Police in two townships have charged a Warwick High School teacher with corruption of minors for allegedly engaging in a yearlong sexual relationship with one of his students.

Todd Sheerer, 3471 Coronet Ave., a music teacher and the school's band director, was charged Friday by police in Warwick and Manheim townships with engaging in "repeated sexual acts" with a female student, now 17, since January 2007.

According to one of the arrest affidavits, Sheerer, 29, would pick up the student "at pre-determined locations" and engage in sex acts with her inside his vehicle up to four or five times a week "at various locations surrounding Lititz."

Sources said police in three other communities are expected to file similar charges against Sheerer in connection with the alleged sexual relationship.

The girl's name was not released because she is a minor.

Merrill Spahn, Sheerer's attorney, said he could not comment on the allegations because he was in court Friday and did not have a chance to review the charges.

Warwick School District also declined to comment on the case or discuss the status of Sheerer's employment.

"All personnel have the right of due process," Superintendent John George said in a prepared statement. "The Warwick School District is compelled to honor those rights. Therefore, no additional comments will be made until the appropriate time."

Since Monday, Sheerer's classes have been taught by a substitute teacher.

Manheim Township police began their investigation after an anonymous caller notified police shortly before 4 p.m. Jan. 18 that two people were "engaged in sexual acts" in a sport-utility vehicle in the parking lot of Friendly's Restaurant & Ice Cream, in the 1500 block of Oregon Pike, according to an affidavit.

Officer Michael Kuntz knocked on the window of the Chevrolet Blazer and Sheerer got out of the back seat with his pants unzipped, the affidavit says. He told Kuntz he was a Warwick teacher and that the female in the back seat with him was 19, according to an affidavit.

Police interviewed the girl Monday and said they learned that several similar sex acts had occurred in other locations, according to the affidavit. Manheim Borough police then became involved in the investigation.

During interviews with police Wednesday, the girl said her relationship with Sheerer began in January 2007, when she was 16, and proceeded from kissing to fondling and sexual acts, the affidavit states.

The encounters "would occur initially one or two times per week and progressed to four or five times a week," according to an affidavit.

The girl told police Sheerer would take her to the parking lots of businesses, including a sports bar, a quarry, a hotel and an auto repair shop and other locations for sexual encounters, an affidavit says.

Officials in Manheim and Lititz boroughs and Penn Township said they expect to file charges against Sheerer for sexual acts that allegedly occurred in their jurisdictions.

As of Friday, no additional charges had been filed.

District spokeswoman Lori Zimmerman said Warwick adheres to state Department of Education policy on employee conduct, which prohibits teachers from engaging in sexual relationships with students.

In an e-mail sent Tuesday to parents of Warwick band members, George said "school psychologists have been made available to students to address their concerns and questions" as a result of the "unusual circumstances" in the district.

A middle school/high school band concert scheduled for Jan. 20 that was canceled in the wake of the investigation has been rescheduled for Feb. 24, the e-mail said. All band performances for the remainder of the 2007-08 school year will be held as scheduled.

Sheerer joined the Warwick faculty in 2003 and was credited with reinvigorating the school's marching band, which won a first-place trophy in the Cavalcade of Bands competitions in both 2006 and 2007.

He also is director of the high school symphonic and jazz bands and the middle school concert and jazz bands.

Sheerer is the second Warwick staff member in recent years to be charged in connection with alleged sexual contact with a Warwick student.

Former girls' basketball and softball coach Troy R. May was sentenced in 2005 to 8½ to 30 years in prison after pleading guilty to charges stemming from his relationship with a 15-year-old basketball player in 2003.
