Mother pleads guilty in child abuse case involving twin 3-month-old boys

Brittany Hefner, 25 of Connelly Springs.

A mother has been sentenced to prison time after admitting to shaking her 3-month-old child.

Brittnay Nichole Hefner, 25 of Connelly Springs, was issued a prison term of six to eight years on Thursday after pleading guilty to attempted felony child abuse inflicting serious injury.

The charges stem from injuries discovered on Hefner's 3-month-old son during an investigation into the death of the child's twin brother.

On January 31, 2016, Bruke County EMS were called about a child that was not breathing. That 3-month-old baby boy was taken to Brenner Children's Hospital in Winston-Salem, but died from injuries that investigators said were a result of abuse allegedly caused by the child's father, 21-year-old Nicholas Brandon Clark.

Clark has pending charges for murder and felony child abuse inflicting serious injury in the death of his son. 

The twin brother of the 3-month-old was also taken to the hospital to be evaluated. Injuries found on the child were consistent with being shaken, police said. Hefner admitted to investigators to shaking the surviving child two days earlier.
