With tonight’s tribute concert for music legend Chris Cornell about to take place, fans of the late Soundgarden and Audioslave singer may be interested to note that late last year his wife sued her late husband’s doctor for malpractice.

Cornell’s widow Vicky Cornell sued her late husband’s doctor for medical malpractice, claiming he was “negligently and repeatedly” prescribing medication that ultimately led to the singer’s death on May 18, 2017.
