A 21-year-old Baton Rouge man was arrested after allegedly killing his mother’s boyfriend in a shooting Saturday evening off Gardere Lane in what the East Baton Rouge Parish Sheriff’s Office is saying started with a domestic dispute.

John Parker and his mother’s boyfriend, David White Jr., reportedly had a physical altercation at 8136 Skysail Ave., where they all lived, after which Parker fired multiple rounds with a handgun, according to Casey Rayborn Hicks, a spokeswoman for the Sheriff’s Office.

White, 39, and his juvenile child were both shot. White later died as a result of his injuries, and the child suffered non-life-threatening injuries.

Parker fled the area on foot, but detectives later located and arrested him on Chimneywood Drive for first degree murder and attempted first degree murder.
