The confession comes as officials identified some of the discovered remains as those of 19-year-old Dean Finocchiaro, while the search for the remains of 19-year-old Jimi Patrick, 22-year-old Mark Sturgis and 21-year-old Tom Meo continued. A source familiar with DiNardo's confession said that the bodies of Thomas C. Meo, 21, of Plumstead; Mark R. Sturgis, 22, of Pennsburg; and Jimi Taro Patrick, 19, of Newtown, also buried on the property. Wednesday, authorities arrested 20 year old Cosmo Dinardo on charges he tried to sell one of the missing men's cars a day after he was last seen. Dinardo then shot Finocchiaro when he was laying on the ground, according to the affidavit.
More human remains were still in the grave and Weintraub said recovery efforts by the Federal Bureau of Investigation, state police, five local police departments and some 40 police cadets would continue on Thursday.
"Cosmo DiNardo has been charged with the murder of Mr. Finocchiaro, Mr. Meo, Mr. Sturgis and Mr. Patrick". DiNardo's parents own the Aquetong Road property.
Officials say Meo's auto was found at one of his family's properties north of Philadelphia, and still had Meo's life-saving diabetic medicine inside. Investigators said that as the three left a barn area of the property, Kratz shot Finocchiaro in the head and DiNardo took the gun and shot him again. Dinardo told police that he shot Meo in the back, and as Sturgis started to run away, Dinardo shot Sturgis, killing him.
At the DiNardo farm property in Solebury, Finocchiaro is shot and killed and placed in a metal tank, which DiNardo called a "pig roaster". "He dug a hole, he spent the time to burn the bodies, and he spent the time to cover it up". Viewers could watch investigators haul up buckets of dirt and sift it through handheld screens in what looked like an archaeological dig.

Lang said that DiNardo told police where the four bodies are located.
"We're not going to rest until we get through every inch of that property", Weintraub said, according to The Associated Press. Finocchiaro had come to buy drugs; Kratz and Dinardo had planned to rob him.

Second Man Charged In Deaths Of Four In Pennsylvania
DiNardo and Kratz allegedly murdered the three others two days after Patrick, during two separate drug deals. The two then placed Finnochario's body in a metal tank DiNardo referred to as a "pig roaster".
Susan Coleman told news outlets that she and her husband were in their backyard last Saturday afternoon when they heard several rounds of what they believed was shotgun fire coming from the direction of the DiNardo farm.
It is still unclear why DiNardo killed the men, but the source said DiNardo had "felt cheated or threatened during three drug transactions".
Dinardo was released on bail on Tuesday when his father paid 10% of the $1 million bail in cash.
On Thursday, DiNardo's lawyer announced that his client had admitted to the killings and was cooperating with investigators. He said he took Finocchiaro in his vehicle but kicked him out after declining to sell him drugs and then spent the rest of the night fishing. An affidavit in that case said he is "known to be suffering from mental illness". DiNardo was accused of illegally possessing a shotgun and ammunition after being involuntarily committed to a mental institution.
Investigators say this is Meo's auto.
During the second interview with police, DiNardo told investigators he had arranged a marijuana deal with Meo on July 7 and they agreed to meet near a church in Peddler's Village in Bucks County.
DiNardo was the first to be arrested Thursday and confessed after authorities agreed not to seek the death penalty.
