JOLIET, Ill. (AP) — Despite being recently sentenced to prison for plotting to kill the man who originally put him behind bars for murdering third wife Kathleen Savio, former suburban Chicago police officer Drew Peterson is trying to keep his pension.

Peterson has asked a Will County judge to reverse the Bolingbrook Police Pension Board’s decision to stop his $79,000-per-year payout. The board made the decision in June after Peterson was convicted in a murder-for-hire case targeting State’s Attorney James Glasgow.

Last week, a Randolph County judge sentenced Peterson to an additional 40 years in prison for trying to hire a hit man while incarcerated at Menard Correctional Center.

The Chicago Tribune reports in a petition filed Tuesday, Peterson attorney Steven Greenberg argues the “mere conviction of a felony is insufficient to justify forfeiture of pension benefits ….”
