Chris Cornell of Soundgarden has died shortly after a perfomance in Detroit. A spokesperson for Detroit Police confirmed that they received a call just after 11:00PM CST.

"He was found on the bathroom floor, our medical unit were called and he was pronounced dead on scene," a spokesperson said.

"A family friend went to go check on him and observed him on the bathroom floor. The body was transferred to the medical examiner's office and the cause of death will be determined."

In a statement, Cornell's representative Brian Bumbery said his death was "sudden and unexpected". It also said the family would be working closely with the medical examiner to determine the cause and asked for privacy.

It has been rumored that the death is being investigated as a suicide. But just before the Wednesday night show Chris posted to his Twitter account seeming upbeat. The hastag #nomorebullshit does appear in the tweet however which makes one wonder what that's all about. 

UPDATE: According to an AP report, a medical examiner has determined Chris Cornell committed suicide by hanging after the Detroit show. No further details are available as of yet. Check back here for updates on this developing story.

UPDATE 2: Soundgarden was the scheduled headliner for Pointfest on Saturday in Maryland Heights, Missouri. In addition to Soundgarden, Pointfest was to feature Stone Sour, Pierce the Veil, Greek Fire and other bands.

Soundgarden was scheduled to headline Friday's Rock on the Range, a three-day concert in Columbus, Ohio. According to the Columbus Dispatch, Rock on the Range will go ahead without Soundgarden.

UPDATE 3: Cornell's wife Vicky spoke to her husband via phone just before he died and said he was slurring his words. He also admitted to possibly taking 1 or two extra Ativan which is medication Chris took for anxiety. Ativan is a medication often used for recovering addicts. Mrs. Cornell believes the overdose of drugs altered Chris's mental faculties and believes they are the cause of her husband's death. Mrs. Cornell went on to say she was "disturbed at inferences that Chris knowingly and intentionally took his life."
