The state medical examiner’s ruling that a two-month-old boy’s death was a homicide has resulted in the indictment of the child’s father on murder and child abuse charges. The Dickson County Grand Jury indicted 30-year-old Robert E. Huse of Jones Creek Road in Dickson for second-degree murder and aggravated child abuse earlier this week. An autopsy revealed that Huse’s two-month-old son Grayson died Sept. 24 as a result of blunt force trauma to the head. The child’s death was originally thought to have been the result of natural causes until the medical examiner’s report was issued in January. When the boy’s mother, Brittany Sanders, brought a copy of the report to Dickson Police, Det. James Eubank opened an investigation that led to this week’s indictment. Huse has been arrested and is being held in the Dickson County Jail on $500,000 bond. Eubank said the child, identified in the indictment as Grayson Michael Sanders and on his gravestone as Grayson Michael Bowker-Huse, had been in the hospital for four days in September but within hours of being released there was a 911 call to the father’s home and the child later died. Huse pleaded guilty to accessory to child abuse after the fact in 2008 after a five-month-old child had suffered a head injury. He was placed on probation for two years. That child’s biological mother, who is no longer married to Huse, received three years of probation. Custody of that child and a sibling was given to their grandparents but they were returned to Huse two years later. Once the death of Grayson Huse was ruled a homicide, the two older children were placed in Department of Children’s Services custody.
