Chris Cornell's widow says his battle with addiction led to his suicide: 'He loved his life'

"He wanted to be there for his family," Vicky Cornell said.

"He loved his life," Vicky Cornell told ABC News' Robin Roberts in her first television interview since the family tragedy. "He would never have ever left this world."

While most remember the former Soundgarden and Audioslave frontman by his influential legacy in the music world, Vicky Cornell recalls him as a loving husband and father to their two children: Toni, 13, and Christopher, 12.

“Our family was his everything,” she said. “As soon as he got off stage, he was a dad, he was a regular dad.”

Chris Cornell, 52, was found dead in a Detroit hotel room on May 18. His death was ruled an apparent suicide, according to the Wayne County Medical Examiner's Office.

Medical reports note that though seven different drugs were found in his system, these were not a contributing factor to his death.

Vicky Cornell, and others in the medical community, however, argue that there is more to the story.

"He wanted to be there for his family, for his children. He loved his life," Vicky Cornell said. “I don't think that he could make any decisions because of the level of impairment.”

Dr. Richard Cote, the chair of the department of pathology at the University of Miami Miller School of Medicine, who conducted an independent analysis of Chris Cornell's autopsy, told ABC News that two drugs found in his system at the time of his death may have resulted in impaired judgment and motor functions.

"They were not at levels that would’ve caused his death; in other words, it wasn’t an overdose," Cote said. "But what the two drugs did individually and in combination was to really impair his judgment and make him psychically unable to be responsive in ways that he normally would be responsive."

'There were signs’

Vicky Cornell recalled the year before her husband’s death, when she said he fell back into addiction after being sober since 2003.

The new drugs changed her husband, she said.

“The brain of someone who has a substance use disorder is different from that of … someone who doesn't,” Vicky Cornell said. “He relapsed.”

During one weeklong period, “he took 20-something pills,” she said. “And in a nine-day period, 33.”

"He had really delayed speech," she recalled of the dark time when her husband's addiction took over. "He was forgetful.”

Last March, Chris Cornell reached out to a colleague for help, writing in an email, “Would love to talk, had relapse.”

Just two months later, he uncharacteristically walked off stage in the middle of what would turn out to be his final performance and died hours later in his hotel room.

Vicky Cornell said explaining what happened to her children the following day was “the most tragic thing you can ever go through.”

“They’re, you know, crying, ‘Is Daddy OK?’” she recalled. “And I said to my babies, "Yeah … the ambulance is there and they're taking Daddy to the hospital, and I'm just going to go to the hospital.”

Vicky Cornell said her memories of the night her husband died still weigh heavily on her.

“I know that people say ... you can't blame yourself,” she said. “I'm trying not to, but there were signs.”

'You think addiction is a choice, and it's not'

She said she is now making it her mission to raise awareness and destigmatize addiction, and encourage others to speak openly about the topic.

“People think that addiction is like, ‘Oh, you were an addict,’” she said. “People don’t recognize it as a disease.”

“You think addiction is a choice, and it's not,” she added. "I think that if there was less stigma around it, more people would speak up."

She added that addiction has now "crossed over all sorts of socioeconomic boundaries ... it's everywhere."
