Meitantei Conan › Season 1

Chapter 8 — Art Gallery Owner Murder Case

Ran forces Conan and Kogoro to visit an art museum where a medieval suit of armor is rumored to have moved on its own. They meet Ochiai the Beika Art Museum curator, Iijima, Kubota, and Manaka the owner who plans to convert the museum into a casino despite high profits. The trio finds an unguarded restricted area at the museum, where they find Manaka's corpse pinned to the wall with a sword. Manaka's brutal murder is examined on a security camera where the investigation team witnesses him being killed by a suit of armor; his death mimics Divine Punishment, a portrait depicting a knight slaying a demon. Also in the video, it appears that a sheet of paper, allegedly written by Manaka, points to Kubota being the murderer. Conan realizes that Manaka's pen was retracted during his murder. The bloody armor is found in Kubota's locker but Conan is convinced that he is being framed. He drops hints allowing Kogoro to determine that Ochiai, the museum's curator, is the killer; Ochiai is revealed to have written Kubota's name on the paper in advance, not Manaka. The pen in Ochiai's possession has no ink. Ochiai confesses to the murder as it was his attempt to protect the museum from becoming a casino, then tried to frame Kubota since he was secretly selling museum art pieces. The museum remains open as the public protested against its destruction. (Source: Wikipedia)
