WASHINGTON TWP — A former band volunteer in the Moniteau School District is accused of having sex with a student at his home on Route 38 in the township.

State police Wednesday arrested Cody Michael Klingler, 20, who is charged with sexually assaulting the male student beginning in February when the boy was 14 years old.

Klingler allegedly confessed that he had sex with the boy on three occasions, according to court documents.

Police say the defendant also admitted he illegally accessed the boy's e-mail account to send the teen's mother e-mails that referred to her son's sexual orientation.

District Judge Lewis Stoughton arraigned Klingler on three counts each of involuntary deviate sexual intercourse, unlawful contact with a minor, statutory sexual assault and aggravated indecent assault, all felonies.

He faces an additional felony charge for unlawful use of a computer.

Klingler also is charged with three misdemeanor counts of corruption of minors and indecent assault.

He was released from the Butler County Prison early this morning after posting $10,000 bail.

The defendant, who works for an office supply store, when contacted by the Butler Eagle referred all questions to his attorney, Richard E. Goldinger.

Goldinger did not immediately return a telephone message this morning.

Police launched their investigation after Moniteau Superintendent Trudy K. Peterman on Aug. 20 forwarded two anonymous letters, purportedly from concerned parents, that had been mailed to the district.

The letters claimed Klingler was having a "secret relationship" with the 14-year-old boy, a police affidavit said. The letters also accused the defendant of "making sexual gestures and texting students."

Klingler is identified in court papers as a former volunteer band staff member at the district.

Peterman was out of her office this morning and unavailable for comment.

"(Klingler) was approved as an assistant helping with the band," Moniteau School Board President Doug Kinney said this morning. "He had direct contact with the students" in grades 9 to 12.

Kinney said he did not know when the defendant began working in the unpaid post. He would have had to undergo Act 34 clearance, which includes criminal background checks.

"Unfortunately," Kinney said, "those background checks do not predict future behavior."

The district dismissed Klingler on Aug. 12 stemming from an inappropriate text message he allegedly sent to a 15-year-old boy in the Slippery Rock School District, authorities said.

Police on Aug. 24 interviewed the Moniteau boy, who had since turned 15. The boy acknowledged having sex with Klingler at the defendant's house between February and June, when he was 14 and 15, documents said.

The boy told police he first met Klingler by way of the MySpace social networking site. Their relationship progressed, documents said, through the use of instant messaging, text messages and phone calls.

Kinney, who was not acquainted with Klingler, said he was upset upon learning of the allegations in the criminal case.

"Our district doesn't tolerate any inappropriate behavior toward any of our students," he said. "We are disappointed whenever something like this happens."
