Authorities have released a composite sketch Thursday of a suspect in the drive-by shooting of Jazmine Barnes, the 7-year-old girl killed while sitting in a car outside of a Houston-area Walmart.

The sketch was created from descriptions provided by Jazmine’s mother, LaPorsha Washington, and her three sisters, who were all in the car during the shooting.

The suspect is thought to be a thin White man in his 30s-40s with blue eyes and stubble.

Texas police said the shooter pulled up next to the family’s vehicle in a red pickup truck before opening fire early Sunday.

Jazmine’s senseless death has received national attention for its perceived racial motive. Although countless tips have poured in about the incident, the gunman remains at large.

The Harris County Sheriff’s Office also released an enhanced surveillance video of the suspect’s truck.

“We’re not going to rest until we find justice for Jazmine,” Harris County Sheriff Ed Gonzalez told reporters.

Journalist/activist Shaun King and others have offered a reward of $100,000 to anyone who can provide information on the suspected gunman.
