PHIL show Exhuming a body for more testing has proven to be successful. When Illinois police officer Drew Peterson's fourth wife, Stacy, vanished, investigators exhumed the body of his third wife, Kathleen Savio. Savio's death had been ruled an accidental drowning, but a second independent autopsy concluded she had been killed."Well, it's definitely not too late for things like DNA and toxicology," said former San Diego police detective Rick Carlson.Carlson said a forensic pathologist can also look for fingernail scrapings and skeletal damage not found during the first autopsy.Carlson said it may be what the family needs to feel it did all it could for Zahau."It's at least maybe the satisfaction of the family that they're looking into it themselves and having some participation in the final determination," said Carlson.10News contacted the San Diego County Sheriff's Department to find out their thoughts on Dr. Phil's possible involvement, but a spokesperson said the department had no comment.
