In a letter to friends and family, Nancy Kerrigan says the official cause of death for her father -- homicide -- was "unjustified" and her family plans "to help my brother fight."
The Medical Examiner determined Dan Kerrigan died from cardiac dysrhythmia after suffering a neck injury during a fight with his son, Mark.
Nancy writes her father "was the ultimate role model. We will miss my dad every day ... our family is stronger for having had him in our life."
Mark faces criminal assault and battery on an elder with serious bodily injury ... prosecutors could file more serious charges following the autopsy findings.
