Yin Shun was the one who answered the professor most satisfactorily among these few students. He made a bold inference without losing the basis, and he had mastered the information in detail, and he had fully studied the case.

The professor was a little interested in him, and continued to ask: "Then why do you think the murderer deliberately drenched the corpse with industrial wastewater after committing the crime?"

"If it's not to destroy the DNA, it's to cover up the smell of blood and prolong the time it takes for the body to be discovered." Yin Shun's answer surprised everyone present. They had analyzed the murderer's behavior from a psychological and professional point of view, but no one ever did it. analyzed at such a simple level.

"The body was discovered by a woman who went to the toilet the next day. Before the body was discovered, the public toilet administrator who was already on the job didn't notice anything unusual. Isn't it strange?" Yin Shun first asked a question, Afterwards, according to the analysis, "the deceased was killed around 02:30 in the morning, and the murderer dismembered and reassembled the deceased. These efforts took the murderer two hours or even a little more time. The murderer should have completed the entire crime process at five in the morning." It's 05:30, and the public toilet administrator goes to work at six o'clock. If the murderer hadn't used industrial wastewater to cover up the bloody smell in the public toilet, the administrator would have noticed the abnormality at six o'clock on the day of the crime, so the murderer would not have enough time to stay away from the crime scene .Because behind the public toilet is the ditch where the factory discharges waste water, so the administrator will not be surprised to smell such a pungent smell of industrial waste at his post, which is why he did not find the corpse in time, and thus gave the criminal enough to escape time."

"Why do you think the murderer did this to prolong the time before the body was found?"

"Just because he carefully drained the deceased's blood into the drain using the urinal. The body will bleed a lot when it is dismembered. If the murderer does not deal with the excessive blood, then the blood will overflow the public toilet, and the administrator will promptly The abnormality was found in the public toilet. The murderer took this into consideration when dismembering the corpse, so most of the blood of the deceased flowed into the urinal."

"His timing is so accurate? So are you sure you can escape smoothly?"

"No criminal can be sure that he can escape smoothly." Yin Shun said, "Every time he escapes smoothly, in addition to three points of wages, there is seven points of luck. In that era, technology was not developed, and the police relied on clues at the scene and physical evidence to investigate. Therefore, the police are easily distracted by some redundant factors, and the police force cannot be fully concentrated. If the murderer has a detailed plan, he can easily escape the police's pursuit."

All the students present were silent. They were speechless after listening to Yin Shun's series of analysis. Even the professor was a little surprised by this freshman.

The professor wanted to ask Yin Shun more about his views on this case, but the class was fair, and no matter how good Yin Shun's views were, he had to give other students a chance to answer.

The professor reluctantly asked Yin Shun to sit down, and asked the students one last question: "I will ask the students one last question. If you were asked to investigate this unsolved case today, how would you go about finding the murderer?"

At this moment, the bell rang for the end of get out of class, and the professor said: "I leave this question as homework for you."

Disagreement among students in the classroom resounded again, and some students joked: "Maybe after this typhoon, the spider killer will reappear in the rivers and lakes."

Xia Huai's thesis on the analysis of the characteristics of the victims could not produce the effect that the tutor wanted. The tutor thought that Xia Huai had ideas and a qualified writing style, but maybe as a man, he couldn't think about the problem from a female perspective, so he expressed it Thoughts always overemphasize or demean female victims.

In order for Xia Huai to find a balance between the victim's strength and weakness, the tutor took him to meet someone.

Xiao Mei, the victim of the island series in 2004, is the last victim and the only survivor of the series so far.

Xiao Mei was originally a female soldier. In 99, she was blinded by a shell and had to retire.Xiao Mei's parents passed away in 00, leaving her and her younger brother to depend on each other.The siblings live on government subsidies and live in poverty. In 02, Xiao Mei sold her house and lived with her younger brother in a stone house in Antong District.

On August 2004, 8, the criminal who was later identified as the murderer of the pirate series sneaked into Xiao Mei's home through the window at two o'clock in the morning with a kitchen knife.Xiao Mei's 29-year-old brother happened to get up to go to the toilet in the middle of the night, and ran into a criminal who was plotting evil.

Under her brother's yelling, Xiao Mei woke up from her sleep. The criminal panicked and wanted to deal with her young brother first.This choice was obviously wrong. His action of attacking his younger brother stimulated Xiao Mei. At the same time, he also underestimated Xiao Mei's attack power.

Xiao Mei quickly drew out the samurai sword on the wall, and slashed the criminal's back with one knife, and the criminal fled with the top wound.The younger brother escaped death by chance, but his left cheek was scratched by a kitchen knife, leaving a permanent scar.

Xiao Mei is blind and could not see the face of the murderer on the day of the crime. Xiao Mei's younger brother was too young and was so frightened at that time that he couldn't even express himself clearly. When he grew up, he selectively forgot the criminal's appearance. .

It may be because of being hacked by Xiao Mei, or it may be that since 04, all areas of Haidao City have been fully monitored. The murderer of this series of cases did not continue to commit crimes after the failure of Xiao Mei's case.

The instructor brought Xia Huai to see Xiao Mei. After more than ten years, Xiao Mei was almost 40 years old, and she didn't like to talk, and she didn't like to talk about the incident back then.Just for the sake of being taken care of by Xia Huai's mentor, I am willing to chat with Xia Huai.

There are several photos of Xiao Mei and her younger brother on the bookcase at Xiao Mei’s house. From 1999 to 2010, Xiao Mei’s younger brother gradually opened up, and the scar on the left cheek was enlarged with the opening of the skin. Xia Huai raised her eyebrows and asked, "Xiao Hai is your younger brother?"

Xiao Mei, who is not very talkative, responded: "Has he committed another crime?"

Xiao Mei's slashing of the murderer made her famous, and all the women on the island regarded her as a hero.Xiao Hai grew up ignorant and often committed crimes. Sometimes he cheated the old woman of ten or twenty yuan, and sometimes he secretly ate apples from other stalls.

It's not that those people really don't know, but because his sister is Xiao Mei, they don't pursue him.

"No, he's fine." Xia Huai wasn't lying, he hadn't seen Xiao Hai for a long time, Xiao Hai often came out to commit crimes, since the fruit stand robbery incident, he disappeared, and he hasn't seen anyone for several months .

Xiao Mei, who was blindly picking up vegetable leaves sitting on a wooden chair, sighed and said, "He hasn't come to see me for a long time. If you see him, remember to ask him to come and see me."

On the eve of typhoon Moran, there was already a lot of wind blowing around the island. After finishing talking with Xiao Mei at five o'clock, Xia Huai hurried back to the school dormitory as the wind was getting stronger.

He took out the keys in one hand and answered the phone that just rang with the other.

"Brother, I...I..." Xia Nan on the other end of the phone faltered, as if she was hiding something.

Xia Huai picked up the key with one hand and was irritated: "What's the matter? Tell me quickly, don't say I'll hang up."

"I have a boyfriend." Xia Nan finally said this sentence.

"What?" Xia Huai was so frightened that the key she had just picked out fell down and got mixed up with other keys.

Xia Nan repeated loudly: "I have a boyfriend!"

"Who is so blind?!"

Xia Nan said angrily: "Are you still my brother! I'm dead!"

"Wait a minute, what does he do? How old is he? Where is he from? What's his name?"

"You'll know next time we go out for a meal together, and I'll just tell you, that's it!" Xia Nan quickly ended the call.

Xia Huai was depressed looking at the beeping interface of the mobile phone, a gust of cold wind suddenly hit, and Xia Huai snarled.

His dormitory was at the end of the corridor, and the windows at the end were not closed tightly. The wind was strong outside the window, and the leaves were rustling.

Looking at the thin saplings that were blown upside down and the broken branches, Xia Huai had a premonition that this year's typhoon would be different from usual.

Xia Huai put the phone in his pocket, and dropped the key on the ground without grasping it. A person came behind him, and squatted down to pick up the key for him.

Seeing the visitor, Xia Huai was pleasantly surprised: "Why are you here?"

"The dormitory is not so strictly controlled during the holidays. I'll come to you." Yin Shun opened the dormitory door for him.

The two walked into the dormitory, Xia Huai asked Yin Shun: "What class did you have today?"

"Crime analysis class took the island serial murder case as a case." Yin Shun closed the door and said.

Xia Huai's eyes lit up: "What a coincidence, what do you think I did this afternoon?"

"Ok?"

"I went to see the only survivor of the series in 04, the woman who stabbed the murderer. My mentor took me to see it."

"Really? What were you talking about?"

Xia Huai shook her head and sighed: "She is almost 40 years old, and she doesn't want to talk, so she responded to my question. But it can be seen that that incident didn't have much impact on her. Her mentality Played well."

"Really?" Yin Shun stood by the window, looking at the wind-ravaged land outside the window, as if thinking deeply.

Xia Huai glanced at him: "I watch those people training in the back mountain by the window every day, why have I never seen you?"

"Our class only trains in the playground, never here." Yin Shun turned around, took off his police uniform jacket and hung it on the door.

Xia Huai pretended to be nonchalant and let out an "oh", and closed the curtains that had hardly been drawn, and seemed not so interested in the back mountain.

Yin Shun stared at the police uniform hanging on the door without saying a word for a long time, then suddenly said: "I want to investigate this case."

"what?"

"I want to investigate the island serial murder case."

Xia Huai was stunned for a moment, and asked: "The case is unsolved, what else can we find out? The police station has put this case on hold."

"why?"

"The special case team that handled this case in 09 had internal problems. After the internal problems were resolved, the team disbanded. After that, the police station didn't intend to reorganize the special case team, so no one continued to investigate this case." This information is also shared by Xia Huai. I got it from my time managing the archives.

Yin Shun was thoughtful. At this time, the professor who was teaching today in the class sent a message: "If you were asked to investigate this unsolved case today, how would you go about finding the murderer"?After you finish the homework, please send the homework to my mailbox.

Yin Shun immediately edited an email and sent it to him. In the email, only four letters "Y-STR" were written.
