Boyfriend of missing Iowa college student says 'it gets harder day by day'
The boyfriend of missing Iowa college student Mollie Tibbetts spoke about how hard it has been since she disappeared.
"Initially, it was shock and then, you know, it gets harder day by day because she's still not here and you miss her, you miss her more than anything in the world," Dalton Jack said in an interview.
Jack, who working a job in Dubuque, Iowa, on the night Tibbetts went missing, is not a suspect in the investigation.

Tibbetts, 20, was last seen jogging on the evening of July 18 in Brooklyn, Iowa, said Kevin Winker of the Iowa Department of Public Safety. Tibbetts was believed to be wearing dark running shorts, a pink sports top and running shoes, according to police.
She was reported missing the following day after not showing up to her job at a day care.
"She's not going to run off," Jack said in an interview. "I try not to speculate on it too much because the only thing that comes into your head whenever you're not investigating all the facts is that something bad happened and you don't, I personally don't want to believe that."
Investigators are looking to explore Tibbetts' digital footprint, specifically looking at a Fitbit device which she would have been wearing during her jog, according to NBC affiliate KWWL.
