Texas State University suspended all fraternity and sorority activities on Tuesday, a day after the death of a Phi Kappa Psi pledge — the latest in a string of similar episodes on campuses across the country.

Denise M. Trauth, the university’s president, said in a statement that Greek organizations would be “prohibited from holding new-member events, chapter meetings, social functions and philanthropic activities until a thorough review of the Greek Affairs system is completed.”

Joanne Smith, the vice president for student affairs, will oversee the review and ultimately “propose recommendations for reinstating fraternity and sorority chapters that demonstrate a commitment to the core values of Texas State and the ideals established by their respective national organizations,” Dr. Trauth said.

The Phi Kappa Psi pledge, Matthew Ellis, attended a fraternity event Sunday night and was found unresponsive in an off-campus apartment complex the next morning. The police in San Marcos, Tex., where the university is, said at a news conference on Tuesday that alcohol may have been a factor, but that the cause of death would not be confirmed until toxicology results are available, which could take up to two months.
