13yr old gang leader and his crew murdered for making threats towards an older gang (graphic video and photo)

A young boy and his fellow gang members were murdered in a gruesome manner after they recorded a video threatening an older gang in Brazil.
In videos shared online, a group of young boys with their faces covered are seen making threats, one after the other. They were later caught by the older gang members who then tortured them then blew their heads out.

The bodies of the young boys were then left on the street with their brains scattered all over the floor. The older group went on to share videos of them torturing the 13-year-old leader of the gang before killing him and the rest of his crew. A video of their corpse was also shared.
The video of the 13-year-old gang leader being tortured is really pathetic because the boy looks so innocent and still has the face of a child.
Here is a video of them making the threats. Here is one of the young gang leader being tortured. And here is a grisly video of the aftermath.
