"Penn State, with its own system, protected their public image," he continued. "Media protected their jobs and ambitions. Prosecutors protected their jobs and egos. The accusers were protected and provided access to potential financial gain, free attorneys, accolades, psychologists and attention."

He wrote that he was heartbroken.

"My trust in people, systems and fairness has diminished," he said. "In my heart I know I did not do these disgusting acts. However, I didn't tell the jury. Our son changed our plans when he switched sides."

Matt Sandusky was 18 when he was adopted by the Sanduskys after spending time with them in foster care. The relationship always has been rocky, but it collapsed near the end of Sandusky's trial in June. As the prosecution's case drew to a close, Matt told investigators that Sandusky had molested him, too.

Matt Sandusky, now 33, did not testify for either side, but Jerry Sandusky insists that his adopted son's desertion and potentially damaging testimony kept him from testifying in his own defense.

The Sanduskys spared no one.

"There were so many people involved in the orchestration of this conviction (media, investigators, prosecutors, "the system," Penn State and the accusers.) It was well done. They won!" Jerry Sandusky wrote, as if a tragic court case about molested children was an epic gridiron contest.

"When I thought about how it had transpired, I wondered what they had won," he continued. "I thought of the methods, decisions and allegations. I relived the inconsistencies and dishonest testimonies." He pondered what would happen if the tables were turned.

"What would be the outcome if all the accusers and their families who were investigated?" he wrote. "I knew the answer. All their issues would surface. They would no longer be these poor, innocent people as portrayed."

Dottie Sandusky also wrote of her disappointment, saying she has lost faith in the police and the legal system. "To think that they can lie and get by with the lies. The press has been unbelievable. People who have not met us are writing untruths."

Dottie Sandusky's letter is revealing because she has stood silently by her husband in court. She testified at his trial that she never heard or saw anything strange or sexual going on in the basement of their home, where many of the victims say her husband molested them.

In her letter, she unloaded on her adopted son, Matt.

"People need to know what kind of person he is," she wrote. "We have forgiven him many times for all he has done to our family, thinking that he was changing his life, but he would always go back to his stealing and lies. He has been diagnose (sic) Bipolar, but he refuses to take his medicine."

Records from Centre County's probation department and juvenile courts tell part of the story of how Matt H., as he was known, came to the Sanduskys.

Like the boys who testified against Sandusky at the trial, Matt participated in Sandusky's youth mentoring program, The Second Mile. Jerry Sandusky was in Southern California, preparing for the Rose Bowl, when Matt was arrested in 1995. Sandusky called personally and pulled strings to make sure Matt was placed under his care and not sent to juvenile detention.

The court documents detail Matt's continuing troubles, including an aspirin overdose in March 1996 that is characterized as a suicide attempt. But he maintained that he wanted to stay in the Sandusky home, writing to the court, "I feel that they have supported me even when I have messed up. They are a loving, caring group of people. They have showed me what a family is really like."

In another instance, Sandusky called police to his house, claiming a burglar was trying to break in. It was Matt, who said he had come to the house for a power tool.

Matt Sandusky now is represented by a law firm in State College that is handling the cases of several other Sandusky molestation victims. His lawyer, Justine Andronici, did not respond Wednesday to a request for comment on the letters.

Dottie Sandusky wrote that her adopted son "has had many run-ins with the law and stolen money and items from our family. We still love him and want the best for him, but because of his actions we cannot express this to him. ..."

Karl Rominger, a lawyer for Sandusky, also did not respond to a request for comment. A spokesman for the State Attorney General's office said prosecutors "stand by" what they said Tuesday about Sandusky's victim and system bashing. Joseph McGettigan described Sandusky's behavior as "banal, self-delusional, completely untethered from reality. It was entirely-self-focused, as if he himself were the victim."
