A wing flaperon that came ashore on Réunion in July 2015 was matched by serial number to 9M-MRO, the aircraft that left Kuala Lumpur on March 8, 2014 with 239 people aboard. Around 20 more fragments washed up around the western Indian Ocean through 2017. The main wreckage has never been located.
In 1908 Charlie McLeod found his brothers Willie and Frank on a riverbank in what is now called Deadmen Valley. Both skeletons were missing their heads. The heads were never found, and the Scottish engineer who went in with them in 1905 was never accounted for at all.
