A Pottstown woman accused of having sex with an underage teenager in a parked car in November waived her preliminary hearing in a Montgomery County court Tuesday.

Iris Gibney, 42, faces charges of corruption of minors, disseminating obscene materials to a minor and trespassing in a motor vehicle. She is free on $50,000 bail.

Gibney waived the hearing in Gilbertsville District Court and will next face arraignment in February in Montgomery County Common Pleas Court.

Gibney and the teenager allegedly were caught naked inside a vehicle at Hollenbach Park by a police officer.

The officer had spotted two vehicles in the Upper Pottsgrove park after it had closed on Nov. 15, at about 8:30 p.m., officials have said.

Investigators determined that Gibney and the teenager met while attending a function at Pottsgrove High School.

The pair then communicated via Twitter and Gibney later sent several nude photographs of herself to the teen, according to prosecutors.
