Remains believed to be that of Mollie Tibbetts, missing University of Iowa student, have been found after more than a month long search, according to reports.

The Associated Press reported Tuesday, that Crime Stoppers of Central Iowa learned of her death from a member close to the Tibbetts’ family. Their source, Greg Willey, said it was a “tough” end to the case.

Crime Stoppers of Central Iowa, the Iowa Department of Criminal Investigation and the Poweshiek County Sheriff’s office could not confirm the findings when reached by the Daily but said there would be a press conference at 4 p.m.

A reward fund was created for Tibbetts’ safe return, surpassing $400,000. Willey told AP the fund will likely go to tips leading to the arrest of the person responsible for Tibbetts’ death.

“Once they catch their breath, this will turn into a weapon going the other direction to catch the person who did it,” Willey told AP.

Tibbetts has been missing since July 18 after dog sitting for her boyfriend, Dalton Jack, at his house in Brooklyn, Iowa.

Her last known communication with anyone was around 10 p.m. that night — a Snapchat message shared between Tibbetts and her boyfriend, Kriegel said. Her boyfriend has said the Snapchat message appeared to be indoors.

UPDATE: A press conference will be held at 4 p.m. according to a press release from the Iowa Department of Public Safety. The press release says the only information currently available is that a body has been found in rural Poweshiek county and is being identified by law enforcement.
