Three fraternal deaths in less than a week have re-examined Greek life at universities across the country.
The death occurred in the Alpha Tau Omega Liaison House, where police and medical practitioners responded to treat a member of the liaison group who, according to the police, appeared unconscious and did not breathe.
Members of the Brotherhood performed a CPR until the doctors arrived, but newcomer Samuel Martinez had died, the police said.
The National Office of the Brotherhood said the chapter is cooperating with the authorities in the investigation.
"Alpha Tau Omega mourns over a deceased member overnight," the Brotherhood said in a statement on Tuesday, adding that the counselors offered this to students "help and support."
The National Brotherhood said it was planned to send a team to the school "to work with members of the chapter and assist the university and law enforcement when needed".
A preliminary investigation revealed that Martinez's death may be related to alcohol, Pullman told the police.
Whitman County coroner will determine the official manner and cause of death, police said, adding that the investigation is still ongoing.
