According to the Grand Jury presentation, that's not exactly true. On Page 7, you'll see that Paterno called Curley and invited him to Paterno's home the date after Paterno heard from the graduate assistant. Paterno told Curley about he accusation (although he may have downplayed the allegations; it's unclear whether the graduate assistant told Paterno about the anal rape, but Paterno did not make such serious charges when discussing it with Curley).
On page 8, Schultz, Senior Vice President for Finance and Business, describes a meeting with Paterno and Curley in which Paterno described the allegations.
So Paterno told Shultz.
The meeting among Paterno, Curley, and Shultz occurred before Shultz met the graduate assistant according to the grand jury presentation. The meeting with the grad student was a 'subsequent meeting." Page 8.
The meeting with the grad student, Curley, and Schultz was approximately one and half weeks after Curley met with the grad student (Page 7).
That means that Schulz was either called to Paterno's house on the day that Paterno first contacted Curley, or that Paterno, Curley, and Shultz met within the next ten days.
However, it's clear from the report that Paterno met with Curley and Schultz and that Paterno told Schultz what he had heard from the graduate student.
“(although he may have downplayed the allegations; it’s unclear whether the graduate assistant told Paterno about the anal rape, but Paterno did not make such serious charges when discussing it with Curley).”
That’s the key isn’t it?
I’m finding it extremely difficult to believe that the GA did not accurately describe to JoePa exactly what he saw.
