The Malaysian police appear to have buried their heads in the sand on this case. There is simply next to no chance Nora would have headed out into the dead of night and wondered off into deep jungle. It appears she had no rations or anything on her feet.
Its a classic example of nations putting their vested tourist interests above conducting a thorough investigation. While there is no evidence at the moment to suggest she has been abducted, there is no evidence to say that she wasn't.
It is time to wind down the search effort in the local jungle now and look at the alternatives.
What was the mark on the window and who left it?
Where Nora's footprints end does another start?, Tire tracks?, another different set of footprints?
With the summer rains and high temperatures vital evidence could be lost to the elements if the Malaysian police continue to pursue this dead-end path.
