LAS VEGAS » Two B.B. King heirs who’ve been most outspoken about the blues legend’s care in his final days are accusing King’s two closest aides of poisoning him, but the attorney for King’s estate is calling the claims ridiculous.

Three doctors determined that King was appropriately cared-for, and King received 24-hour care and monitoring by medical professionals “up until the time that he peacefully passed away in his sleep,” attorney Brent Bryson told the AP on Monday.

Daughters Karen Williams and Patty King allege that family members were prevented from visiting while King’s business manager, LaVerne Toney, and his personal assistant, Myron Johnson, hastened their father’s death.

Toney is named in King’s will as executor of an estate that, according to court documents filed by lawyers for some of King’s heirs, could total tens of millions of dollars.

Johnson was at B.B. King’s bedside when he died May 14 in hospice care at home in Las Vegas at age 89. No family members were present.

“I believe my father was poisoned and that he was administered foreign substances,” Patty King and Williams say in identically worded sections of affidavits provided to The Associated Press by their lawyer, Larissa Drohobyczer.

“I believe my father was murdered,” they say.

Toney and Johnson each declined to comment on the accusations.

“They’ve been making allegations all along. What’s new?” said Toney, who worked for King for 39 years and had power-of-attorney over his affairs.

A week before King’s death, a judge in Las Vegas dismissed a request from Williams to take over as King’s guardian.

An April 29 petition alleged that Toney had blocked King’s friends from visiting him and had put her family members on King’s payroll. It also alleged that large sums of money had disappeared from King’s bank accounts.

But Clark County Family Court Hearing Master Jon Norheim said on May 7 that police and social services investigations in October and April uncovered no reason to take power-of-attorney from Toney.

Williams, Patty King and another daughter— Rita Washington — vowed to keep fighting.

“We lost the battle, but we haven’t lost the war,” Williams said then.

This week’s allegations come days after a public viewing in Las Vegas drew more than 1,000 fans and mourners and a weekend family-and-friends memorial drew 350. A Beale Street procession and memorial are scheduled Wednesday in Memphis, Tennessee, followed by a Friday viewing and Saturday burial in King’s hometown of Indianola, Mississippi.

Clark County Coroner John Fudenberg said Monday the investigation shouldn’t delay King’s final trip home to the Mississippi Delta.

Fudenberg said an autopsy was performed Sunday and King’s body was then returned to a Las Vegas mortuary. Test results will take up to eight weeks to obtain, and shouldn’t be affected by the fact that King’s body had been embalmed, he said.

“This is extremely disrespectful to B.B. King,” Bryson said on Monday. “He did not want invasive medical procedures. He made the decision to return home for hospice care instead of staying in a hospital. These unfounded allegations have caused Mr. King to undergo an autopsy, which is exactly what he didn’t want.”

Las Vegas police homicide detectives are investigating, Lt. Ray Steiber said Monday. He declined to provide details.

Drohobyczer said she represents Williams, Patty King and most of King’s nine other adult children and heirs.

“The family is sticking together … to oust Ms. Toney based on her illegal conduct, conflicts of interest and self-dealing,” she said. She alleged that Toney hastened King’s death by “misconduct, or by failing to properly attend to his medical needs.”

An affidavit from Patty King, who used to live at King’s home, says she saw Johnson administer to King two drops of an unknown substance on his tongue during evenings for several months before his death, and that Toney never told her what the substance was.

Bryson called Drohobyczer’s claims ridiculous.

“I hope they have a factual basis that they can demonstrate for their defamatory and libelous allegations,” he said.
