One of the most valuable artifacts looted was a headless stone statue of the Sumerian king Entemena of Lagash. The Entemena statue, "estimated to be 4,400 years old, is the first significant artifact returned all the way from the United States and by far the most important piece found outside Iraq. American officials declined to discuss how they recovered the statue." The statue of the king, located in the center of the museum's second-floor Sumerian Hall, weighs hundreds of pounds, making it the heaviest piece stolen from the museum – the looters "probably rolled or slid it down marble stairs to remove it, smashing the steps and damaging other artifacts."
