The culprit is Tontetsu, who was craving fake copies of the Buddha statue at the temple and sold them online. Jun Murata, the expert, discovered that the statue was fake, thus motivating Tontetsu to kill him to cover the smuggling. Kantetsu also discovered the truth, and was killed too. Tontetsu then tries to escape, but Kogoro, who was freed from the secret room thanks to Heiji and Conan, apprehends him.
