A suspect has fatally shot two people at a gun store in a suburb of New Orleans, with the shooter also dying during gunfire, authorities say.
Jefferson Parish Sheriff Joseph Lopinto said a person he described as the initial shooter fired inside the Jefferson Gun Outlet on Saturday afternoon in the suburb of Metairie, striking the two people who were later pronounced dead.
He said several other people - whether employees or store customers - then opened fire on the shooter, both inside and outside of the building.
The suspect also was killed, according to Lopinto.
Guns and ammunition are sold in the front of the outlet and staff who work there often wear a side arm.
Lopinto said two other people were also hit by gunfire and were hospitalised in stable condition. He said there were multiple shooters in all and investigators had just begun trying to piece together what happened.
None of the dead or wounded were immediately identified and details remained sketchy.
Lopinto said the investigation was continuing as authorities tried to determined the exact details of what happened.
Caution tape surrounded the business to keep onlookers from getting close to the scene, where ambulances and numerous law enforcement vehicles had arrived earlier.
