An attorney for Drew Peterson has turned over new photos exclusively to FOX News that he says might be of Peterson's missing fourth wife Stacy.
The lawyer told FOX News' John Gibson and Heather Nauert of "The Big Story" that he got the pictures from a retired police officer who said he saw Stacy Peterson in Thailand.
Drew Peterson says he can't be 100 percent sure that the photos are of his missing wife, who vanished in October and is presumed dead. Peterson is a prime suspect in her disappearance.
Also Thursday, Peterson, a former Illinois police sergeant, said he wanted to divorce Stacy. He has insisted that his wife is alive but ran off with another man.
Peterson's third wife, Kathleen Savio, died under mysterious circumstances in 2004, when she was found in a bathtub. Her body was exhumed for further forensic analysis, and officials have reclassified her death as a "homicide staged to look like an accident."
