DAVENPORT, Fla. – A 43-year-old man shot and killed his adult stepson Wednesday night in Davenport after the stepson’s 9-year-old brother grabbed a gun following an argument over the video game Fortnite, according to police.

Kelly Agar Garcia was arrested on charges of second-degree murder and unlawful storage of a firearm.
