PITTSBURGH — A former South Butler Middle School teacher was sentenced in federal court to 2 years imprisonment, followed by 10 years of supervised release on his conviction of possession of material depicting the sexual exploitation of a minor.

Senior United States District Judge Donetta W. Ambrose on Thursday imposed the sentence on Jason B. Nolan, 37, of Gibsonia.

Nolan was indicted in December 2012 by a federal grand jury in Pittsburgh on one count of possession of material depicting the sexual exploitation of a minor.

According to information presented to the court, Nolan used a laptop computer taken from the school’s library to acquire and possess images of child pornography. Nolan also used the laptop to communicate online with minors, including a female he believed to be 12 years of age, with whom he spoke of meeting to have sex and to whom he sent naked, sexual photographs of himself, taken in his classroom after school hours.

In August, the state Professional Standards and Practices Commission suspended Nolan. The school district website no longer lists him as a teacher.
