Drew Peterson has been charged with trying to hire someone to kill the prosecutor who led the 2012 trial that resulted in the former police officer being convicted of killing his third wife.

State and local prosecutors said Monday that Peterson is charged with solicitation of murder for hire and solicitation for murder after allegedly trying to hire someone to kill Will County State's Attorney James Glasgow while Peterson was in prison.

The 61-year-old is serving a 38-year prison sentence after being convicted in the 2004 drowning death of Kathleen Savio.

An investigation into Savio's death was reopened after Peterson's fourth wife, Stacy, disappeared in 2007. Authorities have said they believe Stacy Peterson is dead and that Drew Peterson is a suspect, but he hasn't been charged in that case.
