LAS VEGAS –Two of B.B. King heirs who’ve been most outspoken about the blues legend’s final days, have accused King’s two closest aides of poisoning him.

Daughters Karen Williams and Patty King alleged in documents provided by their lawyer to The Associated Press that King’s Business Manager, LaVerne Toney, and his personal assistant, Myron Johnson, killed their father.

Clark County Coroner John Fudenberg  said Monday that an autopsy was performed Sunday on King’s embalmed body, and test results would take up to eight weeks.

Las Vegas Police Lt. Ray Steiber confirmed that homicide detectives are investigating.

Toney and Johnson each declined to comment.

The coroner said King’s body has been returned to a mortuary, and the investigation shouldn’t delay planned memorials this week in Memphis, Tennessee, and Indianola, Mississippi.
