Who Killed Elizabeth Collins and Lyric Cook-Morrissey in 2012?

It's a 12-year-long mystery that one community wants to be solved. The Iowa Department of Public Safety says in the summer of 2012, cousins Elizabeth Collins, 8, and Lyric Cook-Morrissey, 10, went out for a bike ride and never came home. Their bodies were found five months later in woods 25 miles away by hunters. Their families are still looking for justice. Inside Edition Digital’s Mara Montalbano has more.
