Soundgarden frontman Chris Cornell died of suicide by hanging, the Wayne County Medical Examiner's Office said on Thursday.
Cornell, 52, was found dead in his Detroit hotel bathroom on Wednesday night after playing a concert in the city with the grunge band.
“The cause of death has been determined as hanging by suicide. A full autopsy report has not yet been completed,” the Medical Examiner’s Office said in a statement after conducting an initial autopsy.
Cornell's publicist Brian Bumbery said earlier that the singer's death was “sudden and unexpected.”
Detroit police spokesman Dan Donakowski said that officers were called to Cornell's hotel around midnight by a friend of the musician and found Cornell "laying in his bathroom, unresponsive and he had passed away."
“What I look forward to the most -- because I tour so much, especially the last couple of years, by myself -- is the camaraderie. It’s what we missed when we weren’t a band,” Cornell had posted on Facebook on Tuesday. The band had been in the middle of a US tour.
Soundgarden was one of the leading bands in the grunge music movement in the 1980s and '90s, releasing albums such as “Badmotorfinger” and the Grammy-winning “Superunknown,” which brought the band mainstream music scene success.
Cornell had spoken openly in interviews of his struggles with drugs as a teenager, and later with alcohol. But he said in 2007 that he had been sober since checking himself into rehab in 2002. He also spoke of periods of depression and agoraphobia.
Soundgarden broke up in 1997 and Cornell in 2001 joined members of Rage Against The Machine to form Audioslave, which earned acclaim with its self-titled album.
Soundgarden reunited in 2010 and embarked on the current US tour in April.
Cornell also had an extensive solo career as a singer, guitarist, composer and lyricist and worked with various other musicians over three decades in the music business.
Cornell was active primarily through the 90s and the early 2000s. He is famed for his near four-octave vocal range.
In 2011, Cornell was ranked 9th in the list of "Best Lead Singers of All Time" by Rolling Stone. He also bagged the 12th spot in MTV's "22 Greatest Voices in Music"
