Construction workers were working hard into the night when they heard their equipment hit something hard and loud. When inspecting the noise closer, they thought they had found something straight out of a horror movie: The mummified remains of a woman’s body. Still dressed in a nightgown and thick stockings, construction workers assumed it was the scene of a gruesome crime. But that wasn’t quite the case. Based on the PBS documentary, “The Woman in the Iron Coffin,” forensic archaeologists uncovered the truth behind the woman unearthed in Queens, New York, who she was, and how she got there.
