A former Highlands School District teacher charged last week with sexual assault against children continued to teach after leaving the district in 2022.

Sean Dicer, 53, of Brackenridge was most recently employed at Penn Christian Academy, a private school in Penn Township, Butler County.

Dicer was arrested Thursday and charged with involuntary deviate sexual intercourse with a child, unlawful contact with a minor and sexual extortion.

Investigations by Allegheny County Police do not involve any Penn Christian students at this time, Head of School Wendi Caldwell said. Nor are they connected to any school activities, she said.

Dicer, in addition to being a 19-year Highlands elementary teacher, was known to frequent district activities because of his private photography business. He was a fixture at youth and school sports events, often selling photos to families.

He became the focus of a criminal investigation on Nov. 7 after Tarentum police received a report made to the state’s child abuse hotline.

A tip was made by a 16-year-old boy claiming he had been abused several years earlier by Dicer.

Claims by a second boy were also investigated. The boys, now 16, were 11 and 12 when the alleged assaults occurred, according to a criminal complaint.

Administrators at Penn Christian confirmed that Dicer worked at the school for one year, beginning in November 2024. The facility includes students in preschool through eighth grade.

School leaders were made aware of concerns regarding Dicer on Nov. 7, Caldwell said.

“After careful review, prayerful consideration and consultation with legal counsel, the decision was made to terminate his employment effective immediately on Nov. 10th,” Caldwell said.

County Police on Monday said they’ve received information that indicates there might be more victims. They are seeking additional information from the public.

Duke George, Dicer’s attorney, said every claim brought against his client will be addressed.

Dicer is being held in the county jail. A preliminary hearing is scheduled for Dec. 17 at District Judge Carolyn Bengel’s courtroom in Brackenridge.

Caldwell declined further comment, citing it as a personnel issue and sensitive matter.

“Our priority continues to be the safety, well-being, and trust of our students, staff and families,” she said.

“We are committed to transparency within the bounds of what is legally and ethically appropriate.”
