FREDERICK, Md. —  A man whose house was damaged by a tornado (search) was in jail Monday after repair workers found a large amount of child pornography and called police.

Robert L. Medvee (search), 52, of Frederick, was charged Friday with 48 counts of creating computer images of child pornography and 48 counts of possession of child pornography, Deputy Jennifer Bailey said.

Medvee, a hospital admissions clerk, remained behind bars in lieu of $96,000 bail after a bail review hearing Monday in Frederick County District Court.

The seized material — computer discs, videotapes and photographs — filled 20 to 24 boxes, Frederick County State's Attorney Scott Rolle said.

"It was the largest seizure of child pornography I've ever seen," Rolle said. "We had to bring in a pickup truck to get all of it out of there."

He said more charges are likely after investigators finish reviewing the material, which could take weeks.

The workers found the pornography while doing repairs to the house, which was damaged Sept. 17 by the remnants of Hurricane Ivan (search), authorities said. Medvee, who lives alone, was staying with friends at the time, police said.
