Penn State assistant Mike McQueary told a grand jury and police that he saw former Nittany Lions assistant Jerry Sandusky sexually assaulting a young boy in the showers of the team's football facility in 2002.
But he reportedly told a family friend a different account of the incident shortly after it happened.
The (Harrisburg) Patriot-News reports that McQueary told Dr. Jonathan Dranov, a family friend and a colleague of his father's, that he heard "sex sounds" and a running shower before a young boy peered around the corner of a shower stall. An adult's arm then reached around the boy's waist and pulled him out of view. Sandusky walked out of the shower moments later.
A source with knowledge of Dranov's testimony before the grand jury relayed his account to the Patriot-News. Dranov testified that he spoke to McQueary shortly after McQueary witnessed the alleged incident, and advised McQueary that because he hadn't personally witnessed an assault, he should report the incident to his superiors at Penn State but not the police.
The version differs with those from McQueary's statement to police and the summary of his testimony in the grand jury presentment. In both of those accounts, McQueary said he witnessed Sandusky sodomizing a boy of about 10 years old in the shower.
This is a significant development, as McQueary's testimony played a key role in the perjury charges against former Penn State athletic director Tim Curley and ex-vice president Gary Schultz. It also raised questions about what McQueary told former Penn State head coach Joe Paterno, who claims he was never told about a rape or molestation when McQueary came to him the day after the alleged incident.
Curley and Schultz have testified they were told about "horseplay" that McQueary said made him feel uncomfortable. McQueary says he told them graphic details about a sexual assault.
As previously reported, McQueary told a friend in an email that he stopped the alleged rape and discussed it with police, something a source familiar with the state's investigation confirmed to ESPN's Tom Rinaldi.
McQueary testified that after witnessing the alleged assault, he left the building, called his father and the next day told Paterno what he saw.
Paterno's response to the situation came under intense scrutiny after Sandusky was charged last month, and eventually led to the Paterno's firing by the school's board of trustees.
While Sandusky has many more problems to worry about, the cases against Curley and Schultz could come down to the credibility of McQueary's testimony. McQueary and Paterno both don't face criminal charges, but their responses to what they saw or what they were told have been major parts of this story.
