Lawyer for Drew Peterson hails FBI joining in search for missing woman

The lawyer for Drew Peterson is hailing the joining of the FBI in the search for the man's missing wife.

Attorney Joel Brodsky says he hopes the arrival of the federal agents will end the "witch hunt" against his client. Brodsky would not identify who he believed was leading the witch hunt, saying only that "people can draw their own conclusions."

Authorities are investigating the disappearance of Peterson's fourth wife, Stacy, and the 2004 drowning of his third wife.

Peterson has not been called a suspect in Kathleen Savio's death, but authorities have said they suspect him in Stacy Peterson's disappearance. He denies any wrongdoing and has proclaimed his innocence .

Illinois State Police have assigned more than five dozen investigators to work both cases, calling it the agency's top investigative priority.
