MINNEAPOLIS-- The audio from the call made when Prince's plane made an emergency landing six days before his death has now been released, CBS Minnesota reported.
After returning from a show in Atlanta on April 14, Prince's private jet unexpectedly landed in Illinois on its way back to Minnesota, and the singer was rushed to the hospital.
Airport officials told CBS Minnesota emergency personnel responded to an "unresponsive passenger," who was then taken to a local hospital. Prince's publicist later said he was treated for flu-like symptoms.
The full audio can be heard here:
Prince was found unresponsive in an elevator Thursday at Paisley Park, and an autopsy was done Friday. But authorities have not released a cause of death and have said results could take days or weeks.
The publicist's brief statement repeated that the cause of Prince's death was unknown, and said autopsy results wouldn't be received for at least four weeks.
Prince was last seen alive by an acquaintance who dropped him off at Paisley Park at 8 p.m. Wednesday, according to Carver County Sheriff Jim Olson.
The "Purple Rain" star, born Prince Rogers Nelson, was found by staff members who went to the compound in Chanhassen, about 20 miles outside Minneapolis, the next morning when they couldn't reach him by phone.
Emergency crews who answered the 911 call could not revive Prince, the sheriff said.
Some of Prince's "most beloved" family, friends and musicians celebrated his life in a small, private service on Saturday after his remains had been cremated.
His publicist Yvette Noel-Schure said in a statement that the 57-year-old music superstar's family and friends gathered "in a private, beautiful ceremony" to say a loving goodbye.
