The police presume that a boulder rolled off the hill and killed Umezu. However, Conan reveals that there are scratch marks around the spot where the bolder laid revealing that someone wedged the boulder out of its placement and that it was a premeditated murder.

After further investigation, Conan tranquilizes Kogoro and reveals the murderer to be onsen manager, Koichi Maekawa. Conan reveals that Umezu was actually drowned and was dead before the boulder rolled down the hill, evidenced by the dirt under Umezu's fingernails, a sign that he was struggling. Conan then explains the boulder was used to create an alibi for Maekawa. Conan points out that the boulder was held in place by a wooden block which was connected to a line with a buoy at the end. When the tide lowered, the buoy pulled the wooden block and caused the boulder to roll off. Maekawa confesses and reveals that the president was pressuring him to sell the land to the onsen and that Umezu also pressured Maekawa's father which indirectly resulted in his death.
