An autopsy today should tell DeSoto detectives whether to charge a boy's father with causing the 12-year-old's death. Jonathon Potts died while riding with his father in the family van yesterday -- and paramedics who worked on him grew suspicious when they found some old bruises and some recent cuts on his body. Police quickly arrested the father Terence Potts on charges of causing an injury to a child. But depending on what's learned in today's autopsy, the charges could be much more serious. Jonathon has two sisters -- CPS has already taken them into foster care.
