An Idaho man released on bond after pleading guilty to a lesser charge in the disappearance a Washington woman and agreeing to testify against her estranged husband is back in custody.

The Lewiston Tribune reports in a story on Thursday that David C. Stone is being held in the Latah County Jail after allegations he telephoned a witness on Tuesday.

Second District Court Judge Jeff Brudie is determining if Stone's conditions of probation should be modified or revoked.

Stone pleaded guilty in December to failure to notify law enforcement about a death after Rachael Anderson of Clarkston, Wash., went missing in 2010. Her body hasn't been found.

Stone's guilty plea is part of a deal that calls for him to testify at Charles A. Capone's first-degree murder trial.
