Delaney’s family said Sunday they have received a copy of the medical examiner’s report on his death. It states he died of natural causes. His family says he passed in his sleep due to cardiac dysrhythmia, a consequence of myocarditis, which is an inflammation of the heart. It’s most commonly the result of a viral infection.
