Blues legend BB King has been found to have died from natural causes stemming primarily from Alzheimer's Disease.
The ruling, by medical officials in the state of Nevada, puts to rest accusations by his two daughters that he was murdered.
King, known for his hits Lucille, Sweet Black Angel and Rock Me Baby, died in his sleep in Las Vegas in May, aged 89.
His daughters alleged he was poisoned by longtime associates and called for a homicide investigation.
But, in a final report, Clark County Coroner John Fudenberg said the musician had a number of health concerns and he was satisfied he died of natural causes.
"At this point we can say with confidence that Mr King died of natural causes," he said.
"Our condolences go out to the family and many friends of Mr King, and we hope this determination brings them some measure of closure."
Born in Mississippi, King began performing in the 1940s and was inducted into the Blues Foundation Hall of Fame and the Rock and Roll Hall of Fame.
He was placed in hospice care after being hospitalised in April from complications related to diabetes. He died shortly afterwards, on 14 May.
Hundreds of mourners gathered for his funeral in Memphis, Tennessee, bidding him a musical farewell.
