A suburban Chicago police sergeant said he had nothing to do with his fourth wife’s disappearance and claimed the woman is no stranger to disappearing acts, the Naperville Sun reported Thursday.

Bolingbrook police Sgt. Drew Peterson said Stacy Ann Peterson, 23, who has been missing since Sunday, has run off before after he or the couple’s children got to be too much for her, the Sun reported. Drew Peterson claimed she may be following in the footsteps of her mother, who vanished eight years ago and has not been seen or heard from since.

Police entered the Peterson home Thursday with sniffing dogs, and impounded two vehicles from the driveway. They have also begun questioning Drew Peterson. The couple's two children were reportedly staying with a neighbor.

Drew Peterson maintains that Stacy Ann is "where she wants to be." When asked if she removed anything from the house before leaving, he told FOX News she took cash, a passport and a bikini.

Drew Peterson is on paid leave from the force but still carrying his badge and gun. He was fired from the department more than 20 years ago after being found guilty by the village board of police and fire commissioners of disobedience, conducting a self-assigned investigation, failure to report a bribe immediately and official misconduct, the Chicago Sun-Times reported.

Just two months before, he had been indicted on charges of official misconduct and failure to report a bribe. Officials at the time said he allegedly had solicited drugs in exchange for information.

Authorities announced this week they have reopened an investigation into the death of Peterson's third wife, Kathleen Savio, who was found dead in a dry bathtub after drowning in 2004. The coroner had ruled Savio’s death accidental, and the case was closed later that year.
