Los Angeles: Legendary blues guitarist B.B. King, who died aged 89, was poisoned, according to two of the music great's heirs. King's daughters, Patty King and Karen Williams, made the accusations in separate, but identically worded affidavits filed over the weekend, reports CNN.

"I believe my father was poisoned and that he was administered foreign substances to induce his premature death. I believe my father was murdered," they said in their affidavits.
