Where is the REAL body of the Swedish poet Joe Hill?

''Onward Christian soldiers, rip and tear and smite! Let the gentle Jesus bless your dynamite.'' This was penned by Joe Hill, who, was involved as a witness of a rather messy Swedish love affair and crooked business activities, entangled around the Swedish Forien Office. Hill now became the target for retaliation. He then fled Sweden, coming to USA around l901, being around 20 years old. Exceptional gifted in seeing through hypocrisies and lies, Hill, became a troublesome person for the authorities, not the least for his nasty writings. The Swedish Foreign Office got wind of his being and Hill became a marked person. Possibly partly framed by them, he was accused for the killing of a policeman, and executed by bullet after a mock trial. But where is his REAL body seeing he was never cremated, a rare method at that time. Does anyone know?
