An Olney man pleaded guilty Thursday to raping an 8-year-old Olney girl who was found dead in 2016. However, prosecutors dismissed a murder charge against him as part of a plea agreement. 54 year-old Glenn Ramey pleaded guilty to a charge of predatory criminal sexual assault. He also had been charged with murder in connection with the death of Sabrina Stauffenberg, who had last been seen on November 23rd in 2016 as she waited on her porch for a church bus while talking on the phone with her grandmother. Stauffenberg was found dead later that night behind a building on the south side of Olney. Ramey was arrested and charged with first-degree murder and predatory criminal sexual assault days later. Ramey took the plea deal Thursday. He is scheduled to be sentenced March 22nd in Richland County Circuit Court. Predatory criminal sexual assault carries a sentence of six to 60 years in prison.
