ZELIENOPLE — The family of a juvenile who was allegedly sexually assaulted while staying at a Butler County-based mental health treatment facility has filed a civil lawsuit in Allegheny County.

According to the 30-page lawsuit filed Wednesday against Glade Run Lutheran Services and its chief executive officer, Charles T. Lockwood, the unidentified 15-year-old was sexually abused between March and July 2015 while staying at the facility.

The boy, who suffers symptoms of post-traumatic stress disorder, attention-deficit/hyperactivity disorder and other developmental disabilities, was placed in the facility in December 2014 when he was 13 years old.

He was sexually assaulted by multiple people at the facility while Glade Run Corp. staff members knew, the lawsuit alleges.

“When John Doe attempted to speak out about what was happening to him, his pleas for help were met with anger, hostility, violence and public embarrassment by the Glade Run staff,” according to the lawsuit.

The lawsuit, filed by Michael J. Pisanchyn Jr. of Pisanchyn Law Firm in Pittsburgh, claimed the juvenile “suffered serious physical and psychological abuse over an extended period of time” because of Glade Run’s negligence.

The Pennsylvania Department of Human Services revoked the license of the Glade Run facility in Zelienople last year amid child sexual abuse allegations.
