CHATTANOOGA, TN (WRCB) -- There are new details in the case of a Grundy County man facing federal charges of making child pornography.

He's accused of sexually exploiting at least 15 young boys.

Rollins appeared in U.S. District Court Monday morning, where more details came out.

A detective told the court, evidence collected from Rollins' home dates back to 1989, with two of his victims being a father and his son.

Channel 3 was there as a U.S. Marshal escorted 44-year-old Jimmy Rollins to stand before a federal judge. 

A grand jury indicted him on child pornography production charges, after investigators say they found more than 300,000 photos and videos in his Palmer home. He's accused of sexually exploiting at least 15 young boys from Grundy and surrounding counties. 

In court, Winchester Police Detective Chris Layne testified while searching Rollins' home, investigators discovered videos of Rollins performing sexual acts with the boys.

Layne also says two of his victims are a father and son. The father was abused decades ago and Rollins recently preyed on his 16-year-old son.

A cousin of Rollins spoke to Channel 3, but didn't want her face shown.

"We didn't know anything. We were all very shocked about the pictures and all that, which we haven't seen the pictures. We don't know what's going on," Rollins' cousin says.

She says she wants to apologize to the victim's families, but she also says she wants to see what other evidence comes out.

The detective testified he hasn't interviewed the 16-year-old victim yet.

"I don't see how you can take someone to court if you haven't even talked to the victim," she says.

But, Chief Magistrate Judge William Carter said the evidence was strong enough to keep Rollins behind bars.

All nine of the federal indictments are linked to the nude photos of just the one sixteen-year-old boy.

Rollins pleaded not guilty to the charges last week. Rollins is also facing two rape charges in state court based on the sexual acts in some of the videos.

It also came out in court that Rollins was convicted of rape in Grundy County in the early 90s.
