UPDATE: 6:10 p.m. EDT — Cosmo DiNardo admitted on Friday to killing all four of the missing Pennsylvania men and revealed the locations of their bodies to the police, the Associated Press reported Friday. DiNardo was formerly a person of interest in the case.

Original story:

The man who authorities called a “person of interest” in the disappearance of four Pennsylvania men apparently exchanged text messages with his friends about the men. Shared with the Philadelphia Inquirer by an unidentified source involved in the conversation, the text messages appeared to show Cosmo DiNardo unconcerned about the missing men.

Authorities continued searching Thursday for Jimi Patrick, 19, Tom Meo, 21, Mark Sturgis, 22, and Dean Finocchiaro, 19, all of whom last week were seen for the last time in Bucks County, Pennsylvania.

“Cosmo isn’t your buddy Dean missing,” one person in the group message asked last weekend. “Aren’t you worried about buddydead [sic] dean.”

“I mean, I know the kid,” Cosmo answered. “But yeah I feel bad for his parents. He’s a pill-popping junky who had 2 duis… He prob just jumped parole Or probation.”

The group messages shared were part of a Snapchat conversation titled, “Tom WYA,” a reference to Tom Meo, one of the missing men. WYA stood for “where you at?"

“Tom where the [expletive] you at?” one message read. “Mark where the [expletive] you at? Dean aka Ryan Smith where the [expletive] you at?”

Two unidentified participants in the conversation said Ryan Smith was a pseudonym for Finocchiaro.

DiNardo, 20, was arrested Wednesday after being accused of stealing and trying to sell the car of one of the missing men. Police found a deep grave on a massive farmland property belonging to DiNardo’s parents Wednesday evening. The human remains inside were confirmed to be one of the four missing men, identified as Finocchiaro.

In another portion of the messages, DiNardo complained about people coming onto his family’s property.

“Yeah well a bunch of people went to my properties and now the cops are waiting to arrest them for trespassing,” he said.

DiNardo also said he couldn’t understand why investigators were searching the land.

“Because no reason for people tone [sic] at my place where we don’t live,” he wrote. “I have no clue bro it’s weird people keep hitting me up I have no idea what’s up.”

After unearthing Finocchiaro’s remains, authorities continued the search for the other missing three boys. Bucks County District Attorney Matthew Weintraub said Thursday the situation was a homicide, “make no mistake about it.”

“We are going to bring each and every one of these lost boys home to their families,” said Weintraub. “One way or another.”
