The Monmouth County Prosecutor’s Office said Friday that skeletal remains found at a Wall Township construction site were human. They also said that the bones were “of an advanced age” and that no foul play was suspected.

The bones were found on March 12 at a site located on the 1100 block of Narrumson Road where work was being done to build a foundation for a new home.

“The analysis of the remains, performed by an anthropologist with the New Jersey State Police Forensic Anthropology Unit, revealed that the bones belonged to multiple individuals. While the precise age of the remains cannot be quickly determined with a high degree of accuracy, it is strongly believed that they are of an advanced age,” officials wrote in a statement.

They said that the deaths of these individuals did not appear to be suspicious.

As News 12 New Jersey has previously reported, an 1873 map of Wall Township from the Historical Society shows the region was mostly farmland. Historians tell News 12 it was not uncommon for farmers to bury loved ones without any markers.
