Last week, the world of music mourned as it lost one of the all time greats. B.B. King passed away at the age of 89, and although most people assumed he had died of natural causes, his two daughters are suggesting otherwise.

Karen Williams and Patty King claim their famous father was "poisoned and that he was administered foreign substances." "Our father was murdered," they said, blaming his manager LaVerne Toney and personal assistant Myron Johnson.

The case is now being investigated by Las Vegas police, but results aren't expected for another eight weeks.
