DEKALB COUNTY, Ga. - A Decatur man accused of killing his grandmother and hiding her body along Interstate 20 was indicted by a grand jury this past week.
Jurors voted on a five-count indictment against 35-year-old Gregory Williams for charges of malice murder, felony murder, aggravated assault, concealing the death of another and theft by taking in connection with the murder and disappearance of his grandmother, Millicent Williams.
Williams, 78, was missing for weeks, but officials used dental records to positively identify her body. She was reported missing on July 27.
Gregory Williams, was originally taken into custody in August and charged with theft by taking for being in possession of Williams’ vehicle. Charges of kidnapping, while murder and aggravated assault charges were added later.
Police believe Mr. Williams forced his way into his grandmother's bedroom and attacked her with a "Rambo-style" knife, according to released warrants.
Court documents state that the assault happened at Millicent Williams' Brookgreen Point home sometime between Sunday, July 22, and Thursday, July 27. Police allege he then kidnapped her and got rid of her body with her own car, but the documents don't reveal specifics.
The warrants outline how investigators found a lot of blood inside her home and in her car, including on the rear floorboard. Authorities arrested Williams last week while he was driving her car, and the documents say he had a bloody knife at the time.
Police said someone made the discovery behind a guardrail on the westbound side between the Flat Shoals Road and Glenwood Road exits.
Police Spokesperson Shiera Campbell told FOX 5 News the body was so badly decomposed investigators couldn't determine if it belonged to a man or a woman.
The case will be prosecuted by the DeKalb County District Attorney's Major Case Unit. A trial date has not been set.
