Everything happened quite fast, so if there were some cameras and journalists sent, all they saw after their arrival was burning island washed away by huge waves. To protect the children and their privacy, all three surviving adults refused interviews and all that media mess, so their stories--or the wife's story, because I assumed that the legend was born after listening to her describing the events--were passed between people the traditional way, without media and technology.
