Search for missing Iowa student Mollie Tibbetts continues
Authorities have intensified their search for missing 20-year-old University of Iowa student Mollie Tibbetts.
Federal investigators have interviewed residents in and around the town of Brooklyn, where Mollie lived.
One of those is interviewed is 56-year-old Wayne Cheney, who lives in a trailer home about 500 yards from a pig farm investigators searched more than a week ago. Cheney told ABC News the FBI questioned him Friday.
Cheney has a criminal past, convicted for stalking and harassment, but he says he's never met Mollie or her family, and he has not been named a person of interest.
Investigators continue to question others
Tibbetts vanished while out for a run in Brooklyn more than two weeks ago. She had been living with her boyfriend for the summer. He was working a construction job 100 miles away when she disappeared. Police say he is not a suspect.
Mollie's family refuses to lose hope that they'll find her alive.
"You cant give up hope. If it were me that were missing, Mollie wouldn't give up hope," said Laura Calderwood, Mollie's mother.
Sunday, authorities found the body of a young woman they thought might be Mollie, but it is not. Their search for her continues.
