Blues musician B.B. King’s daughters Karen Williams (C) and Patty King (R) cry touching a hearse carrying the remains their father during a processional on May 27, 2015 in Memphis,Tennessee.

*A former personal aide to B.B. King is suing three of his daughters in Las Vegas over allegations that the singer was poisoned and murdered, reports The AP.

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.

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 the 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.
