Workers excavate coffins from a construction site in the Old City neighborhood, Thursday, March 9, 2017, in Philadelphia. Crews working on an apartment building in Philadelphia's historic district got a shock last month when their backhoes started hitting coffins and unearthing fully intact human remains. The site was supposed to be a former burial ground from 1707, and all remains were supposedly exhumed in the 1800s and moved to a different cemetery. (AP Photo/Matt Slocum)
