On the June 23 broadcast of JTBC's 'Crime Scene 3', the members went on an investigation inside a spooky mansion for their next case involving the death of mystery writer Jang Se Min.
[SPOILERS AHEAD] During the briefing, Park Ji Yoon, who played the role of Jang Se Min's secretary, suspected he had died from an electrocution. After examining a towel containing salt residue, she claimed that someone had used the combination of salt, water, and his racing toy car to lure him in.
Soon, the members began to point out one another's presumptions. Jang Jin pointed at Yang Se Hyung as the culprit due to his similar lifestyle as the protagonist depicted in the mystery novel. During the inspection, Jang Jin noticed that the toy car had hints of salt on it, causing him to become suspicious even further.
