Lets hope they have interviewed both of the parents to get an accurate description of the crime scene as discovered at about 10pm - because they were the first two witnesses to see it.
Those SY interviews would be their first statements ever to be transcribed in english without risk of translation errors (their only earlier statements, in May and Sept 2007, were transcribed in portuguese language only)
SY don't need to interview them yet when they have a copy of their book of truth
1485 "What do you mean the change in the blinds in the window''
Reply "Well you know it was pointed out, the window was open, the blind's not, you know, err down it's open, you know so
those things you know I was made aware of but err as I say I couldn't tell you exactly how far down the blind was or how much the window was open.' (DP)
DP didn't see an open window when he entered with the McCanns because he would have said so - OMG the window was open! He was a first witness so why didn't he see it? He was present with Kate and Gerry.
