Chilling footage has emerged of a Brazilian school shooter calmly setting his sights on victims before his accomplice hacks at their bodies, as they killed eight people.
Guilherme Taucci Monteiro, 17, walks purposefully into the foyer before he pivots round while drawing the revolver from his waistband at the school in the Suzano suburb of Sao Paulo.
He fires at the school's principal Marilena Umezu, 59 and then staff member Eliana Xavier, 38, before going on to find others to kill.
The other attacker Luiz Henrique de Castro, 25, then enters to hack at the bodies of the fallen with a machete. They killed a total of four girls, two boys and two staff members at the Professor Raul Brasil school on Wednesday morning.
