More details have emerged surrounding 20-year-old South Korean model Daul Kim, who was found dead yesterday. Kim’s boyfriend, who declined to be named in the press, found her hanged in her Paris apartment and alerted police.

Authorities are operating under the hypothesis that she committed
suicide. Kim’s agent tells the AP her mother is arriving in Paris
today. Bloggers in South Korea are speculating she felt the pressures
of the fashion industry.

On October 30, Kim wrote on her blog she was “mad depressed and overworked.” On November 5, she wrote in another entry, “the more i gain the more lonely it is … i know i’m like a ghost i have nothing but myself.” In her last entry, on November 18, she posted a track by Jim Rivers, “I Go Deep,” with the headline “say hi to forever.”
