(CNN)A 6-year-old Georgia girl died this week after her 4-year-old brother accidentally shot her in the head in a car outside their home, authorities said.

The girl, identified as Millie Drew Kelly on a GoFundMe site set up for the family, was shot Monday evening at their subdivision about a 40-minute drive northwest of downtown Atlanta, the Paulding County Sheriff's Office said.
The siblings were in a car in their driveway, preparing to go to the boy's baseball game, when the vehicle failed to start. The mother exited to try to find out what was wrong with the car, authorities said.
The boy took a gun from the car's console and accidentally fired it while his mother was outside, striking his sister in the head, the sheriff's office said.
    Emergency responders were called and took her to an Atlanta-area hospital. Two days later, detectives learned the girl had died, the sheriff's office said.
    Detectives determined that no charges will be filed.
    "It's just a really sad situation," sheriff's Sgt. Ashley Henson said Saturday morning. "Just based on all the evidence and the entire situation, we felt like charges were not warranted in this particular case."
      Sheriff Gary Gulledge said that his officers' "hearts break for this family, and we hope God puts his healing hands around them during this difficult time."
      "We want to remind everyone to keep their firearms unloaded and secured in an area away from children to ensure that this never happens again," Gulledge said in a news release.
