Suicide disguised as homicide ice cube➕knife

23-24, Serial Murder on Luxury Passenger Ship

The master was stabbed to death by a knife, the doors and windows were locked, and there was blood on the door frame, indicating that the door was open when he was killed, and there was no murder weapon in the room, indicating that it was not suicide, and the door was closed by the deceased himself.

49-50, Diplomat Murder

The victim had red spots on the neck, and there were poisonous needles nearby, strangulation and poisoning could cause death by suffocation. The keys were in the second pocket of the victim's pants.

Heiji's wrong reasoning: The fishing line is used as a key delivery track, and the key is fixed with transparent glue inside. After locking the door outside, the key is sent back through the door seam. But because the victim is sitting, the key cannot be returned to the second pocket.

The secret room was an illusion, and the murderer used a needle to pierce it when he entered with the others. When entering the room, the symphony was to cover up the victim's scream, and a stack of books was placed to cover the victim's painful expression.

Question: At the time of death, will there still be screams after being stabbed by the poison needle after the sleeping pill is in a coma?

【Physical Secret Room】

53 ~ 54, fog tengu

The temple, the room next to the waterfall. The high windows of the room and the platform railings outside the room are used as inclined bases to be covered with wooden boards to guide the river flow into the room. The murderer sat on the raft with the body covered with oil cloth and floated to the top of the room as the water filled the room, hung the body on the ceiling beam, and then let the water out. How to release water: Crawling from the skylight, after digging a hole in the wall from the outside, the water in the room will automatically rush down the balcony together with the wall fragments due to pressure.

Because there was no trace of the murderer dragging the body to the ceiling at the scene, it is believed that the victim committed suicide by climbing a rope to the top beam and wrapping his neck around his neck.

The student invited Lan Conan to go to the collection room to pick up the movie and watch the collection together. When leaving, the student asked Lan to make sure the window was locked. At 8:55, the three returned to the living room, and the students pushed their carts to the study to deliver wine and movies. After the students return to the living room after delivering their things, they check again whether the windows are closed and then return to the living room at 9:15. Everyone played cards, and the lady went back to her room to rest. At 12 o'clock, everyone rushed to the door of the teacher's study, who didn't answer the students' calls, and went around to the floor-to-ceiling windows outside after hearing the sound of the projector running but unable to open the door.

The floor-to-ceiling windows were open, and there were many messy footprints on the snow in front of the windows. The projector in the study focused on the teacher who was nailed to the cross. The scene was set up as the last scene of the bloody wedding that the teacher watched.

The study door and other windows were locked from the inside, and the door seam was sealed with rubber. And the other side of the window is the cliff and the sea, the only entrance and exit is the floor-to-ceiling window that everyone enters.

According to the degree of corpse corpse, the death was more than 1 hour, so the murder time was from 9:00 to 11:00. There were wounds on the back of the head, which were wounded first, and then nailed to the cross with wooden pegs inserted into the chest. The student confirmed that the dowel was the one in the collection room, and the crime was delayed until after the student took the film.

But there are no footprints on the corridor roof.

There is a ladder print on the roof of the storage room. The lock of the storage room window was stuck with a twig. The study was locked with a projector roll film, and the murderer entered and exited through the main entrance of the study, disguised as a secret room entering and exiting through the window.

151-152, the secret room on the eve of marriage

Heiji and Ye came to Tokyo for a wedding, where Xiaolan and Ye You friendship began. In the evening, when Maori and his party were about to leave, they heard the sound of the window glass breaking in the room on the second floor. They rushed to the corresponding room and found that the housekeeper Shigematsu had died in the room inside the ensuite room. The outside room and the inside room were locked, and the keys were in On the victim, no one or object went out after the window of the outside room shattered. Both windows of the interior room are locked. He was killed by being stabbed in the chest with a sharp knife. Suicide is excluded, as the knife should fall next to the corpse. And if he was killed by suicide and ran to the outside room with his last breath, smashed the window glass and threw the knife, there should be blood on the window. And the traces at the scene are more like being dragged by the murderer. Based on this, it can be inferred that there are two possibilities for the window glass to break: 1. The murderer and the victim had a dispute; 2. The murderer saw someone outside the window deliberately smashed it to attract people. Either way, the murderer was still on the scene when it shattered, and then disappeared from the room with the murder weapon in a short period of time. 5 suspicious points: 1. The murderer had already set up the room as a secret room, so why did he take the knife away from the scene; 2. Why did the murderer drag the corpse to the inner room; 3. Why only the room where the corpse was located had the lights turned on; 4. The most suspicious The cat that ran out from behind the corpse; 5. The relationship between Ying Ting's actions and Xiao Feng.
