A prison informant testified last week that Peterson enlisted him to plot the death of Will County State’s Attorney James Glasgow. The prosecutor helped convict Peterson in 2012 in the killing of Peterson’s third wife, Kathleen Savio.

Peterson is serving a 38-year sentence and faces up to 60 more years in prison.

Prosecutors say Peterson believed he would be able to successfully appeal his conviction in Savio’s death if Glasgow was dead.

Peterson’s court-appointed public defender has dismissed the secret recordings of his client arranging for the hit with informant Antonio “Beast” Smith as exaggerated prison boasts. The lawyer also attacked the informant’s credibility.
