The closer it is to the apartment, the more 'iffy' it is. It seems highly unlikely that a stranger is going to bury a body or evidence right next to the scene of the crime.
That leaves eitehr she woke, wandered, fell into open road works, wasn't spotted and the road works were closed up, or someone staying in the apartments. All speculation on my part obviously.
No-one actually knows exactly who occupied these apartments.
For some reason the elementary police work necessary to ascertain that was omitted by the initial investigation.
NSY did request access to information about apartment owners and occupancy. That request was denied along with many others.
I agree, Cariad, the people staying in the apartments should have been interviewed in 2007.
Extraordinary that they were not.
Extraordinary that NSY have been blocked from finding out who they were. They considered it important enough to request the necessary permission, pity no-one thought it important enough to grant their request.
