Police: 4 wounded in shooting on New Orleans' Bourbon Street By NBC News staff and wire reports Two men and two women were shot in New Orleans' Bourbon Street after gunfire broke out while crowds gathered in the countdown to annual Mardi Gras festivities, police said on Sunday morning. Three of the victims were listed in stable condition while a male victim was in surgery and listed in critical condition, New Orleans Police spokesman Frank Robertson said. No suspect had been identified, Reuters quoted Robertson as saying. Crowds gather each year in New Orleans' French Quarter for celebrations that build to a climax on Fat Tuesday, which this year falls on February 12. The Associated Press reported the following: Patrick Clay, 21, an LSU student, told The Times-Picayune he was standing on the corner of Bourbon Street when suddenly he saw a crowd running and people screaming that there was a shooting. "Everyone immediately started running and the cops immediately started running toward where people were running from," Clay said. I was with a group of about seven people and at that point we all just kind of grasped hands and made our way through the crowd as soon as possible. Afterward, police moved in to investigate. Many revelers said they stayed hunkered down in bars and other establishments until police cleared them to move freely.
