He says that Earhart and Noonan are 'absolutely not in the photo and it's incredible that anyone could believe they are'.
'Zoom in and you can see the upper half of a white man with black hair on the far left of the group on the dock,' he said, but adds that the features, the nose, the hairline are all wrong 'and any intelligent analysis rules him out'.
That theory emerged in 1960, when CBS radio reporter Fred Goerner interviewed several witnesses who said that two white 'flyers' or 'spies' had been picked up on the island before the Second World War.
They claimed that one of them was a tall white woman with short hair, dressed like a man.
'The 1940 date is probably the most disheartening of all,' the investigator said, adding that the body shapes of 'Earhart' and 'Noonan' did not appear to be correct.
And another recognized Earhart investigator, Mike Campbell, has lashed out at what he described as 'bogus photo claims'.
Also in July, a fuzzy photograph emerged as part of the promotion for the History Channel documentary purporting to show Earhart and Noonan in Saipan, along with her plane, in 1937.
Campbell claims that the photo 'does little except discredit the truth'.Sablan, who was born in Guam and raised in San Diego, told the Daily News that he remembered telling Tun in 1971 about how he hoped to become a pilot.That triggered a memory in Tun, who recalled how two white pilots had been interned for several days on Saipan, then a Japanese hub, before they were executed.But it fits a theory proposed on the History Channel special Amelia Earhart: The Lost Evidence in July that Earthart died at the hands of the Japanese, and that her murder was covered up by the US government.Sablan's story is the latest in a number of pieces of evidence that suggest Earhart died on Saipan, rather than perishing at sea.
