What's the Story?

While walking down a deserted road after completing a job, Conan, Ran, and Kogoro hear the sound of an alarm whistle and a scream. The sound leads them to security guard Nezu Goro, who has been stabbed in the stomach with a knife. Nezu points towards the main avenue and says the words "white clothes" before he dies. Furthermore, at the top of the stairs Nezu is thought to have fallen down is the crying and screaming Yuki Keiko and the body of her husband Yuki Hideto, the IT company president. Conan heads towards the main avenue in pursuit of the culprit where he encounters a young man dressed in black.
