Bucks County District Attorney Matthew Weintraub said that the remains were located in a makeshift grave that was nearly 13-feet deep on the property.
The bodies of Dean Finocchiaro, 19, Tom Meo, 21, Jimi Taro Patrick, 19, and Mark Sturgis, 22, have all bean identified, Weintraub said.
A source familiar with the case told the Inquirer and Daily News late Thursday that it was DiNardo who led investigators to Kratz and the bodies of the four young men who have been missing since earlier this month.
Cosmo DiNardo, who is being held on $5 million cash bail, has been described as a person of interest in the investigation.
Meo's 1996 Nissan Maxima was discovered on the same farm as Finocchiaro's body and the other human remains. DiNardo said he picked up Patrick in Newtown and drove him to a DiNardo family property at 6071 Lower York Road in Solebury Township, where he shot and killed him, then buried his body using a backhoe to dig the 6-foot-deep grave. And Dean Finocchiaro, 18, of Middletown Township, Bucks County, was also last seen alive Friday. "I talked to him just about every day", said neighbor Bill Hale. Kratz is charged for three of the murders, while DiNardo faces charges for all four. He's since been charged alongside DiNardo for taking part in three of the killings.
Dinardo allegedly poured gasoline into the tank and lit it, the complaint says. They shot and killed Finocchiaro and then placed him in a metal tank that he referred to as the pig roaster, Dinardo said, according to the criminal complaint.
The search has focused on the extensive property - owned by Dinardo's parents, Antonio and Sandra, according to prosecutors - in Solebury Township.
At least some of the missing men are friends, but it's unclear how well they knew DiNardo, if at all. He said that body would not have been found at the DiNardo farm if the plea bargain had not been struck. The remains of Patrick were recovered from a separate location on the farm. Local media reports say that Dinardo and Patrick attended the same preparatory school in Bensalem, Pa., while Dinardo and Finocchiaro had both posted on a Facebook page for buying and selling all-terrain vehicles. DiNardo drove a backhoe to the crime scene and buried him, the documents state.
It was the discovery of Meo's auto on a DiNardo family property a half-mile from the farm that led to DiNardo's re-arrest.
The back-to-back arrests bought investigators time as they scoured the farm and other spots across the county for clues to the men's disappearance, Weintraub said.
Also on July 7, Dinardo said he met Meo (fifth photo) and Sturgis (sixth photo) at a church parking lot in Peddlers Village, a short distance west of the Dinardo property on Route 202 in Lahaska, the court records say. An attorney for the family, Fortunato Perri Jr., said in a statement that they were not connected to the alleged homicides. DiNardo also told investigators where the bodies are.
DiNardo is "known to be suffering from mental illness".
DiNardo's lawyer admitted Thursday his client's role in the four slayings.
Earlier this year, authorities charged DiNardo with possessing a firearm despite an involuntary mental health commitment.
