It’s an image even those remotely familiar with the Penn State sex-abuse scandal know about: the Lasch building locker room.

That picture took fuller form Tuesday, with former graduate assistant Mike McQueary on the stand. Prosecutors displayed several pictures of the Lasch building’s “staff and support staff locker room” for McQueary, the jury, the defense and more than 100 onlookers in a Bellefonte, Pa., courtroom during the second day of the sex-abuse trial of former Penn State assistant football coach Jerry Sandusky.
