The former K-pop band member Goo Hara was found dead on Sunday in her home in Seoul, South Korea, in what the police were calling a suicide. She was 28.

The singer, who was known as Hara to her fans, was a member of the wildly popular K-pop girl group Kara. The South Korean group, which released its first album, “The First Blooming,” in 2007, was part of the early groups that helped usher in the K-pop global phenomenon.

After the group disbanded, Hara embarked on a solo career in 2015, with the debut of the EP “Alohara” (Can You Feel It?). She also had some television and film roles.
