I used to live right down the street from there off Dauphine St... if it’s the same gas station I’m thinking at that intersection, I once saw a man shot dead laid out in the parking lot. There were also plenty of feral youth always begging for money.
From further reports, the atv riders had been riding all over the area. Hardly 4 wheelin’ territory so my guess is they were assclowns and got confronted by an irate resident.
