A young man identified only as Victim 6 will be in a Pennsylvania courtroom Tuesday to "set the record straight" and testify against former Penn State coach Jerry Sandusky, his lawyer told ABC News.
Howard Janet said his client -- one of 10 young men Sandusky is accused of molesting in a 15-year period -- would testify in Tuesday's preliminary hearing despite "mixed emotions."
"It's very difficult. It's trying, but it's something that needs to be done to serve justice," Janet said. "It's an opportunity for him to set the record straight in response to charges by Sandusky and his lawyer that he hasn't been telling the truth and these other young men haven't been telling the truth."
Last month, Sandusky's lawyer said that Victim 1 was retaliating against a tough mentor and had exaggerated his story after getting attention from prosecutors. The lawyer also said that Victim 2, who Sandusky is accused of having raped in a Penn State shower, claimed he was never molested.
Victim 6 was allegedly bear-hugged by Sandusky as they showered together at Penn State in 1998 when the accuser was 11. He is now 24.
The boy's mother filed a complaint at the time, but a police investigation ended with no charges filed. Sandusky was recorded by police, however, telling the boy's mother that the shower was a mistake and "I wish I were dead."
Sandusky Lawyer: No Plea Talks
Janet would not comment when ABC News asked him about the 1998 investigation.
"I will let this young man speak for himself with respect to that at the grand jury tomorrow," he said. "It will be evident that charges were warranted [then] and continue to be warranted."
Today, Sandusky's lawyer Joe Amendola told The Associated Press there had been no plea negotiations before the hearing.
"We plan to proceed with Jerry's hearing and Jerry is looking forward to the opportunity to face his accusers," he said.
Sandusky, 67, is charged with 50 counts relating to child molestation. On Tuesday, he is scheduled to appear in court for the first time to face his accusers. The hearing is expected to last several days.
Last week, sources close to the case told ABC News that eight victims would testify against Sandusky.
On Wednesday, Sandusky was arrested as two new accusers emerged, bringing the number of alleged sex abuse victims to 10. It was not clear whether the most recent accusers would attend Tuesday's hearing.
Last week, Sandusky's wife Dottie Sandusky said that she was "shocked and dismayed" by allegations that her husband had sexually abused boys in their home and that she'd ignored their cries for help.
In an earlier interview, Amendola told ABC News that he faced an "uphill climb."
"We're fighting a system," he said. "We're fighting a three-year investigation in which the attorney general's office has accumulated what they believe to be a lot of evidence against Jerry Sandusky."
