While her 4-year-old son was buried Saturday, officials said that the mother of Treymane DaShon Berry, who died Jan. 11, is expected to turn herself in for lying to investigators.
Demetria Denise Harris, 29, will be charged with making false statements in a government matter, a felony, said Richmond County sheriff's Sgt. Scott Peebles.
He said Ms. Harris agreed to surrender to authorities before noon on Monday.
Police say Treymane died after suffering massive head trauma, along with bruising and other injuries on Jan. 10. Ms. Harris' boyfriend, Jermaine Donald Boyd, 30, is charged with murder in her son's death.
Treymane's death is the first homicide in Richmond County during 2004.
Sgt. Peebles said that as the investigation began, Ms. Harris mislead officials about what happened on the night that Treymane received his injuries that lead to his death at Medical College of Georgia Hospital the next day.
"Initially, she claimed that she was present when 'the child fell down the stairs,"' Sgt. Peebles said. "We were able to disprove that."
