Eric Black Jr faces a capital charge killing Jazmine's death. The second grader boarded a car along with his mother and three sisters when he was taken off the head on the morning of December 30.
S. Lee Merritt, an attorney advising the Barnes family, said the arrest was a "welcome news to the family."
"At the same time, a big shock to the family," Merritt told CNN on Sunday morning. "To this point, at least four independent witnesses and a composite sketch identified the main suspect as a 40-year-old white man."
Although it may be difficult to understand the difference, "it is thought that the witnesses are troubled by a runaway for the actual shooter," Merritt tweeted.
A possible case of mistake identification
after killing Jazmine, the sheriff's office and Jazmine's mother said the shot seemed unintentional. Like the departure of the suspect authorities, so is the motive.
Now the authorities have said that the gunman may be trying to shoot other people. "At this time, investigators did not believe that Jazmine's family was the intended target of shooting, and possibly shot them as a result of false identities," said the sheriff's office.
"Investigators continue to carry evidence that could lead to other suspects charged in this case."
How the morning morning was tragic
In the morning of The death by Jazmine, she and her sisters are on their pajamas as their mother drives Joe's Smart Shop to get breakfast supplies.
At about 7am, a man brought along their car and opened fire, Jazmine's mother LaPorsha Washington said.
30-year-old Washington was shot in the arm, while Jazmine's 6-year-old sister was hit by broken glass. The two girls of Jazmine were not hurt.
But after a few minutes, Jazmine was pronounced dead.
An outpouring of support
Washington still returns from his gun wound, thanks to all who come from honor to his daughter. Jazmine said she will celebrate her birthday next month.
"I tell you, whenever I see one of those who interact with me, I can lift my head," he said. "I can get up in the morning."
The tragedy of Jazmine's death has had an effect on the whole nation.
