ZELIENOPLE — No criminal charges will be filed against Glade Run Lutheran Services after an investigation into child-on-child sexual abuse at one of its facilities, Butler County District Attorney Rich Goldinger said Wednesday afternoon.

“We can’t establish that any of the adults actually knew what was going on,” Goldinger said. “There’s a concern about being able to prove that they abused their duty of care of these children.”

Glade Run is a residential treatment facility that houses nearly 100 youths ages 8 to 21.

Its 56-bed facility was stripped of its license by the state Department of Human Services after it was found that seven youths between the ages os 8 and 13, mostly male, engaged in sexual activity with each other while personnel were not adequately doing their duties.

Glade Run is going through the appeals process with the state seeking to get its license back. The campus has three other facilities that will remain open pending the appeal decision.

“There’s no evidence at this point that any of it was not consensual,” Goldinger said. “We don’t believe we can prove it in court. It doesn’t look like there’s going to be anything coming this.”

The Zelienople Police Department had been investigating the matter for nearly four months.
