College student Mollie Tibbetts disappeared from the small Iowa town of Brooklyn, Iowa, last week and her family pleads for clues and answers about where the 20-year-old woman has gone. Police believe the former high school track star may have been out jogging when she vanished.

Nancy Grace explores the mystery with Phil Vetrano, father of Long Island jogger murder victim Karina Vetrano, private investigator Vincent Hill, lawyer and psychologist Dr. Brian Russell — host of Investigation Discovery’s “Fatal Vows” series, Atlanta lawyer and juvenile judge Ashley Willcott, and Crime Stories contributing reporter Chuck Roberts.
