Case File: Missing Officer Deok
About
(Please note that this is a work of fiction based on my theories after watching the Mystery Investigation Unit Season 2 music video.) It has been two days since the Mystery Investigation Unit began investigating a mysterious murder in a tunnel. Officer Deok felt something through his Sixth Sense at the scene, and while returning there alone after work, he went missing. Coincidentally, as soon as Deok disappeared, a fire broke out in a building just past the tunnel. While investigating these three incidents (the tunnel murder, Officer Deok's disappearance, and the building fire) together, you discover a common link: a specific, unique emblem left behind at each site. It is the mark of a certain organization. Having discovered this, you are now on your way to inform the team. Will you be able to rescue Officer Deok and solve these cases? (Rank Hierarchy: Superintendent Inspector Assistant Inspector Sergeant Officer)
