Chris Cornell's widow disputed an official finding that her rocker husband died by suicide and revealed Friday that he had "taken an extra Ativan or two" shortly before he was found unresponsive. Vicky Cornell became worried when her husband, the frontman for Soundgarden and Audioslave, told her by phone about his dose of the prescription sedative, which can be used to treat anxiety. They spoke shortly after Chris Cornell performed a concert Wednesday night in Detroit, she said; he was found around midnight Thursday. "When we spoke after the show, I noticed he was slurring his words; he was different," Vicky Cornell said. "When he told me he may have taken an extra Ativan or two, I contacted security and asked that they check on him." Cornell does not believe her husband "intentionally" took his own life
