Conan was returning the Prof’s phone to Haibara-san when the Detective Boys noticed that Takago-keiji went inside a jewelry store. They followed him and the policeman was surprosed to see them there. They were looking at this brooch that Takagi-keiji wanted to buy when a burglary happened. They chased the thief until he jumped from a high building and fell down on a truck. When they looked down, they saw the thief dead.

What I always like about this police stories is when everytime Shiratori-keiji bullies Takagi-keiji. Like in this episode where he tried to make Takagi-keiji frustrated by saying that no one would like to receive a brooch that was tainted with blood. It was really funny.
