(RNN) - The chief medical examiner for the Midwest Medical Examiner's Office completed an autopsy on Prince, and his body will be released to his family.
The four-hour procedure was finished Friday around 1 p.m. central time, but full toxicology results will not be ready for a few weeks. The process includes gathering medical and family history and other information that could be relevant to his death, the medical examiner's office said in a release.
The singer and musician was found dead in his Paisley Park compound in Minnesota on Thursday. He was 57.
Police found the music legend unresponsive in an elevator. Paramedics performed CPR but were unable to resuscitate him.
He died less than a week after his plane made an emergency landing in Illinois after a concert in Atlanta. His representatives said he was hospitalized for a short time and had been battling the flu for several weeks.
However, on April 16, Prince hosted a concert and dance party at Paisley Park. Attendees thought the singer looked fine and said he gave a good concert.
Prince was born in Minneapolis in 1958. The son of a jazz musician and singer, he learned guitar, piano and drums by the age of 14.
He released his first album, For You, in 1978. He went on to win seven Grammys during his prolific career, writing unforgettable hits like Purple Rain, Little Red Corvette and 1999. He won an Oscar for the original score to the film Purple Rain and sold more than 100 million albums, ranking him along the best-selling artists of all time.
He also penned and produced numerous top hits for other notable performers, including Sinead O'Connor, The Bangles, Celine Dion, MC Hammer and others.
