News leaked by an employee in the emergency response center revealed that on October 14, 2019, at approximately 3:20 p.m. KST, Sulli was found dead by her manager after hanging herself in the second floor in her house in Seongnam, south of Seoul. The manager reportedly visited the house when he was not able to reach her, after speaking with Sulli via phone the previous day at 6:30 p.m. KST. Police stated that they were investigating it as a possible suicide as there were no signs of foul play or a break-in. They found a handwritten note in her diary in which she described her feelings, but concluded that it was not a suicide note. On October 15, police filed for an autopsy to confirm the cause of death and performed it the following morning, concluding that her body did not show any signs of death due to external force, and it is likely a suicide that occurred on the night of October 13 or the morning of October 14.
The funeral was initially closed to the media as well as fans and was privately held by family members and friends. However, SM Entertainment opened a separate venue in Severance Hospital's funeral hall in Sinchon-dong, Seoul on October 15 and 16 for fans wishing to pay tribute. Various celebrities and companies, such as previous bandmates Krystal, Victoria Song, Amber Liu and Luna, fellow singer and friend IU, Dynamic Duo, and the premiere of the film Gift, canceled their activities to mourn Sulli. On October 17, following a four-day private funeral and mourning ceremony at a Seoul hospital, Sulli was buried at an undisclosed location.
Sulli's death was linked by various media outlets to depression caused by cyberbullying. Following her death, it was revealed that Sulli had repeatedly asked her agency, SM Entertainment, to take strong measures against the malicious comments and cyberbullying. A total of seven petitions were posted at the South Korean presidential office website demanding tougher punishment for cyberbullying and strengthening use of the real-name system when posting comments and creating accounts. Moreover, the political circle discussed various ways to prevent such a tragedy from happening again. An act under the proposed title "Sulli Act" was mentioned at a general audit of the Korea Communications Commission on October 21, where Rep. Park Dae-chool of the Liberty Korea Party said he is writing a legislative proposal to enact a new law to increase the responsibility of comments by introducing an Internet real-name system. Moreover, on October 25, Rep. Park Seon-sook proposed a partial amendment to the Act on Promotion of Information and Communications Network Utilization and Information Protection, which imposes an obligation for information and communication service providers to delete hate comments. In addition, the amendment included marking malicious comments as illegal information, and provide anyone who saw malicious comments, not just the one being attacked, the ability to request its deletion. On the same day, Rep. Park Dae-chool also proposed an amendment to the Act on Promotion of Information and Communications Network Utilization and Information Protection which would allow the disclosure of full names of people posting comments under usernames and strengthen accountability of online comments by disclosing IPs. On October 25, 2019, Kakao announced that they are temporarily disabling comments on entertainment news to prevent hate comments and removing related search terms when searching people's names for a year.
