The Piazzas were recognized for their anti-hazing advocacy since their son's death in February 2017 from injuries he sustained after a night of drinking and hazing at the Beta Theta Pi fraternity house.
Joseph Ems, 22, of Philadelphia, is scheduled to enter a guilty plea on Aug. 8 before Centre County Judge Brian Marshall, according to court dockets.
Centre County Judge Brian Marshall sentenced former Beta Theta Pi brother Ryan Burke to 27 months of probation and three months of house arrest.
The trial will begin on Feb. 6 and is expected to last until March 6.
The eight defendants are among 24 still facing charges in connection with the February 2017 death of Penn State fraternity pledge Timothy Piazza, who sustained fatal injuries after falling during an alcohol-fueled initiation event prosecutors have described as hazing.
Tim Bream, the former live-in adviser for Beta Theta Pi fraternity, will not face a perjury charge for his testimony at a preliminary hearing in the case.
