I would consult a Utah wrongful death attorney immediately so he or she can investigate the facts surrounding the event. Also an autopsy needs to be done. These are very expensive to litigate which is why it would be best to talk to an attorney over the phone or in person to discuss all the facts.
You may have a good case. The outcome will depend on many factors, some of which you may not have thought about. Many attorneys will offer a free consultation, I would suggest that you contact one a set up an appointment.
