Djedfre died early and it wasn’t completed. According to Quirke, who bases his pharaoh list on surviving monuments rather than Manetho, Djedfre’s young son succeeded him, but in short order was replaced by Khafre.
AFAIK the youngster’s burial is unknown, as is the cause of death. Since the son and successor of Menkaure and grandson of Khafre is listed in Manetho as the first pharaoh of the 5th dynasty, and his burial monument is a mastaba (a reversion to a prior practice) and nowhere near Giza, there may have been a dynastic struggle, other intrigue, and/or some kind of black swan (invasion, uprising, plague).
Treachery...................
I remember looking at the site on Google Earth a few years back and it looked like you could see the remains of a surrounding wall and other site complex structures. It just struck me as odd that all that would be built before the completion of the pyramid itself - assuming that stuff was really related to the pyramid.
Djedfre looks more like an Egyptian name. That “Jed Fry” had me wondering. Wasn’t he one of the Beverly Hillbillies? Wait, that was Jed Clampett.
