[Spoiler] "Missing 9" Did Choi Tae-joon murder Ryu Won?

The case of the deserted island is becoming more and more mysterious.

On the latest episode of the MBC drama "Missing 9", the first death of Yoon So-hee (Ryu Won) was predicted as homicide while Ra Bong-hee (Baek Jin-hee) became a suspect.

Ra Bong-hee thought of the fall of death but she told Investigator Oh (Min Sung-wook) that she didn't remember. At the same time, Yoon Tae-yeong (Yang Dong-geun) heard that his sister's body had been found and headed to China. The airport security told him Yoon So-hee might've been murdered. She'd not died in a plane accident but someone may have killed her.

More people were appearing on the island of distress where Seo Joon-oh (Jung Kyung-ho) and Ra Bong-hee were. Lee Yol (Chanyeol) and Ha Ji-ah (Lee Sun-bin) and Yoon So-hee were on the camp. However, Yoon So-hee treated Seo Joon-oh coldly. It looked like she was thinking of how much she hated him rather than hopeful that he lived. She acted as if Seo Joon-oh was involved with Sin Jae-hyeon's (Yeon Je-wook) death.

Yoon So-hee tried to kill herself. She jumped into the sea and everyone else saved her. Yoon So-hee then said, "Everyone is going to die anyway".

Ha Ji-ah who jumped into the water to save Yoon So-hee, was hurt. She scraped her leg on the corals. The problem was that it wouldn't stop bleeding. Everyone started looking for something that would help her and ran into other survivors; Jeong Gi-joon (Oh Jung-se), Choi Tae-ho (Choi Tae-joon), Hwang Jae-gook (Kim Sang-ho) and Tae Ho-hyang (Tae Hang-ho).

At the end of the episode, Yoon So-hee saw Choi Tae-ho kill someone. She shook with fear as she met eyes with him. Did he kill Ryu Won?
