B.B. King's death

As blues' pre-eminent guitarist, he was larger than life - and it appears, after his death on May 14, B.B. King won't be going quietly, following allegations that his death may have been hastened.

Two of his daughters - Karen Williams and Patty King - made the spectacular claims in the wake of the 89-year-old's death, alleging he was poisoned by his business manager LaVerne Toney and his personal assistant Myron Johnson.

According to news agency AFP, the daughters lodged separate but reportedly identical affidavits, stating: "I believe my father was poisoned and that he was administrated foreign substances to induce his premature death."

King died in Las Vegas after reportedly experiencing complications from Type II diabetes, a disease from which he had suffered for two decades. However, his last days were overshadowed by a dispute between King's family and manager, with a court in Las Vegas dismissing Karen Williams' attempts to replace Toney as her father's guardian.

According to reports in the UK's "Guardian Newspaper," attorneys for King's estate have rubbished the poisoning claims and police have responded that there is currently no active homicide investigation. The newspaper also reported claims that King's friends were prevented from visiting him in his final days and that significant sums of money were withdrawn from his bank account.

Born into a life of poverty on the cotton plantations of Mississippi, Riley B. King went onto become the world's leading ambassador of blues music, admired as much for his startling guitar skills as his grueling work ethic, which saw him play a show almost every night throughout his active career.

King's estate could be worth tens of millions of dollars, according to official court documents lodged by lawyers representing King's heirs.

An autopsy was undertaken on Sunday, although official test results could take up to eight weeks, according to an announcement on Twitter from the Clark County, Nevada, coroner's office.
