Prosecutors said Sunday that the shooting death of a 7-year-old black girl as she rode in her family's vehicle stemmed from a case of mistaken identity.
This undated image provided the Harris County Sheriff's Office shows Eric Black Jr.
In a statement, it said investigators identified Black as a suspect after receiving a tip.
Police released a composite sketch of the man they believe fired on the family's vehicle on December 30, killing Jazmine.
"We do believe that it was racially motivated in part because our nation at this moment is a highly racially charged society".
Jazmine's death has prompted an outpouring of support for her family from people, celebrities and sports stars across the country.
"I have no tint on my windows or anything so you can see there is a mother-a black mother-with daughters, handsome children", Barnes's mother LaPorsha Washington, told CNN after the shooting.
It was still dark out the morning the shooting occurred, Gonzalez pointed out, and Jazmine's mother and sisters had just gone through a traumatic experience, which could have affected their perception of those devastating moments.
The source told police that the suspects had mistaken the auto Jazmine was riding in for somebody else's and that it was shot at "by mistake".
Multiple news outlets are reporting that the police are very close to making an arrest.
She thanked them for their support and said of the killer: "We gonna find him no matter what corner we have to turn, no matter what rock we got to go under, we gonna find you man".
"Mr. Black has acknowledged his role in Jazmine's murder", Gonzalez said.
The sheriff released an artist's sketch showing a thin, white man in his 30s or 40s with a 5 o'clock shadow. A $100,000 reward was offered for information leading to an arrest. "You took my baby from me and you have no care in the world".
The Harris County Sheriff's Office appeared to confirm the report on Saturday night when they tweeted the investigation has taken a "new direction". Houston-based rappers Paul Wall and Trae tha Truth asked the crowd to reach out to authorities if they have any information on the shooter. Houston Texans wide receiver DeAndre Hopkins pledged to donate his $29,000 paycheck from Saturday's playoff game against the Indianapolis Colts to help pay for Jazmine's funeral. Her funeral is at noon.
