UPDATE: Teacher, student had sex for months, cops say

A woman working as a substitute teacher at Easton Area High School was charged Tuesday morning with institutional sexual assault on a 17-year-old male student after they were caught having sex in Easton Cemetery, city police report.

Kelly Aldinger, 49, of the Easton area, was found by a police officer at 1:06 p.m. May 6 having sex with the 17-year-old student in Easton Cemetery off North Seventh Street, Lt. Matthew Gerould said in a news release.

Aldinger is employed by Source 4 Teachers and placed at Easton High as a substitute teacher, Gerould said. The 17-year-old was at one point taught by Aldinger, Gerould said.

The sexual relationship between Aldinger and the student began in 2015, though they initially met when the teen was middle school, according to court documents. The teen is now a junior in high school.

Source 4 Teachers spokesman Owen Murphy said Aldinger was suspended indefinitely from teaching anywhere.

"The safety of students is always Source 4 Teachers' top priority," Murphy said in a prepared statement. "We are cooperating with the district and law enforcement to provide any necessary information or assistance they need to perform their investigation and resolve this matter."

Murphy said all substitute teachers most submit state and federal criminal background checks and a child abuse background check before they're hired by his company.

The school district was contacted and assisted in the investigation, Gerould said.

The investigation is ongoing concerning other possible incidents involving the teacher and male student, Gerould said.

Aldinger arrived in court around 9 a.m. for arraignment before District Judge Daniel Corpora, Gerould said.
