The Crime-Solving Madman In The City

Ye Yang left Su Huo's office and returned to the classroom. Although the classroom was as lively as usual.

But because Lin Zi is no longer around, Ye Yang always feels that something is missing.

Even when Lin Zi was around in the past, there wasn't much communication between them. But I am really no longer in school, and I miss you a little in my heart.

But the next day, Lin Zi made an overseas phone call to Ye Yang, saying that she had arrived in New York and had contacted the local police station, and she could start working officially tomorrow.

Ye Yang smiled and asked her to take good care of herself abroad, and then both of them fell silent.

Finally, Lin Zi said to hang up, and the phone was hung up.

Luo Xiaoyu on the side knew that the call was from Lin Zi, and after seeing the phone hanging up, he asked: "Do you feel like there is still a lot to talk about?"

Looking at Luo Xiaoyu's slightly cunning eyes, Ye Yang said, "I'm afraid you'll get jealous if I talk too much."

"Tch, I feel like Ming Jing'er in my heart. I know that you and Lin Zi have a good relationship, but it's definitely not to that level, so I have nothing to worry about."

Ye Yang smiled and nodded. It happened that the teacher on the stage who was teaching the criminal investigation course wrote down a difficult question, and then asked him with a smile: "Student Ye Yang, this difficult question was the last question of the Beijing Police Final Mock Examination five years ago. May I ask you How to solve this problem?"

Ye Yang is famous for not listening in class, but he doesn't listen, but he always ranks at the forefront in exams.

Just like the last simulation, it is amazing that Ye Yang can be in school for half a month.

But what about the test scores? Ranked first in the whole year!

If we simply compare scores with the seniors, he is still number one in the school!

At this moment, the teacher asked his opinion by name, and Ye Yang looked at the case written on the blackboard.

"On a cold night, a brutal mutilation case occurred in a dormitory of a school. All four girls in the dormitory died tragically. One of them had her left leg chopped off, and the other had her right leg chopped off. The remaining two had their left and right hands chopped off respectively. After investigation, the criminal investigation team found a sleeping girl in another dormitory.

There was blood on the sole of the girl's shoe, and after DNA identification, it belonged to one of the deceased. Please tell me if this girl is the murderer!"

In this case, there are several tips:

*1: The suspected girl had no conflicts with the four girls in the dead dormitory, and they belonged to different classes and had no contact with each other. "

"2: The school has very intensive surveillance, and the girl has a carefree personality and is a little suspicious. 27

*3: The lifestyle problems of the four girls are serious, and one of them is the daughter of a high-ranking official. "

“4: The dormitory is close to the road, no students from the school have asked for leave, and it is suspected that the girls have a history of sleepwalking.

*5: At that time, the daughter of a senior official did not die immediately, but woke up again after being comatose. The deceased finally wrote the girl’s name in blood! Moreover, the only bathroom in the school at that time had one that was six meters above the ground. There are signs of climbing on the vents, and other places are closed to people. It takes about fifteen minutes to leave through the vent. It took about five minutes for the deceased to wake up from coma. "

This is the title. After reading it, Ye Yang said: "Obviously, the murderer is not that girl."

Monitor Wang Yu immediately said with some disagreement: "If the girl was not the murderer, then why did the murderer write down her name? If she was not the murderer, then there were only five minutes, and the murderer should not have left. She should also be killed and silenced!"

After listening to the words of monitor Wang Yu, other students also nodded.

Ye Yang smiled and said: "There is a very important key factor in the reminder, sleepwalking! If the suspected girl was sleepwalking that night, there were blood stains under her feet. And when someone went to find her, she happened to be there sleep.

"If an ordinary girl from a regular school can still sleep peacefully after killing four classmates in one night, then her personality is definitely not carefree!

"In addition, the only way out is a bathroom vent. And the vent is six meters above the ground with signs of climbing, and it has been ruled out leaving or entering from anywhere. If the girl is the murderer, her soles will be stained The blood stains should remain on the vent. In fact, there is not, and the vent is six meters high. How can a girl crawl back and sleep in the dormitory? If she leaves through the vent and returns to the dormitory, wouldn't it be wrong? Is it unnecessary?"

Wang Yu was speechless immediately, but some students said: "She can use ropes or something like that. The prompt clearly stated that there were traces of her climbing."

"The prompt only said that there were climbing marks, but it didn't say that the climbing marks were hers!" Ye Yang replied with a smile.

Suddenly the teacher on the stage applauded and said with a smile: "Ye Yang's observation skills are indeed very careful, but you still haven't explained anything. Why did the deceased leave the girl's name on the ground?"

"The suspected girl has a history of sleepwalking, so the girl was most likely sleepwalking at that time. She walked to a crime scene, and even though her eyes were open, she did not wake up. She was unaware of everything. She was completely confused. The deceased was severely injured and could not scream loudly. So she mistakenly thought that the girl refused to save her, or she thought that the girl was the murderer, so she wrote down her name so that the investigators could have it. Clues to break the beam."

The teacher's applause rang out again, and he gave a thumbs up and said: "Students, please study hard with Ye Yang. This question is not very difficult. But there is a place that can easily make people confused. That It’s just the climbing marks on the windowsill. Many people will subconsciously think that it is the girl’s footprints, but in fact, the footprints were left by the real murderer!”

The other students all laughed bitterly after hearing this, but Ye Yang suddenly asked: "Is this (Wang's) case a real case?"

"Yes, the person who asked the question is a case that a former teacher in the school personally experienced." The teacher replied.

"Do you have any other tips? This case shouldn't be difficult to solve." Ye Yang said.

The teacher couldn't help but smile bitterly at this time and said: "Yes, this case is not difficult to solve, but at that time the most elite criminal investigation team was organized locally, and it took two months to find the murderer."

"The past two months should have been mostly wasted on placing the murderer on campus, right?"

The teacher's eyes suddenly widened and he asked in shock: "You think of the murderer outside the school so quickly?"

"Of course, because he came in and out through the vents. If he were a student in the school, he would have no way to hide under the surveillance. Only by being in the dormitory as soon as he entered could he kill four girls silently. At that time It's late at night, and the students in the school can't do it!"
