Several prescription drugs were found in Chris Cornell's system, but they played no active role in his suicide last month, a toxicology report concludes. "It is my opinion that death was caused by hanging," the Wayne County assistant medical examiner said. "Based on the circumstances surrounding this death and the autopsy findings, the manner of death is suicide." Following the release of the report, Cornell's widow said that the singer had not been an active drug user for more than a decade. "Many of us who know Chris well, noticed that he wasn't himself during his final hours and that something was very off," Vicky Karayiannis said Friday. "After so many years of sobriety, this moment of terrible judgement seems to have completely impaired and altered his state of mind."
