No, just the one in PdL since Redwood starting sniffing around there for suspects will do nicely.
You must have known this person Luz, care to enlighten us as to his background or is he an innocent by default?
I don't know that person but only from what some residents told me. That man was in deep depression for a long time. His life had not been as brilliant as he probably had wished & it started way before 2007. He had personal problems that could explain a suicide but, as far as I could gather, other possibilities haven't been ruled out. There has been no official declaration as to what happened to him.
In Portugal, because there are limitation status for all crimes (unlike the US, for instance where there's no limitation for murder), when there are no immediate clues to follow, the strategy is to hold (archive) the investigation in order to suspend the counting of time and so, if better clues come in he future there is a chance to bring justice to any crime that has happened.
