A separate investigation by ex-FBI director Louis Freeh, who was hired by Penn State's board of trustees to investigate the university's handling of the Sandusky allegations, is due later this summer.
Hall of Fame coach Joe Paterno was fired for a failure of leadership for not going to the police after McQueary told him about that incident. The scandal also caused the departure of university president Graham Spanier.
Philadelphia-based lawyer Fortunato Perri Jr., who followed the trial, said the jury's dismissal of the charge involving the 2001 shower incident could help Curley and Schultz' defense.
"You've now had a jury kind of preview your case with respect to the credibility of McQueary, and they didn't believe him," Perri said. "Who knows if the next jury would believe him or not believe him?"
But the administrators' attorneys would probably be precluded from introducing the acquittal evidence at the separate trial, Perri said.
Sandusky's sentencing is expected to occur in about three months; an exact date hasn't been set. Because of the severity of the charges and mandatory minimum sentences, he faces an effective life sentence.
Until his next court date, Sandusky is one of 272 inmates at the Centre County Correctional Facility, seven miles from the Penn State campus. He was kept under watch overnight and is allowed access to some personal items including a prayer book, and can get visits from family, friends and attorneys.
Rominger said he planned to visit him on Sunday.
