Prosecutors are set to present more witnesses at Jerry Sandusky's child sex abuse trial following two days of graphic testimony about alleged abuse by the former Penn State assistant football coach.
The father former Penn State assistant Mike McQueary went into the courthouse through the entrance used by witnesses Wednesday morning.
A day earlier, his son recounted hearing "slapping noises" and seeing Sandusky standing behind a boy in a Penn State shower in 2001.
Sandusky arrived a little later, helping his attorney carry boxes and files into the courthouse.
Two of Sandusky's accusers have already testified in the case, leaving six more expected to take the stand.
The identities of two of Sandusky's alleged victims remain unknown.
Sandusky faces a total of 52 criminal counts. He maintains his innocence.
