CALERA, Alabama -- A 24-year-old Calera man has been charged with capital murder in the death of his 4-month-old son, Calera police announced today.
The child, Tremain Gates, Jr., died Tuesday at Children's of Alabama.
The boy's father, 24-year-old Tremain Vanteas Gates, is now being held without bail in the Shelby County Jail. Gates had been held on $1 million bond since August 30 on an assault charge stemming from the child's injuries.
Court records state the elder Gates was watching the little boy on the night of Aug. 25. Records stated the child was thrown against the wall and on the floor.
When the mother returned to the Sumner Drive apartment the next morning, the boy "was not acting like his normal self, could only open one eye, had a whimper ... and was lethargic," those records stated.
The child's mother took the boy to Shelby Baptist Medical Center and from there he was flown to Children's of Alabama.
