This is sad.

Chris Cornell's cause of death has been revealed, and the rocker died from suicide by hanging, the Wayne County Medical Examiner's Office announced today. A full autopsy and toxicology report are still pending.

The Soundgarden frontman, 52, was found in the bathroom of the MGM hotel after a gig at the Fox Theatre in Detroit early Thursday morning.

His wife Vicky didn't initially believe he committed suicide, as he showed no signs of depression and was very dedicated to his three kids. The musician struggled with substance abuse for decades, and many wonder if he recently fell off the wagon.

What a tragic loss.
