But Sun Qian didn't respond. Only then did Zhang Kang realize that Sun Qian was dead. He let the body frighten him to death. He was scared to death. He was also afraid that the police would mistakenly believe that he killed himself. .
At this point, the case seems to be clear.
Wang Luo left the room without saying hello, so that Guan Yuan didn't even know who was interrogating the prisoner. Lin Weiwei, who was beside him, quickly said that he was stabbed with a knife, and his mind was unclear...
However, just when everyone thought the incident was about to end, the case was once again thrown into chaos.
When examining the corpse, Wang Luo smeared a layer of white vinegar on the corpse, which is a means of examining the corpse.
"This time there are a lot of red marks on the back of the body"
"There are also very fine scars on the neck"
"What's going on? We didn't have this thing last time we came here?" Lin Weiwei asked in surprise.
Wang Luo remained expressionless and said, "This time I smeared white vinegar on Sun Qian's body. It can show some invisible scars on the body."
These red marks were all the scratches on Sun Qian's back when she was alive. If it was the wounds she suffered while she was alive, although the marks would not be obvious or even visible, they would only be visible if she was smeared with white vinegar.
"But Shao Kuan and Zhang Kang's confessions didn't mention it. No one said they hurt Lin Weiwei's back?"
"And why is the scar on this neck so thin?"
"Shao Kuan hit Sun Qian on the head, and Zhang Kang just grabbed Sun Qian's hand and argued."
But who did the injury on the back?
And on the neck
Wait, and Zhang Kang said that he just pressed his hand on the wound on his forehead...
Wang Luo opened the body again and observed the wound with a magnifying glass. Now the blood in the wound has become a blood clot, bulging on the forehead. There is no finger marks on the blood clot, and there is no sign of the blood clot being crushed at all. After the person died, The blood will stop circulating, as long as the hand is on the total blood clot, press it lightly, and it will immediately appear like a fingerprint, and the blood clot is now smooth and delicate, Zhang Kang is lying!
Wang Luo took the phone in one hand and told Guan Yuan what he found, and asked him to interrogate Zhang Kang quickly.
In the detention ward of the hospital, the lights on the roof were turned off. Guan Yuan had people bring four high-intensity desk lamps from the police station. These lamps are custom-made, and the light of one is extremely strong, let alone four pairs of lamps. When the person being interrogated is under the stimulation of strong light, it is difficult to organize their own thoughts, and the pressure will also increase, resulting in anxiety.
Today's Zhang Kang is no exception. The strong light makes him unable to open his eyes. The opposite is Guan Yuan, who is smoking a cigarette. He has already smoked half a box. The whole ward is full of smoke. The hospital would not let him. He is smoking, but the doctors are off work at this time, and several people on duty are also sleeping, so I don't care about him. Zhang Kang is an old smoker. This is in the hospital, let alone smoke, he can't smell it. , this will smell like a cigarette, just as cruel as eating a full Chinese feast in front of a beggar.
"Didn't you ask me, I said everything I said, what else do you want, can you turn off the lights, it's dazzling..." Zhang Kang covered his eyes with his hands, not daring to look directly.
Guan Yuan exhaled a cigarette ring, but did not answer, instead he picked up a desk lamp and approached Zhang Kang. The strong white light filled Zhang Kang's pupils. Zhang Kang's heartbeat was racing at this time, and he was also thinking, could it be the police? What do you know?
"You're not honest, I thought you were a tough guy. After I caught you, you didn't make excuses and said everything, but you also underestimated us. Come on, whether you can kill people!" Guan After Yuan finished speaking, he slammed the lamp on the table.
Zhang Kangdao: "I didn't kill people"
Guan Yuan smiled, tidied up his police uniform and said, "You explain, and tell us on the initiative, these are two natures, you should be smarter, say it yourself."
Zhang Kang strengthened his courage, stopped talking, and just spent time with Guan Yuan.
Guan Yuan's cell phone rang on the table, and it was Wang Luo's video call: "Zhang Kang, what's the matter with Sun Qian's back injury, didn't you say you found her dead and carried her into the refrigerator, But how do you explain the bruise on Sun Qian's back, Shao Kuan also said that there was no dispute with Sun Qian in the past few days, but the wound on Sun Qian's back was very thin, not like an ordinary bruise."
Zhang Kang was stunned, touched the wound on his face with his hand, and recalled what happened that day...
There is no doubt that Zhang Kang was lying before, thinking that he could hide it from the sky.
