Cadaver dogs led police to the makeshift grave on the 90-acre property along Route 202 in Solebury Township where several law enforcement agencies, including the Federal Bureau of Investigation, have been searching for any signs of the missing men, according to Weintraub.
One of the victims has reportedly been identified as Dean Finocchiaro, 19.
Additional human remains were found inside the grave, but have not been identified yet.
"We're going to bring each of these lost boys home to their families, one way or another", Weintraub vowed. DiNardo and Patrick both went to Holy Ghost Preparatory School in Bensalem.
DiNardo's parents own the farm.
DiNardo's social media posts showed the 20 year old retaining an avid interest in hunting, fishing and Air Jordan sneakers. However, investigators have since stated that DiNardo was arrested a second time on Wednesday, after they found he had tried to sell a vehicle belonging to Meo to a friend for $500.
In making their initial bid to unearth the whereabouts of the missing men, police said DiNardo was a Facebook friend of Jimi Tar Patrick.
It has been more than a week since the first man went missing.
The "grave", he added, was found by cadaver dogs, he said.

DiNardo also had been arrested Monday and held on $1 million bail on an unrelated gun charge before his father paid $100,000 to bail him out Tuesday.
Meo is a diabetic, yet his life-saving diabetic kit was still in the vehicle, Weintraub said. The other remains have not yet been identified.
Sturgis, 22, of Pennsburg, was last seen on Friday, 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 a midnight news conference.
Meo and Sturgis had been spotted Friday evening in the Doylestown area, confirmed as friends who went out together sometimes by Sturgis's father.
Weintraub emphasized that while authorities have focused on DiNardo, "this investigation is still wide open".
Weintraub declined to say whether investigators have any other subjects of interest, or elaborate on the relationship between DiNardo and the four men. Then, on Wednesday, authorities arrested DiNardo again, accusing him of stealing and trying to sell a 1996 Nissan Maxima that belonged Meo, according to the Bucks County District Attorney's Office.
But DiNardo was prohibited from owning such a weapon, the document alleges, as he was "known to be suffering from a mental illness" following his involuntary commitment to a mental institution.
Weintraub stated: "We've been treating this from the outset as a criminal investigation and nothing has deterred that from this point".
