Crime scene: 162 mystery solving puzzles to find out who the murderer is

Chapter 102

The famous writer Kiyoharu Matsuki died in the study of a villa in the deep mountains.The cause of death was drinking wine mixed with poison.The presumed time of death was two days ago.

There is a commonly used word processor on his desk, and the text left on the screen is a "suicide note".No other person's fingerprints were detected from the keyboard.

The following is a conversation between the two criminal police officers investigating the scene.

Detective A: "Well... the suicide note left on the word processor by the troubled Pine, can it be said that he committed suicide by taking poison consciously?"

Detective B: "Strange, isn't the death two days ago? If so, at least Song Mu didn't type this suicide note."

Sure enough, a suspect was found by starting with the poison, and this person was a competitor of Pinewood.Although the search has made progress, the police have not been able to solve the mystery of the "word processor suicide note".

Then, why did detective B be sure that the suicide note on the word processing screen was not typed by Matsuki himself?
[Answer] The power plug of the word processor on site is not plugged in.This means that the memory battery is used, but with current technology, it is impossible for the machine to work continuously for two days without an external power supply.The longest at best l0 hours.Probably the criminal gave Pine the wine mixed with poison in advance. It is estimated that Pine sneaked into the villa after drinking the wine and died of poisoning, and used the floppy disk that came with him to call out the suicide note and left it on the screen. The time may be several hours before the body was found .

The reason why no fingerprints of anyone other than the deceased were left on the keyboard was because the floppy disk was brought by the criminal himself, and the file could only be recalled with the recall function.If this is the case, you can only press a few keys with gloves on, and your fingerprints will not stay on them, and the fingerprints on other keys are all left by the pine wood itself.
