The father of Mollie Tibbetts pleaded for anyone with any semblance of information to come forward in hopes of finding his missing daughter.

Tibbetts has been missing for just more than two weeks after being last seen jogging on the evening of July 18 in the town of Brooklyn, Iowa.

Rob Tibbetts appeared alongside his daughter's boyfriend, Dalton Jack Thursday on "Fox & Friends" and said no information is insignificant.

"If they have nothing to hide, they have nothing to fear," he said.

Former homicide detective and Fox News contributor Ted Williams said Thursday that law enforcement is going full speed ahead with their search for Tibbetts.

"They are moving with all deliberate speed to try to bring Mollie home," he said.

Williams said that police are using K9s and "experts" in their search. He added that authorities have received more than 200 tips in the case.

"They are running down each and every one of these tips."

Although unconfirmed, police said Tibbetts was possibly seen at a truck stop in the Kansas City area.

"I've seen this happen before, where there have been second sightings," Williams said. "Sometimes they work out and sometimes they don't, but what we want the public to do is to continue to bring in those various leads."

Tibbetts' mother, Laura Calderwood, spoke at a news conference Thursday after remaining behind the scenes for the past few weeks. She said the family has raised about $172,000 for a reward fund for tips leading to Tibbetts.
