Matthew Hartman Robertson, 16, was found shot inside a gold-colored SUV parked on West Main Street in Rock Hill, South Carolina, on the afternoon of Monday, July 26, 2021. Responding officers pronounced him dead at the scene from a gunshot wound to the chest.

Investigators say the two teenagers knew each other and had arranged to meet under the pretense of a marijuana sale. Police arrested a 15-year-old male the day after the shooting; investigators reported evidence including text messages and surveillance video from the parking lot. Authorities charged the suspect as a juvenile with murder, possession of a weapon during a violent crime, illegal carrying of a gun, and possession of a handgun by someone under 18.

Does anyone who knew Matthew or who was in that area on July 26, 2021 have information that could help clarify what happened?
