Ep. 108: Conan deduces Walter murdered Celia Kohler and locates her body beneath a flower.

Matthew reveals he buried stolen jewels in Walter's yard, prompting police excavation. Conan suspects Walter of murdering Celia Kohler based on his expression. The Junior Detective League interviews Sean Moss, who initially misidentifies digging sounds from Walter's property as coming from a neighboring construction site. Conan gathers everyone at Walter's house to present his theory, identifying the victim's remains under a flower that grew from a gift Celia received on the day she disappeared. Walter confesses that Celia's death was accidental; he pulled his hand away, causing her to fall to her death after he learned of a financial error she made. Her body is recovered, and Matthew, having received probation for robbery, returns home to bury Celia properly.
