HOUSTON --A mother of five was shot and killed after a road rage confrontation and it could take days before the woman arrested for the killing is charged. That woman was still at the county's homicide division on Tuesday night even though Eyewitness News learned the Harris County District Attorney's Office has decided to let a grand jury determine whether she should be criminally charged. She told investigators she was scared and she was just defending herself when she shot and killed the mother of five. It didn't take long for the victim's children to find the place where their mother was killed. As sheriff's investigators were finishing up at the scene, we spoke to 15-year-old Tracy Newell, who was still numb from the news. "She was a good mom," Newell said. Earlier, he was so angry he took his frustration out on a window. "I got mad," he said. It was around 1:30pm Tuesday when deputies were called to the Korner Food Mart in the 12000 block of Bissonnet. Lying in the parking lot near her SUV was a 49-year-old woman. The shooter, also a woman, was nowhere to be found. Within minutes though, HPD had her in custody at her nearby apartment in the 3800 block of Synott and she was telling her side -- that road rage turned deadly. "From what she was saying is the person in the Expedition cut in front of her and then she was following closely and then the person Expedition started tapping her brakes and that just escalated. They both got angry, pulled into the parking lot and it went downhill from there," said Sgt. Ben Beall with the Harris County Sheriff's Office Homicide Unit. The shooter told investigators the woman in the Expedition pulled out a knife, so she grabbed her gun, shot her and took off. An eyewitness followed her down Synott, called police and when she saw them in her complex, she flagged them down and told them what happened. Investigators did find a knife at the scene and did corroborate her story with HPD. It is all too unbelievable for the victim's children. "My mom wouldn't fight anyone," Newell said. "My mom works seven days a week -- seven. She goes to work all the time, every day, comes home to cook for us, makes sure all the bills are paid. This ain't no way to go out," Jasmine Myles, another one of the victim's children, said. "It's sad, it's sad to take someone's life for something so petty. I mean, just walk away. All you have to do is walk away," said Lorena Mouton, the victim's neighbor. The victim's children identify her as Carol Grant, a home health care worker. The shooter hasn't been identified. Authorities say she did not have a concealed handgun license so that will also be part of the grand jury's case.
