Timeline of Prince's final days

April 14: Prince returns to Atlanta and performs two concerts.

April 15: While returning to Minneapolis, Prince's private plane makes an emergency landing in Moline, Ill., about 1:15 a.m. after he overdoses on opioids, according to a source. A bodyguard carries Prince, who is unconscious, from the plane. Emergency responders administer a shot of Narcan, an opioid antidote, and take him to the hospital. He does not stay, however, and returns to Minneapolis later that morning.

April 16: Prince invites guests to a dance party at Paisley Park, where he plays "Chopsticks" on his new purple piano and shows off a metallic purple guitar. In a brief speech, he tells his audience to "Wait a few days" before offering any prayers.

April 19: Prince attends a concert at the Dakota in Minneapolis. It is the last time he is seen in public.

April 20: Schulenberg treats Prince again. That night, a Prince representative in California contacts Dr. Howard Kornfeld, a California addiction specialist, and asks him to intervene and help get the megastar off prescription painkillers. Kornfeld cannot clear his schedule to fly to Minnesota immediately, so he sends his son, Andrew, on an overnight flight, with a drug used to help with opioid addiction treatment.

April 21: Shortly after arriving at Paisley Park about 9:30 a.m., Andrew Kornfeld and two Prince staffers — longtime friend Kirk Johnson and personal assistant Meron Bekure — find Prince unconscious in an elevator. Kornfeld calls 911 at 9:43 a.m. Emergency responders arrive five minutes later and pronounce him dead at 10:07 a.m. Schulenberg arrives at some point before police show up and tells an investigator that he was there to deliver test results to Prince, according to a search warrant. He also tells the investigator that he had prescribed medications to be filled at a Walgreens pharmacy.

April 23: Prince is cremated and a private funeral service is held at Paisley Park.
