Weintraub would not answer questions on why the DiNardo property is the main search site, and stressed that Cosmo DiNardo does not face any charges related to the men's disappearance.
DiNardo is being held on $1 million bail because he is considered a flight risk, Weintraub said.
Pennsylvania officials announced a person of interest on Tuesday as search crews focused on a vast farm owned by the man's parents.
Amid that search, police arrested Cosmo DiNardo, 20, whose address is listed as the Bensalem home, on a felony weapons charge that was refiled from February.
A man, related to the owners of the rural property now being searched, was taken into custody on an unrelated charge on Monday.
The fourth person to vanish was Dean Finocchiaro, 18, who was last seen in Middletown Township around 6:30 p.m. on Friday. Finocchiaro was last seen getting into the vehicle of a man who is not missing on July 7, reports the Bucks County Times.
"We will continue our investigation", Weintraub added.
Weintraub declined to comment on whether firearms have been recovered as part of the investigation, or on whether cell phone pings had been used or if they had led investigators to the DiNardo property in Solebury.
Sources tell United States media that a ping from a mobile phone belonging to one of the men led investigators to the farmland property.

The Coastguard helicopter was sent to the scene, along with Dover and Ramsgate RNLI Lifeboats, in case evacuation was required. An investigation into the collision, which occurred in the midst of moderate winds and calm seas, is underway.
When questioned if he thought that DiNardo could have done "this" alone, Weintraub said, "I don't even know what the this is that we're talking about yet". DiNardo was arrested on a charge of possession of fire.
The family of DiNardo, 20, of Bensalem, owns both Solebury properties that have been searched thus far. Sturgis and Meo worked together, while Finocchiaro was a mutual friend.
Weintraub earlier characterized the investigation into the whereabouts of the men as a "marathon, not a sprint".
The charge was later dismissed, but on June 21 an assistant district attorney asked the police department to reinstate it. DiNardo was arrested at a residence belonging to his family in Bensalem, one of several locations now being searched by authorities Monday. He also said that based on information that he "can't share", foul play was likely involved in the disappearance of the young men.
Foul play is suspected in their disappearances, Bucks County District Attorney Matt Weintraub said.
The search for the missing men has utilized cross-country law enforcement resources, according to Weintraub. "Everybody just wants to find all four of the men that are missing", Albrecht said.
When asked whether he thought the missing men were alive, the district attorney replied, "I hope and I pray that would be the best outcome".
Sturgis was last seen leaving his home on Walt Road in Pennsburg, around 6 p.m. Friday to visit his friend, Meo, in Doylestown, Sturgis' father told NBC10. On Tuesday, Mr. DiNardo's lawyer, Michael Parlow, was not immediately available to answer a telephone message.
