At 2:02 a.m. Monday, the names of 49 people killed in the worst mass shooting in modern U.S. history were read out loud outside the Pulse nightclub, marking the exact time a year ago when a gunman started firing during “Latin Night” at the gay club. “I realize that gathering here in this place, at this hour, is beyond difficult,” Orlando Mayor Buddy Dyer told survivors, victims’ families, club employees and local officials during the private service. “But I also know that the strength you’ve shown over the past year will carry you through today and in the future.” The service began what would be almost 24 hours of observations to remember the victims and the dozens of Pulse patrons who were wounded when Omar Mateen opened fire and pledged allegiance to the Islamic State. He was eventually killed by police after a three-hour standoff on June 12, 2016.
