[SPOILERS AHEAD] ASTRO's Cha Eun Woo made a guest appearance on the show in order to assist the crime scene crew. Kim Ji Hoon played the role of the victim's husband, Cha Eun Woo as the victim's lover, and A Pink's Eunji, as Cha Eun Woo's wife. Yang Se Hyung was an individual living in the wild and Jang Jin was the camp site's caretaker.
Jang Jin carefully inspected the victim's side, which had been likely punctured after experiencing a devastating fall from a rocky cliff. The others also set out to search the area for any clues as Eunji happened to find a bloody skewer laying around.
The members found an earring belonging to the victim, as well as a photo inside Cha Eun Woo's tent beside fishing gear. The crew also found a package containing mysterious white substance and a syringe inside Yang Se Hyung's bag, which he stated was for his allergic reaction.
Cha Eun Woo was suspicious of the victim's husband Kim Ji Hoon, pointing out that he received much stress from his housewife and often drank a lot despite his flourishing school days.
Later, Detective Park Ji Yoon discovered a letter stating that Eunji and Cha Eun Woo's supposed daughter Cha Geum Jjok was murdered. Upon further investigation, the members found the victim's cell phone as they checked the call logs, heightening the suspense even more.
In the end, Cha Eun Woo was pointed as the culprit with the most votes, causing him to go behind bars. Are you enjoying this season of 'Crime Scene'?
