DEKALB COUNTY, Ga. (CW69 News at 10) — Nearly nine months after DeKalb County police shot and killed Matthew “Zadok” Williams, activists took their fight for justice inside the county administration building.

“Ain’t no justice in this town,” the group chanted.

The activists and family members brought a petition with roughly 40,000 signatures with them in hopes of personally delivering it to DeKalb County CEO Michael Thurmond. They’re demanding justice after Police Sergeant Devon Perry allegedly shot and killed Williams last April. Officers were responding to a call about a suspicious man with a knife.

Family members say they’re still waiting for Thurmond, Police Chief Mirtha Ramos, and District Attorney Sherry Boston to take action. They’re specifically demanding the DA prosecute Perry and all officers involved in Williams’ death and that Ramos and Thurmond fire or at least suspend Perry while the DA reviews the case.

“What type of culture are they continuing to support by doing nothing with this milk-toast attitude towards the murder of my son,” said Chris A. Lewis, Williams’ mother.

At the rally, community activists demanded justice from authorities.

“If he’s not safe in his home, what makes you think you’re gonna be safe in yours,” said Nathan Knight, the chairman of the DeKalb Southern Christian Leadership Conference.

Advocates for the family reiterated the violations that they want to see county authorities act upon.

“There are four clear-cut violations that we’ve presented to the CEO,” said Mawuli Davis, the family’s attorney.

The alleged violations include failure to contact S.W.A.T., officers not keeping their distance during a reported mental health crisis, excessive force, and failure to render aid. The group said it had reportedly scheduled a meeting with Thurmond to deliver the petition in person, but he didn’t show up.

When contacted by CW69 News by telephone, Thurmond’s office said there was no scheduled meeting to discuss the case.

“We’re going to get justice, and his death will not be in vain,” Lewis said.

Chief Ramos had no immediate response to the presentation by attorneys. Officials from the county and the district attorney’s office said the case remains under investigation, and the Georgia Bureau of Investigation is involved in the ongoing investigative process. Boston’s office says there is no timeframe in terms of when she will make a determination regarding any action regarding the case.
