Prince was found dead at his Minnesota compound just one day before he was supposed to meet a doctor to help him with his alleged painkiller addiction, according to a published report.
Lawyer William Mauzy told the Star Tribune of Minneapolis that representatives for Prince called Howard Kornfeld, a northern California doctor who specialises in opioid-addiction treatment, on the night of April 20 because the musician "was dealing with a grave medical emergency".
The following morning, Prince's body was discovered in a lift at his Paisley Park complex.
Kornfeld, the medical director at Recovery Without Walls, could not meet Prince until April 22, so he sent his son and associate, Andrew Kornfeld, to fill Prince in on the medical care that the clinic could offer him, their family's attorney told the Star Tribune.
"The plan was to quickly evaluate his health and devise a treatment plan," Mauzy, who is working with the Kornfelds, told the newspaper. "The doctor was planning on a lifesaving mission."
