OKLAHOMA CITY (AP) - A judge, prosecutor and former drug court coordinator in Pittsburg County have been indicted for conspiracy against the state by Oklahoma's multicounty grand jury.

An indictment unsealed Friday in Pittsburg County accuses Special Judge William H. Layden Jr., Assistant District Attorney James Michael Miller and former drug court coordinator Angela Marcum of attempting to obstruct an investigation of alleged embezzlement within the county's drug court program.

The indictment says that in April 2010, former District Attorney Jim Bob Miller asked authorities to investigate allegations that money received by the drug court program had not been deposited. The three indicted are accused of withholding evidence and harassing witnesses.

Marcum was indicted in June for allegedly embezzling more than $25,000 from the drug court program.
