A high school graduation party in Gentilly ended in tragedy on May 23, 2014, when gunfire on the 6200 block of Eads Street left 15-year-old Tremaine Robertson dead and seven others wounded. The shooting happened just before 11:30 p.m., turning a celebratory evening into a scene of chaos and sorrow.

The New Orleans Police Department identified 19-year-old Zachary Gibson as a suspect and arrested him at a residence on Sixth Street within days. He was charged with second-degree murder in Robertson’s death and seven counts of attempted first-degree murder for the injured partygoers. The motive was not immediately released as investigators continued their work.

In March 2016 Gibson pleaded guilty to a reduced charge of manslaughter and was sentenced to 30 years in prison. The community was left to reckon with the loss of a young life and the broader problem of gun violence. Does anyone who attended that party or knew Tremaine have information that could shed more light on what happened?
