Paterno apparently told Athletic Director Tim Curley, but no one notified police. Curley and Gary Schultz, Penn State's senior vice president for finance and business, are now facing felony charges of perjury and failing to report the allegations to authorities.

Prosecutors said later that the McQueary incident took place about a year earlier than was originally alleged, causing defense attorneys for Curley and Schultz to argue that one of the charges should now be dropped. Both of them have pleaded not guilty, and their attorneys have said that prosecutors "charged this case before (they) knew the facts."

The prosecution is preparing witnesses for their testimony next week, several sources close to the case said Tuesday. Victim 4 is expected to testify first, with Victim 1, who started the investigation by coming forward in 2008 and alleging years of abuse, to follow, the sources said.

McQueary and his father were told to be in town and ready to testify next Wednesday or Thursday, one of the sources said.

Cleland told members of the jury pool that jurors in the case will not be sequestered, saying he will trust them not to read newspapers or follow the case online.

As jury selection in the case began Tuesday, Penn State released a statement, saying, "The acts that Jerry Sandusky is accused of committing are horrible and if proven true, deserve punishment."

The university said it would not comment on the specifics of the legal case but said it hopes that the trial "provides answers we are all seeking" and that "the legal process will start to bring closure to the alleged victims and families whose lives have been irrevocably impacted and that they can begin the healing process."

Several of Sandusky's alleged victims, including Victim 4, asked a judge to protect their identities at trial. However, Cleland ruled Monday that the alleged victims' identities may not be concealed during the trial, although they will be protected through the jury selection process. CNN generally does not identify alleged victims of sexual assault.

In interviews after his arrest, Sandusky acknowledged showering and "horsing around" with boys but denied being sexually attracted to them.
