CHICAGO (WLS) --Just a week after Drew Peterson got another 40 years behind bars, he's suing to get his police pension back.
The Bolingbrook Police Department stopped paying the retired cop in June, saying he used his training to murder his third wife, Kathleen Savio.
Peterson is serving 38 years for the killing. Last Friday, 40 years were added to his sentence because he tried to put a hit on the state's attorney who got him convicted, James Glasgow.
Peterson's lawyer said there is no link between the murder and his client's 30 years on the police force.
