The arraignment of four former LSU students in the fatal September hazing death of 18-year-old fraternity pledge Maxwell Gruver was postponed a day until Friday due to construction issues at the downtown Baton Rouge library that shut down the adjacent state courthouse Thursday morning.

The four were indicted last month by an East Baton Rouge Parish grand jury.

Matthew Alexander Naquin, 20, of Texas, is charged with negligent homicide, a felony punishable by up to five years in prison. Sean-Paul Gott, 21, of Lafayette; Patrick Andrew Forde, 21, of Massachusetts; and Ryan Matthew Isto, of Canada, each face a misdemeanor hazing count, which carries up to 30 days in jail.

Gruver's blood alcohol level was 0.495 percent, or more than six times the legal limit to drive, his autopsy revealed. The coroner's office said his death was an accident but could be attributed to alcohol poisoning and aspiration, which means he suffocated on his own vomit.

Gruver, of Roswell, Georgia, was targeted by senior members of Phi Delta Theta in a hazing ritual they called "Bible study" that required pledges to chug 190-proof liquor when they gave wrong answers to questions about the fraternity.

Phi Delta Theta's national headquarters pulled the fraternity from LSU's campus after Gruver died.

The 19th Judicial District Courthouse, where Naquin, Gott, Forde and Isto were originally scheduled to be arraigned Thursday morning, reopened at noon Thursday. The arraignments are now set for Friday morning.
