According to the Minneapolis Star-Tribune, Prince died the day before he was to meet with a California physician who specializes in opioid addiction:
Dr. Howard Kornfeld, a national authority on opioid addiction treatment, was called by Prince representatives the night of April 20 because Prince “was dealing with a grave medical emergency,” said William Mauzy, a prominent Minneapolis attorney working with the Kornfeld family.
Kornfeld, who runs Recovery Without Walls in Mill Valley, Calif., could not clear his schedule to meet with Prince the next day, April 21, but he planned to fly out the following day.
So he sent his son, Andrew Kornfeld, who works with him, to Minnesota, with plans for him to go to Paisley Park to explain how the confidential treatment would work, Mauzy said…
When Andrew Kornfeld arrived at Paisley Park at 9:30 a.m. Thursday, Prince’s representatives could not find him, Mauzy said. Andrew Kornfeld was one of three people at Paisley Park when the musician’s body was found in an elevator a few minutes later — and it was Andrew Kornfeld who called 911
