Tiago Pires Luz da Silva is number 3 on a list of 11 witnesses to be interviewed by Scotland Yard in Dec 2014.
His sole statement in the PJ Files is dated 7 May 2007, where he is described as an assistant maintenance technician at the Ocean Club. It was his first job since leaving school and he had been doing it for 3 years and 4 months. He made €500 per month doing minor repairs, and he worked throughout the Ocean Club, wherever maintenance was required.
His is another statement that is extremely bland.
Is he related to José da Silva, the Ocean Club driver? Probably not, simply because da Silva is an extremely common surname in Portugal. It is impossible to be certain, as Tiago’s father’s surname is da Silva, and his mother’s maiden surname is also da Silva. There could be a relationship such as uncle or cousin. It is simply not likely.
The only item of interest in his statement is that he says he was never in apartment 5A, but that his colleagues Luis Ferro and Mário Moreira were, in order to repair a shutter and show how to work the washig machine.
Other than this Tiago da Silva appears to drop out of sight until around 9 Feb 2014, when he was identified as one of the men Scotland Yard wished to interview.

The story is about lost keys, but the Sunday Express elevated it to stolen keys. Perhaps this sound more dramatic. Perhaps it explains how the keys would fall into the hands of criminals who then knew where the keys worked.
An older maintenance worker, presumably Luis or Mário, said that in the week that Madeleine went missing, Tiago had lost the whole set of keys for block 5, and had been in tears about this.
Maria da Silva (probably no relation) was the cleaner for block 5, and in her statement she makes it plain that 10 apartments in block 5 were on the Ocean Club books.
If the story is true, it means Tiago managed to lose a total of 10 keys, an unlikely feat.
The older maintenance worker went on to say that he disliked Tiago, to the extent that when things tailed off in the Ocean Club, he decided to leave.
Luis Ferro gave his statement on 7 May 2007. In it he said that he visited apartment 5A between 10am and 11am on Tuesday 1 May 2007, to fix a shutter and to show a woman how to work the washing machine. The woman was Kate McCann, who was there alone. He said he and his colleague were only in the kitchen and the parent’s bedroom.
Mário Mareiro gave his statement on 8 May 2007. In broad terms it tells the same story that was related by Luis Ferro.
Neither of these mentioned missing keys, nor the need to get a spare key before they headed to apartment 5A to repair it on 1 May 2007. If there were lost keys, this seems to limit the timespan in which they were lost to between 11am on 1 May 2007, and Madeleine’s disappearance on 3 May 2007.
No one higher up the chain mentions missing keys for block 5, something which would obviously be very significant.
Luis and Mário both gave permission for a DNA swab on 18 Jun 2007. Mário also gave permission for a hair sample, date unknown. These would be required to eliminate them from hairs found in apartment 5A.
It seems unlikely that Scotland Yard was interviewing Tiago da Silva in respect of missing keys, though the team could have been covering all bases.
The other potential route is the Crimewatch of Oct 2013, with Tiago being matched perhaps to Smithman.
This suffers the same weakness that the programme was not widely aired in Portugal to an audience likely to recognise Tiago. One possible method would be workers at the Ocean Club who were British, and were interested in the case.
Further, if that was the basis, surely Tiago would have been interviewed as an arguido, not a witness.
Judge for yourself whether Tiago da Silva (Feb 2014) resembles the e-fit of Smithman for May 2007.
