After fighting for his life for four days, six-year-old Z’Mari Mitchell – shot in a reckless feud over a social media post – died in hospital on May 9, and now DeKalb Police is offering a $5,000 reward for information leading to the arrest of the child’s alleged killer Meshon Williams.

Police upgraded the 17-year-old’s charges to murder, from aggravated assault and aggravated battery.

Williams, also a suspect in several local auto thefts, has been on the run since May 5 when he allegedly sprayed a Decatur home with 31 gunshots, critically injuring Z’Mari as he played inside the living room.

The boy was in a critical condition from about 5:30 p.m. Saturday, when the shooting occurred, until he died from his injuries Wednesday, while still in hospital, police said.

Now a $5,000 reward is offered through Crime Stoppers for information leading to the arrest and indictment of Williams, who is about 5 foot, 11 inches tall and weighs about 150 pounds.

He was last seen driving away from the Decatur house, at 3539 Sweetgum Lane, in a gray SUV.

DeKalb Public Safety Director Joseph Lumpkin said the department won’t rest until Williams is in custody.

“We want Williams to know that we’re coming for him,” Lumpkin said during a May 7 press conference. “We’re coming for those who are involved in these groups creating this violence.”

Both the DeKalb fugitive squad and all DeKalb police officers are searching for Williams.

Captain A.T. Mears said Williams was one of seven people who went to the Sweetgum Lane house with a purpose on Saturday.

“They went there to engage in a fight over a social media post that they did not like,” Mears said.

Police say Williams is considered armed and extremely dangerous.

Anyone with information about his whereabouts is asked to call DeKalb Police at 770-724-7850 or Crime Stoppers at 404-577-8477.
