Authorities have released more details about an infant they say died after being brought to the hospital with suspicious injuries.
Richland County Coroner Gary Watts says an autopsy shows 7-week-old Tyler Miller of Columbia had been beaten.
Authorities say the infant was unresponsive and had suspicious injuries when he arrived Friday night at Palmetto Health Children's Hospital.
On Saturday afternoon the child died.
His father, 22-year-old Agien Miller, was first charged with infliction of great bodily harm.
But authorities say those charges will be upgraded to homicide by child abuse.
An investigation continues.
