The man is called Manuel Luis and has been missing since Friday at lunchtime in Santana.
Manuel Luís is deaf and was last seen in Achada do Teixeira, between 1:30 and 2:00 pm. He was shirtless because of the intense heat he felt and he had a green bag in his hand.
The niece explained that the man has a slight cognitive deficit and had an outbreak yesterday morning, so he should be lost and disoriented.
The family asks those who meet Manuel Luis to contact the authorities or the niece Elsa Caires, through the number 963 722 403.
