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.
Drew Peterson, a former Bolingbrook, Ill., police officer, accompanied the investigator inside the house and limited the officer's access to drawers and his two vehicles, Callaghan testified.
In earlier testimony Wednesday, a doctor who treated Savio said he knew of no medical reason that would have caused the woman to slip and fall in a bathtub. Savio's 2004 death, ruled an accident at the time, was reclassified as a homicide after Stacy Peterson disappeared in 2007.
