Reports said Palma was shot dead by two unidentified men on a motorcycle outside his home in Miguel Pereira, a suburb to the south of Rio de Janeiro, and died at the scene. He was the owner of the local weekly newspaper Panorama Regional, which was circulated in several nearby municipalities. The paper had frequently alleged corruption in the local government and a friend of Palma's told the daily O Globo that the publisher had received threats but had not taken them seriously.
