B.B. King's Daughter Allege Murder.
COSTELLO: Explosive new accusations in the death of legendary blues singer B.B. King. Two of Kings' daughters filed affidavits over the weekend saying their father was murdered. The 89-year-old B.B. King died earlier this month under hospice care at his home in Las Vegas. King' cause of death is listed as dementia resulting from a series of strokes. But King's daughters claim the singer was poisoned. They say their father's personal assistant and business manager kept King away from the family and gave him medications to induce diabetic shock. A lawyer for the women said this.</s>LARISSA DROHOBYCZER, ATTORNEY FOR B.B. KING'S DAUGHTERS: They didn't see their father die. They didn't see him for a week before he died. They want to know and they want to be at peace. And if everything is on the up and up, fine. They know that and they can go to their grave knowing that their father did die peacefully in his sleep.</s>COSTELLO: Joining me to talk about this, Paul Callan, CNN's legal analyst. So they just want to know everything's on the up and up. They're alleging murder!</s>PAUL CALLAN, CNN LEGAL ANALYST: Well, yes, it's quite shocking. I mean, the attorney obviously drafted this affidavit which essentially says that his business manager and his personal assistant committed murder by poisoning him to death. They just want to find out what happened?</s>COSTELLO: Well, inducing diabetic shock, you would have to give him an extra dose of insulin maybe. They would induce diabetic shock. But poison?</s>CALLAN: Well, there doesn't seem to be anything in the affidavit that indicates a supportable murder case here. But obviously when you make an allegation like this, the coroner is still involved in the investigation. The body is still available. They most certainly will be doing a toxicology run to test this theory as to whether poison was involved.</s>COSTELLO: So the family has the right to do that even though the executor of B.B. King's estate isn't a family member.</s>CALLAN: Well, they have the right to request that the coroner do it. Now, if they want to supersede the rights of the executor of the will, they would have to go into court with a petition to the court asking that the body be separated and that an independent expert be appointed. Now I'm not so sure that they would get it on this affidavit, which is very weak. And of course we would have to see what the coroner had to say. If a toxicology report has been done and it doesn't indicate anything out of the ordinary, I don't think they'll get it. Eleven kids here. He had 15 kids, 11 are still alive, multimillion dollar estate. I suspect this may be the first of many battles among many children for his multimillion dollar estate.</s>COSTELLO: OK, let's go back to the cause of death for just a second, because doctors said he died from a of series of small strokes that were caused by his -- by his having diabetes so many years. He like had Type II diabetes. It was a terrible problem for him all of his life. So why would they put that as the cause of the death if they weren't sure?</s>CALLAN: Well, I mean doctors do -- there's a certain element of speculation about cause of death in the absence of a very detailed autopsy. We don't know enough background to know whether the medical doctors did an autopsy at the hospital, whether the autopsy will be done strictly by the coroner's office. So it's really premature for us to know whether that's based on good medicine or speculation, a little bit of speculation. You know, when someone is 89 or 90 years old, a lot of times they just say, OK, heart attack, diabetes, old age. There's not a lot of investigation that goes into it in the absence of an allegation. But now somebody's saying murder. So I think the D.A. and the police will have to take a look at it.</s>COSTELLO: Paul Callan, thanks so much. I appreciate it.</s>CALLAN: Thank you.</s>COSTELLO: The next hour of NEWSROOM after a break.
