The victims were on a nearby street when multiple suspects opened fire on them, Washington said.
News media report that the shooting started at a house party a few blocks away from the gas station.
The body of the victim who died on the scene could be seen in the back of a red Nissan sedan at the La Express gas station about 3.22 kilometers from where revelers gathered for Fat Tuesday celebrations.
Another victim was transported to the hospital by emergency services and died there. Three other victims were transported to the hospital in private vehicles. She said authorities did not have a motive at this time. The names and ages of the victims were not released.
Police cars with lights flashing were arrayed around the gas station and yellow police tape had been strung up to keep bystanders away. Dozens of people gathered on the median, looking on as the police conducted their investigation.
The first shooting happened about 3:15 pm Deputy Superintendent Paul Noel said one man was shot in the head and was in critical condition. Another, a juvenile boy, was shot in the leg and his condition was stable.
