Kendra La Sheka Lewis, 27, was driving a blue Toyota Corolla through the parking lot of a Citgo station at Silver Star and Pine Hills roads Wednesday when gunfire erupted, sheriff's Capt. Angelo Nieves said.
Lewis was taken to the hospital in critical condition. She was taken off life support Thursday night and pronounced dead.
Her 5-year-old daughter, who was in the back seat, was uninjured.
When deputies got to the gas station, they found a group of 50 to 75 people. Most said they did not want to talk to authorities.
One man who was inside the gas station during the shooting said students from Evans High School, which is just across the street, often fight in the parking lot. So when he heard yelling outside he thought that's what it was, a sheriff's report stated.
He went outside, heard several gunshots, then saw a teenager, wearing a dark-colored shirt and blue pants, hop into a white SUV that sped away, according to the report.
Then he looked over and saw Lewis bleeding in her car.
The man said there were two others in the SUV, but he got a good look at one. only The teen was black, 17 or 18 years old, about 5-feet, 8-inches tall and weighed somewhere between 175 and 180 pounds, investigators said.
Deputies found Lewis in her car, her passenger-side window smashed. Bullet casings and pools of blood surrounded the front of the vehicle.
The gas station was surrounded in yellow crime-scene tape as investigators took photos of the scene. A car seat lay on the ground next to glass fragments.
Authorities say Lewis wasn't the target of the shooting but was an innocent bystander who was in the wrong place at the wrong time.
Leonie Dowdie, 26, was leaving Winn-Dixie when she heard the commotion.
She ran over and saw a man yelling and crying and a bloody woman in the driver's seat. Dowdie said her face was swollen near her eye. Emergency workers were tending to her wounds.
Dowdie said she has lived in Pine Hills for most of her life but doesn't remember violent crime being this bad.
"It's like every day or ever other day. It just won't stop," Dowdie said. "You can't even leave your house or get gas without being shot."
Photos on Lewis' Facebook show her smiling and posing with her daughter and a boy identified as her young son.
No one has been arrested in the shooting, which is the latest in a string of shootings and other violent crimes in Pine Hills since October.
