JOLIET, Ill., Jan. 27 (UPI) -- Drew Peterson was not cooperative with police after the disappearance of his fourth wife, an Illinois State Police special agent testified Wednesday.
Special Agent Patrick Callaghan -- testifying at a pretrial hearing to determine what hearsay evidence will be allowed in Peterson's trial on charges he allegedly killed his third wife, Kathleen Savio -- said Peterson only would allow one investigator into his suburban Chicago home the day his fourth wife, Stacy Peterson, was reported missing, the Chicago Tribune reported.
