Scott Daniel Sparks, 30, of Kelso, is being held without bail on a first-degree assault of a child charge, after he allegedly injured a three month-old baby. The child was taken into St. John Medical Center last Monday, then was transferred to Legacy Emanuel Hospital in Portland. Hospital officials say that the baby’s injuries are consistent with “shaken baby syndrome,” and following that announcement, Sparks was arrested Friday afternoon. It’s reported that the baby is in critical condition, and that the injuries are life-threatening. The investigation into the incident is continuing.
