I am a super cop

Chapter 475 PI 【Seeking Monthly Pass】

Seeing several policemen stop at the same time, the old lady of the administrator was stunned for a moment, and looked at them with blurred eyes: "Comrade policeman, is there... is there any problem?"

Gu Chen didn't speak, and blocked the old lady behind him, and made a silent sign language.

At the same time, Officer Wang and Officer Ding took out police pistols, while Lu Weiwei and He Junchao took out shrinking batons.

Gu Chen took out the tear gas injector from the nine small pieces of equipment, threw it in a handsome spin, and firmly received it in his hand.

"Have you heard it?" Gu Chen asked in a low voice.

"I can smell it." Lu Weiwei nodded.

Officer Wang, Officer Ding and He Junchao also nodded one after another.

Only the administrator aunt was a little confused, hurriedly tugged at the corner of Lu Weiwei's clothes, and asked in a low voice: "Sme... what did you smell?"

"The smell of blood." Lu Weiwei said.

"Blood...stink? How...how could it be like this?" When the aunt administrator heard the smell of blood, she immediately took a few steps back in fright.

She quickly hid at the corner of the stairs.

Lu Weiwei took the key given by the old aunt and gave it to Gu Chen. Gu Chen slowly inserted it into the keyhole and twisted it gently.

With the sound of "click", the old wooden door was twisted open in an instant, Gu Chen dodged, Officer Wang and Officer Ding kicked the door open at the same time, and they rushed in successively with pistols.

"Don't move!"

"police."

The whole room was suddenly filled with noise, and everyone broke into the door, but it suddenly became quiet again.

When Gu Chen came to the room, he realized that a thin man was lying on the ground at the moment, with bloodstains all over his body.

The blood that flowed out condensed into a large bloodstain on the rough concrete floor, extending to the vicinity of the door.

It's no wonder that everyone who is naturally sensitive to blood still sniffed out the problem the first time.

Since the blood has long been coagulated, it disperses in the air, making people feel an unpleasant nausea.

Gu Chen hurriedly put away the equipment and put on white gloves to check the identity of the deceased. At this time, Gu Chen found that the deceased was exactly the same as the Zhang Lai that everyone had been looking for in the photo.

The decadent long hair, untrimmed beard, and haggard face all basically fit Zhang Lai's characteristics.

In addition, this was the room that Zhang Lai rented, so the deceased was Zhang Lai.

Lu Weiwei exhaled heavily, and said helplessly, "That's all right, the person was found, but it's just a corpse."

"How did Zhang Lai die?" Officer Ding curled his lips in the same doubt.

The person who made him unable to eat or sleep for the past few days was finally found, but it was a dead body, which immediately made Officer Ding feel quite frustrated.

After inspecting Zhang Lai's body, Police Officer Wang said cautiously: "This kid was stabbed to death with a knife."

"And judging from the current situation, Zhang Lai may have been dead for a long time."

"Where is the administrator?" Gu Chen hurriedly looked up, looking for the administrator's mother who led the way just now.

He Junchao quickly took a step back, and waved to the administrator aunt in the corridor: "Come here quickly."

It was also because of being overly frightened that when she walked into the room, she found a corpse lying on the ground, so the auntie administrator screamed in fright.

"What... what's going on here? How can there be dead people on the ground?"

"Don't be nervous." Gu Chen hurried to her side, pointed to the corpse on the ground and said, "This person is Zhang Lai who lives in your road administration apartment, you don't know him?"

"Yes...is that guy?" The aunt administrator swallowed her saliva immediately, stepped forward cautiously, bowed her body and took a few glances at Zhang Lai's appearance, and then said: "It's really him , How could he die? Impossible, when I saw him a few days ago, this guy was still alive and well, why now..."

Seeing Zhang Lai's tragic death, the administrator's aunt quickly turned around: "Oh my God, what a crime, it's not good where he died, but he was going to die in our road administration apartment, how can I rent this house from now on. "

"Let me ask you." Gu Chen saw that the administrator's aunt was a little relieved, and hurriedly asked, "When was the last time you saw Zhang Lai?"

"The most... the last time? Let me think about it." The administrator's face was stiff at the moment, she scratched her head with her right hand and thought over and over again, and finally said: "Yes, I remember, it was three days ago, the last time I saw him , It was one morning three days ago, when he went downstairs he was very flustered and touched me directly, and I reminded him to walk carefully."

"Since that time, I don't seem to have met him again. After all, he is also a new tenant. I don't know him very well, and I don't pay much attention to him."

"That is to say, after you met Zhang Lai three days ago, you never found any trace of Zhang Lai again, so you haven't checked the rooms of these people?" Officer Wang asked.

The administrator's mother frowned: "I said, Comrade Police, all the rooms here have been rented out, so of course I don't need to check them. If there are still extra rooms, and there are tenants who want to come and have a look, I will take them to the Walk upstairs."

"But the key is not to use it. The rent here is very cheap, and most of the tenants are construction workers who come here temporarily."

"So they are renting here, and I only need to collect the money, and I don't care about anything else, as long as I don't make trouble in the apartment."

Lu Weiwei roughly checked the apartment environment at the door, and then walked back to the room and said, "This is the same as the dormitory in the old school before. I have seen it. The people living here are very mixed, and many old people and children live there. Crowded in one room."

"That's right." The administrator aunt hurriedly said: "The location of our place is actually good, but it's about to be demolished, so the rent here is quite cheap, and there are more people renting here."

"Especially there are a lot of people from other places. On our side, dialects from all over the world are gathered together. It feels like there are people from all over the world. Usually, some people are fierce and scary, so I don't usually go upstairs."

After thinking about it, the aunt administrator hurriedly said again: "Oh, by the way, there are often people fighting in the corridors here, and the ones that make a lot of noise."

"Some people fight when they disagree. I heard one three days ago, but I didn't take it seriously, because there are a lot of people drinking and fighting here."

"Could it be that Zhang Lai died three days ago?" Police Officer Ding asked suddenly.

Gu Chen continued to examine Zhang Lai's body. After repeated searches and verifications, Gu Chen clapped his hands, stood up and said, "The deceased, Zhang Lai, died three days ago."

Looking at the surrounding environment, Gu Chen said again: "And the murderer is obviously a professional criminal. He didn't leave his fingerprints or footprints, and he also took away the murder weapon."

After entering the house, Gu Chen also conducted a detailed inspection of the interior of the house using his professional observation skills.

Officer Ding said in surprise, "Gu Chen, what is your basis? He died three days ago, is that correct?"

"That's right, it was three days ago." Gu Chen squatted down, pressed his fingers on Zhang Lai's body a few times, and then said:
"Actually, there are several ways to judge the time of death of a corpse. I learned these from Forensic Doctor Liu."

"Oh?" Seeing that Gu Chen has confidence in himself, He Junchao, who usually rarely has the opportunity to handle cases with Gu Chen, suddenly became curious like an elementary school monk, so he hurriedly asked him, "Which methods?"

"Look at the stiffness of the corpse." Gu Chen pressed the corpse again with his fingers, and then said: "Under normal circumstances, the corpse will stiffen within 30 minutes to 2 hours after death."

"Nine to 9 hours it's completely stiff, it softens after 12 hours, but returns to its original shape after 30 hours."

After thinking for a while, Gu Chen said again: "Of course, if the corpse is in the soil or water, or in low-temperature and dry conditions, it will be delayed, and it will be accelerated in high-temperature and humid conditions."

"But judging from the weather conditions in the past few days, it seems to have little impact."

Police officers Ding and Wang nodded frequently, and He Junchao also agreed, but soon he asked again: "It is indeed possible to judge only by the stiffness of the corpse, so what else?"

"The other thing is to judge based on the temperature of the corpse." Gu Chen stood up directly and said, "Generally speaking, within 10 hours after a person dies, the temperature of the corpse drops by 1 degree Celsius per hour."

"And more than 10 hours after death, the body temperature drops by 0.5 degrees Celsius per hour."

"There is also a judgment based on the purple-red plaques that appear on the skin under the corpse after death, that is, corpse plaques."

“尸斑通常在死亡后2小时至4小时出现，经过12小时至14小时发展到最高度，24小时至36小时固定下来不再转移。”

"So judging from this point, the deceased Zhang Lai's death time was at least 36 hours, but based on the stiffness of the body, I can conclude that his death time should be three days ago, which is the first time we searched for him. sky."

It was also after listening to Gu Chen's detailed explanation that He Junchao gave a thumbs up in admiration: "It seems that you, Gu Chen, have thoroughly understood Liu's forensic medicine. It turns out that the time of death can be judged based on these things."

"Then since he was killed three days ago, why didn't anyone know about it at that time?" Officer Wang felt a little puzzled, and quickly looked at the administrator.

The aunt of the administrator was stunned for a while, and quickly explained: "Didn't I just say that I just rent the room and check out. There are too many people living here, and some people often drink and make trouble."

"I have nothing to do. I usually don't go upstairs, and I don't know what happened upstairs, really."

After thinking for a few seconds, Lu Weiwei quickly asked her, "Then, among your tenants, who do you think is most likely to do such a thing?"

"This..." The administrator aunt was stunned again, and after thinking about it, she shook her head: "I'm sorry, comrade policeman, if I want to say who is the most likely, I don't want to talk nonsense."

"Anyway, the environment here is not good. Foreigners who want to develop in Jiangnan City for a long time will definitely rent a more reliable place."

"Our place is a place where the floating population lives temporarily. The rent is cheap. After all, the rent of the surrounding apartments is several times that of this place."

"So there are everyone, and I don't know much about these people, so I'm sorry, Comrade Police."

Looking at Zhang Lai's body on the ground, the administrator's aunt immediately wiped away her tears: "This child should be quite young, why is it gone? What do you call this?"

At this moment, He Junchao seemed to have discovered something new on the table, and he quickly called everyone: "Look at this."

Gu Chen was the first to come to the table, Zhang Lai's desk was full of manuscript paper, one of which looked like a letter, so Gu Chen held it in his hand and read out softly:
"He's coming again, getting closer, listen, footsteps, ta... ta... ta..."

Zhang Lai just wrote this line in scribbled handwriting, and when Gu Chen continued to search for other manuscript papers, he didn't see the text anymore.

Lu Weiwei was also very puzzled, she hurriedly asked Gu Chen, "It's obvious, it's likely that Zhang Lai knew something, or before he died, he knew that someone was coming to him, so he wrote down what he said on the manuscript paper. I heard."

"Is this guy writing horror novels?" He Junchao felt very strange, pointing to the words on it and said, "Look, although it's just a sentence, it seems that someone is really approaching outside the door."

"You say, does this guy have delusions, mistaking the footsteps passing by the door for someone coming to him?"

Gu Chen shook his head: "I don't think so."

"I don't think so either." Lu Weiwei also said, "What do you think, who wants to stab him? It means you know him."

"Since we know each other, we will definitely come to him, but from this sentence, it can be seen that Zhang Lai obviously knows that someone is coming to him, so he is extremely nervous."

"Especially this sentence: He is here again, the emphasis is 'again', what does this mean? It means that this person has already been here once."

After listening to Lu Weiwei's analysis, Officer Wang couldn't help admiring him: "It seems that after following Gu Chen for a long time, people will also become smarter. That's right, the word 'again' can explain the problem very well. It seems that Zhang Lai has something to tell us." .”

"He may have known this murderer, but judging from the words he left on the manuscript paper, he seems to be very afraid of this murderer, and he seems to know that this person is not good."

"Senior Brother Wang is right." Gu Chen also took the manuscript paper and looked at it for a long time, then looked up and looked around: "If Zhang Lai intentionally uses the words on the manuscript paper to tell us that someone is going to harm him, then he must return Other leads will be left."

Looking up at the administrator's aunt, Gu Chen asked her: "Auntie, is there anyone with disabilities in your apartment?"

"Yes...there is one." The administrator's aunt was also a little curious about Gu Chen's question, but there happened to be such a person in the apartment, so she hurriedly said: "His leg seems to be broken by someone with a steel pipe in a group fight. Yes, I also casually asked him when he moved into the apartment."

"Then he should also live on this floor, right?" Gu Chen asked again.

"Yes, it's not far from here." The administrator aunt was full of doubts, and quickly asked Gu Chen, "How do you know?"

Gu Chen didn't answer directly, but continued to ask: "Auntie, let me confirm one more question with you, does the person with inconvenient legs live in room 314?"

"Ah?" Also startled by Gu Chen's conjecture, the administrator's aunt was stupefied, she didn't know what to say: "You... how do you know? This person with inconvenient legs is really...really They live in Room 314."

Now it was the turn of Officer Wang, Lu Weiwei, Officer Ding and He Junchao to be dumbfounded.

Everyone showed a surprised expression, feeling a little unbelievable.

"Gu... Junior Brother Gu." Lu Weiwei stared straight at Gu Chen, and asked him weakly, "This...how do you know this?"

"It's very simple." Gu Chen felt that there was no need to hide it, and said directly: "Because of the words on his draft paper, you can read."

Gu Chen pointed to some of the words, and said, "This is actually a note left by Zhang Lai before his death. He walks on crutches."

"That's right." Police officer Wang suddenly realized, and he hurriedly said, "We also passed the corridor just now. The footsteps on this kind of ground are very small, so how could there be the footsteps of 'tap...tap...tap'? It is obviously emitted by other substances, and I agree with Gu Chen's crutch."

"So that's the case." Officer Ding also nodded thoughtfully, but soon he asked Gu Chen again: "But even if you know that the other party has a handicap, how do you know that he lives in room 314?"

"Zhang Lai told me." Gu Chen said.

"Zhang... Zhang Lai told you?" Several policemen were confused at the same time, and everyone looked at each other in blank dismay, feeling a little confused.

Gu Chen didn't let it go, he stepped forward a few steps, and tapped Zhang Lai's arm with his toe: "Look, what does Zhang Lai have under his command?"

"A... circle?" Lu Weiwei looked up at Gu Chen, and said, "It's a circle made of blood."

"That's right." Gu Chen turned to face everyone, and said, "Zhang Lai is a genius in Mathematical Olympiad, as we can tell from Yuan Shaogang."

"And this person is paranoid about mathematics, likes to delve into mathematics problems, and has obsessive-compulsive disorder. Do you think he will draw circles boringly before he dies?"

Everyone looked at each other and shook their heads.

Gu Chen snapped his fingers and said, "That's right, he won't. A math-obsessed person like him is just using circles to tell us where his murderer is."

"Given his obsession with mathematics, I deduced that he must be trying to tell us in terms of pi, and pi is 3.14, so I concluded that the murderer should live in room 314."

Also listening to Gu Chen's explanation, everyone seemed to be enlightened.

Officer Wang stared at Gu Chen's face, without breathing for a few seconds, he asked alertly: "So, the murderer is in room 314 right now?"

"Go and see." Gu Chen said.

Officer Ding couldn't wait any longer, and immediately patted He Junchao on the shoulder: "He Junchao, let's go take a look."

After speaking, the two took the lead and rushed out of Zhang Lai's room.

Room 314 and Zhang Lai's room are in the same corridor.

At this moment, before the administrator aunt could catch up, the two began to knock on the door "duk tuk tuk".

"Who is it?" A rough voice came from inside the house.

He Junchao didn't reply, but turned to look at the administrator's aunt.

The auntie administrator understood, and hurriedly shouted: "It's me, I'm the administrator, please open the door."

"What do you want from me?" The tenant in the house seemed unwilling to open the door, and was somewhat alert.
