It was an intervention that never happened, and it featured two stars: Prince, an adored music icon, and buprenorphine, an obscure drug hailed as a revolutionary tool to fight opioid addiction. 

Prince died before the first scene, when a drug-addiction consultant, a physician and Prince's associates converged on the star's Paisley Park home near Minneapolis, based on official accounts. The plot twist? The consultant, Andrew Kornfeld of the Recovery Without Walls clinic in Mill Valley, Calif., was carrying a small amount of buprenorphine. Nicknamed "bupe," it is also known by several commercial names including Suboxone. 

Dr. Howard Kornfeld, the founder of the Recovery Without Walls clinic (and Andrew's father) is a leading proponent of the drug as a means of curbing opioid addiction. Dr. Kornfeld and his son declined to be interviewed.

But their attorney, William Mauzy, told reporters following Prince's April 21 death that Andrew Kornfeld had flown to Minneapolis in hopes of encouraging Prince to check himself into the Mill Valley rehabilitation center and that the buprenorphine he was carrying was intended to be turned over to a Minneapolis physician to be administered to the late pop star. According to Mauzy, the medication was not administered and was later taken into possession by sheriff's investigators. 

Authorities have not released Prince's cause of death, and an autopsy report is pending. But an attorney who once represented Prince's deceased half-siblings, Duane and Lorna Nelson, has claimed that Prince was addicted to Percocet, a popular opioid used to treat pain.

The lawyer, Mike Padden, told The Times that the Nelsons asked him to speak on their behalf "to let people know the truth about his situation" in case Prince died — except they died first.
