Court upholds perjury conviction

SAN FRANCISCO -- A federal appeals court has upheld the perjury conviction of a former world-class cyclist for lying to a grand jury about her steroid use.

Tammy Thomas was one of 30 athletes called before a federal grand jury in 2003 as part of the federal government's investigation of a San Francisco Bay Area-based steroids distribution ring. Thomas denied taking steroids even though several urine samples that she provided during competition tested positive.

On Thursday, the 9th U.S. Circuit Court of Appeals upheld a lower court verdict that Thomas knew she was lying when she denied taking steroids in response to direct questions.

She was sentenced to six months of home confinement after her 2008 conviction.

Former baseball player Barry Bonds has pleaded not guilty to similar charges.
