After complaining of stomach pain, the student was rushed to a hospital where he was diagnosed and underwent emergency appendectomy when he died on the operating table. Philippine President Ramon Magsaysay formed an investigation committee which concluded that while medico-legal findings failed to show that the hazing "contributed to Albert's death", the initiation ritual severely weakened his physical condition prior to the appendectomy. The committee further recommended the expulsion of four Upsilon officers, the suspension of dozens of its members and neophytes, and a censure of several UP deans, directors, and faculty members for their failure to discharge their duties. Albert's death was the first recorded death attributed to hazing in the Philippines, and the only known death of an Upsilon Sigma Phi neophyte. On September 20, 1969, a member of Upsilon Sigma Phiwas beaten to death by members of the Beta Sigma fraternity. He was the first recorded fatality in a fraternity "rumble" in the University of the Philippines, prompting UP president Salvador P. Lopez to issue new rules and regulations regarding student misconduct as well as issuing a suspension for both Upsilon Sigma Phi and Beta Sigma. On July 4, 2014, UP Diliman chancellor Michael Tan identified Upsilon Sigma Phi as the fraternity involved in the hazing of a 17-year-old student who sustained multiple injuries that required hospitalization. On June 18, 2015, Quezon City police arrested five members of Upsilon Sigma Phi after allegedly mauling three rival fraternity members
