Church bells tolled 49 times, a giant rainbow flag hung from a county government building and the names of the victims of the Pulse nightclub attack were read aloud at various ceremonies Monday as people in Orlando and beyond remembered the worst mass shooting in modern U.S. history. At 2:02 a.m., survivors, victims' families, club employees and local officials were gathered for a private service at the gay club at the exact time Omar Mateen opened fire a year ago and pledged allegiance to the Islamic State.
