Where Is Mollie Tibbetts? FBI Investigates Lincoln Wildlife Reserve In Iowa

In a latest development, agents from the FBI returned to search a pig farm, near the Lincoln Wildfire Reserve in Brooklyn, Iowa, a second time on Thursday, after having scanned it last week in search of missing university student Mollie Tibbetts.

According to Fox News, a piece of red cloth was found by someone mowing the lawn in the farm, which led FBI to revisit the area for any possible clue that could point to the whereabouts of Tibbetts.

Although it is not yet clear if the red cloth belonged to the missing woman, an employee from the daycare center that Tibbetts worked in confirmed they wear red shirts at the facility, according to the report.

Also, Tibbetts was last seen wearing black running shorts, a pink or red running top and running shoes, on the night of July 18, before she went missing.

Search teams were deployed in the pig farm, where they were looking through ditches about a mile away from the reserve on Thursday. Last Friday was the first time FBI combed through the region, although it is unclear what led them to the farm that time.

According to a pig farmer, investigators thoroughly searched the place for two hours without a warrant, taking photos of the interior of the home and also checking his garage. FBI also allegedly questioned the farmer and seized his cellphone, keeping it overnight to look through his records.

The farmer added that he had “nothing to hide” and was formally charged by the FBI.

Meanwhile, the reward for any tips that could lead to the safe return of Tibbetts has sprung up to $172,000. Funding for the reward mostly comes from donations from people. For this purpose, the missing jogger’s family had set up a reward account at Brooklyn's First State Bank, 104 Jackson St., P.O. Box 532. And with the story of the university student pulling at people’s heartstrings, donations have been pouring in generously, both from individuals and businesses from Fresno, California, including Valley Crimestoppers.

"As of 10 this morning we have raised $172,000 that would be paid to you as soon as Mollie is safely home," said Laura Calderwood, mother of Tibbetts at a press conference Thursday, local news outlet Your Central Valley reported. "We believe Mollie is still alive and if someone has abducted her we are pleading with you to please release her.”

The missing student's father, Rob Tibbetts, added: “If you have nothing to hide you have nothing to fear. Come forward share that information with the authorities and lets bring Mollie home."

A vigil was organized at the RiverLoop Amphitheatre & Expo Plaza in Waterloo, Iowa, on Wednesday to show support to Tibbetts. More than 200 people attended the gathering, including police chiefs from the area and two state representatives.

"There is evil is lurking among us,” Waterloo Police Chief Dan Trelka, directing a warning to the predators: "We will hunt you down to the ends of the earth."

Tibbetts' cousin Morgan Collum, 27, was also present at the gathering. She thanked the crowd for supporting her family and added it had been a really difficult time for everyone who knew her missing relative. "How am I going to get through this day?" she said she tells herself this every day, Des Moisnes Register reported.
