Two of BB King's daughters are accusing two of his closest aides of poisoning him.

The lawyer for King's estate says that's ridiculous and points out three doctors determined that King was appropriately cared-for.

Daughters Karen Williams and Patty King allege that family members were prevented from visiting while King's business manager and his personal assistant hastened their father's death.

Blues legend BB King died on May 14 in hospice care at home in Las Vegas, aged 89.
