A secret grave in Philadelphia that may hold 57 Irish workers has gone unnoticed for 183 years.
But now, the bodies – along with evidence showing they were murdered – will soon come to light.
The workers arrived in Philadelphia from their home country in 1832 and were victims of anti-Catholic and anti-cholera hate and hysteria, according to CBS 3.
The grave was uncovered 13 years ago when researcher Bill Watson and his brother, Frank Watson, found old and confidential railroad files in a deceased relative’s attic.
“183 years ago, the railroad buried some its secrets here.” Bill Watson told the news outlet. “Things they didn’t want anyone to find out about.”
The remains of six of the workers were found between 2009 to 2011, but for the last four years, the search has been on hold while they tried to get legal clearance to excavate the area.
The hidden secrets are known as “Duffy’s Cat,” according to CBS 3, named after the contractor responsible for bringing the workers to the site.
Samples of the soil are currently being gathered and will be analyzed at the University of Pennsylvania.
“For 13 years, we ve been trying to figure a way to get these guys out of here, and now I think we’ve got it,” said Bill, who added that if the bodies are found, they will be identified and returned to their home country of Ireland.
