Medical examiners found no evidence to prove claims that blues legend B.B. King was poisoned before he died of natural causes in May, according to autopsy findings released Monday.

King's 11 adult children said that there was foul play involved that made it appear that the blues legend died from Alzheimer's disease and physical conditions that included coronary disease, heart failure and Type 2 diabetes, according to Fox as told by Clark County Coroner John Fudenberg after a series of tests have been done.

King's daughters, Karen Williams and Patty King stated through their attorney Larissa Drohobyczer that the jazz legend's manager, LaVerne Toney, and his personal assistant Myron Johnson, expedited their father's demise. Drohobyczer made no immediate response.

On the other hand, lawyer for King's estate called the claims as defamatory and libelous, and stated that Toney and Johnson are both happy for having the false and fictional allegations made against them by King's children dispelled.

King died May 14 in a home hospice care in Las Vegas. CNN reported that his daughters said that two of their father's associates gave him medication to induce diabetic shock. Initial autopsy reports however, didn't support this.

CNN added the two siblings made their accusations in separate, but identically-worded affidavits.  At that time, an attorney for Toney, one of the accused, said that King's two daughters were trying to get a check.

The allegations of foul play was said to be rooted in contesting for the control of King's asset estimated to be worth millions. Drohobyczer said she thinks it ranges between $5 and $10 million.

The autopsy was performed on May 24, ten days after King died. Fudenberg said "multi-infarct dementia" was the reasonable conclusion. Their tests didn't detect any substances that may have hastened King's death.

Fudenberg added that the finding has officially put the investigation to a close, said Sky News.
