Dengue fever
The Tarrant County Medical Examiner's Office concludes that Irons died from a cardiac arrest due to a severe blockage of a main artery of the heart. The official autopsy report lists also a second cause of death as "acute mixed drug ingestion", listing alprazolam, methadone, benzoylecgonine (a metabolite of cocaine), and traces of methamphetamine as the drugs found in Andy's body at the time of his death. Initial press releases cited Dengue fever as the cause of Irons' death; however, the autopsy report conducted by the Tarrant County Medical Examiner's office were negative for Dengue and other flavivirus. It is unclear why rumors that Dengue fever contributed to Irons' death proliferated.
