A new report identifies the 28-year-old graduate assistant who tried to blow the whistle on Jerry Sandusky as current Penn State assistant coach and former PSU quarterback Mike McQueary.

Their testimony of what happened in 2002 — when now-assistant coach Mike McQueary said he witnessed Sandusky in a sex act with a boy in a shower — contradicts that of Paterno and McQueary.

In the presentment, jurors wrote that McQueary — identified in the presentment only as a 28-year-old graduate assistant — was credible but Schultz and Curley were not.

Several sources have identified that witness as McQueary.

McQueary allegedly saw Sandusky raping a boy of about 10 years old in a shower in a locker room at Penn State. He reported the incident to Joe Paterno, and then Athletic Director Tim Curley. He is, apparently, now a witness for the prosecution, and the grand jury found his testimony to be very compelling.

McQueary’s Penn State bio identifies him as a “graduate assistant coach” from 2000 to 2002.
