A 16-month old Victoria girl was critically injured about 4:30 p.m. Thursday in her home at 513 Lunenburg Ave. She died Saturday.

Aja Cofield was unresponsive when the Victoria Rescue Squad. Her 27-year-old stepfather, Mario Davis, called 911 and reported that the child had fallen down the stairs of the home, Lunenburg County Commonwealth’s Attorney Robert Clement said.

She was taken to Community Memorial Hospital in South Hill, and quickly airlifted to VCU Medical Center in Richmond.

She was kept alive on life support until 3:53 p.m. Saturday.

“After receiving medical opinions from the treating physicians, lead investigator A.A. Bruneau obtained a warrant for the arrest of Davis on Friday, June 10,” Clement noted in a statement. “Davis was detained at the hospital before the child’s death on Saturday, June 11, and transported back to Lunenburg where he was served with the felony warrant at 4:30 p.m. on a class 2 felony of aggravated malicious bodily injury which carries a sentence of 20 years to life in prison.”

Additional charges will very likely be obtained in the near future, Clement said.

“Initial investigation by Bruneau and the Department of Social Services has revealed that Davis and a three-month old baby were the only other persons in the home at the time, and that the medical opinion is that the injuries to the child are not consistent with a fall down the stairway, but consistent with abusive head trauma,” Clement noted.

An autopsy is being conducted by the State Medical Examiner’s Office this week, possibly Tuesday, he said.

The child’s mother Marrisa Cofield, 26, was said to be at work at a retail store in a South Hill at the time of the incident, Clement said.

Davis, who is six feet, four inches tall and weighs 250 pounds, will appear in Lunenburg District Court this week for advisement of his right to an attorney, Clement said. A date for a preliminary hearing will be set later.

He is currently being held in Piedmont Regional Jail with no bail set. There is a statutory presumption against bail for his charge, Clement said.
