Las Vegas police are disputing claims by family members of blues legend BB King that they have launched a homicide investigation into his death.

Two B.B. King heirs accused his two closest aides of poisoning him, but the attorney for King's estate called 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 Associated Press.

Daughters Karen Williams and Patty King alleged 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.

"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 said.

Toney and Johnson each declined to comment on the accusations.

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.

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," Drohobyczer said. She alleged that Toney hastened King's death by "misconduct, or by failing to properly attend to his medical needs."

An autopsy was performed on King on Sunday. 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, Clark County Coroner John Fudenberg said.

Fudenberg issued a statement Monday saying there was no immediate evidence supporting the murder allegations, and Las Vegas police Lt. Ray Steiber told the AP that there was no active homicide investigation.

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.

"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.
