The boyfriend of an Iowa college student who went missing after a jog two weeks ago is holding out hope that she is OK. Dalton Jack, 20, spoke out about the disappearance of Mollie Tibbetts from the small town of Brooklyn, Iowa on July 18 after the case sparked nationwide attention. “The only thing that comes into your head when you’re not investigating, don’t have all the facts, is that something bad happened,” he said in an interview on NBC’s Today Show Thursday.
