Jerry Sandusky's Son Details His Father's Abuse To Oprah

Matthew Sandusky gives his first interview after his father's arrest.

Former Penn State assistant football coach Jerry Sandusky was sent to prison for child molestation back in 2012, but it seems the story of his abuse is far from fully told.

His adopted son, Matthew Sandusky, recently sat down with Oprah for a special that will air on OWN on July 17 and detailed how he had been abused by the former assistant coach.

Matthew Sandusky, who testified against his adopted father during his trial after originally speaking on his behalf, was 10 when the abuse started -- and thought he was the only one suffering at the hands of the elder Sandusky. His adopted father was convicted on 45 criminal counts for sexual abuse of 10 boys over 15 years and was sentenced to 30 to 60 years in prison.

"At bedtime, his ritual began," Matthew tells Oprah in a clip from the upcoming show, which will reveal "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."
