UPDATE 5/27: The Las Vegas coroner said that preliminary evidence reveals no sign that B.B. King was murdered.

Homicide detectives in Clark County, Nevada, are investigating the death of B.B. King, after King's daughters charged his long-time manager with murdering the blues legend.

Patty King has, in fact, made a series of thus-far-unproven claims against Laverne Toney, who held B.B. King's power of attorney – including an elder-abuse charge just before he died on May 14. Investigations into that allegation, as well as a similar charge from back in November, found no evidence of wrong doing.

"They’ve been making allegations all along," Toney told the Associated Press. "What’s new?" Toney's lawyer has similarly deemed this new charge "ridiculous."

Patty King and her sister Karen Williams filed identically worded affidavits stating their belief that B.B. King "was poisoned and that he was administered foreign substances. I believe my father was murdered.” They are blaming both Toney and personal assistant Myron Johnson.

Clark County coroner John Fudenberg performed an autopsy Sunday on B.B. King's embalmed body. Toxicological results won't be available, however, for as many as eight weeks. Fudenberg confirmed that King's body has now been returned to a mortuary in Las Vegas. The latest investigation was confirmed by Lt. Ray Steiber of the Las Vegas police department.

Initially, B.B. King's death was linked to the 89-year-old's lengthy, and very public, battle with Type 2 diabetes. A memorial service was held in Las Vegas late last week.

A lawyer representing Patty King and Karen Williams – as well as other heirs including B.B. King's daughters Michelle King, Barbara King Winfree and Claudette King Robinson – is also challenging King's will. Attorney Larissa Drohobyczer claims Toney misappropriated millions of dollars, and is thus unqualified to serve as executor of the King estate.
