There was an unconfirmed sighting of Mollie Tibbetts, the 20-year-old University of Iowa student who disappeared on July 18, while she was dog-sitting at her boyfriend’s house in Brooklyn, New York.

The Kearney police conducted a search of the area around a truck stop where Tibbetts was reportedly seen on July 26, spoke with witnesses and reviewed any potential surveillance video that might lead them to clues as to where the missing jogger was. The area where she was reportedly sighted was 230 miles away from the place she was last seen, local radio WSPY News reported.

However, Tibbetts did not show up in any of the security footages analyzed by the police. The only source of the sighting was a man at the truck stop who claimed to have seen a woman who resembled the physical appearance of the missing jogger.

A report regarding the possible sighting was sent to the investigative task force by the Kearney police department. No other details regarding the sighting were released by the police.

Kevin Winker, the director of investigative operations for the Iowa Department of Public Safety, said in a press conference Monday that he was "not going to draw any conclusions about the circumstances of her disappearance other than it's not consistent with her past.”

He added that investigators will be exploring every possible avenue to track down the jogger’s whereabouts, including gathering information from her Fitbit device, which she was wearing when she was last seen jogging through the town wearing black running shorts, a pink or red running top and running shoes, on the night of July 18.

The Tibbetts family has offered $30,000 for any information that could lead to the safe return of their missing member. Funding for the reward mostly comes from donations from people. For this purpose, they have set up a reward account at Brooklyn's First State Bank, 104 Jackson St., P.O. Box 532. Anyone who is interested in donating money toward the cause can do so via wire and mail, Des Moines Register reported.

Rob Tibbetts, Mollie’s father urged people with any information pertaining to the case to step forward and help out. “It doesn’t matter what we’re going through, we just need people to think -- because somebody knows something and they don’t even know it’s important,” he said.

Jake Tibbetts, Mollie's brother, told Fox News: “We know she is fighting as hard as anyone to get back home,” he said. “It’s a process and we wish it wasn’t so long, but good things take time, and getting her home will be a really good thing.”

““We have full faith in the authorities, that they are going to do the best job they can," he added. "They have been brought in for a reason, because they are the best at what they do. We have a lot of faith in them.”
