Chicago police believe killing may have been gang related.
Two teens have been charged with murder following a drive-by shooting that killed a 6-year-old Chicago girl.
Aliyah Shell was shot dead just outside her house.
Investigators say a pickup truck approached the home Saturday afternoon and someone inside began shooting, striking the girl in the abdomen.
The little girl's sister was inside the house when she heard a popping sound outside.
"They started shooting but I thought it was fireworks. I heard like five or six gunshots. I thought they were fireworks," said Desiree Valzquez, Aliya's sister. "I ran outside, and my mom was holding my sister. My sister wasn't talking anymore. She wasn't breathing."
On Sunday afternoon police charged two teens with Aliyah's murder -- 18-year-old Juan Barraza, and a 16-year-old boy.
Both teens are charged with murder and aggravated discharge of a firearm.
