SAN FRANCISCO -- A federal judge has sent Barry Bonds' former trainer to jail for refusing to testify at the slugger's perjury trial.
U.S. District Judge Susan Illston found Greg Anderson in contempt Tuesday and ordered him held in custody until he testifies or the trial ends, which could be as long as four weeks.
Prosecutors allege Anderson provided Bonds with performance-enhancing drugs and detailed instructions on how to use them. His refusal to testify has undercut a significant portion of the government's case against Bonds because the judge has ruled much of the evidence tied to Anderson is off limits.
Anderson served more than a year in prison for refusing to testify in 2006 before the grand jury investigating the home-run record holder. He also served three months in prison after pleading guilty in 2005 to steroid distribution and money laundering.
