How do to appeal to State Prosecutor to reopen a fair investigation into two years old wrongful death who was put into above ground incomplete pool

I'm so sorry to hear about the death of such a young child.  There must be many unanswered questions, and heartache.  It seems as though you are saying there was no answer as to how the child got into the pool because there was no access.  Have you found additional information that would lead the prosecutor to open the case? You can seek to have the report reviewed by the State, and point out deficiencies or areas where you feel more work needs to be done.  However, you might be faced with a situation where you will never be able to find out how that poor child got into the pool.  If you want to discuss this matter further, please call my office.
