Following Chris Cornell‘s death in May 2017, which was ruled a suicide by hanging, his family is taking legal action against his doctor, whom they allege harmed Cornell’s mental health.
The singer’s widow, Vicky Cornell, and her two minor children, Christopher, 12, and Toni, 14, filed the documents in L.A. Superior Court on Thursday. (Cornell was also father to 18-year-old Lillian from his previous marriage.)
According to the lawsuit obtained by PEOPLE, Dr. Robert Koblin allegedly “negligently and repeatedly [prescribed] mind-altering and controlled substances” starting in September 2015. The drugs listed in the documents include lorazepam, for anxiety, and oxycodone, for moderate to severe pain.
The documents further allege that Koblin was aware of the Soundgarden frontman’s substance abuse problems and that he wrote the prescriptions without medically examining his patient or checking on how Cornell was responding to the dosage. It also states that the drugs “clouded [Cornell’s] judgment and caused him to engage in dangerous, impulsive behaviors that he was unable to control, which cost him his life.”
