He also set himself on fire, police said. He later died after succumbing to burn injuries in a local hospital.
Janauba's mayor has declared a seven-day mourning period.
Although the motive behind this atrocious attack still remains unclear, police superintendent, Renato Nunes, told Hoje em Dia newspaper that the guard had had mental health problems since 2014 and often sought the prosecutor's office to denounce his own mother. "I want to express my solidarity with families", wrote Brazilian president Michel Temer on Twitter.
Temer said he understood "this must be an extremely painful loss" for the parents, as he, too, is the father of a school-age child.
