Michelle Parker Mystery -- Ex-Fiance 'Primary Suspect' In 'People's Court' Missing Person Case

The ex-fiance of a woman who appeared on "The People's Court" has been named the primary suspect in her disappearance.

Orlando Police Chief Paul Rooney just announced Dale Smith is the target of the investigation.  Smith appeared with Michelle Parker on the show, arguing over the engagement ring.

Chief Rooney says Smith refused to take a polygraph test.

Parker's mother, Yvonne Stewart, made a plea during the news conference:  "If you could have avoided this Dale, if you had cooperated with the police and took a polygraph test when they asked you, you could have avoided a lot of stress ... We're not going to stop until we find out who did this."

Smith has been missing since November 17, the day the show aired.
