MISSING COLLEGE STUDENT MOLLIE TIBBETTS IS ALIVE — HER FAMILY BELIEVES. PLUS, WIFE OF KILLER COP STACY PETERSON’S MISSING BODY FOUND — BY HER SISTER!

All Rise With Dylan Howard

Two blockbuster exclusive "All Rise" interviews.

The last time anyone saw Mollie Tibbetts, she was out for a jog in the small community of Brooklyn, Iowa, just east of Des Moines. Since then, investigators have fielded hundreds of tips. But the University of Iowa student is still missing.

The desperate search has led investigators to question a pig farmer who reportedly twice pleaded guilty to stalking, while a suspect in an assault on a jogger in another Iowa city and a man seen surreptitiously snapping pics of young girls on a run have also been analyzed for any possible connections.

But, so far, cops have come up empty.

We have the very latest — direct from her brother.

Plus, eleven heart-wrenching years after vanished, her body has been discovered — and her sister wants to can be tried for her murder. All Rise has learned Cassandra Cales used sonar technology to locate Stacy’s corpse at the bottom of the Chicago Sanitary and Ship Canal.

Now Cassandra hopes recovering Stacy’s body will lead to cops slapping new charges against her murderous brother-in-law, Drew Peterson.

The ex-cop, 64, is serving time for slaying his third wife, Kathleen Savio, and is the prime suspect in the disappearance of fourth wife Stacy. The mother of two was just 23 when she mysteriously vanished Oct. 28, 2007.
