Since the discovery of the tomb and until 2015, it was unknown who was buried here.
Excavations in 2003 and in 2014 made it very likely that the structure was once a royal tomb.
At the latter date, during the excavation directed by Josef W. Wegner of the University of Pennsylvania, a fragment of a funerary tomb stela bearing a relief naming a king Sobek[hotep] was found inside the enclosure, on the eastern side of the complex, close to where a small funerary chapel might once have existed.

While in early press reports, published just after the discovery, king Sobekhotep I was named as the possible owner of the tomb, further analyses now indicate that this might belong to Sobekhotep IV instead.

Indeed, not only do the fragments of wooden sarcophagus uncovered indicate a late Middle Kingdom date for the construction of S10, but its size means that its owner would have had to reign for long enough to complete it.
This only leaves Sobekhotep III, IV, and VI as possibilities, with Sobekhotep IV being the most likely as he enjoyed the longest reign of these three kings.
In addition, Sobekhotep IV is the only one of these kings for whom it is known with certainty that he undertook other works in Abydos.
As a corollary, the nearby and slightly larger tomb S9 most likely belongs to Sobekhotep IV's predecessor and brother, Neferhotep I.
