A former Atlanta attorney and his son were sentenced to nearly six years in prison Tuesday for a banking and investment scam that netted them more than $15 million, authorities said.

Donald Watkins and his son Donald Watkins Jr. were convicted earlier this year  of deceiving former NBA star Charles Barkley and using the name of former Secretary of State Condoleezza Rice to support the scam. Watkins was sentenced to five years in prison, while his son got 27 months behind bars, The Associated Press reported.

The elder Watkins was also ordered to pay $14 million in restitution.

During the trial, witnesses including Barkley testified about losing more than $6 million in investments and loans to the former attorney. Barkley said he was friends with Watkins, who split his time living in Birmingham, Ala. and Atlanta.

Other athletes who lost money in the scheme included former NBA player Damon Stoudamire and former NFL players Takeo Spikes and Bryan Thomas.

Rice testified that Watkins used her name to promote an energy business without her permission, the AP reported. She declined to get involved, but Watkins included her name in emails to investors anyway, she said.

As a lawyer, the senior Watkins once served in Montgomery as a city council member. He helped defend HealthSouth Corp. founder Richard Scrushy in a fraud that nearly bankrupted the company, now known as Encompass Health. He has also worked on various civil rights cases.

Watkins reportedly only had a net worth of few thousand dollars despite portraying himself as wealthy, the AP reported. He attempted to purchase a major league baseball team and the the St. Louis Rams before the team left for Los Angeles.
