Jeffrey Sandusky, the son of former Penn State University assistant football coach Jerry Sandusky, pleaded guilty Friday to 14 counts of child sex abuse charges.
Those counts included solicitation of statutory sexual assault and solicitation of involuntary deviate sexual intercourse.
The 41-year-old allegedly tried to solicit nude photos from a teenage girl and asked her sister to give him oral sex.
Authorities said Jeffrey Sandusky knew the girls through their mother. The crimes allegedly occurred in 2013 and 2016, but were reported last year when the girls' father turned over text messages Jeffrey Sandusky had sent.
In one of the texts, according to the affidavit, Jeffrey Sandusky told one of the teens that sending nudes to him wasn't weird "because he studied medicine."
The girl told investigators that the texts made her uncomfortable and that he kept telling her "not to show the texts to anyone," police noted.
Prosecutors allege that he sought oral sex from the other girl in 2013 when she was just 15 years old.
Centre County District Attorney Stacy Parks Miller said the plea deal ensures the "girls can move forward and experience a life with adults that deserve their trust."
Jeffrey Sandusky could spend up to eight years in prison as part of the plea deal.
Jeffrey Sandusky's plea deal comes nearly six years after his father was arrested in a child molestation case that sent shock waves through Penn State. Jerry Sandusky was found guilty on 45 counts of various sexual abuse crimes and is currently serving a 30 to 60-year prison sentence.
