DCI 'confident' on Mollie Tibbetts' digital footprint

State, federal, and local authorities are still searching for a missing 20-year-old University of Iowa student.

Mollie Tibbetts was last seen on July 18 in Brooklyn, Iowa where she was dog sitting for her boyfriend.

Yesterday, authorities searched two farms, even using a K9 unit at one of the locations. They still didn't find any more information as to where Tibbetts could be.

Iowa DCI says they are confident they've zeroed in on her digital footprint.

State, federal, and local authorities are looking into every lead they get and even reconducting interviews. Investigators say they're also retracing their steps, but they haven't found a person of interest at this time.

The DCI is encouraging people to avoid spreading rumors on social media, as they could slow down the search.
