The American flag flies at half staff to mourn the victims of the Connecticut school shooting, at the US Embassy in Rome, Saturday, Dec. 15, 2012. Police said Saturday they had found "very good evidence" they hoped would answer questions about the motives of the 20-year-old gunman, described as brilliant but remote, who forced his way into a U.S. school and killed 26 children and adults in one of the world's worst mass shootings.
