Those gruesome details emerged as DiNardo and Kratz were charged with multiple counts of conspiracy, homicide and abuse of a corpse as the investigation into their slayings shifted focus to Kratz's role in the case.
DiNardo said the men were killed one at a time and at least three were shot, with their bodies burned and buried on the farm, the AP reported.
Bucks County District Attorney Matthew Weintraub told reporters Friday that DiNardo's confession led investigators to uncover Patrick's body about a half mile away from the common grave "on top of a mountain".
Jimi Taro Patrick, 19, of Newtown Township, was the first to go missing last Wednesday.
Dinardo then drove the backhoe over Meo and "basically crushes him", Kratz told police, according to the complaint. After that, they buried the bodies in two separate graves. All four, including Dean Finocchiaro, 19, of Middletown Township, Mark Sturgis, 22, of Pennsburg, Montgomery County and Tom Meo, 21, of Plumstead Township, will be remembered.
Neighbors on the cul-de-sac where Dinardo lives in Bensalem described him as a good kid who went out of his way to help others, such as volunteering to shovel them out during snowstorms and refusing payment. Finocchiaro had come to buy drugs; Kratz and Dinardo had planned to rob him.
Court documents note the Dinardo then wrapped Finocciaro's body in a blue tarp, put the body in metal tank he called "the pig roaster" and set Finocciaro's body on fire. Dinardo told investigators that he had a marijuana "deal" set up with Meo, according to the affidavit. DiNardo, 20, reportedly implicated a co-conspirator during talks with prosecutors. However, Kratz told police that Dinardo was the one who shot Finocchiaro. DiNardo said he had run out of ammunition, so he ran over Meo with the backhoe. A news conference with the Bucks County district attorney is scheduled for 2 p.m. eastern time.
Weintraub said the two weapons used in the four homicides were also recovered.
"I'm not really sure", Weintraub said when asked to explain the suspects' motives.
Weintraub confirmed a plea deal exists, but did not give details. Kratz, of Northeast Philadelphia, also faces with 17 other counts of the same charges.
Court records show Kratz was previously arrested on two separate burglary charges in Philadelphia for thefts in June and December of a year ago where he reportedly stole $1,000 in tools and $450 worth of jewelry. His disappearance was reported to the authorities the next day. Metal detectors were later being used to search the property, according to KYW News Radio. But as soon as the victims exited DiNardo's vehicle, the suspect shot Meo, who reportedly fell to the ground screaming.
The multi-agency investigation into centered on a farmland property in Solebury Township owned by Antonio and Sandra DiNardo.
The person with knowledge of the confession said one of the men was killed July 5 and the other three were killed July 7.
"I don't understand the science behind it, but those dogs could smell these poor boys 12½ feet below the ground", Weintraub said.
At this point, court documents say, Meo was screaming in pain and Dinardo climbed into a backhoe and ran over the injured Meo, killing him.
The police authorities then ordered the research on all the properties of the torque, in order to find clues that may lead to the four men that it was now no news since five days. He declined to elaborate on what they involved, but said the suspect was well known to police.
