Justice may have been found for Overwatch fans, particularly Brazillian players. Christiane Louise de Paula da Silva, the Brazillian voice actress for Mercy, was killed last month (via Overwatch Reddit and Twitter). The Civil Police managed to find and arrest the suspect: an economist by the name of Pedro Paulo Goncalves Vasconcellos da Costa.
