A medical examiner has determined that Soundgarden singer Chris Cornell killed himself by hanging in a Detroit hotel room following a concert.

Cornell died nearly seven hours after tweeting that he was in Detroit for a performance, according to his representative.

Cornell was 52 and gained fame as the lead singer of Soundgarden, Temple of the Dog, and later Audioslave.

Two Detroit newspapers had earlier cited a police spokesman saying Cornell was found with "a band around his neck."

A different Detroit Police spokesman, Michael Woody, told The Associated Press Thursday that he could not confirm that Cornell died with a band around his neck.

Brian Bumbery called the death "sudden and unexpected" and said his wife and family were shocked by it. The statement said the family would be working closely with the medical examiner to determine the cause and asked for privacy.

The Associated Press and CBS Detroit contributed to this story.
