Nevada officials said Monday they will investigate the death of B.B. King as a possible homicide after two of the blues guitarist’s daughters accused his aides of poisoning him. Clark County Coroner John Fudenberg said authorities are investigating the unsubstantiated claims and coordinating with Las Vegas police, but results may take at least six to eight weeks. However, a police spokesman told NBC News that authorities will not launch an investigation until the coroner “determines Mr. King’s death to be from other than natural causes.” Patty King and Karen Williams allege their father, who died May 14, was poisoned. Patricia Toney, King’s longtime business agent, who has power-of-attorney over his estate, dismissed the claims as ridiculous.
