Jaquavia Jackson was arrested on Friday and charged with two counts of aggravated assault, two counts of murder, and two counts of possession of a firearm during the commission of a crime.
Officials said Deputy Shakeema Brown Jackson and her brother Levoy Brown died Wednesday in a shooting in Newton County. They were both shot multiple times at Jackson's Covington home at around 10:30 p.m. Wednesday night, investigators said.
Jackson had been with the Fulton County Sheriff's Office since 2018 when she started as a detention officer. She had just become a deputy sheriff a month ago.
A judge denied bond for Jackson during his first appearance.
