Ex-students attack school in Brazil, 8 dead SUZANO, Brazil (AP) - Two masked men armed with guns, knives, axes and crossbows descended on a school in southern Brazil on Wednesday, killing five students and two adults before taking their own lives, authorities said. The men, identified as former students at the school in a suburb of Sao Paulo, also shot and killed the owner of a used car business nearby before launching the attack on the school, authorities said. Besides the five students, the dead included a teacher and a school administrator, said Joao Camilo Pires de Campos, the state's public secretary. Nine others were wounded in the school attack and hospitalized, he said. Authorities identified the attackers as 17-year-old Guilherme Taucci Monteiro and 25-year-old Henrique de Castro. "The big question is: what was the motivation of these former students?" de Castro said. Monteiro opened fire with a .38 caliber handgun and de Castro used a crossbow, de Campos said, adding that forensics would determine how the victims died. The attackers were also carrying Molotov cocktails, knives and axes, authorities said "In 34 years as a policeman, it's the first time I see someone use a crossbow like that," police Col. Marcelo Salles said. "It is horrendous."
