So how do you account for the wreckage that is from the flight with serial number identification?

Haven't heard about that--which would also negate my other hypothesis that the plane crashed into a jungle-covered mountainside in Vietnam, along its flight path.

If you read the article, they found one large piece (that finding was reported on FR, BTW) which had a serial number which tied it to the missing 777. They've also found some other little pieces in Madagascar and Africa that don't have serial numbers, but would fit the airplane.

Speculation is the captain was crazy, flew up to 40,000 ft, depressurized the cabin to kill everyone, then flew south until his fuel ran out and dove into the ocean at high speed.
