The Big Horn County sheriff's office says a woman has been arrested in the death of a 3-year-old boy whose body was found in a parked car in Hardin. Coroner Terry Bullis says Jaren Blacksmith died of hyperthermia, or elevated body temperature, on Wednesday as temperatures reached the low 90s in Hardin. An investigation led to the woman's arrest on Friday on suspicion of negligent homicide. Her name has not been released. She is scheduled to be arraigned this week. The boy was from Lodge Grass but was in a foster home in Hardin.
