Rocker Chris Cornell, famous lead singer of Soundgarden and Audioslave, died on tour at the age of 52.

Cornell’s wife in a statement says he may have taken “an extra Ativan or two” before his death

Chris Cornell’s family says the Soundgarden singer was taking a prescription anti-anxiety  medicine, which may have played a role in his death in a Detroit hotel room after a concert Wednesday night.

The Wayne  County Medical Examiner’s Office on Thursday ruled the 52-year-old rocker’s death as a suicide by hanging, but the family says he was on the prescription drug Ativan, which may have played a role.

Cornell’s wife, Vicky, said in a statement released by the family to the Associated Press that when she spoke to him on Wednesday after the group’s show at the Fox Theatre, he may have taken “an extra Ativan or two’’ and was slurring his words.

According to reports, Cornell’s wife became concerned and called a family friend who forced open the hotel room door at the MGM Grand Detroit and found Cornell unresponsive in the bathroom.

“What happened is inexplicable, and I am hopeful that further medical reports will provide additional details,” Vicky Cornell said. “I know that he loved our children and he would not hurt them by intentionally taking his own life.”

In a statement issued through attorney Kirk Pasich, the family said that until the toxicology tests are completed, they can’t be sure what led to the singer-songwriter’s death or if any substance was involved. Pasich told the AP that the anti-anxiety drug has various side effects.
