Developments are emerging along two tracks: cause of death and what to do with his vast estate. Here's the latest:
First, authorities found prescription opioid medication on Prince and in his Minnesota home during the investigation of his death. So far, investigators have not found evidence that Prince had a valid prescription for the painkillers, leading the U.S. Attorney's Office and the U.S. Drug Enforcement Administration to launch a formal investigation into their source.
Then, it came to light that Prince's team sought help from Dr. Howard Kornfeld, an eminent opioid addiction specialist, the day before he died. Kornfield sent his son, Andrew, to Minnesota. William Mauzy, a lawyer for Andrew Kornfeld, said the plan was to help evaluate Prince's health and encourage him to enter treatment for pain management and potential addiction issues.
By the time Kornfeld arrived at the singer's Paisley Park complex on the morning of April 21, it was too late.
