I need help finding a laywer. My father went in to the hospital for abdnominal pain and diarehea. In a little under four months he was gone.

I am sorry to hear about your dad. First, your oldest sibling, as executor, will need to request al medical records related to this incident -- starting with the first hospital visit and get all medical records and bills after that which were related to this in any way.  In the meantime, start contacting Plaintiff's attorneys who focus on medical malpractice cases.  Start calling lawyers and try to get a consultation set up.  Most attorney's will provide free consultations and they will want to see these medical records.  You need to find a local attorney (it likely will need to be an attorney in the same state where you father received the hospital treatment which you believe led to his death).  Medical malpractice cases are very difficult and time consuming, which is why the attorney will want to review the records in order to determine if they can help you.  While all state laws vary, most state laws make it difficult for someone to sue a hospital or other health care provider.  In addition, please note that there is a limited amount of time in which you can file suit.  These limitations also differ by state so it will be helpful for you to consult a local attorney.  I am sorry that I was not able to provide any further assistance based on the information you provided in this post, but I hope this helps.  Since consultations with most all plaintiffs attorney's are free, I recommend you gather the medical records and bills and go in for a few consultations.  Good luck!
