Dos Santos' management team described the shooting as "cowardly and senseless". It left his hometown in mourning, with many fellow surfers leaving the beach and displaying cards and banners in protest at the violence. "Mourning in paradise," said one poster put up in the centre of the beach neighbourhood of Guarda do Embau. Military and civil police in Santa Catarina have launched inquiries.
Studies in 2000 found that there were more than 32,500 deaths from firearms with estimates of the total legal and illegal guns in Brazil ranging from 16.8 million to 17.6 million.
Gustavo Oliveira, a former surf judge and photographer, said dos Santos had recently been concerned by the increase in drug use at the picturesque beach close to where he lived. "Ricardo had campaigned a lot through the media, asking for people to help Guarda become a peaceful place again," Oliveira said. "He was a friend of everybody ... he was always the same, always smiling."
