Chapter 96

Outside the villa gate, Baiyan Zhenyu and Conan are investigating the scene and whispering their guesses.

Conan observed the doorbell and said, "when the doorbell rang, everyone else did stay in the living room except Xiaolan and Yuanzi, so there were only two possibilities, either there were other accomplices, or it was done through some special props and techniques."

"The first situation can't happen, because I observed the snow outside the door and there were no other people's footprints."

Bai yanzhenyu agreed with Conan's reasoning and told Conan what he had observed before.

After they checked outside for a while, they found some doubts. For example, there was a place on the staircase that was not covered by falling snow, there were strange grooves on both sides of the escalator column, and a kite line with a cut rubber band stuck at the end of the line.

"As expected, the murderer was indeed someone in the villa. The groove above the column should be left by the kite line."

Bai yanzhenyu's eyes narrowed slightly, carefully observed the position of the groove, column, handrail and doorbell, and suddenly realized: "I understand the murderer's modus operandi."

"First, tie the kite string with rubber band around the posts at both ends in front of the door, then make a small circle at the other end of the kite string, and then tie the rubber band."

"After that, tie the rubber band around the neck of the stiff Sugiyama teacher after his death, and make use of the elasticity of the rubber band to make him hang in an inclined position in front of the gate."

"Finally, when the rubber band loses its elasticity and breaks in the cold, as long as the position is found in advance, the inclined Sugiyama teacher will fall down and knock the doorbell."

After hearing Bai yanzhenyu's reasoning, Conan agreed excitedly: "yes, in this way, we can create the illusion that the murderer has another person."

After investigating the scene, the two returned to the living room. As soon as they reached the bottom of the stairs leading to the second floor, Dr. Ali called and told them that he did find a copy of relevant case information in Conan's father's study.

Three years ago, a primary school student in class two, grade six, of Beihu primary school, Wangyue meinaizi, hanged herself in the classroom of the ballet club. It is said that her class teacher was greatly criticized because of the pressure of the exam.

"Meinaizi? Isn't that the words left by the killer with lipstick?"

After hearing the name of the deceased, Bai yanzhenyu and Conan were a little surprised, and then confirmed their previous speculation. This time, it was really related to the case three years ago.

Suddenly, Bai yanzhenyu thought of the previous events and reminded him, "Conan, do you remember the words that sendens said?"

"What sentence are you talking about?" Conan blinked blankly. He didn't know what sentence Bai Yan Zhenyu meant.

"That's what he said when he saw the attack on Yuanzi and teacher Miyuan [now, you can't distort the facts and hide them like you did three years ago.]"

Bai Yan Zhenyu thought deeply in his eyes and continued: "it seems that the case three years ago is not as simple as it seems. There must be something hidden in it, and this sendunshi should be the one who knows the inside story."

Just as Bai Yan and Zhenyu were going to ask sendunshi, a scream suddenly came from the room on the second floor.

Baiyan Zhenyu and Conan immediately ran to the second floor and found that the other three teachers were gathered in the corridor. At this time, they were looking at Xiatian gengping's room with a frightened face.

Baiyan Zhenyu had a bad feeling in his heart. He ran to the room and looked around. As a result, he found that Xiatian gengping fell on the bed with his head down, and there were obvious strangulation marks on his neck. It was obvious that he had been killed by the murderer.

Baiyan Zhenyu and Conan came to investigate the scene and found a thick layer of snowflakes on the steps outside the room window, which means that the murderer did not enter and exit from the window, but entered the scene from the door locked by Xiatian gengping and left the scene after killing Xiatian gengping.

Baiyan Zhenyu's eyes swept one by one from mikara's three people, and said in a deep voice, "the body is still hot, which means that Conan and I were downstairs shortly after his death. The murderer can't run down, so the murderer must be one of you."

"Don't... don't be kidding. How can we kill miss Xiatian."

"Yes, we are not the murderers."

"Let me see, you are the most suspect."

Mi Yuan and Huang Zi were shocked. After looking at each other, they flustered and denied Bai Yan Zhenyu's inference.

Baiyan Zhenyu looked around and didn't find props such as ropes. The corners of his mouth rose slightly. He proposed: "there are no props that can be used for crime at the scene, which means that the murder weapon should have been taken away or hidden by the murderer, so I think it's better to search and check his luggage."

Baiyan Zhenyu's proposal was agreed by others, so they went to each room to check their luggage, and then men and women went to different rooms to search each other, so as to prove their innocence.

Before long, the body search ended. The result was beyond Baiyan Zhenyu's expectation and the existence of the murder weapon was not found.

Sakai longyi, who was refuted by Baiyan Zhenyu before, finally found a chance to retaliate. He sneered and said, "hum, we don't have murder weapons. Now you have nothing to say."

Bai yanzhenyu ignored Sakai longyi's ridicule, frowned and thought about the details he might have missed, and then bluntly said to mori: "Mr. mori, two teachers have died now. I hope you can truthfully tell me the secret of the case three years ago."

"I've forgotten that thing forever, but I can give you some simple information."

Sendunshi shook his head slightly. After a moment of meditation, he replied: "Mr. miyara is the head teacher of Wangyue meinaizi, Mr. Sakai is the consultant of the ballet club, and Mr. Nakamura has a very good relationship with Wangyue meinaizi, but they didn't stop Wangyue meinaizi's suicide in time."

After listening to sendunshi's words, mikara Koko three lowered their heads silently. They didn't know whether they were guilty of not saving the students in time or hiding the panic in their hearts.

Although sendenshi didn't give the answer Bai Yan Zhenyu wanted, it indirectly proved that there was an insider in that case. However, if you want to find out the real murderer, you can only continue to look for new clues.

Baiyan Zhenyu returned to Xiatian gengping's room and investigated the scene more carefully. Finally, he found a line like thing at his neck.

"Is this... Hair?"

Baiyan Zhenyu picked up the line and looked at it. He found that it was a hair. His heart suddenly flashed and guessed the real identity of the murderer.
