Charvon Johnson was 19 when he was found behind an abandoned house in the 3000 block of Jackson Avenue in Baton Rouge on the evening of December 4, 2018. He had suffered critical gunshot wounds and died after being taken to a local hospital. Investigators initially had no identified suspects and the motive was unknown.

The probe continued for several months. In late February 2019 authorities arrested a 17-year-old male, Dayln Hynard, who was 16 at the time of the shooting. He was charged with second-degree murder, possession of a handgun by a juvenile, and illegal use of a weapon and was to be tried as an adult. Johnson’s mother reported her son had connected with Hynard on social media to arrange the sale of a gun and said the encounter led to a robbery in which Hynard shot Johnson and took the firearm.

Does anyone have information about Johnson’s movements that evening or about the arranged sale on social media?
