Marcus Thomas, 24, was one of three people found shot dead inside a Honda Accord parked in a driveway on the 6000 block of Byron Street in Baton Rouge. Police discovered the bodies of two men and a young woman during a predawn check of a suspicious vehicle on July 9, 2009. The other victims were identified as Adrian Stewart and Gabriella ’Gabby’ Eisworth. Neighbors reported hearing muffled gunshots, and investigators said all three died of gunshot wounds.

Early in the investigation police reported no suspects and no clear motive, though some early accounts noted signs that the encounter may have involved drugs and described the killing as another instance of street-level gun violence. In March 2012 a grand jury returned an indictment charging Hakeem Mumphery with second-degree murder in the case; another person, Darrelle Harris, had been considered a suspect but was not indicted.

If anyone knew Marcus Thomas or has information about the events on Byron Street that morning, please share what can help the investigation.
