on the east side of the mastaba, the son of kaninisut, who was also called kaninisut, had a modest tomb for himself added to his father's mastaba. the upper building is 8.8 m long and 3.5 m wide. through the east side of this addition, one could access its cult chamber, which also had two false doors in the west wall. the underground chamber for the sarcophagus was found largely empty and was probably robbed in ancient times. despite this, some grave goods were found lying around, including fine alabaster vessels, small copper tools and four clay jars which had held the organs of the mummy.
