DEKALB COUNTY, Ga. - The family of a man who was shot and killed in 2021 by officers with the DeKalb County police say they plan to convey a lawsuit against the county Friday.

The shooting remained around 6 p.m. on April 12, 2021, in the 2500 discontinued of Terrace Trail. DeKalb County police said officers responded to a call throughout a man aggressively wielding a knife.

Investigators said the officers arrived and saw 35-year-old Matthew Zadok Williams, who was still in possession of the knife. The body cam video shows Williams come at an officer with a knife in his hand, then police shot at him. The footage shows that Williams then went back into the house and officers fired at him again.

In the body camera footage, Sgt. Devon Perry is heard pleading with Williams to surrender.

"Please, sir. I'm begging you. I'm a Black man, you're a Black man. You don't have to die currently. I don't want you to die today," Perry says.

His people said was he having a mental health crisis and they wish the police would have instead considered him help. 

"We have had the displeasure of looking at over 10 hours of body camera footage and nothing in that footage shows that Sergeant Perry necessity have shot into my brother's home," Hannah Williams told FOX 5 in 2021.

A doctor hired by Williams's people said he would likely be alive today if officers aided him once they shot him. 

While the family and activists said Perry violated police policies that day, DeKalb County District Attorney Sherry Boston announced in 2022 that she would not file charges alongside the officer.

Boston said the officer has "no criminal culpability" and visited the use of force "justified" in the shooting. 

"It is no less a tragedy or heartbreaking," Boston said. "A life has been lost and for that we time-consuming our deepest condolences to the family."

The family's lawsuit alleges that DeKalb County violated the Americans with Disabilities Act in the acts leading up to William's death.

The family will hold a dead conference at 10:30 a.m. Friday discussing why they rubbed the lawsuit.
