Araújo, 37, was killed by two assailants as he left a recording studio at the radio station in Timbaúba, 100 km from the state capital Recife, close to his home on 24 April 2004. The killers stole nothing from him.
Police on 27 April arrested a man suspected of the murder, Helton Jonas Gonçalves de Oliveira, aged 18. They said he had confessed to the killing after the journalist accused him in his programme, "José Carlos Entrevista" of being behind several murders.
The popular local journalist used the programme to expose the existence of murder squads and the alleged involvement of local figures in criminal cases. Head of programmes, Caetano Marinho, confirmed to Reporters Without Borders that Araújo’s programme focused on legal cases and that he had exposed murders committed by his attacker.
