，

When he opened the door of Zhao Qiang's living room, the fireplace in the living room was still burning, and next to the fireplace, there was a high-end soft chair.

Zhao Qiang also saw that after the police entered the door, they scattered to prepare for a search, so he smiled awkwardly: "My house was also built not long ago." ”

"Because my business is in the city, I rarely come to live because the weather is so cold, so I always feel that it is not warm enough. ”

So I went outside and bought some firewood from the villagers, and I built a fire in my own house to learn the way of life of Europeans and Americans. ”

"Do you like the lifestyle of Europeans and Americans very much?" Gu Chen asked him.

Zhao Qiang smiled directly: "I can't talk about whether I like it or not, but I am particularly touched, because European and American country houses have a fireplace and a big chimney, so it's not convenient for Santa Claus to throw gifts at home, hehe." ”

Gu Chen ignored Zhao Qiang's humor, but walked directly to the fireplace, looked at the raging fire burning inside, and then sat on this high-end soft chair, quietly looking at the fire in front of him.

Seeing this, Officer He originally wanted to go over and say a few words, wanting Gu Chen to find clues first, and then come to the fire.

But before he could say anything, he was directly stopped by Comrade Wang next to him.

Officer Wang shushed at Officer He and said, "Leave the fireplace to Gu Chen, let's take a look around and see if there are any new clues." ”

"Okay. "The first time I saw such an investigative officer, Officer He was a little fresh.

If the new comrades in his institute dare to be lazy like this, he will sit on the soft chair and roast the fire when it is time to investigate, and Officer He will not hesitate to give him a jio.

But then again, maybe everyone's approach to investigation is different.

For example, Gu Chen, these clues before were sorted out step by step by this kid through subtle investigation.

It is impossible not to admire.

After all, in such a short period of time, the seemingly clueless cases can be integrated little by little.

If you have to change to someone else, you may not be able to do better than Gu Chen.

Seeing Gu Chen sitting there quietly meditating, coupled with Officer Wang's persuasion, Officer He didn't say anything, and went directly to other corners to continue searching.

Seeing that everyone was busy, the host Zhao Qiang, who had been standing in the middle of the living room, was a little embarrassed, and he didn't know how to communicate with everyone for a while.

So he went to the corner of the living room and brought a tea set to make tea for everyone.

"Could it be that the corpse is placed here?" Gu Chen squinted, looking at the floor next to the fireplace, there were obvious traces of wiping.

But from this point alone, it is not easy to judge the location of the corpse at all.

After all, wood is burned in the fireplace, and Zhao Qiang is in the yard, teaching firewood to gasoline and then burning, and bringing it all the way to the closet in the living room, which will inevitably be placed in front of the fireplace.

It may also be possible to clean up firewood dirt.

Thinking of this, Gu Chen stood up directly, then squatted in front of the fireplace and sniffed the surrounding smell.

After that, Gu Chen lay on the ground even more exaggeratedly, and began to smell the smell against the ground.

This made Zhao Qiang, who originally came to deliver tea with a paper cup, couldn't help but shake his wrist, and the paper cup containing tea fell directly in front of Gu Chen.

Tea splashed on Gu Chen's face......

"Ah, I'm sorry, I'm sorry comrade police, my hands are too cold, a little stiff, I'm sorry. ”

Zhao Qiang hurriedly walked over, and after looking left and right, he was about to get a tissue to wipe Gu Chen.

"No hassle. Gu Chen raised his head, turned around and asked Zhao Qiang, "What did you put on this floor tile before we came here?"

"Huh?" was also directly hit by Gu Chen, Zhao Qiang's whole person was stunned for a moment, and then he forced a smile and said: "Before, I let go of some firewood and stained the floor tiles, so I ......"

"So you dragged it with a mop, right?" asked Gu Chen.

Zhao Qiang seemed to be tortured by his soul, and his stiffness turned into the sky, so he nodded weakly: "Yes...... Yes, you have to clean up the floor if it gets dirty, don't you?"

"Where's the mop, can you show me?" Gu Chen chased after him and continued to ask.

Zhao Qiang looked a little embarrassed at the moment, but he still agreed with a smile: "Put the mop outside, then you come with me." ”

Gu Chen looked left and right, and followed directly behind Zhao Qiang.

Seeing this, Lu Weiwei didn't make a sound, and followed behind Gu Chen, and the three of them walked through the hall together and came to the kitchen.

At this moment, Zhao Qiang opened the side of the kitchen, pointed to the mop placed on the steps of the door, and said, "Just ...... Yes, there it is. ”

"Thank you for your cooperation. Gu Chen walked over directly, pushed Zhao Qiang away, and then took the mop in his hand.

At this time, due to the water stains on the mop and the cold outside, the rags of the mop directly froze into ice lumps.

"Frozen Senior Brother Gu. Lu Weiwei stretched out her hand, and the whole strip of cloth was hard.

"It doesn't matter. Gu Chen didn't think much about it, he walked directly inside with the strip of cloth and returned to the location of the fireplace just now.

At this moment, the flames in the fireplace were still very large, and Gu Chen put the frozen rags on the mop close to the flames and let them slowly soften.

After searching in the living room to no avail, Officer Wang and Officer He also discovered Gu Chen's operation one after another.

After the two looked at each other, they also drove to Gu Chen's side.

Everyone gathered around the fireplace, slowly waiting for the rags to soften.

Zhao Qiang, on the other hand, stood aside, his eyes fluttering, and he seemed to be even more anxious than Gu Chen.

"Gu Chen. Officer He didn't know what Gu Chen's intentions were, so he asked him lightly, "What are you doing here?"

"Bake the mop. Gu Chen casually turned the mop in his hand, letting Officer He know the current state of the mop, and said, "On the floor tiles in front of the fireplace, there are obvious traces of being wiped by the mop. ”

Hearing this, Officer He immediately understood what Gu Chen meant, so he didn't ask anymore, but just looked back at Zhao Qiang who was standing behind everyone.

Zhao Qiang was quieter than everyone imagined.

The whole person stood there motionless, as if he was thinking about something.

It didn't take long for the frozen strips of mop cloth to be softened by the fire.

Gu Chen put on white gloves, put the strip of mop cloth on the tip of his nose and sniffed.

The smell of the mop that had been baked by the fire was very strong, and a faint smell of blood was clearly beginning to appear in the air.

Moreover, Gu Chen found from the frozen strips of mop cloth that some of the strips of cloth had traces of blood donation stained red.

This made Gu Chen even more certain of his previous inference......

On the floor, there must have been some bloody object that had been spared before.

"Yes...... Does it smell, does it smell of blood?" Lu Weiwei, who was closest to Gu Chen, was the first to shout.

When Officer Wang and Officer He heard this, the two of them moved forward one after another, and after some testing and identification, they obviously made the same discovery as Lu Weiwei.

"That's right, why is there blood on the strip of cloth? and, judging by the smell, it should not have been long. Officer Wang glanced at Officer He.

Officer He glanced at Zhao Qiang behind him......

Zhao Qiang couldn't help but take two steps back at this time, and his expression was obviously sluggish.

However, he quickly calmed down, and before the police asked, he directly took the initiative to confess: "That's the case, I bought some ingredients a few days ago, and I wanted to sit in front of the fireplace and have a barbecue." ”

"You also know that since the wood costs money and is poured with gasoline, this cost, if it is used exclusively for heating the fire, it will be too wasteful!"

"I, Zhao Qiang, am a countryman, and I have known that resources are fully utilized since I was a child, and the design and structure of this house, I have also considered it, and I can grill and barbecue at home. ”

"And the bloodstains?" asked Lu Weiwei.

"It was me who killed the chickens in front of the fireplace, and I splashed blood on the ground when I cleaned up, so I cleaned it up with a mop, this ......"

Glancing at the kitchen, Zhao Qiang hurriedly said: "If you don't believe this, you can go to the kitchen to take a look, there are still some fresh chicken feathers in the trash can." ”

Just when Zhao Qiang's words fell, Gu Chen shook his head and directly denied his statement.

"Mr. Zhao Qiang, I noticed the chicken feathers in the trash can you just mentioned, this is obviously not today, and of course it will not be yesterday. ”

"Judging from the state of the chicken feathers, it doesn't seem to be new, and it can be concluded that it was three or four days ago, or more. ”

Glancing at the mop in his hand, Gu Chen directly put the soft strip of rag on the tip of his nose and sniffed it, and said, "But the blood stains on the strip of rag seem to be fresh, and the time should be in these two days." ”

"And ......," Gu Chen said here, his sharp eyes staring at Zhao Qiang in front of him.

This made Zhao Qiang stay there alone, but he didn't dare to look directly into Gu Chen's eyes.

"And this kind of blood is not chicken blood at all, and there is no fishy smell of chicken blood. ”

"So, you're lying. ”

"I ...... I didn't. Being directly angry by Gu Chen, Zhao Qiang's whole person was not good, and his face turned blue and said, "Comrade policeman, this is ...... It's got to be chicken blood, really, you must be mistaken. ”

"Did I make a mistake or did you make a mistake?" Gu Chen went directly to the front two and forced Zhao Qiang into the corner.

"Mr. Zhao, you may not know my identity, then I'll tell you, I'm Gu Chen from the Furong Branch, Criminal Investigation Group 3. ”

"As for the identification of blood, I think I should be a little more sensitive than ordinary people. ”

In order to show his modesty, Gu Chen specially gestured with his finger to the so-called little bit.

Lu Weiwei also sniffed it, so she hurriedly walked to Gu Chen's side and said, "That's right, what Senior Brother Gu said is not wrong at all, you are not chicken blood at all." ”

"Anyone who has ever killed a chicken knows that the smell of chicken blood has a fishy smell, and the smell is relatively strong, but you don't. ”

"If you want to distinguish bloodstains, I, Lu Weiwei, also have some capital to nag you a few words. ”

"I ...... I. Zhao Qiang was able to calm down and communicate with the police calmly.

But after Gu Chen exposed the bloodstain scam, Zhao Qiang was also panicked.

He hurriedly looked at Officer He behind Gu Chen, took the initiative to walk up to him and said, "Officer He, I'm ...... I think this must be a misunderstanding, you people came to my house for no reason, just to discern this, what the hell are you trying to do?"

"Investigate the killer who killed Dr. Liu. Officer He did not shy away from informing him of the purpose of everyone's visit.

But Zhao Qiang disagreed: "What Doctor Liu? What murderer? Why can't I understand what you are saying?"

"You don't understand, do you?" Gu Chen came to him again and took the initiative to explain: "Then I'll tell you, just two days ago on the night, Dr. Liu, who was on call, was hit and killed by a car when he left the patient's home. ”

"Bump...... Crashed to death?" Zhao Qiang was stunned for a moment, and said in shock: "This ...... ......That's too bad, isn't it? Then this driver is not virtuous enough, is it because the vision is not good at night?"

"If it's a bad sight, it's okay to say, but if the driver is drunk driving, it's completely different in nature. Lu Weiwei also continued to add.

Gu Chen said: "The driver who caused the accident, before hitting Dr. Liu, was on a straight road, hit a waste billboard on the side of the road, and five minutes later, he hit Dr. Liu again. ”

After killing Dr. Liu on the side of the road, in order to evade responsibility, he deliberately threw Dr. Liu's battery car into the roadside canteen. ”

He then loaded Dr. Liu's body into a car and took him away from the scene. ”

"Huh. Zhao Qiang looked at Gu Chen angrily, shook his head left and right, and said, "Although this driver is hateful, what are you looking for me to do?

Gu Chen smiled: "Didn't you do it? Then why is it so coincidental, I see that in the corner of your yard, there is still a car seat cushion?"

"This ......" Zhao Qiang was speechless for a moment, but when the words came to his mouth, he suddenly stopped, and he couldn't speak for a long time.

"Nothing more?" Gu Chen raised his eyebrows and continued, "Then can I understand it like this?"

"You loaded Dr. Liu's body into the car, met your house, and then bought gasoline overnight to accelerate the burning of wood to bake Dr. Liu's body. ”

"Because you know very well that at this stage, the corpse will accelerate the rate of decay due to the high temperature. ”

"You want to give the police a difficult debut problem, that is, you don't want the police to know when the deceased Dr. Liu died. ”

"You also know that even if the police eventually find Dr. Liu's body, it will be difficult to find the first crime scene if the time of death is not accurate. ”

"And if you don't find the first crime scene, it may be more difficult to track you down than to climb to the sky. ”

"So you use the fireplace in your home, not for grilling, but for baking corpses. ”

"Later, in order to avoid the police from finding clues, you cleaned up the blood stains in front of the fireplace and cleared the seat cushions in the car, in order to avoid being found by the police The blood stains, right?"

"Huh. Listening to Gu Chen's series of questions, Zhao Qiang, who was forced into a corner by Gu Chen, could only laugh dryly, and said with a smile: "Comrade policeman, what you said seems to have happened in real life, but these are your speculations and cannot be used as evidence." ”

Gu Chen also smiled when he heard this, and couldn't help but shake his head and said, "So far, your Mr. Zhao still doesn't admit his guilt?"

"That's okay, you may not know, we have found the first scene, and we have also found Dr. Liu's battery car, and some blood stains have been extracted at the first scene. ”

"If I'm not mistaken, then the bloodstains on this rag will match the bloodstains we found at the site of the first crime, and these bloodstains will definitely match Dr. Liu's bloodstains. ”

Speaking of this, Zhao Qiang suddenly stood a little unsteadily.

He couldn't help wiping the cold sweat from the corners of his forehead, like a frightened little animal.

Lu Weiwei on the side didn't talk nonsense, and said directly: "Since Mr. Zhao wants evidence, then we have to fulfill it, otherwise, please trouble Mr. Zhao to go back to the bureau with us, and then wait for our city bureau technical department and forensic identification to take over, what do you think?"

"This ......" Zhao Qiang's whole person was about to collapse.

Gu Chen couldn't help but shake his head, walked to his side gently, and whispered close to his ear: "Mr. Zhao, your off-road vehicle parked in the yard is good, I see that the bumper is quite strong." ”

"I ......" Zhao Qiang was stunned for a moment, but at this time he suddenly realized: "Yes, since you said that I hit someone, then why is my bumper okay?"

"Hmm!" Gu Chen took a step back, turned his head to Officer He and said, "Then trouble Senior Brother He, go to the nearby auto repair shop to investigate, and see if Mr. Zhao's car has changed the bumper in the past two days." ”

"Smack!"

Speaking of this, Zhao Qiang's legs were weak, and he sat directly in the corner.

......

......

7 p.m.

Furong Branch, Criminal Investigation Group 3.

Lu Weiwei hung up the phone in her hand, then came to the printer, paused to print the document she had just printed, buckled it with a binding machine, and then came to Gu Chen with a happy face: "Senior Brother Gu, the materials you want are ready." ”

And Lao He from the police station also called, proving that Zhao Qiang had come to the store to change the bumper in the past two days. ”

"That's it. Gu Chen smashed his right fist on his left palm, and asked, "Then have they investigated, what did Zhao Qiang do at night two days ago?"

"It's been investigated, and it's all been investigated according to your request. Lu Weiwei smiled diligently.

"What?" Gu Chen asked.

"What else, Lao He's investigation found that this Zhao Qiang was having a dinner with some business partners two days ago. ”

"Because he had made a big deal that day, he was very happy and drank a lot. ”

When he left, he didn't listen to his friend's persuasion to ask for a price, but just said that he would take a break and drive away by himself after he sobered up. ”

"Because I went to the countryside and it was dark, Zhao Qiang thought that he would drive slowly and there should be no big problem. ”

"That means that Zhao Qiang was indeed drunk driving that day?" Gu Chen asked.

Lu Weiwei nodded: "From the monitoring of the hotel, it can be seen that Zhao Qiang did take a short break in his off-road vehicle after separating from his friends, and then drove away, which was undoubtedly drunk driving." ”

"It's amazing. "The case has been investigated so far, and Gu Chen is already very satisfied.

With these clues, it is basically impossible for Zhao Qiang to quibble.

Gu Chen said with joy on his face: "Then now, it's time for Gao Chuanfeng's blood test, if the first crime scene, as well as the blood stains on Zhao Qiang's mop at home, can match the blood of Dr. Liu, and the three blood will be one, then Zhao Qiang can really cry and faint in prison." ”
