So I guess that rules out the two fuselage half's reported earlier.
There was an sms circulated around Indonesia last night around 9pm that the wreck (broken fuselage) had been found next to a waterfall at 3,000ft , the waterfall turns out to be a landslide , the height 5,200ft and the 'fuselage' is the tail cone and another component I can't identify higher up.
In failing light and in bad weather it would be easy to imagine what was reported.
