Patty King, who clashed with the guitar great's manager, LaVerne Toney, over her father's welfare in the weeks before his death in May (15), told the authorities she hoped the paperwork would prove her father's finances and health were mismanaged.

However, Brent Bryson, the attorney for B.B. King's estate, told the judge overseeing the case that Patty was simply fishing for evidence to support false claims the musician's longtime business manager and power-of-attorney, Toney, stole from her client.

He also reiterated King died of natural causes, and Toney, who is now the executor of his estate, is carrying out his last wishes to keep his private affairs private.

Patty King accused Toney of not having her father's wellbeing at the top of her priority list shortly before his death, but three doctors, including King's personal physician, ruled that he was being properly cared for.

An autopsy carried out by the Clark County coroner found no evidence to prove King had been poisoned - allegations made by Patty and her sister, Karen Williams.

King died of Alzheimer's disease, plus physical conditions including coronary disease, heart failure and the effects of Type 2 diabetes, the coroner found.

Outside court on Friday (21Aug15), Patty King and her lawyer vowed they would keep fighting for the blues legend's medical records.
