A 21-year-old man was shot dead and a 22-year-old man was critically injured around 10 p.m. Thursday as Muses rolled past the 1200 block of St. Charles Avenue, between Clio and Erato streets, according to the New Orleans Police Department.
The 21-year-old died from a gunshot wound to the chest while in surgery. The other victim is in critical condition with a gunshot wound to the neck.
One male suspect is in custody, NOPD said.
Speaking to reporters at the scene, NOPD Superintendent Michael Harrison said the suspect initially fled and was caught at the intersection of Martin Luther King Jr. Boulevard and Baronne Street. A gun was also recovered, he said.
Two or three shots could be heard, after which the crowd scrambled and frantic parents herded their children to safety. NOPD, who were nearby when the shooting occurred, descended quickly afterward. They administered CPR to the man in front of a Popeyes restaurant as a young woman wailed. He was taken away by New Orleans EMS around 10:15 p.m.
Harrison called the situation "exteremely frustrating" as Mardi Gras draws closer but added that officers were "right there on spot" and did "great work" in catching the suspect.
The parade continued to roll amid the chaos, with some bystanders apparently unaware of what had occurred, continuing to follow floats and call for beads.
In 2012, two people were shot in the same area on the day Muses rolled.
