Cosmo DiNardo was arrested after investigators found he tried to sell a missing young man’s car the day after he vanished.

“In exchange for his confession, Mr. DiNardo was promised by the district attorney that he will spare his life,” said Lang.
The confession from the 20-year-old suspect ended a macabre and fascinating probe that started with the July 5 disappearance of Jimi Taro Patrick, 19.
Victim Dean Finocchiaro, 19, was identified early Thursday after cadaver dogs sniffed out the human remains. Mark Sturgis, 22, and Thomas Meo, 21, went missing two days after Patrick, as did Finocchiaro.

Investigators gather under tents as they search a property on Wednesday in Solebury, Pa., for four missing young Pennsylvania men feared to be the victims of foul play.

Lang, speaking shortly after 5 p.m., said DiNardo directed authorities to the victims’ burial locations on the sprawling 90-acre property.
Bucks County District Attorney Mathew Weintraub had earlier canceled a 3 p.m. news conference, presumably as plea negotiations went on with the suspect and his lawyer.
“This is a homicide, make no mistake about it,” Weintraub said earlier. “We just don’t know how many.”

Cadaver dogs led investigators to the remains of 19-year-old Dean Finocchiaro, one of four young men who went missing last week.

Weintraub added cryptically that he knew “more than I’m sharing” about the ties between the suspect and the four other men.
DiNardo, 20, admitted “participation in the murders of four young men,” said Lang. The lawyer declined to say whether anyone else was involved in the killings.
There was no immediate comment from local police or prosecutors.

“It seemed almost like a horror film or something, just unraveling before our eyes,” said local resident Claire Vanderberg, 18.
DiNardo’s backstory emerged as the investigation continued: He was previously committed to a mental health facility, was repeatedly involved with area police over the last six years, and was banned from the campus at Aracadia University after a single semester.
Excavators were back at work Thursday on a sweltering July afternoon, digging in the deep trench with a tent for their only cover as they continued the grim search for human remains.

DiNardo once boasted of having someone killed over a debt

In text messages obtained by the Philadelphia Inquirer and the Daily News, DiNardo shrugged off a question from a friend about the missing Finocchiaro.
“Cosmo isn’t you buddy Dean missing?” asked one member of last weekend’s group chat.
“I mean I know the kid,” replied DiNardo. “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.”
A Snapchat photo viewed by the newspapers also showed the bearded DiNardi holding what looks like a revolver while glaring into the camera.
