According to court records, Vance Heyer entered his plea Monday.
Deputy Lancaster County Attorney Bruce Prenda said that Heyer was 21 and vice president of the FarmHouse Fraternity when he purchased bottles of vodka for an off-campus party on Sept. 4, 2014. Eighteen-year-old Clayton Real was found dead the next morning in his room at the fraternity house. Affidavits in the case say Real died of acute alcohol intoxication.
Twenty-year-old Thomas Trueblood, 23-year-old Ross Reynolds and 23-year-old Cory Foland pleaded no contest to procuring alcohol to a minor in February.
All four men are scheduled to be sentenced April 25.
