Investigation of Whitney's Death

Nancy Grace is asking what caused the tragic death of singing legend Whitney Houston. Things don't seem or sound right to me. Everybody has their own story. There are people that want to say that Whitney killed herself. It seemed as if Whitney was crying out for help although her lips had been saying it was her fault about the drugs. It seemed as if some people were really not her friends. It seems as if no one was watching Whitney like they should have been, and she should not have been out partying. Things were going alright at first from the way it looked and then all over a sudden there is a turning point. Whitney is dead.
