitted bookie from California and an admitted bookie from Nevada pleaded guilty earlier this year and are awaiting sentencing. The final defendant, an Oklahoma City man, is expected to plead guilty later this month.
The gambling case has attracted widespread public attention because Mitchell's wife, Julie, 34, was brutally beaten to death in their home in November 2010. Teddy Mitchell was traveling out of the state at the time.
The homicide remains unsolved.
The FBI reported in court papers that Julie Mitchell acted as a card dealer in the poker games.
One witness told the FBI that Teddy Mitchell's driveway and yard were full of vehicles used by gamblers involved in the poker games on Tuesday and Thursday nights. The witness also reported the gamblers played on professional poker tables and catered food usually was provided.
