– The family of one of four missing young men in Pennsylvania got the news they were dreading Wednesday night when authorities announced that the body of 19-year-old Dean Finocchiaro had been found in a deep grave on a suburban Philadelphia farm. District Attorney Matthew Weintraub said the body was found in a "common grave" more than 12 feet deep, though he didn't say whether the other remains found belong to the three other men who vanished last week, the Washington Post reports. The farm belongs to the family of Cosmo DiNardo, a "person of interest" in the case who was arrested Wednesday for stealing a car belonging to one of the missing men, the New York Times reports. DiNardo, 20, was bailed out by his father late Tuesday after being arrested on a weapons charge from earlier this year. Bail on the new charges has been set at $5 million. "We bought ourselves a little bit of time" with the stolen car charge, Weintraub told reporters early Thursday, adding that homicide charges are being seriously looked at. Eric Beitz, a friend of one of the missing men, tells the Philadelphia Inquirer that DiNardo sold drugs and guns and once boasted about having somebody killed. "Cosmo has spoken about weird things like killing people and having people killed," Beitz says. "Everybody you talk to about this guy, you hear he’s mentally unstable."
