Former South Pittsburg Mayor Mike Killian and the man federal authorities say managed his illegal gambling operation, Barry Cole, pleaded guilty to gambling charges in Federal Court on Thursday afternoon.
Mark Angehr of the U.S. Justice Department's Public Integrity Section said they face up to five years in prison and fines up to $250,000.
Sentencing by Judge Curtis Collier was set for Jan. 9 at 9 a.m.
They remain free on bond.
The 56-year-old Killian, who was South Pittsburg mayor from 2005 to 2012, told Judge Collier he understood that the felony conviction means he cannot again run for public office and also loses his right to vote.
He is the brother of U.S. Attorney Bill Killian. For that reason, no member of the Bill Killian staff handled the prosecution.
Authorities said the operation began around 2002 and took in as much as $12 million in sports wagers.
Mike Killian was the owner of the Lotto Mart convenience store in South Pittsburg and also ran a fireworks store.
Authorities said video gambling, sports betting and outlaw lotteries all took place at the Lotto Mart.
Killian and Cole split the proceeds equally, it was stated.
Killian was represented by attorney Lee Davis and Cole by attorney Mike Little.
