SEOUL, South Korea (AP) — South Korean actor Kim Sae-ron’s death this week has triggered an outpouring of grief and calls for changes to the way the country’s celebrities are treated in the public arena and on social media, which critics say can foster a culture of harassment. The 24-year-old, who began her career as a child actor and earned acclaim for her roles in several domestic films, including the 2010 crime noir “The Man from Nowhere,” was found dead by a friend at her home in the country’s capital, Seoul, on Sunday. The National Police Agency has said that officers are not suspecting foul play and that Kim left no note.
