A federal jury has convicted former world class cyclist Tammy Thomas of perjury and obstructing justice for lying to a grand jury during the BALCO steroids probe.

Thomas was reportedly stoic as the jury’s verdict was read, but then lost it. She leapt to her feet as the jurors left the courtroom and began shouting at them: “Look me in the eye, look me in the eye. Look me in the eye and tell me you mean what you did. Look me in the eye. You can’t do it.”

Thomas also reportedly confronted the BALCO prosecution team as they left court, gesturing and shouting at lead prosecutor Matt Parrella. “Look me in the eye. You like to destroy lives,” she yelled at Parrella, who was pulled from the scene by fellow prosecutor Jeff Nedrow.

Thomas faces a sentence likely to range from one to three years in federal prison for the perjury and obstruction convictions. Sentencing is set for July 18.
