Two of B.B. King's daughters are alleging that the blues legend was poisoned to death by his closest associates. But the coroner says preliminary autopsy results don't support that contention.

King's daughters, Patty King and Karen Williams, made the accusations in separate, but identically worded, affidavits filed over the weekend. "I believe my father was poisoned and that he was administered foreign substances to induce his premature death," they said in their affidavits. "I believe my father was murdered." King died May 14 in home hospice care in Las Vegas at age 89.
