Words can not express such a deep sadness in that man's heart. "Tears in Heaven" was maybe the only way this dad found to express the sorrow and pain in his heart. People from all around the world are just shocked to hear the news. This is a terrible tragedy. We all send our deepest condolences to all the families that lost any of their loved relatives. Just a few words of hope, as the song goes: " Beyond the door there's peace, I'm sure. And I know, there'll be no more tears in heaven".
