Mollie Tibbetts, a 20-year-old University of Iowa student, went missing in the small town of Brooklyn after she left a house where she and her boyfriend had been dog sitting, ABC News reported.
“She might have a FitBit on and she might have her cell phone, but obviously we’ve tried just calling her but it’s either off or dead so it would go straight to voicemail,” her boyfriend Dalton Jack told the network.
Tibbetts was last seen wearing a black sports bra, gym shorts, and running shoes while on her job Wednesday night, according to the local sheriff’s office.
The Poweshiek County sheriff’s office said they are working with several other agencies to search for her.
The area near Brooklyn is largely farmland, with acres of dirt roads and cornfields. Hundreds of volunteers fanned out across the region on Friday and Saturday to help search for Tibbetts, according to ABC.
“This is not like her at all,” Tibbetts’ aunt Kim Calderwood told local ABC affiliate WOI. “She’s a very responsible and conscientious young woman.
“We miss you, we’re looking for you and we will never stop,” Calderwood added.
