A Lehighton man admitted to sexually assaulting a young girl.

Jason Ahner, 40, pleaded guilty on Friday on the county court to one count each of rape of a child and involuntary deviate sexual intercourse with a child.

He admitted having performed a sexual act on a then six-year-old girl.

State police at Lehighton charged that the incident occurred at a trailer campground. Troopers said more than one incident occurred and happened over a period of September 2009 to Oct. 11, 2009.

Assistant District Attorney Michael Greek said during one of the sexual assaults a resident of the campground observed it through a window of Ahner's trailer. The witness then notified troopers. Greek said when the victim entered the trailer, Ahner said to her, "Want to do a secret?" He then took the girl to a bedroom in the trailer and committed the act.

Ahner was then interviewed by troopers and admitted to the act.

Under a plea agreement other counts of involuntary deviate sexual intercourse, indecent assault and aggravated indecent assault were dropped.

Under the agreement Ahner faces a state prison term of six to 12 years, if the agreement is approved by President Judge Roger N. Nanovic II, who accepted the plea.

Nanovic also said the charges fall under the provisions of Megan's Law. Nanovic ordered a presentence investigation (PSI) be prepared by the adult probation office. Ahner will also have to under an evaluation by the sexual offenders board to determine if he is a violent sexual predator. If that is determined he is a sexual violent predator then he must register for life as a sexual offender.

Greek said he agreed to the plea agreement because Ahner waived his right to a preliminary hearing and agreed not to proceed to trial to save the victim from testifying.

The Commonwealth also agreed not to invoke the mandatory sentence in the case of 10 to 20 years.
