Ep. 59: The First Errand Murder Case involves a kidnapping and a collapsing building mystery.

59

Conan and the Junior Detective League monitor the Toddler Shopping Day, where Christopher encounters strange events. Conan realizes the child witnessed a murder, but the boy continues shopping unaware of the danger. The culprit kidnaps Hiroshi, drugs him, and places him with a corpse in a building scheduled for demolition. After locking Conan and the gang inside, the killer escapes as the structure begins to collapse. Conan locates a water pipe leading outside and safely guides everyone out to confront the murderer. The killer admits to murdering a loan shark who demanded excessive payments despite the debt being paid. The boy wakes up and asks the former shopkeeper for items on his list, moving the killer to tears that his store was remembered. The situation is darkly humorous because Hiroshi never actually saw the body.
