A veteran investigative journalist has been killed in the city of Caico. Francisco Gomes de Medeiros was shot five times outside his house last Monday. One line of police enquiry is focusing on reports the murder could be linked to Medeiros’ investigation of state assembly candidates running a crack-for-votes scheme in the 3 October general election. However a former prison inmate, Joao Francisco dos Santos, has been arrested he claimed to have committed the murder. This is the second high-profile media killing this month following 16 October murder of the owner of a small Sao Paulo newspaper.
