That is totally irrelevant. It has been discounted so was of no value then.
The PJ only discounted it because it wasn't RM. To quote from the documentary The Truth of the Lie (English translation)
Olegário de Sousa
Chief PJ Inspector
18.31 – A male individual, aged 33 and a resident in the area of the events has been made an arguido. He was questioned as such, and no evidence has been collected that could justify his detention and further judicial questioning.
19.11 – The journalist suspected him, but we didn’t follow what the journalist said. We followed the analysis of the facts. The facts were analysed, what actually had happened, and we followed a testimony, a testimony that had to be weakened in order to advance the abduction theory. Jane Tanner’s testimony. Because otherwise, the abduction theory died right there. The major foundation for the abduction was what that witness had seen: a man carrying a child, walking into the direction of Robert Murat’s house.
