A Putnam County man mauled by two pit bulls last week died late Wednesday afternoon after being taken off life support. Roy McSweeney, 74, suffered brain damage from severe blood loss that occurred when the dogs severed one arm, partially removed the other and attacked his face, said Jennifer Biewend, his family's attorney. Capt. Johnny Greenwood of the Sheriff's Office said he was pronounced dead at 4:18 p.m.
