On July 9, 2020, Park's daughter reported him as missing after reportedly taking sick leave, alerting the National Police Agency at 5:17 pm KST. His cell phone was reported as turned off in the Seongbuk District of Seoul, with his daughter finding a will-like note. Authorities began using search dogs and drones in Seongbuk District. Around midnight, his body was found near Sukjeongmun on Bugak Mountain in northern Seoul. With no foul play found at the scene, it has been broadly reported that the death is considered a suicide.
Park's family accepted a state funeral, held at Seoul City Hall and streamed online on July 13, 2020. About 992,000 people have paid tribute to Park on an online city-run mourning site.
