BUCKS COUNTY, Pa. – Multiple sets of human remains were unearthed from a 12-foot-deep mass grave on an isolated Pennsylvania farm early Thursday as authorities continued digging for the bodies of four young men who disappeared last week.

Dean Finocchiaro, 19, was one of the bodies identified, reported Fox News. He disappeared last week along with Mark Sturgis, 22, Tom Meo, 21, and Jimi Tar Patrick, 19.

Bucks County District Attorney Matthew Weintraub said he could not identify the other remains at this time.

The investigation seems focused on Cosmo DiNardo, 20, as the grisly discovery was made on his father’s farm. He was arrested Wednesday for reportedly trying to sell Meo’s car for $500 on July 9. This was one day after Meo was last seen. That 1996 Nissan Maxima was also found on the family’s farm, which is about 30 miles north of Philadelphia.

DiNardo was being held on $5 million bail. That appears to indicate the authorities believe he is somehow responsible for the bodies in the mass grave.

At this point in the investigation it is unclear how the four men knew DiNardo, if at all. He was originally released Tuesday evening to his parents’ home in Bensalem. Although he was released from custody, FBI agents sifted through mounds of dirt from a deep pit they dug on the farm about 20 miles away. Police cadets combed the vast cornfields nearby.

Even though it was unclear if DiNardo knew the four missing men, they knew one another. Patrick’s family members said Sturgis and Meo worked together and Finocchiaro was a mutual friend.

Weintraub said police would “continue digging and searching that property until we’re satisfied that they are not there.”

“This is just really, really rough on everybody involved because of the heat, the magnitude, the scope—and the stakes are incredibly high—life and death,” he said.

DiNardo was originally arrested Monday on a charge that had earlier been dismissed, accused of possessing a shotgun despite a previous mental health commitment.

Weintraub sought a high bail for DiNardo on the gun charge because he now considers him a flight risk. The father, Antonio DiNardo, posted $100,000 Tuesday to bring his son home after the initial arrest.
