Very sad news. Any details on what happened?

Speculation only so far. Perhaps an autopsy will reveal if medical issues were a factor.

What I find most alarming is that in this time of so many electronic gadgets available why it took about 24 hours to locate the crash site. Granted it was in a very remote area but for electronic signals that should not matter.
