Trevor Harrison, 27, was killed on the evening of February 15 in Baton Rouge while working as a plumber. He was sitting in his truck on Fairfields Avenue finishing a job for an elderly man when a stray bullet struck him; he died at the scene. Harrison was about to complete a civil engineering degree and was remembered by family as a hardworking, compassionate son and brother who had plans to go bowling with his family that night.

Investigators later linked the shooting to a multi-agency probe into a group described as the Shiesty Gang Kartel. Four people were arrested in connection with the killing: 18-year-old Dakhire Matthews, 18-year-old Steven Hackett, 17-year-old Christian Hardesty, and an unnamed juvenile female. They face charges including first-degree murder and attempted first-degree murder among other counts.

What information might help clarify the sequence of events that night or the connection between the suspects and the shooting?
