Brazilian newspaper owner and journalist Nascimento was shot in the head and chest outside the doorway to his home in Rio Claro, Rio de Janeiro state, news reports said.
Police did not disclose a motive for the killing, although investigators told O Globo that the latest issue of Panorama Geral had cited alleged irregularities in the mayor's office in the neighboring town of Bananal. The paper had also criticized the management of Bananal's public services, including sewage treatment, public parks, and health clinics, according to press reports. Nascimento, who was also active in area politics, served as president of his local residents' association and had twice run for alderman.
Panorama Geral had published only four editions, according to local news reports.
