B.B. King's Daughters Allege That Their Father Was Poisoned Before His Death

Two of B.B. King's daughters want their father's death investigated much further.

According to new court documents obtained by E! News, Karen Williams and Patty King allege B.B.'s business manager Laverne Toney and his personal assistant poisoned the legendary singer.

"I believe my father was poisoned and that he was administrated foreign substances to induce his premature death," the daughters wrote in separate but identical affidavits. "[I] request a formal investigation into this matter."

Toney, who has been named the executor of B.B.'s estate, responded to the new allegations by sharing, "They've been making allegations all along. What's new?" Furthermore, an attorney for B.B.'s estate told reporters that the daughters' allegations are "ridiculous."

"I hope they have a factual basis that they can demonstrate for their defamatory and libelous allegations," Brent Bryson said in a statement. "This is extremely disrespectful to B.B. King. He did not want invasive medical procedures. He made the decision to return home for hospice care instead of staying in a hospital. These unfounded allegations have caused Mr. King to undergo an autopsy, which is exactly what he didn't want."

A spokesperson for the Clark County Coroner's office confirmed to E! News that there is a "pending investigation" into the singer's death and an examination on B.B. was conducted Sunday. The Las Vegas Metropolitan Police Department, however, told NBC News that they are not moving forward with any investigation at this time.

King passed away May 14 at his home in Las Vegas. He was 89. His attorney said the blues singer died peacefully in his sleep.

The 15-time Grammy winner, who released more than 50 albums during his lifetime, continued to perform shows for fans well into his 80s.
