A 24-year-old man faces the possibility of life in prison after a federal grand jury indicted him for the murder of a U.S. Postal Service letter carrier in Decatur.

What we know:

Nahjel Malik Williams, 24, of Decatur, faces a two-count indictment charging him with first-degree murder of a federal employee and discharging a firearm in relation to the death of Dequavious Graves on Feb. 12. 

If convicted, Williams could be sentenced to life in prison or face the death penalty, according to federal prosecutors.

The U.S. Attorney General will make the final decision on whether to seek the death penalty in this case. 

Williams is currently in local custody while he awaits his arraignment on these federal charges.

The backstory:

Graves, 31, was shot and killed in the 2700 block of Oxford Drive near Flat Shoals Road just before 7 p.m. while performing his job. Federal prosecutors allege the killing of the letter carrier was planned in advance.

At the time Graves was killed, Williams was already wanted for a different murder involving a 2024 shooting at the WestMar Student Lofts in Midtown Atlanta.

Williams has an extensive arrest history in both Cobb and Fulton counties. 

What we don't know:

Authorities have not released the specific evidence they have that leads them to believe the murder was premeditated. It is also not yet clear if Williams and Graves knew each other before the shooting took place.

What they're saying:

"The murder of Dequavious Graves, a letter carrier dedicated to his public duty, friends, and family, was a senseless crime and a horrible tragedy," said U.S. Attorney Theodore S. Hertzberg. 

Hertzberg added that anyone who harms letter carriers during their work "will be brought to justice in federal court."

Rodney M. Hopkins, inspector in charge of the Atlanta Division, stated that the arrest shows the dedication of postal inspectors and law enforcement partners.

"With these charges, we hope to bring forth a sense of justice for Mr. Graves and his family," Hopkins said.
