7 p.m.: WPVI-TV Philadelphia reports that Cosmo DiNardo, 20, of Bensalem, was taken into custody on Monday and charged with a firearms possession offense from February. His family owns both Solebury properties that have been searched thus far.
It was not yet known if DiNardo is suspected of having any involvement in the disappearance of the four men.
Bucks County DA Matthew Weintraub said Monday that investigators are making progress in the search for four young men from Bucks and Mongomery who disappeared last week. Authorities are continuing the search at a farm off Route 202 near Upper Mountain Road in Solebury Township, and sources say that effort could continue for days.
Weintraub confirmed at a press briefing that officials believe foul play was involved in the young men’s disappearance.
“We’re going to solve this,” Weintraub said, noting that at least five municipal police departments, the Bucks County Detectives, Pennsylvania State Police and the FBI are involved in the investigation.
“We are making great progress, but there’s so much more work to do,” he added, describing the investigation as an “all hands on deck” effort.
Although there are indications that some or all of the men knew one another, investigators are working to confirm that information and the extent of any connections, Weintraub said.
Witnesses at the scene Monday observed a backhoe in operation, and said that some family members of the missing were present.
Law enforcement officers from multiple jurisdictions had spent Sunday searching a large section of land off Aquetong Road in Solebury.
One of the missing men that is part of the investigation – Dean Finocchiaro, 18 — was last seen Friday evening around 6:30 p.m. as he entered a vehicle on Hampton Drive in the Langhorne section of Middletown. Since he was last seen, Finocchiaro has not been heard from or spotted, police said.
Missing Newtown Township resident Jimi Tar Patrick, 19, is also connected to Monday’s search. Township police said he was last seen last Wednesday at 6 p.m. and has had no contact with family or friends. He also did not show up for work.
Also missing are Tom Meo, 21, of Plumstead, and Mark Sturgis, 22, of Pennsburg, both of whom also disappeared last week.
A car belonging to one of the boys was found in a Peddler’s Village parking lot, sources say.
