Officers responded to an off-campus home around 11:30 a.m. Monday and found a sophomore Phi Kappa Psi pledge, Matthew Ellis, 20, unresponsive, authorities said. He was declared dead approximately an hour later.
Ellis, of Humble, Texas, had attended a social event Sunday hosted by members of a university fraternity, according to Texas State President Denise M. Trauth.
It's unclear if the event was hosted by members of one fraternity or different fraternities.
An autopsy on Ellis has been ordered, but a preliminary investigation suggested alcohol was a factor in the business administration major's death.
