Kafele H. Sims, 32
Sims was on his second tour of duty in Iraq when he passed away. Army officials said his death did not occur during combat and that the cause remains under investigation. His wife said she has been told that there were no obvious signs of trauma to her husband's body and that homicide and suicide have been ruled out. Sims was due to wrap up his tour and return home to his wife and three young children in Arizona about two weeks after he died.
