UPDATE: 'Leads are incredibly hot' in search for 4 missing men

The search for four young men is now part of a criminal investigation, according to the Bucks County district attorney.

District Attorney Matthew W. Weintraub said Monday morning the focus of the search remains on a property in Solebury Township. The men went missing last week.

Weintraub, speaking in Solebury Township, asked for the community's cooperation.

"Please, do not take the law into your own hands," he said.

"A number of search warrants" are expected to be served later in the day, district attorney's office spokesman Larry King said.

Investigators are casting a "pretty wide net" and while they don't know how the case will turn out, Weintraub said he was confident they'll "get to the bottom" of it.

He asked "for patience and prayers." Investigators are focusing on the whereabouts of the four men and hope "to ascertain whether or not they can bring them home safely."

It is "all hands on deck" until the investigation is complete, he said.

The case is spread out across social media with families making pleas for information on the missing men and several police departments working on the probe. It's not clear why the four would be on the multi-acre property about 30 miles south of Easton, King said.

Weintraub identified the missing men as Mark Sturgis, 22, of Pennsburg, Montgomery County; Tom Meo, 21, of Plumstead Township, Bucks County; Dean Finocchiaro, 18, of Middletown, Bucks County, and Jimi Tar Patrick, 19 of Newtown Township, Bucks County.

The district attorney disclosed the names to dispel rumors, he said.

The investigation, run by district attorney's office detectives, involves the FBI, several police departments and the Central Bucks Crime Team, Weintraub said.

Aquetong Road road was closed between Meeting House Road and Route 202, Solebury police said.

Patrick has not been seen or heard from since 6 p.m. Wednesday, Newtown police said. He has not communicated with friends or shown up for work, "which is not normal for Jimi," police said.

Meo and Surgis have been missing since Friday, Weintraub said. They were last seen near Routes 202 and 263, a Facebook post said. Meo is a diabetic, another post said.

Sturgis' vehicle -- a 2003 Nisan Altima with Maryland tags -- was reportedly found in the Peddlers' Village parking lot in Solebury, according to the Intelligencer of Doylestown. That's not far from where they were last seen. Another vehicle connected to one of the men was also located in that area, the newspaper said.

Middletown Township police said Finocchiaro, who lives in the Hampton Bridge section of the township, was last seen about 6:30 p.m. Friday getting into a vehicle on Hampton Drive.

Other than the friendship reported on Facebook between Sturgis and Meo, authorities are still trying to connect the four men, King said. There is a Finocchiaro who wishes a man the Intelligencer identified as Sturgis' father a happy birthday in 2014 on Facebook, but Dean Finocchiaro isn't listed among that person's friends.

Weibtraub said authorities have been told the four men were friends, but investigators are still trying to confirm that.

Patrick is 5 feet 10 inches tall, weighs 150 pounds and was last seen wearing gray shorts and a multi-colored polo shirt, Newtown police said.

Finocchiaro is 5 feet 9 inches tall,weighs 150 pounds and has brown hair and hazel eyes, Middletown police said.

Sturgis is 6 feet 1 inches tall, weighs 180 pounds, has black hair and beard and brown eyes, his family said on Facebook.

Anyone with information on the case is asked to call 215-297-8201.

Another update from Weintraub is expected at 3:30 p.m. CrimeWatch Bucks County will also provide updates as needed, he said.
