All 10 were charged with hazing; Naquin also was charged with negligent homicide.
According toWAFB, two of the students arrested - Gott and Forde - are not now enrolled as LSU students.
The Baton Rouge Medical Examiner's report shows Gruver's blood alcohol level was.495 at the time of his death. That is more than six times the legal limit. Phi Delta Theta's national office has closed its LSU chapter since Gruver's death.
"We are committed to continuing to work with LSU, the Baton Rouge police department and the East Baton Rouge District Attorney's office to fully understand the events that led up to Max's passing so we can help prevent another tragedy such as this from ever happening again".
If convicted, hazing carries 10-30 days in jail and a mandatory expulsion from the university.
LSU President F. King Alexander said in a statement that the arrests "underscore that the ramifications of hazing can be devastating".
A witness told police that Gruver was "highly intoxicated" when members of the Phi Delta Theta fraternity left him on a couch sometime after midnight on September 14. The autopsy found Gruver inhaled vomit and other fluid into his lungs, said Clark.
On Sept. 13, pledges were called to the frat house for what was referred to as "Bible study", during which the pledges answered questions and, if they were incorrect, they had to drink. Gruver reportedly took 10 to 12 pulls. The fraternities will not be allowed to hold chapter-affiliated events during the suspension.
Gruver apparently passed out on a couch around midnight before the other pledges went home. Hall, a junior who lived at the fraternity house, is in a "deep depression" over his friend's death, his attorney said.
David Bourland says his client, Zachary Hall, of Charlotte, North Carolina, didn't break any laws or LSU codes of conduct. "He did not do anything that could have contributed to this unfortunate, tragic accident".
"This is a very serious matter involving allegations of risky behavior and a gross disregard for the health and safety of a fellow student", East Baton Rouge District Attorney Hillar C. Moore III said in a statement. Other individuals also could face charges in the case, Moore added.
Investigators are studying text messages sent and received by the fraternity members and pledges, have learned of possible videos, and have seized a duffel bag filled with beer cans, bottles of liquor, a glass smoking pipe and a "pledge test", according to search warrant requests and results.
