On the late afternoon of August 22, 2017, 19-year-old Briana Hornsby was shot while driving in the 10900 block of Florida Boulevard in Baton Rouge. A passenger, 20-year-old James Seymore of Ponchatoula, reportedly began playing with a handgun; the weapon discharged and a single bullet struck Hornsby. She was taken to a nearby hospital and pronounced dead.

Seymore fled on foot immediately after the shooting. The Baton Rouge Police Department identified him as responsible, and a warrant was issued charging him with negligent homicide and illegal use of a weapon. He later surrendered to authorities. The community was shaken by the fatal result of casual gun handling.

What details about that afternoon might help explain how a moment of recklessness became a homicide, and does anyone have information about witnesses or the vehicle involved?
