An Iowa hog farmer with two past stalking charges was questioned by authorities looking into the disappearance of the college student who vanished two weeks ago, according to a report.

Deep River resident Wayne Cheney admitted to local channel WHO13 that he was questioned for hours by officials investigating the case of 20-year-old Mollie Tibbetts, who was last seen jogging through Brooklyn, Iowa, on July 18.

“They took me down to the fire station Tuesday and questioned me for two hours,” Cheney said. “I don’t even remember what they asked me.”

Investigators combed through the pig farm, which is within walking distance of Cheney’s home. They also took photos of the interior of his house and searched his garage, Fox News reported.

“I just thought it was a waste of time, but oh well,” he said.

The farmer said investigators kept his cellphone overnight to check his records and added he “has nothing to hide.”

Iowa records show Cheney has pleaded guilty for stalking twice, once in 2009 in Poweshiek County and once in Marion County four years ago.

The state Division of Criminal Investigation wouldn’t confirm or deny whether Cheney was interrogated and whether he was a suspect.

Cheney told the station he doesn’t know the Tibbetts family and hopes Mollie is found soon.
