Two of blues legend B.B. King’s 15 children claim the recent death of their father was a murder. The coroner in Las Vegas, Nevada, where King died earlier this month, said his office is taking the accusations “very seriously.”

King died May 14 at the age of 89, reportedly from complications related to the musician’s long battle with diabetes. An autopsy was performed Sunday but it could be eight weeks or more until results are released.

Clark County Coroner John Fudenberg said that, with the unsubstantiated accusations that King was poisoned, his death will now be investigated as a possible homicide, reiterating that his department will conduct “a thorough investigation.” In conjunction with the Las Vegaas Metropolitan Police Department’s Homicide Division, he estimated that the investigation will take at least six to eight weeks.

A spokesman for the police said his department will not open an investigation until which time that the coroner in Clark County has declared that King’s death was from something other than natural causes.”

Two of King’s daughters, Patty King and Karen Williams, provided The Washington Post with affidavits declaring their belief that their father died from poisoning and “was administered foreign substances.” They went further, alleging that the medical care of B.B. King was less than ideal, that he was given an “alleged medication” intended to bring about diabetic shock “since his blood sugar would not be monitored for up to ten days at a time.”

The affidavits, which were submitted to the newspaper by the siblings’ lawyer, Larissa Drohobyczer, concluded their belief that their father was murdered.

B.B. King’s business agent, Patricia Toney, said that the daughters had been making such allegations ever since his death. “What’s new?” she sniffed.

Toney’s defensive reaction comes as Patty King and Karen Williams implicated her directly in their father’s death. Both women stated that they saw Ms. Toney – who apparently had a power of attorney for their father, give “foreign substances and / or medication” to him. These, they claim had been “locked and hidden by Ms. Toney.” This lead them to the conclusion that Toney herself had administered “medications or poisons into” their father’s body.
