Houston mom says man 'intentionally' killed 7-year-old daughter while leaving Walmart

HOUSTON, Texas -- LaPorsha Washington, mother of Jazmine Barnes, is revealing new details about the alleged attack that killed her daughter on Sunday morning.

Jazmine, 7, and her mother were shot as they were going to Joe V's to get coffee Sunday morning. Washington's three other daughters were in the car with them. They had just passed Walmart when a car pulled up.

Washington told ABC13 about her daughter's final moments.

"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. 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."

After the shooting was over, one of her other daughters made the devastating discovery.

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