Nadia Kheider, of the Antiquities Ministry, says Sunday the skeletons belong to a woman in her early 20s, a man in his late 30s and a man in his early 40s. Chief researcher Zeinab Hasheesh says one of the skulls has a cavity indicating a “surgical intervention.” Mostafa Waziri, head of the Supreme Council of Antiquities, says researchers found gold inside some of the bones. The 2,000-year-old sarcophagus, which was filled with red fluid, created a stir on social media. The ministry says the red fluid was sewage water.
