Chapter 14 — The Mysterious Shooting Message Case

The Junior Detective Boys watch as a sniper shoots a balloon by the river. Later Conan sees the sniper held at gunpoint by two other men. When the Junior Detective League gets there, the gunmen have left; however, Conan finds the numbers 3540405162 on a calculator the sniper left behind. They call the police and find out the sniper, Yamabe Koichi, and his wife, Eri, were recently reported missing. The message is broken when Conan turns the calculator upside down to discover the actual code. The code reveals that Koichi is going to shoot someone on the Shoho train on the 29th at 1:00pm. Conan and the police manage to track the sniper down and rescue him and his wife. The men holding Koichi hostage were part of the Tiger Dragons gang and wanted to assassinate the prosecutor for arresting their leader. (Source: Wikipedia)
