A former personal aide to B.B. King is suing three of the late blues legend's daughters in Las Vegas over allegations that King was poisoned and murdered.
Myron Johnson accuses Karen Williams, Patty King and Rita Washington of defamation, slander, libel and conspiracy in the lawsuit filed Thursday in Clark County District Court.
Patty King declined to comment, and Williams didn't immediately respond to messages.
Washington called the lawsuit a product of a dispute between Williams and Johnson, who are half-brother and sister.
Johnson's lawyer, Brent Bryson, is also lawyer for King's estate.
Bryson points to police and county elder care agency investigations and affidavits from three doctors who found no evidence that B.B. King was abused.
The Clark County coroner ruled King's May 14 death was from natural causes.
