Chris Cornell’s wife, Vicky Cornell, is still searching for answers four months after her husband passed away.

According to People, Vicky recently flew to Detroit and met up with the medical examiner who declared Cornell’s cause of death as suicide by hanging. Photos of Vicky arriving at the airport were first uploaded by The Blast on their website.

The Soundgarden member was found dead in his Detroit hotel room in May, just hours after he and his band members performed at the Fox Theater. Prior to his death, Cornell called his wife. Vicky later on revealed that her husband just kept saying “I’m tried” throughout their phone call. He also sounded groggy.

In his toxicology report, it was discovered that Cornell had various types of drugs in his system. Cornell battled addiction throughout his life. A month after his death, Vicky spoke with People to say that Cornell wasn’t depressed. Rather, his death was an effect of his addiction.

“My Chris was happy, loving, caring and warm. This was not a depressed man – it wasn’t like I missed that. What I missed were the signs of addiction,” she said. The mom of three also said that she’s certain her husband would still be alive if he did not relapse on drugs that night.

“He didn’t want to die. If he was of sound mind, I know he wouldn’t have done this… Addiction is a disease. That disease can take over you and has full power,” she said. Cornell was previously prescribed Ativan to help improve his sleep patterns. But on the night of his death, he decided to double his dose.

In August, the couple’s eldest daughter, Toni, 13, paid tribute to her dad by singing “Hallelujah” with One Republic in “Good Morning America.” The touching tribute left the live audiences in tears. While speaking with Rolling Stone, Toni said, “It’s an honor to perform this for my dad and Chester and to sing for them.”

Cornell is survived by his wife and two children, as well as her 17-year-old daughter, Lily, from a previous marriage.
