A teenage girl told investigators how she and a teacher kissed and had intimate sexual contact inside Warwick High School over a two-year period, according to police documents filed today.

Todd Nicholas Sheerer, 29, of 3471 Coronet Ave., Lancaster, the Warwick High School band director, was charged late Thursday with corruption of minors by two area police departments for his alleged relationship with a 17-year-old girl.

Today, Lititz police filed an additional charge of corruption of minors involving the same girl. Manheim Borough and Penn Township police were expected to file additional charges later today, sources said.

According to the affidavit filed today by Lititz Borough Police Detective John Schofield, the teenager told investigators she had been involved in a relationship with Sheerer beginning in January 2006.

The girl told police that she and Sheerer met in the band room and the backstage wardrobe changing room of Warwick High School, kissed and had intimate sexual contact "numerous times" during a two-year period, according to the court documents.

The teenager also told police that Sheerer would tell her or write her notes suggesting she "wear certain clothing to school" so she could expose herself to him "inside the band room when the two were alone," according to the affidavit.

The alleged inappropriate relationship came to the attention of authorities on the afternoon of Jan. 18, according to court documents, when a Manheim Township policeman, responding to an anonymous call, found the couple in a restaurant parking lot.

Sheerer and the young women were in the back seat of the car parked behind Friendly's restaurant on Oregon Pike, according to the affidavit.

According to the affidavit, Sheerer's jeans were unzipped and he told the officer the young woman was 19 years old. Police said they later determined the female's real age.

The following Wednesday, according to court documents, the 17-year-old girl, accompanied by her mother, met with with police detectives from several jurisdictions.

During those discussions, according to the affidavits, the teenager told detectives of various meetings she had with the band director.

The girl told detectives that during the past year they would meet in a vehicle and perform various sex acts on one another on "numerous occasions and various locations in Lancaster County."

The couple met in parking lots of a garage, restaurant, quarry, hotel and a housing development, according to a Warwick Township Police affidavit.

Manheim Borough police are charging that the couple met more than two dozen times in a parking lot near Stiegel and Oak streets, where they would undress and have inappropriate sexual contact.

Sheerer is the director of the high school marching band, symphonic band and jazz ensemble, as well as the middle school concert and jazz bands. He also teaches music at both schools.

School district spokeswoman Lori Zimmerman said today that the matter is a personnel issue and a police matter, declining to comment on the situation.

Last week, Zimmerman said a substitute teacher was filling in for Sheerer.

Defense attorney Merrill Spahn declined comment today, saying he had not had an opportunity to read all of the police charges.

Sheerer has been credited with reviving the marching band program, winning a state band title in 2006 and 2007 in the Cavalcade of Bands.

His wife assisted him as the Warwick High School Band's color-guard instructor.
