Barnes was killed Saturday in the back seat of her mother’s car when an alleged gunman drove up next to the vehicle and shot into the vehicle, per reports.

A manhunt is underway for a bearded White man in his 40s, according to law enforcement officials.

Police officers are looking for a suspect who allegedly shot and killed a 7-year-old Texas girl in the back of her mother’s car.

Jazmine Barnes and her mother, LaPorsha Washington, were shot Sunday after they were going to get coffee, according to ABC 13 in Houston.

Washington, who was with her three other daughters in the car, opened up about the attack to the news station, saying a man driving a maroon pickup truck pulled up next to her and started shooting into her vehicle.

“As I turned around and looked back at the street, I heard shots start firing and they came through my window, broke my glass, and hit me in my arm. They sped off in front of us and the truck slowed down and continued to fire as he was in front of us,” she told ABC 13. “It was not fair. It was not fair. He intentionally killed my child for no reason. He didn’t even know her, he didn’t know who she was.”

Washington, 30, said after the shooting, her other daughter informed her what had happened to Jazmine.

“She said, ‘Momma, Jazmine’s not moving. She’s not talking.’ I turned around and my 7-year-old was shot in the head.”

The Harris County Sheriff’s Office is looking for the suspected shooter and “won’t rest until this precious child’s killer is brought to justice,” according to Sheriff Ed Gonzalez.

Civil rights attorney Lee Merritt and activist Shaun King have offered a $35,000 reward to anyone who has any information on the person who shot and killed Jazmine.

Two of Jazmine’s sisters weren’t hurt in the incident, but her younger sister was injured by glass fragments; their mother was taken to the hospital, according to Yahoo News.

“My baby comes and asks me, ‘Where’s my sister? Is she coming back?’ She’s only six years old,” said Washington.

Jazmine’s family has set up a GoFundMe page to help with expenses.
