Did Prince die a day before he was to see addiction doctor?

A bombshell report from the Minneapolis Star Tribune reveals new details about the circumstances surrounding Prince's death. According to the report, the music icon died just one day before he was scheduled to see an opioid addiction specialist.

The Star Tribune reports: "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.'"

However, Kornfeld "could not clear his schedule" for an April 21st meeting, so he sent his son to Minnesota, in hopes he could "quickly evaluate his health and devise a treatment plan." But when his son arrived at Paisley Park on the morning of April 21, "Prince's representatives could not find him," the report said.

"The musician's body was found in an elevator a few minutes later -- and it was Andrew Kornfeld who called 911," the report said. Only three people were reportedly inside Prince's Paisley Park compound in Minnesota when he was found dead.

CBS News confirmed that painkillers were found at the scene.

Sources tell CBS News that the Carver County Sheriff's Office contacted the Drug Enforcement Administration about joining the investigation, if the pills are related to his death.

On Tuesday, the Carver County Sheriff's Office released a log of dozens of emergency calls to Prince's Paisley Park home. In June of 2011, the report said "RP," or reporting person, "is concerned about Prince's cocaine habits."

"He advised her last year in Germany that he cannot control his habit and she was advised to report it," the log said.

But officers were unable to investigate since "info is a year old and she did not specify that Prince is in immediate danger."

Prince's autopsy, which will include toxicology results, is pending. Investigators are trying to figure out where Prince got the pills found at his home and who might have provided them.
