Later that day, LSU President F. King Alexander said police are investigating allegations of hazing, and alcohol is "part of the allegations". Hazing is risky, irresponsible and unacceptable. Alexander also said that hazing is not acceptable and will not be tolerated on LSU's campus and as a result all Greek life activities are suspended.
"We mourn the loss, and the possible impact that he may have had on our region and the world", he said. An autopsy is planned for Friday, September 15.
The LSU chapter of the Phi Delta Theta released a statement on Gruver's death via Twitter.
"We're committed to investigating this situation thoroughly", Bob Biggs, the chief executive at Phi Delta Theta, said.
Few details about the investigation were available early Friday morning, but authorities said they are looking into allegations that alcohol may have been a factor.
Gruver, who graduated from Blessed Trinity Catholic School, had not yet pledged with the fraternity.
Louisiana State University (LSU) officials are investigating the death of an 18-year-old student, as reported by WBRZ. "The chapter and any individuals who are found to have violated our policies will be held accountable". Recruitment at fraternities and sororities there ended last month. "Our deepest sympathies and prayers go to his family and his friends", Alexander added. Officials say the fraternity, which is on the university campus, did not have any registered events with the school on Wednesday.
The suspension of LSU's Greek activities comes as campuses nationwide are taking a tough stance on alcohol abuse and hazing following high-profile incidents like the alcohol-related hazing death of Tim Piazza, 19, at Penn State's now-closed Beta Theta Pi house.
