Authorities believe they have found the body of the University of Iowa student who was reported missing last month, the Associated Press reports. Mollie Tibbetts, 20, was last seen July 18, jogging in the town of Brooklyn, Iowa, near her home. She’d been dog-sitting for her boyfriend and her boyfriend’s brother, who say they were out of town, and it remains unclear if she ever returned to their home after her jog. The University of Iowa student’s family reported her missing the next day, sparking an enormous search effort. Police will provide more details about their discovery at a 6 p.m. ET press conference Tuesday.
