Two female mummies were discovered in Tomb KV21 and were believed to be a part of the 18th Dynasty. DNA was compared between the two fetuses discovered in Tutankhamun's tomb and Mummy A, and it was determined that Mummy A is the biological mother of Tutankhamun's children.
Announcing the DNA results in 2010, "The data obtained from KV21A points to this mummy as the mother of the fetuses [in Tutankhamun's tomb]. Unfortunately we are not yet able to identify her...." Only partial data was able to be recovered and a attempt to produce a sequence was not successful.
1825: The tomb was examined and determined as a "clean new tomb"
1989: The tomb was revisited and the mummies were discovered torn to pieces, jars stored next to the tomb were shattered and graffiti was found on the tomb reading "ME 1826".
