Fraternity wars
Sigma Rho has been accused of a number of fraternity-related violence in the University of the Philippines. Three most notable incidents involved Dennis Venturina, Niño Calinao and Cris Mendez. In December 1994, Dennis Venturina, a Sigma Rhoan, died in a riot between Scintilla Juris and Sigma Rho. On February 19, 1999, Niño Calinao, a senior journalism major was shot dead by suspected Sigma Rho members. Calinao was mistaken for a member of the rival fraternity Scintilla Juris, which clashed with Sigma Rho members in a riot a week before the killing.[1][2]. Both incidents happened inside the University of the Philippines Diliman campus.
