Nobody saw a thing, as usual

The police guard the door, the National Guard patrols inside and, even so, nobody saw or heard anything. Hardly any direct clues. You'll need to work by elimination all the way.

Suspects

• Artur, the regional spokesman: He speaks into microphones as if every sentence were his last before resigning.
• Benilde, the head of the party cheer squad: She runs the party's cheer squad with the discipline of someone who has managed worse.
• Cipriano, the 'friend of the house': Nobody knows why he's always around, but he's always friendly.
• Dulce, the protocol florist: She looks after the flowers for official events and, now and then, something else.
• Ermelinda, the police officer on the door: She was at the door all night. She says the door didn't see anything either.
• Firmino, the National Guard on patrol: He did four rounds. He swears everything was in place every time, except him.
• Glória, the night shift cleaner: She cleaned the whole floor before six. She just didn't clean away the suspicions.
• Henrique, the spokesman's driver: He stayed in the car listening to the match. The car was outside the office.
