Update 9:15 p.m. EDT: The New Orleans Police Department is still looking for three suspects believed to be responsible for the attack.

“Obviously, these are unusual circumstances,” NOPD Supt. Ronal Serpas told WDSU. “It appears that these two or three people just for a reason unknown to us started shooting at towards or in the crowd. It was over in just a matter of seconds. Police were everywhere.”

“Maybe two different types of weapons,” Serpas said. “Immediately after the shots were fired, our officers saw three people running away.”
