Swapped number plate

A seized car was seen on the road with a new driver and a number plate nobody had given it. At the car pound they swear it never left. Four people and one piece of evidence: one person per row, one per column. Whoever is left alone with it in the same room is the one you're looking for.

Suspects

• Armindo, the pound officer: He keeps the seized cars, and their keys in a locker. The locker doesn't lock.
• Bruna, the car wash attendant: She washes the cars before they go to auction. One left washed and without an auction.
• Constâncio, the mechanic: He swaps parts, tyres and, people say, number plates.
• Delminda, the lady from the corner café: She can see the pound from her counter. She saw the car leave with a driver who wasn't a police officer.
