Case Closed: Episode 90 English Dubbed Episode Description: A trip to Hokkaidō to see red-crowned cranes ends tragically when the birds’ caretaker, Shane Mathison, is found dead with an arrow in his chest. Chad, Shane’s son, is the most suspicious when he suddenly left before the crime was discovered, and Lindsey and Tom, Shane’s daughter and brother, are suspects. Conan finds a block of wood in the fireplace, a turtle dove nest on top of the chimney, broken glass in a straight line, and a hurricane window with a scratch on it. The old man's son confesses that he's the murderer, but Conan proves that he's not. Richard is put to sleep and Conan reveals Shane's brother, Tom, to be the killer who set up a spring-loaded crossbow and fired it at the same time as the son.
