Country music singer Luke Bell's cause of death was an accidental fentanyl overdose, according to an autopsy report from Arizona's Pima County Medical Examiner’s Office obtained by NBC News.
The report also determined that Bell suffered from arteriosclerotic cardiovascular disease at the time of his death.
"In consideration of the known circumstances surrounding this death, the available medical history, and the examination of the remains, the cause of death is ascribed to fentanyl intoxication," the report stated. "The manner of death is accident."
The “Where Ya Been?” singer was found dead in Tucson, Arizona, on Aug. 26, nearly a week after he had been reported missing. He was 32.
Bell’s friends and family members remembered the musician's “gentle heart” and “wanderer’s spirit” after his death.
Bell’s family and friends revealed that Bell had struggled with mental illness, and that his struggle became more pronounced after his father died.
“Unfortunately Luke suffered from the disease of mental illness, which progressed after his father’s death in 2015.
Luke was supported through his disease by a community of loving family and friends. Despite this, he was unable to receive the help he needed to ease his pain,” they said in their statement.
