Case

Situation

On the Kometo Bridge, Tokujiro Nagai told Tsutomu Oshiro that he had something to discuss with him, after making him drunk by giving him a Scotch. While Oshiro's back was temporarily turned, Nagai hurled a flashing boomerang and then quickly drew Oshiro's attention to it. When Oshiro looked after the mysterious glowing object flying by, Nagai grabbed his legs and tipped him over the bridge railing to his death in the dried-out riverbed.

Murder
	Location: Kometo Bridge Victim: Tsutomu Oshiro Age: 30 years old Cause of death: Blunt force trauma after falling Culprit: Tokujiro Nagai

On a sunny afternoon, the Detective Boys were remarking about the "UFO incident" that happened rather recently around the area. Mitsuhiko said that there have been three sightings since the month started. And allegedly, it was something glowing gold in the sky, with some witnesses of aliens on the riverbed. Later, they noticed a shop situated nearby named "Nagai's Toys", and the curtains of it seemed to be opened. However, as Genta tried to open it, the door was locked.

Everyone here knows this store. Ayumi said that the store was run by a nice old couple. Genta added that the toys they sell are too old and never the ones he wants. The majority decided to leave. At this time, Genta's strawberry-flavored ice cream imperceptibly stained Conan's clothes. Their every move was monitored specifically by the debt collector, Tsutomu, who was behind the window of the store. He was negotiating with the store owner, Tokujiro, concerning the money that Tokujiro had borrowed from him. Tsutomu discovered that the kid with glasses kept staring at a toy engine that was deposited on top of the shelf. As he was touching the toy engine, it fell from the shelf to the ground. And apparently, the little mechanical pieces of the toy were scattering all around the floor. And Tokujiro got quite angry with him because he claimed that his wife treasured this engine.

Tsutomu's aggressiveness made Tokujiro give him a bottle of scotch, and Tsutomu drank it straight away. After that, Tokujiro led him to the Kometo Bridge, and the scenario described before happened.

Meanwhile, the Detective Boys were still searching for the curious UFO under the bridge. Conan found a "flashing boomerang" on the ground, and when he pressed it, the light started glowing gold. And not far away from it, the corpse of Tsutomu was lying under the bridge.

Megure declared that it was an accident, but Conan rebutted his perspective. Since he discovered a coupon for half off at a restaurant called "Shinobiya Ramen" that was put inside his wallet. Conan deduced that he must be desperate to eat ramen that day, and it seemed fairly out of left field that he took a complete different route from the ramen restaurant. Hence, most of the clues did not look plausible. In addition, Conan identified something black on top of the victim's hand. What could it be?

In "Nagai's Toys", Tokujiro was fixing the toy engine that Tsutomu broke. He heard some noise outside, and as he opened the door, Conan asked if he could stay in his store for some time because their parents had not yet arrived home. At the same time, Tokujiro found out that the boy in front of him seemed to be the kid who came to the toy store ten years ago.

Resolution

Conan walked into the store, started reasoning, and deduced that the shop owner was the culprit. He first determined that his shoulders could not be lifted by looking at the uncleaned dust on top of the cabinet, but the bottom half of the cabinet was cleaned. Therefore, this would not explain how the toy engine ended up being broken since he had some issues with his arms and would definitely not reach the high shelf where the toy engine was deposited. Even though he claimed that no one had visited him the entire day, Conan found some show polish near the entrance; this is precisely positive proof for the presence of a second person. Lastly, the victim had a strawberry-flavored ice cream smell, which can only be explained if he was in the store today, as Conan touched the door of the store with Genta's ice cream during the afternoon. Moreover, the "flashing boomerang" toy is quite rare nowadays. Thus, Conan speculated that he ought to be the person who got hold of these toys easily, as well as the numerous UFO incidents that were also caused by his experimenting with the toy. Finally, the decisive proof was that one of the components of the toy engine that the shop owner was fixing was missing and got into the victim's shoe.

Tokujiro Nagai murdered Oshiro in order to avenge the death of his wife. Mrs. Nagai was hospitalized due to a serious sickness, but Tokujiro's earnings were too modest to afford her treatments, so he was forced to borrow money from Kuromaru Finance. Oshiro, whenever he came by to check on the investment, callously bullied Nagai, which the old man endured for his wife's sake. But then Oshiro decided to demand repayment from Mrs. Nagai, heedless of her condition. When she heard that her husband had plunged himself into debt, Mrs. Nagai suffered a breakdown which contributed to her death soon afterwards.

Young Shinichi reasoning the culprit who broke the toy engine ten years ago.

Upon that revelation, Nagai remembers Conan, or rather Shinichi, from an incident ten years ago, when one of a group of children visiting his toy shop had dropped a toy engine to the floor, breaking it. Shinichi found out which child had done it, but Nagai kindly refused to run after the offender for this accident, because he believe the child would come back by himself, which he did.

The startlement from this realization convinces Nagai to turn himself over to the police, and Megure orders Sato to conduct a thorough investigation of Kuromaru's dubious business practices. When Megure asks Nagai why he has decided to surrender himself, Nagai replies that a "mysterious boy who has remained unchanged for ten years" has influenced him into doing so, believing him to be a sort of messenger from his late wife to remind him that he had once had faith in the boy who broke a toy to take responsibility and therefore he should take responsibility himself.
