VENANGO CO., Pa. (EYT) — An Oil City man was recently sentenced up to 15 years behind bars in a state correctional facility for sexual assaults of two young girls.

According to court documents, 42-year-old Christopher M. Ender, of Oil City, pleaded guilty on December 22 to one count of indecent assault with a person less than 13 years of age from a July 1, 2016 incident and one count of aggravated indecent assault with a person less than 16 years of age from an incident in May of 2016.

Venango County Judge Robert Boyer sentenced Ender to five to 10 years for the July 1, 2016 crime and 19 months to five years for the May 2016 crime.

The sentences are consecutive.
