Chris Cornell's family thinks medication may have played part in suicide

"He was 'slurring his words; he was different,' his wife said.

The family attorney couldn’t verify if the drug Cornell’s wife said the singer took was Ativan or its generic version, lorazepam.

The medications belong to the class of drugs called benzodiazepines. A review of research by the National Center for Biotechnology Information concluded that in the majority of studies in a controlled environment, the risks for attempting suicide went up for those using benzodiazepines like Ativan and lorazepam, coupled with a pre-existing condition of depression.

After news broke early Thursday of the rocker's death at the age of 52, the Wayne County Medical Examiner's Office determined that "the "cause of death [was] hanging by suicide."

She said that later, after the show, he was "slurring his words; he was different," when she spoke to him. She said she wants to wait on the results of toxicology tests before drawing any conclusions.

"When he told me he may have taken an extra Ativan or two, I contacted security and asked that they check on him," she said. "What happened is inexplicable, and I am hopeful that further medical reports will provide additional details. I know that he loved our children and he would not hurt them by intentionally taking his own life."

"Chris's death is a loss that escapes words and has created an emptiness in my heart that will never be filled. As everyone who knew him commented, Chris was a devoted father and husband. He was my best friend. His world revolved around his family first and of course, his music, second," Vicky added. "The outpouring of love and support from his fans, friends and family means so much more to us than anyone can know. Thank you for that, and for understanding how difficult this is for us."
