An eminent historian and archaeologist who led the discovery of a mass grave of murdered Irish railroad workers in the US from nearly 200 years ago says evidence now points a second site with more bodies in it.

Archaeologists unearthed the first mass grave at the infamous ‘Duffy’s Cut’ nearly 50km west of Philadelphia in 2004. In total, 57 bodies were buried there in 1832.
