Former Penn State assistant football coach Jerry Sandusky was sentenced in October 2012 to 30-60 years in jail for 45 counts of sexually abusing 10 young boys. The Oprah Winfrey Network announced today that, Sandusky’s adopted son, Matthew, elaborated on his own experiences of abuse in an interview that will air July 17.

From OWN:

In his first television interview since Jerry’s 2012 conviction on 45 counts of child sexual abuse, Matthew reveals never-before-heard details of the sexual abuse he experienced as a child at the hands of his adopted father, and why he is choosing to speak out now. During the trial, Matthew gave a statement to local police that Jerry started sexually abusing him around the age of 10-years-old, though he was not one of the ten victims Jerry was convicted of abusing in the criminal trial. After the trial, Penn State University and a third party law firm found enough merit and credibility to award a financial settlement to 26 of Jerry’s victims, including Matthew. He shares a deeply personal account of the grooming, methodical control and manipulation he faced as a child and responds to the accusations his adoptive mother, Dottie Sandusky, made on national television accusing him of lying and stealing from the family.

Lawyers for Jerry Sandusky planned to have his client take the stand during his trial, in order to say that his accusers were lying. However, the threat of Matthew then offering public testimony of his own abuse convinced the lawyers not to let Jerry testify.

Matthew is one of six children Jerry and Dottie adopted.
