Body of young white woman found in Iowa not missing college student Mollie Tibbetts

The body of a young white woman found in Iowa does not belong to missing college student Mollie Tibbetts, authorities said Sunday.

The woman, believed to be in her early to mid-20's, was found in rural Lee County, about 100 miles from where Tibbetts was last seen on July 18 in the small town of Brooklyn.

"Investigators are keenly aware of the Mollie Tibbetts investigation and have no reason to believe that the decedent is that of Mollie Tibbetts," the Iowa Department of Public Safety said.

Special Agent Rick Rahn told the Des Moines Register that they have identified the body and are in the process of notifying relatives. The death is considered suspicious, he told the newspaper.

Authorities are looking into 200 tips in connection to Mollie's disappearance, but have not said much about the investigation.

"As leads come in, and information is evaluated, the investigative team responds to those and prioritizes those," Kevin Winker with the Iowa Department of Public Safety told CBS News. "I would expect those searches to continue."

Local pig farm owner Wayne Cheney says he has been questioned twice about Tibbetts. Cheney had two convictions for stalking, according to WHO.

"I don't even remember what they asked me. It was a waste of my time, I know that," he told the station.

Winkler tells CBS News that "we're not in a position to say who is a suspect, who isn't a suspect, or that there are suspects." He declined to say whether a red shirt that may have been worn by Tibbetts was found.

A reward in Mollie's case has ballooned to $260,000. Anyone with information should call CrimeStoppers at (515) 223-1400.
