In 2010, Gray was planning to tour with the supergroup, Hail!, but on May 24, 2010, he was found dead in an Urbandale, Iowa hotel room. Circumstances surrounding his death at the time were not immediately known; an autopsy suspected his death was not intentional but did not reveal the cause. The day after his death, the remaining eight members of the band held a live, unmasked, press conference alongside Gray's widow and brother. On June 21, the cause of death was confirmed as an accidental overdose of morphine and synthetic morphine substitute fentanyl.
