On January 11, 2008, Karas sentenced Olympic gold medalist
Marion Jones to six months in prison for making false statements after it was discovered that she had lied to federal investigators on two separate occasions: when she and
Tim Montgomery were being investigated over the
BALCO scandal and about her knowledge of fellow Olympian Montgomery's involvement in fraud.[5] On May 16 that year he sentenced Montgomery, who was also Jones' ex-boyfriend, to 46 months in prison for his part in a multimillion-dollar fake-check scheme.
In February and March 2015 Karas presided over
Malcolm Smith and
Dan Halloran's trials for corruption. Smith was convicted on bribery and extortion charges while Halloran was found guilty of various corruption charges, including taking bribes to aid Smith's
2013 campaign for
Mayor of New York City. He turned down the defense's appeal for leniency and sentenced Halloran to ten years in prison. The high-profile trials of Smith and Halloran were part of string of cases brought forward by federal investigators in an effort to curb political corruption within the New York state government.[6][7]
