The video begins showing inmate receiving finishing touches with hand restraints in an overcrowded cell. One inmate makes gonna-slice-your-throat with sign language.
Scores of the opposing gang sign – using the middle 3 fingers to form the number 3 – are flashed in front of the camera. I believe the sign is associated with PCC – Primeiro Comando da Capital.
In Brazil, when the rival gang member gets weeded out, they are subjected to hideous acts of torture and unspeakable deaths. Whereas the killers are presumed to be from PCC, it’s possible the victim is a member of CV – Comando Vermelho – PCC’s rival.
Props to Best Gore member @seraphim-serenata for the video:
