Jonghyun’s sister just confirmed that he died by suicide. The exact cause of his death is carbon monoxide poisoning.

“On December 18, 2017 at 4:42PM Jonghyun’s older sister reported to Police that her brother was about to commit suicide. We went to his residence in Chungdam and discovered that he had attempted to commit suicide with brown coal briquettes lit inside a frying pan. Emergency responders were with us at the time so we rushed him to the Konkuk University Hospital in a state of cardiac arrest.” — Gangnam Police

News reports are stating that Jonghyun sent his sister a suicide note, which is when she called the police to help him. Jonghyun texted the suicide note to her.

“It’s been really hard for me until now. Please let me go, and tell me I’ve worked hard, last good bye.”

Burning coal briquette is a type of carbon monoxide-induced suicide that has become increasingly popular in East Asian countries.
