Judge William Wenner called it "a tragic day for Penn State University."
What they're being charged with:
State prosecutors allege that the three men failed to tell police about sexual abuse allegations involving Sandusky and then tried to cover up what they knew about it.
The men say they are innocent and were not aware of the allegation against Sandusky in 2001. They say they had believed that Sandusky and the boy were engaged in nothing more than horseplay in a university locker room shower.
