The grand jury indicted a Wise County couple for child abuse and neglect of their infant son.
The father, 44 year-old Franklin Mullins, was accused last month for the death of the baby's twin brother.
Shortly after the investigation into 5-month-old Ryan Mullins' death began, the Wise County Sheriff's Office started looking closer into the death of his twin brother, also named Franklin Mullins who died two months earlier of an E. Coli infection.
The father is now charged with two counts of child abuse and neglect against his son Franklin.
He’s already accused of felony murder, second-degree murder, child abuse and neglect of his other son, Ryan.
The sheriff's office began investigating when they responded to the call of an unconscious baby.
Ryan was flown to the Johnson City Medical Center where he died a few days later of a non-accidental head injury.
The grand jury indicted the boys' mother, Viola Mullins. She was arrested on two counts of child abuse and neglect of Franklin Mullins. She is being held on a $100,000 secure bond.
