Person of interest in USPS letter carrier’s killing in DeKalb arrested

“At this moment he has not been charged federally, as he is being held on his previous murder warrant,” Steverson said.

Tuesday evening, officials with the U.S. Postal Inspection Service and the FBI executed a search warrant at a residence near the site of the shooting. Williams is believed to have lived at the house, but authorities clarified it was not necessarily his permanent residence.

During a news conference in the area, a USPIS official confirmed Williams was taken into custody in Atlanta before the search warrant was executed.

A $250,000 reward was offered for information leading to the arrest and conviction of the person involved in Graves’ death. Authorities said the amount is standard for homicide investigations involving USPS employees who are on duty.

Tuesday’s arrest was a result of investigative work and tips, according to law enforcement.

“We’re very sorry for the loss of Dequavious. It’s tragic when we lose anybody in the postal family, and we take it very seriously protecting our personnel,” a USPIS officer said.

In the previous killing Williams was tied to, an arrest warrant accuses him of shooting Donato Bradford at a northwest Atlanta student housing complex. The incident happened at the Westmar Lofts at 800 West Marietta Street on July 30.

Williams is facing charges of murder, aggravated assault and possession of a weapon during the commission of a crime in that case, according to court documents.
