On Thursday, investigators once again searched fields and ditches near Brooklyn, Iowa, where the 20-year-old vanished more than two weeks ago.
Her family reported her missing the next day after she didn't show up to work. "They've put together a very sophisticated investigation", he said of the police.
Rahn declined to say at the time whether investigators have found her FitBit or if they know its location.
Last Friday that led them to the pig farm near the wildlife reserve where they searched a home and a garage, reportedly without a warrant, Fox News said.
But again he declined to say whether Tibbetts is believed to have returned home safely from a jog that evening.
When asked if authorities suspect that Tibbetts was abducted, Winker said, "We don't know where Mollie is at right now".
Anyone with information is encouraged to call Crime Stoppers of Central Iowa at 1-800-452-1111.
According to police, officers responded to a possible sighting of 20-year-old Mollie Tibbetts on Thursday, July 26, at a truck stop in their jurisdiction.
"She's out there. We feel it". She said that it's the family's greatest hope that whoever may have Tibbetts lets her go and claims the "money we have raised for her freedom". Her boyfriend, Dalton Jack, was the last person to hear from Tibbetts.
"We believe Mollie is still alive and if someone abducted her, we are pleading with you to please release her", she told the press.
"Sometimes I just feel her sitting on my shoulder", she said. "I don't know that I have the strength in me, and Mollie's lending me her strength". Initially, they said she was wearing a black sports top - but now say the top was pink. Investigators have reached no conclusions about why she has disappeared. "We are very hopeful with the electronic data we are getting back", Mitch Mortvedt, assistant director of the Iowa Division of Criminal Investigation, previously told the Des Moines Register.