When he arrived at Sun Qian's house, Sun Qian had actually woken up from a coma. He was timid and wanted to use force against Sun Qian, but Sun Qian resisted desperately, and Zhang Kang used the fishing line he carried with him to restrain Sun. The scars on Qian's neck and Zhang Kang's face were caused at that time. Originally, the use of fishing line would leave marks on the neck. Although it was very shallow, it would still be discovered. In order to conceal the evidence, Zhang Kang took Sun Qian's The corpse was put in the refrigerator, because the low temperature in the refrigerator will make the scar on the neck attach a layer of frost, and as the temperature decreases, the trace will disappear.
This is also Zhang Kang's cleverness. He knows how to use the refrigerator to clear his own criminal evidence. However, Wang Luo still has a question. The scar on Sun Qian's back looks like a scar caused by being squeezed, but Zhang Kang did not show this scene in the confession. ah?
Lin Weiwei took a picture of the scars on Sun Qian's back with her mobile phone in advance. It felt like a cross, like a chessboard. What's going on? It was said that it was caused by accident. It's impossible. Such deep scars, Zhang Kang Shouldn't there be an impression?
Zhang Kang is probably the murderer
But what happened next made Wang Luo even more confused.
"I was too scared at the time, so I didn't take the fishing line. As for where the fishing line went, I can't remember." As soon as Zhang Kang's words came out, Wang Luo on the other end of the phone was surprised that he was not there. Finding something as important as a fishing line made Wang Luo's spine feel cold, which was a stain on his career.
Is the scar on the neck caused by the fishing line?
Fishing lines are now clues and evidence.
Guan Yuan was also stunned, hung up the phone, and called Xiao Wang, who was in charge of the on-site investigation, overnight, and told him to hurry over now. If you can't find the fishing line, don't go back to work at the bureau. On the one hand, three criminal policemen were called. , to give Zhang Kang the means, three shifts, and interrogation to prevent him from lying and tossing people.
Xiao Wang answered the phone sleepily. He was scolded at first, and then he drove to the apartment where Sun Qian was killed without washing his face. When he got there, he found that the lights were turned on, and he didn't need to ask to know that it was Wang Luo. With Lin Weiwei inside.
"It's the job of the criminal police to search the scene, you guys..." Xiao Wang was about to say that Wang Luo and the others had destroyed the scene, but Wang Luo was covered in isolation, with a mask on his mouth and a closed cap on his head. This detective needs to be professional.
Wang Luo was lying on the ground, searching for dead spots in the room with his eyes, for fear of missing something, Lin Weiwei, who was on the side, followed suit, and also lay on the ground. The two of them looked a bit funny. He smiled and asked Lin Weiwei, "How about you two learn tortoises?"
Lin Weiwei was not angry, but said seriously: "From the ground on a level plane, you can best observe the details that appear. What do you know? By the way, why don't you call a few people in the team and let you come alone?"
"What do you know, the more people there are, the easier it is to destroy the scene, and it's easy to leave behind your own hair, blood, and saliva. This is not good for the investigation work. I think three people are too many." Xiao Wang said.
Zhang Kang said that he did not take the fishing line, but there is no trace of the fishing line in the whole room. Lin Weiwei went to the refrigerator. The Samsung refrigerator with three doors has a lot of space. Except for the items in the refrigerator room, other things are still there. They were all taken out and looked empty. Lin Weiwei pulled out the latch easily. This is her habit. Since the refrigerator is no longer needed, don't waste electricity. There are several lines on the bottom of the refrigerator, one horizontal and one vertical. There is also the Samsung logo. Why is this pattern so familiar? It seems that I have seen it before. Lin Weiwei took out her mobile phone and looked at the photo. The scar on Sun Qian's back is not exactly the same, isn't it?
Understand, Sun Qian's back injury was caused in the refrigerator, but how was it caused by such a large force? Zhang Kang's strength will not be able to make such deep marks in such a narrow space, right?
Wang Luo also came over at Lin Weiwei's greeting and stuck his head into the refrigerator. He even asked Lin Weiwei to lock himself in outside. He wanted to try the feeling in the refrigerator. Lin Weiwei was 1.65 meters tall and 100 pounds. , Wang Luo himself is 1.73 meters and 120 pounds. In this big refrigerator, he can only hug his body, curl his legs, and dare not move. It is estimated that Lin Weiwei is similar to himself.
This feeling is really unpleasant, my body is terribly stiff, and I can't move around. If I turn around a little bit, my head will touch the shelf above: "Close the door tighter and see if it is completely closed." Wang Luo said to Lin Weiwei inside.
Lin Weiwei slammed the refrigerator door hard, and found that it couldn't work, and it still couldn't close. The gap was too big, and it couldn't close at all. Wang Luo got out and patted the frost on her body.
"How is it, senior, did you find anything?" Lin Weiwei took out a tissue and wiped the ice mist on Wang Luo's head. Wang Luo looked at Lin Weiwei up and down, suddenly put her hand on top of Lin Weiwei's head, and hugged Lin Weiwei.
