First, that wing section cannot possibly be from a King Air 200.

Second, the referenced King Air 200 is currently on the tarmac in Las Vegas: https://flightaware.com/live/flight/N17VA

That number is a coincidence.

I think that's a red herring. The code "BB-670" coincidentally matches the construction number of a particular Beechcraft airplane built in 1980, tail number N17VA. But the wreckage cannot be from that plane, because it's still intact, and was flying as recently as earlier today! https://flightaware.com/live/flight/N17VA
