DMX passed away on April 9 at age 50.
He'd been hospitalized for a week before he did and there has been misinformation and speculation about what killed him, including a report that he had COVID.
New York magazine has obtained X's official cause of death from the Westchester County medical examiner's office:
"DMX officially died from a cocaine-induced heart attack that caused a lack of blood circulation to his brain, a source from the Westchester County medical examiner’s office told Vulture. “It was cardiac arrest for a period of time, so there was no circulation to the brain,” the source said, later explaining that acute cocaine intoxication had “caused this chain of events.”
