No comment

At the press conference, the most used word was 'investigating'. The second was 'no comment'. Meanwhile, a grenade from the evidence table moved. The clues no longer hand you everything on a plate.

Suspects

• Anabela, the army spokeswoman: She read a three-page statement that said nothing. She said it very well.
• Bráulio, the photographer: He photographed everyone. In the only shot he needed, he was changing lenses.
• Carolina, the minister's adviser: She came to insist the minister knew nothing. Nobody had asked yet.
• Dionísio, the sound technician: He switched on the press conference microphones. He also switched them off when he saw fit.
