They were in a fire, but there wasn't enough time for their bodies to decompose. I wonder how they got that way then? Luke must have come up at most a few hours later. Maybe their bodies were eaten by decomposers, but it's the desert-there aren't any! Or the stormtroopers could have done the blaster torture thing where they essentially shoot off your flesh using a low power setting. Ouch!
They were VAPORIZED! ;-)
