Step mom committed suicide

Last night my dad cam home from work and found that my stepmom had hung herself. Completely out of the blue and unexpected. What can i do for my dad? I feel helpless. I've never been in this situation. Never had anyone i know commit suicide so I don't even know what to do. She was the happiest most cheerful person. I don't understand. I know my dad blames himself.
