Donda West, 58, died on November 10, one day after Dr. Jan Adams performed a tummy tuck, breast reduction and liposuction surgery.

According to a Los Angeles County Coroner’s Office preliminary report, drugs were not mentioned as a cause of death, instead citing surgery or anesthesia as the primary cause, the Times reports. An investigation is ongoing.

Adams told the Times that he knows "exactly what happened to her" but refuses to comment until a final report is issued from the coroner's office.

In the Times article, Adams discusses several of the malpractice suits that had been filed against him, calling two of them major while dismissing the remaining suits as ‘nuisance’ suits.
