BOLINGBROOK, Ill. —  Bolingbrook's police and fire commission has accepted the resignation of a former sergeant who is a suspect in his wife's disappearance.

Drew Peterson can now begin collecting a $6,000-a-month pension.

Peterson submitted his resignation last week, but Police Chief Ray McGury refused to accept it, saying he wanted Peterson fired.

McGury isn't disclosing specifics, but says alleged Peterson committed "severe" violations of departmental policies.

But the commission says it has no choice but to accept Peterson's resignation.

Peterson's wife, Stacy, was last seen October 28.

The investigation into her case has caused prosecutors to reopen the investigation into the death of Peterson's third wife, Kathleen Savio, whose body was found in a bathtub in 2004.
