Investigators are sifting through "hundreds" of leads in the case of an Iowa co-ed who's been missing for more than two weeks, Fox News reported.
The July 18 disappearance of 20-year-old University of Iowa student Mollie Tibbetts remains the region's most high-profile case, the news outlet reported.
"We've been following up on leads. Those leads are in the hundreds," Kevin Winker, director of investigative operations at the Iowa Department of Public Safety, told Fox News.
A spokesperson from the state's Division of Criminal Investigation said investigators have even pulled resources from other cases to help in the search.
"Investigators from the Poweshiek County Sheriff's Office, the FBI, the Division of Criminal Investigation. There are an average 30 to 40 working this case a day," Winker told the news outlet.
"We've been searching ponds, fields, even from the air," he added.
The college sophomore was last seen on an evening jog; she'd been staying at her boyfriend's house, watching his dogs, while he worked a construction job in Dubuque about 100 miles away.
"Our position has not changed on the release of case facts, results and conclusions. I understand this is frustrating for many in the public and the media, but feel this is necessary for our investigation," Winker explained.
But the widespread interest in the case could help crack it, the young woman's family told Fox News.
A reward for information leading to the young woman's return is now over $220,000, Fox News reported.
