The Bucks County District Attorney has positively identified the bodies of four young men who were missing in Pennsylvania.

Dean Finocchiaro, 19, and 22-year-old Mark Sturgis, 21-year-old Thomas Meo, 21, and 19-year-old Jimi Taro Patrick were all killed separately, according to an anonymous source.

“I am relieved to say we have brought four young men one step closer to their loved ones so they can rest in peace,” said Bucks County District Attorney Matthew Weintraub.

Twenty-year-old Cosmo DiNardo has been charged with the murder of all four and investigators now say he had an accomplice Sean Kratz who is charged with three counts of homicide.

“They have also been charged with robbery, abuse of corpse and possession of instrument of crime,” said Weintraub.

Three of the bodies were found in a mass grave on the DiNardo family farm. The fourth victim was found buried about a half a mile away with information that DiNardo supplied in exchange for being spared the death penalty.

“And I can tell you because I have been there, we would still be looking for Jimmy Patrick’s body if I didn’t make that deal,” said Weintraub.

DiNardo has confessed to police. He reportedly told them he committed the murders after he felt cheated when selling the victims marijuana. Authorities say all the men were shot and that the suspects tried to set the bodies on fire. The DA says they have recovered two murder weapons.
