Martin Septim never died. He turned into the Avatar of Akatosh defeated Mehrunes Dagon, and then was turned to stone. His sole and his body are still trapped in the stone statue. On a side note how cool would that be if the next DLC or next elder scrolls revolved around freeing Martin Septim from the stone and restoring him to his status as Emporer.
