Chris Cornell reportedly had track marks visible on his arm when is body was found, sources close to the investigation told TMZ. Cornell's family has denied that he "intentionally and knowingly" committed suicide, stating that he had taken more than his recommended dose of an anxiety medication, Ativan. The TMZ source said the track marks were "obvious" on Cornell's arm. The Soundgarden frontman suffered from substance abuse problems early in his career and checked into rehab in 2002, eventually sobering up by 2006. It is unclear if Cornell turned to drugs prior to that night in Detroit, but friend of the rocker said that he appeared to be high during the performance. "Chris was out of character from note 1 of the show," said tour manager and house engineer Ted Keedick.
