A sudden death is always tragic. It is unexpected and because of that can cause more trauma than an expected death. Noone is truly prepared to see a loved one pass away but sudden death can cause many issues for the grieving. In particular, the nature of the death, as well as unresolved issues due to the sudden passing, can all cause more intense grief reactions.
