Tiago Gomes da Rocha carried out an estimated 39 murders in his native Brazil between 2011 and 2014. He would ride up to one of his victims on a motorbike, shoot them, and speed off. They were like gangland killings, except that his targets were people he'd never met. Most were either homeless or members of the homosexual community. In the end, he was convicted for 11 of his alleged 39 murders, and was only given a 25-year sentence for his crimes.
