Mollie Tibbetts, Missing Iowa College Student, Found Dead

Her family reported her missing the following day when she didn't show up for work. Her disappearance set off a massive investigation and weeks of fruitless searches.

Last week, authorities said they were focusing their investigation on five areas in and near Tibbetts' hometown. Those areas reportedly included her boyfriend's home in Brooklyn, a car wash, a truck stop, a farm more than three miles from downtown Brooklyn, and another farm more than six miles away.

In an interview earlier this month, Mollie Tibbetts' father said he believed his daughter may have left willingly with someone she knew.

"I think someone went to the house that Mollie knew or that Mollie trusted and that she left with them willingly," Robert Tibbetts told CBS News correspondent Adriana Diaz. "Now they're in over their head and they don't know what to do."

He says if he could talk to his daughter, he would tell her to "hang on."

"We're gonna come get you," he said. "Everybody's looking."

Police have scheduled a news conference for 6 p.m. ET Tuesday to provide an update on the latest developments. So far, no details have been released about where she was found or what the cause of death might be.

This is a developing story and will be updated.
