While they did not reveal the cause of death, they did say that the musician's body would be released to his family on Friday and that they would report "anything relevant to the investigation" to the authorities who are still investigating Prince's death.
The medical examiner's office notes that the results of their autopsy may take several days and the full toxicology report may take weeks.
Prince's autopsy was performed on Friday by Chief Medical Examiner A. Quinn Strobl, the Midwest Medical Examiner's Office announced on Friday.
The singer's publicist confirmed that he had died on Thursday, April 21, at his Paisley Park compound in Minnesota.
The star had been battling the flu for several weeks and his private plane was forced to make an emergency landing on Friday, April 15, when the 57-year-old singer was rushed to a local hospital in Moline, Illinois.
Prince had been traveling back from what would become his final concert in Atlanta, which took place on April 14. The gig took place after he had to cancel a previous concert the week before due to illness. According to one concert-goer, there was no indication that Prince was ill when he performed on April 14.
"There was a tiny bit of gravel in his voice from time to time, but that was the only indication that he'd felt ill the week before," the concertgoer told PEOPLE. "He left everything on the stage, like he always did."

Immediately after news of Prince's death broke, tributes to the revolutionary musician began to roll in on social media.
The larger-than-life musician – known as much for his over-the-top showmanship as he was for his award-winning music – was born in Minneapolis and developed a love of music from his parents, who were both musicians. His 1984 album, Purple Rain, has long been lauded as one of the greatest albums of all time. He was inducted into the Rock & Roll Hall of Fame in 2004.
