Questions Surrounding Luther Vandross' Death?

It appears that there are now some questions emerging as to the cause of Luther's death. I don't have much information on this, but according to a FOX News report, Luther's manager Carmen Romano claims that is was a constant struggle between her and Vandross' mother Mary Ida Vandross (pictured) and sister. I am not sure how valid this claim is, but the FOX News article suggests that more details are to come in the following days. I hope that these claims are not true, and more importantly I hope that the world only give Luther the respect that he deserves during this time of mourning. I have seen Luther's mother in several interviews since his stroke two years ago, and I must say she seemed very passionate about doing everything she could to see that Luther recovered. In addition, I have also heard her, and Luther allude to the fact that all of his siblings were deceased already, which causes me to further question the FOX News article.
