Here's a link to the front page: Thai Tabloid Thai rath Leaked David Carradine Death Photo
They don't say it's a fake, here's their explanation of the dark skin (No mention of why the dark hair though.)
"Discoloration of the skin on the lower extremities indicates he had been dead for hours before being found, according to people familiar with the situation."
The family's response:

I would have to agree that the published photo was a fake.
I enjoyed watching him as Kwai Chang Caine in the Kung Fu series.
Sincerely,
