Judge Cleland issued an order Friday allowing a defense motion to offer expert testimony from a psychologist who "will explain that the words, tones, requests and statements made in the letters are consistent with a person who suffers from a Histrionic Personality Disorder."
"The goal of a person suffering from this disorder in writing those letters would not necessarily be to groom or sexually consummate a relationship in a criminal manner, but rather to satisfy the needs of a psyche belabored by the needs of such a disorder," the defense lawyers wrote in their motion.
Sandusky was expected to be examined Sunday by a prosecution psychologist related to the personality disorder defense, according to a source with knowledge with the case. It was not clear if that happened.
Another person who could testify is Dottie Sandusky, the accused ex-coach's wife. While many alleged victims knew her, she is not accused of having witnessed any sexual abuse.
Lastly, there's the question of whether Sandusky himself will take the stand.
Amendola told jurors last week that Sandusky routinely "got showers with kids" after working out and that he would say so later.
Kuby, the defense lawyer, said having the former coach testify may give him his best chance at avoiding jail time.
"Just maybe he can convince one juror to hold out," the lawyer said. "A hung jury, right now, is a lot better than life without parole."
