NORRISTOWN, Pa. (CBS) - A former vice principal in the North Penn School District has admitted in Montgomery County Court that he texted sexually explicit messages to a pair of 13-year-old boys who were students at the school.

Charles Hurst pleaded guilty today to two counts of corruption of minors and one count of possession of cocaine. The 37-year-old former vice principal at Pennbrook Middle School, in North Wales, admitted that he had inappropriate conversations with the students about sexual acts.

Montgomery County prosecutor Samantha Cauffman plans to seek jail time for the Lansdale man when he is sentenced later this year.

“He used his position of authority as a vice principal and educator to manipulate these boys into thinking it was okay for them to report about sexual activity and for him to give them money,” Cauffman told KYW Newsradio this morning. ”It was totally inappropriate, and it was hurtful to those boys.”

Defense attorney Greg Nester says his client admitted his guilt in an effort to spare the families a trial. Nester plans to ask for probation.

Hurst was hired by Lower Moreland for a similar position before the charges became public. He remains suspended without pay.
