True Crime: This is the chilling story of Karabo Mokoena and Sandile Mantsoe. Karabo was an advocate for women's rights, but in April 2017 she would find herself trapped in the very evil she had been campaigning against. Sandile Mantsoe was a forex trader, and supposedly rich, but to add to his list of damning characteristics, Sandile was actually in debt by the tens of thousands. He was coined as "The Devil in disguise" by a judge in his trial.
