May 18 (UPI) -- Soundgarden frontman Chris Cornell died Wednesday night. He was 52 years old.
The Wayne County Medical Examiner's Office told E! News in a statement, "The cause of death has been determined as hanging by suicide. A full autopsy report has not yet been completed."
The singer died in Detroit where the band performed on May 17.
Cornell, born in 1964, formed Seattle grunge band Soundgarden in 1984. The band released their first single "Hunted Down" on Subpop in 1987. Their most popular songs, "Black Hole Sun" and "Spoonman," both won Grammys. Soundgarden, which includes guitarist Kim Thayil, bassist Ben Shepherd and drummer Matt Cameron, disbanded in 1997, but reunited in 2010. They have been performing together ever since.
The singer helped form the band Temple of the Dog in 1990 with members of Pearl Jam in tribute to late frontman of Mother Love Bone Andrew Wood. In the early 2000s, Cornell started the group Audioslave, which featured members of Rage Against the Machine. Their song, "Like a Stone," was nominated for a Grammy. The band broke up in 2007.
Cornell also released five solo albums during his time with Soundgarden including "Euphoria Morning." His song "Seasons" was on the soundtrack of "Singles," the Cameron Crowe film which he also appeared in.
In 2006, his song "You Know My Name" for the film Casino Royale won a Golden Globe award.
Rage Against the Machine posted a tweet honoring Cornell when news broke early Thursday morning.
