Blues legend BB King died in May, and you may recall that things got pretty ugly very quickly after his death when two of his daughters contested his will and accused his manager and personal assistant of negligence.

In fact, Patti King and Karen Williams said in a sworn affidavit that they believed that their father was poisoned by his aides and "administered foreign substances" which led to his death.

An autopsy was performed, and the results have just recently come back from the coroner, who said that there was no evidence of poising.

Las Vegas coroner John Fudenberg said that the cause of the 89-year-old musician's death was Alzheimer's disease, coupled with other physical conditions.

The ruling means that the investigative case brought by King and Williams has now been closed.
