What changes have taken place in your life and the lives of people around you since 2017 let alone 2007?
Nothing stays static
As long as Madeleine's case remains open and active it can be presumed there is still work being done. I believe when a police investigation runs out of options it gets shelved although kept under review; I don't think Madeleine's case is at that stage yet.
One thing I am sure of is that investigators have far more information available to them and a clearer picture than in 2007.
Nobody knows what Op Grange is doing now because they don't say. All four of them are quiet. It's unlikely in my opinion that they have added to whatever A C Rowley knew in 2017, and he clearly stated that they had relied on the first PJ investigation to have 'dealt with' the question of parental involvement.
That means that Op Grange began it's investigation at a certain point. If they chose the wrong point to begin then they may be going in completely the wrong direction. Indeed, their lack of a conclusion suggests that may well be the case.
