Chris Cornell, vocalist of Audioslave, Soundgarden, and Temple of the Dog, died on Wednesday night at the age of 52.

Rolling Stone reports that Detroit police are investigating the death as a possible suicide. An official cause of death via medical examiner has not yet been produced, and is expected to be released on Thursday afternoon.

Cornell's death was "sudden and unexpected," according to a statement released by his representative Brian Bumbery.

Hours before he died, Cornell played a concert in Detroit with Soundgarden.

Cornell was a father of three; a daughter born in 2000, another daughter born in 2004, and a son born in 2005.
