In 1993, eight homeless children were murdered outside the Candelaria church in Rio De Janeiro.

The murders caused international outrage and put a spotlight on corrupt policing in Brazil.

Matt Pintus has been speaking to Yvonne Bezerra de Mello, a social worker and teacher who had worked with the Candelaria children for years before the massacre.
