The 20-year-old suspect in the disappearance of four Pennsylvania men has reportedly confessed to killing them, saying he felt cheated or threatened when he sold drugs to them. AP cited a person described as having knowledge of Cosmo DiNardo's confession as saying he admitted to then burning their bodies at his family's Bucks County farm. The source also said there was a co-conspirator involved in the deaths of three of the men. One of the bodies was discovered earlier this week on DiNardo's family's farm, and he told investigators where the other men's bodies were located. He also agreed to plead guilty to four first-degree murder counts, and in return for his cooperation, prosecutors agreed not to seek the death penalty. As he was led from the courthouse yesterday (July 13th), DiNardo told reporters "I'm sorry" when asked if he had anything to say to the victims' families. The men killed were: 19-year-old Dean Finocchiaro; 22-year-old Mark Sturgis; 21-year-old Tom Meo; and 19-year-old Jimi Taro Patrick.
