18yo pregnant girl burned alive in brazil
The girl was found burned and almost nude. She was 18 years old and two months pregnant. The case was solved in a couple of days.
She was invited to a party, which turned out to be a trap lured in an ambush by a friend (fellow callgirl) who was jealous and therefore had "sentenced" her to death. She was invite, and after some drinking and maybe drugs she was unconscious. The "friend" tortured her in the prescence of several other people, expecting that they would keep their mouth shut - which they didn't.
The killers, a 22yo man and two girls (14yo and 17yo) took the poor girl, still alive but unconscious, to a desolate place and set her on fire.
