Suicide or Murder?

Deborah Palfrey better known as the "the D.C. Madam" according to reports hanged herself in a storage shed behind her mother's mobile home in a small Gulf Coast city in Tarpon Springs, Fla. Who can ever forget the fear and rumblings in our fair city of Washington, D.C when after Palfrey's indictment she gave volumes of her phone records to ABC news and posted them on the Internet, resulting in public identification of some prominent and powerful clients with family's and careers that were threatened to be destroyed. Remember Palfrey's former employee Brandy Britton, a former college professor who hanged herself in her Howard County home in January 2007 shortly before her scheduled trial on prostitution charges. Is this all coincidental or do we have the making of another Marilyn Monroe conspiracy developing. Were there those among the power elite who found it necessary to find a way to eliminate both women? What If these cult of women who knew the names of those that frequent their enterprise decided to tell all? Obviously their revelation would send shock waves and humiliation through the corridors of power in the political, financial, entertainment and media world.
Should we believe Palfrey when she said, "I sure heck am not going to be going to federal prison for one day, let alone, you know, four to eight years," ABC quoted her as saying recently. Can we reason that this insight from her makes it clear that she was suicidal. Do we trust her mother when she makes it clear that her daughter had "no indication" to end her life and that she did not appear anguished "to the point of committing suicide."
Was this suicide or murder? Should we investigate further?
