RIO DE JANEIRO - Marcelo Arruda was wearing a black T-shirt bearing the face of his hero, presidential election front-runner Luiz Inácio Lula da Silva, the day he was killed.
On July 9, prosecutors say, Jorge José da Rocha Guaranho, drove to Arruda's Lula-themed birthday party, blasting the song lauding President Jair Bolsonaro so loud that the guests could hear the chorus: "The myth has come and Brazil has woken up."
