Kelly Aldinger, 49, a substitute teacher at Easton High School, was charged Tuesday morning with having sex with a student on May 6 in the Easton Cemetery
A married 49-year-old substitute teacher at Easton Area High School was interrupted by police while she was having sex with a 17-year-old boy in the Easton Cemetery this month, police said.

Kelly Aldinger, formerly of Easton, was charged with institutional sexual assault Tuesday morning before District Judge Daniel Corpora. He ordered Aldinger held on $50,000 bail pending a hearing scheduled for May 31.

Corpora said he would consider lowering Aldinger's bail after she is interviewed by pretrial services at the prison. Her contract as a temporary substitute at the high school was terminated, her attorney, Josh Fulmer, said following Aldinger's court appearance.

Her employer, Source4Teachers, released a statement that she has been "indefinitely suspended" from working in any districts that contract with the company.

Superintendent John Rinehart said the district will conduct an internal investigation.

"The circumstances are obviously very disturbing and upsetting to all of us because we have to be able to trust these individuals who work with us to use their best moral and ethical judgment when working with children," he said.

The district started using Source4Teachers in 2013.

According to court records, city police officer Joseph Arredondo was on patrol at 1:06 p.m. May 6 when he spotted a vehicle parked in the cemetery at 401 N. Seventh St. The officer could see a woman and a male were in the vehicle having sex, police said.

As an officer questioned her at the cemetery, Aldinger said she was 49 and a substitute teacher at the high school. The boy, 17, said he is a junior at the school, according to court records.

Aldinger said she met the boy several years ago when she was a substitute teacher at Easton Middle School.

Both the boy and Aldinger told police they had been involved in a sexual relationship since the fall, when he was 16, according to court records.

Police have been investigating Aldinger's relationship with the boy since May 6 and say they have found no other victims.

Aldinger surrendered to police Tuesday morning at the district court in Easton and was handcuffed in the hallway before her arraignment. During the arraignment, Aldinger told Corpora that within the past week she had moved from the home she shared with her husband and children on Maywood Street in Easton to her parents' home on the 600 block of Williams Street in Pen Argyl.

Aldinger's parents were in court Tuesday morning. Aldinger did not comment as she was led to a police car in the court parking lot. Cemetery Superintendent Jeff Mutchler said he knew of an incident a few weeks ago, but wasn't aware of the charges. "We rely on the Easton Police Department to help us at the cemetery," Mutchler said. "They come in, they do drive-throughs."

He said couples, some of them prostitutes, teens and drug users, try to take advantage of the out-of-the-way nature of the historic cemetery.

"It's a park-like setting," Mutchler said. "Because it's secluded, quiet, we do have people come in here and they're disrespecting the family of the people that are buried here."

Mutchler said the cemetery is installing surveillance cameras that he hopes will deter people from causing trouble in the cemetery.
