Jerry Sandusky's adopted son Matt is speaking about his two abusive fathers and says sexual abuse is the "single worst health epidemic that children face."

Matt Sandusky told more than 200 people Friday at the Philadelphia Children's Alliance's conference on child abuse intervention that the public must work harder to end child sexual abuse.

He spoke about his biological father burning his toes and his adoptive father subjecting him to sexual abuse.

Matt Sandusky met Jerry Sandusky through the former Penn State assistant football coach's youth charity. He says the abuse progressed over time.

Matt Sandusky came forward with his allegations against Jerry Sandusky during a 2012 trial in which eight men testified that his adoptive father abused them.

Jerry Sandusky was convicted and is serving a 30- to 60-year prison sentence.
