Not really. Only a few pictures of the room and books surfaced, those you can see on the decifreolivro.com and news videos. The police is currently investigating his disappearance.
I don't think so. Student Bruno Borges disappeared last Monday (3/27). His relatives called the police and broke the door to his room, discovering the whole occult/crypto content. Video/images made their way to news websites here in Brazil, and from then on theories about the content began to emerge. The website was made by people trying to decipher the books.
