GA Mike McQueary catches Sandusky in a locker room shower at 9:30 at nite raping a 10 year old boy. He then leaves (without confronting the man) and calls his own father. His father has him come over to his house (he lives in SC). The next day father and son (the witness) go to see Paterno. Joepa then reports it to the AD. Etc, etc...
Thanks for making this a bit clearer.
