I don't know ...
But if you want to get a person related to an event (primary role or 
not), you may try Utils.get_referents(handle, db, primary_objects):

def get_referents(handle, db, primary_objects):
     """ Find objects that refer to an object.

     This function is the base for other get_<object>_referents finctions.

     """
     # Use one pass through the reference map to grab all the references
     object_list = [item for item in db.find_backlink_handles(handle)]

     # Then form the object-specific lists
     the_lists = ()

     for primary in primary_objects:
         primary_list = [item[1] for item in object_list if item[0] == 
primary]
         the_lists = the_lists + (primary_list, )

     return the_lists


Note: seems there is a typo on description !
