Bibb County Coroner Leon Jones said the three-month old, Desmond Hicks, died from blunt force trauma to the head.
This autopsy comes just one day after 25-year-old Richard Allen Hicks III, was arrested for Felony murder charges for death of his infant son.
Police were called to Summit Apartments on Saturday after a report concerning an unresponsive baby. According to a police press release, medical personnel determined that the infant's injuries were highly suggestive of non-accidental injuries or abuse.
Maurice Jackson, the maternal grandfather of Desmond Hicks, declined to be interviewed on camera, but he gave us this statement.
"We thank everyone for their prayers and heartfelt condolences. At this time, we would just let the court do its job for justice."
13WMAZ talked to some who live at the apartment complex. They didn't know the family, but said they were surprised by what happened.
"Awful, it's very awful," said Charlotte Edwards of Macon. "I couldn't imagine, me being a mother, I couldn't imagine."
"It's real quiet. A lot of kids be out here playing around and stuff like that," said Byrant Harrison of Macon. "I wouldn't expect nothing like that like around that especially not at Summit."
And those we talked to said that their prayers are with the family during this tragedy.
"There's not much that's going to bring your comfort except your belief in a higher power because that's just horrible," said Jacqueline Larry of Macon.
