The pool seen from the drone

The council sent a drone over the protected area. The drone filmed a pool, a slide, eight people pretending not to be there and no evidence at all. Some clues in this case come as riddles. If one stumps you, a hint will solve it. Eight people and one piece of evidence, one per row and one per column. Almost nothing is said directly: you'll have to cross everything.

Suspects

• Arlindo, the drone operator: He filmed it all in high definition. In high definition the pool looks even bigger.
• Bernardina, the owner of the villa: She says the pool is a water reservoir for wildfires. A reservoir with a slide.
• Cecílio, the neighbour who complained: He complained to the council. He has an identical pool, but his has had a licence since last week.
• Dora, the family's lawyer: She says the drone violated the pool's privacy.
• Eurico, the gardener: He waters the garden with water from the pool. He says that's why the pool is a reservoir.
• Felícia, the protected area inspector: She brought the drone report. The report says the pool doesn't exist, because it isn't on the map.
• Gilberto, the lifeguard: He was hired to watch over the reservoir. He says he's never saved anyone, but the reservoir is deep.
• Hilda, the reporter from the local paper: She published the drone footage. The paper has never had so many visits.
