The third victim is identified as 19-year-old Howard Hillhouse Stone from Martinsville, Virginia. He was a sophomore majoring in Political Science at the University of Mississippi.
Twenty-year-old Jordan Williams from Atlanta and 19-year-old William Townsend from Clarksdale were also killed in the blaze. It started around 4:30 Friday morning at the Alpha Tau Omega fraternity house on campus.
Autopsy results show the three died from smoke inhalation. Investigators say questions remain about the exact cause.
"One of the key thins is that we have a very big house with a very small room that we're look at. We hope to have a finding in a short order," says Special Agent Mark Chate with the Bureau for Alcohol, Tobacco and Firearms.
Twenty-two students and the housemother were inside the house when it began. The survivors of the blaze are now being housed in other campus housing.
