Case Closed (1996)

Season 4

Episode 1: The Set Up

Richard Moore is in the hospital after injuring his ankle. While there, he witnesses a shadow of a murder. After causing an uproar three times and finding the place where the murder took place was an empty room, the murder occurs on the fourth time. Conan figures out that light is being reflected to that room and that the first three times were in a different room while the fourth one occurred in the room Moore presumed. The culprit has an alibi of talking to the nurse in another room at the time of the murder. Moore is desperate to go into the Sleeping Richard phase to prove his innocence and happily exclaims it's coming when Conan secretly shoots a tranquilizer dart. Conan disproves the culprit's alibi and proves Moore to be innocent.
