Missing Iowa student Mollie Tibbetts' body found, authorities believe

BROOKLYN, Iowa -- More than a month after Iowa college student Mollie Tibbetts went missing, authorities believe they have found her body, AP reports.

A body was discovered on Tuesday, Greg Willey, the vice president of Crime Stoppers of Central Iowa, told AP. He said they believe it is Mollie Tibbetts.

In a press release, authorities confirmed that a body was found but said they were working to confirm the identity. The body was found in rural Poweshiek County, Iowa, the same county where Tibbetts' town of Brooklyn is located.

Tibbetts was last seen on the evening of July 18 while on a run in Brooklyn, Iowa. The 20-year-old was living with her longtime boyfriend, Dalton Jack, and his brother for the summer. Both brothers were out of town that night, and authorities earlier stated that neither was a suspect in her disappearance.

A reward fund meant for information leading to her safe return broke local records, reaching nearly $400,000. Willey said that money will now go toward information leading to the capture of any suspects.

Mollie Tibbetts' father, Rob, went home to California over the weekend after coming to Iowa soon after she went missing to help with the search. He had expressed hope that they would still find her.

"We'll still find Mollie and bring her home, and I still feel that way. We all still feel that way," he said on Saturday. "That's why it's difficult for me to leave, knowing that there's a good chance we're going to bring her home, and I want to be there when she arrives."

On Tuesday, Rob told ABC News he did not have any comment to make at this time.

Authorities have not yet released any more information about the discovery.
