Kim Jong-hyun, a key member of one of South Korea's biggest boy bands, SHINee, has died. He was 27.
The singer, who performed under the name Jonghyun, was found unconscious in a rented Seoul apartment on Monday evening. He received emergency CPR treatment upon his arrival at a hospital but was later pronounced dead.
Investigators believe he died from inhaling toxic fumes, after discovering coal briquettes burned in a frying pan in his apartment.
Kim's band, SHINee, one of South Korea's most popular boy bands, signed with the country's biggest music label, SM Entertainment, in 2008. Kim also had a successful solo career as a singer-songwriter. His debut solo album in 2015 topped the US Billboard World Albums chart.
South Korean news agency Yonhap reports that Kim's sister made an initial report to police after receiving a text message from the singer saying "Please let me go. Tell me I did well", and "final farewell".
SM Entertainment has issued a statement confirming Kim's death. The statement reads:
