Kim said that there were no signs of foul play and that police did not find a suicide note. "The investigation is ongoing and we won't make presumptions about the cause of death," said Kim, adding that security camera footage at Sulli's home showed no signs of an intrusion.
In a statement sent to reporters, SM Entertainment, Sulli's agency, said her death was "very hard to believe and sorrowful." Sulli's legal name is Choi Jin-ri. She began her singing career in 2009 as a member of the girl band "f(x)" and also acted in numerous television dramas and movies.
She was known for her feminist voice and outspokenness that was rare among female entertainers in deeply conservative South Korea. She recently appeared in a TV show and spoke out against online backlash she received over her lifestyle.
