While Weintraub was careful not to directly link DiNardo to the human remains, he said he hopes DiNardo stays behind bars. Patrick's family members said Sturgis and Meo worked together and Finocchiaro was a mutual friend.
Sturgis, a good friend of Meo, was last seen.
Finocchiaro and Pennsburg were also last seen. His parents told the police that their son never traveled without it. Two seconds later, the license plate reader registered Mr. Meo's Nissan Maxima driving by. Meo's parents report him missing to police.
In addition to the cars' locations at or near the DiNardo family's properties, the police said, officers have also uncovered other clues, which came to light in court records on Wednesday.
The families of the missing have also kept a vigil throughout the week near the area searched by investigators, the Philadelphia Inquirer reported.
DiNardo is taken into custody a second time, accused of stealing Meo's auto. The keys to Meo's auto and the title to the vehicle were found "hanging up on a wall inside the garage".
Police from seven different jurisdictions, including the Federal Bureau of Investigation, had spent four days on a large swath of farmland in Solebury Township, about 30 miles north of Philadelphia, with heavy equipment and specially trained K-9s searching for evidence.
That grand jury investigation that could provide some answers in the case, including details on Cosmo DiNardo's whereabouts during the last week. DiNardo was arrested on a charge of possession of firearms by a person prohibited from possessing a firearm. The charge stems from accusations that DiNardo was caught with a shotgun and ammunition in February despite a prior mental health commitment.
No charges have been filed against anyone in connection with the discovery of the bodies on the DiNardo farm.
Police have called the 20-year-old son of the farm owners a person of interest in the case. He was released following that arrest after his father posted a bond.
Weintraub said they've found human remains in their search for four missing young Pennsylvania men and they can now identify one victim.
Cadaver dogs led authorities to the spot on the 90-acre (36-hectare) farm in Solebury Township where they discovered the remains inside a 12½-foot-deep (3.66-meter-deep) common grave.
"Obviously, it's a heartbreaking situation and we're just hoping that some miracle happens and this turns out for the best". About a dozen reporters and lawyers gathered in the chambers to watch the arraignment, during which DiNardo said "Yes, your honor" several times.
