Fans mourn at Asan Medical Center funeral hall, December 20, 2017 In December 2017, Jonghyun rented an apartment in Cheongdam-dong, Gangnam District in southeastern Seoul for two days.[80] He checked in at 12:00 PM KST on December 18, 2017. Later that day, at 4:42 PM, Jonghyun's older sister, Kim So-dam, made an initial call to emergency responders, reporting that she believed he intended to commit suicide, because he had sent her a number of messages on KakaoTalk with words such as "last goodbye" and "say I did well". He was last seen at a convenience store next to his apartment. Jonghyun was found unconscious in his apartment by the police and rescue workers at around 6:10 PM. He was immediately brought to Konkuk University Hospital in a state of cardiac arrest. He received emergency CPR treatment. However, he failed to regain consciousness and was pronounced dead at the hospital at around 6:32 PM, aged 27. Investigators believe he died from inhaling either toxic fumes or smoke, as they discovered coal briquettes burnt on a frying pan upon arriving at the apartment. The police stated that, at the request of Jonghyun's family, a post-mortem would not be carried out, and they declared his death a possible suicide
