I do!
The Saints dumped Hyram and Joseph in this salt shed where they lay in rest for the next 80 years. Fawn Brodie attributes this action to the concern that the Gentiles would steal and defile the corpses. This seems improbable given the fact the shed was completely abandoned, unguarded, and untouched for so long. A more likely reason was the conflict among the Saints concerning selection of Smith's successor and the division of his harem. Known to Mormons as the "Succession Crisis" and called by the historian Hubert Bancroft the "Second Mormon Civil War," the fighting (also called "Blood Atonement") raged for about 2 1/2 years - until almost all of the Saints had left for Utah, or left the organization.
Joseph and Hyrum were interred in this grave in the 1920's campaign by the Saints to clean up their historical image. Joseph's only legal wife, Emma, was discovered buried under a brick pile near to the outhouse in the back yard of the Smith mansion in Nauvoo. She was dug up and laid to rest next to Joseph at the same time the new grave was completed.
