A New Castle man is facing up to 13 years in prison after pleading guilty Tuesday, May 23, to sexually assaulting an 8-year-old girl in Butler in July 2021.

Mark Edward Olinger Jr., 34, pleaded guilty to a felony charge of involuntary deviate sexual intercourse with a child in a plea agreement in which he will be sentenced to serve six to 13 years in prison.

He entered his plea in a hearing before Common Pleas Court Judge Kelley Streib. She did not schedule sentencing to allow for time for Olinger to undergo a sexually violent predator evaluation under Megan’s Law.
