Weintraub implored the public to continue to come forward with tips, saying that investigators are particularly interested in any information that connects the four missing men to each other, to DiNardo, or to the Solebury Township property.
Multiple local law enforcement agencies have been joined by the Federal Bureau of Investigation in their search for the men, all said to have known one another prior to their disappearances, according to investigators.
"The leads are incredibly hot, they're fruitful". The men, all between the ages of 18 and 22, went missing over the course of two days in Bucks County, a suburb of Philadelphia. Meo and Sturgis were reported missing Sunday. "And we don't know as of yet what exactly will be revealed".
Sturgis was last seen leaving his house Friday night to visit Meo, Sturgis' father told NBC 10.
Sturgis' father said that Meo and his son went missing last week after being seen in the Solebury area, according to WPVI.
Of note, Fox Philadelphia reports that missing man, Dean Finocchiaro had been arrested multiple times in the past. PHOTO: Cosmo DiNardo DiNardo was released on bail on an unrelated gun charge Tuesday; he has not been charged in connection with the missing men.

Police allege DiNardo was not permitted to possess a firearm because he'd previously been involuntarily committed to a hospital for mental illness.
Weintraub said the court was aware of DiNardo's status when bail was set on Monday. He said authorities "hope and pray" they will all be found alive. Investigators also searched a property in Bensalem that the DiNardo family owns, CBS Philly reports.
"I can't even begin to imagine", Potash, Sturgis' father, told the Inquirer. He has three sisters and one brother.
Family members kept vigil Tuesday at the search site, prosecutors said.
Bucks County authorities are expected to update the search at an 11 a.m. news conference.
Concern first arose last Wednesday with the disappearance of 19-year-old Jimi Tar Patrick of Newtown Township. A friend of Finocchiaro's, Wil Snyder, told the County Times, "He's a good guy, a good friend".
The FBI, Pennsylvania State Police and local law enforcement agencies are searching for 22-year-old Mark Sturgis, 21-year-old Tom Meo, 19-year-old Dean Finocchiaro, and 19-year-old Jimi Tar Patrick.
