Serious Crime Unit 1

Chapter 488 Unknown Male Corpse (6)
When she took it over and took a look, her face instantly lost color and became as pale as a dandelion. Tears burst out from her eyes: "Husband, why did you leave me alone like this?" Then she started sobbing. The cry was not loud, but it was enough to impress anyone. people.

"Are you sure the person in the photo is Wu Yijun?" After Jiang Yiming comforted her and saw that she slowly stopped crying, he started to ask her.

"Yes, it's definitely my husband!"

"Well, people cannot be resurrected after death, so please show your condolences and obey. In order to let Wu Yijun rest in peace under the clouds, please cooperate with us to arrest the murderer."

"What do you want me to do?" she asked, raising her face full of tears.

"We will continue to investigate Wu Yijun's study." Although the deceased's ten fingers were cut off and there was no way to compare the fingerprints, the murderer forgot that people's palm prints are also unique and exclusive, because facial image reconstruction cannot reach It is 100% consistent, so palm prints must be extracted to confirm.

"Okay, I'll open the door for you." Huo Qingqing was wearing tight black clothes and black pants. Even her shoes and socks were black.It was as if she had been expected to be a widow.

Zhou Ting took out a magnifying glass and looked at Wu Yijun's desk and saw several palm prints.Sprinkle titanium dioxide powder on the palm prints and brush it a few times with a small brush. The two palm prints will appear clearly before your eyes.Then use a SLR camera to take a photo of the fingerprint, then take out professional transparent tape and gently stick it on it.In this way, a palm print will adhere to it.

Zhou Ting compared the extracted palm prints with the palm prints of the deceased. After a while, the comparison was successful and it was confirmed that the deceased in Blue Home was Wu Yijun.Once the source of the corpse is found, solving the case becomes twice the result with half the effort.

Everyone is happy, but Jiang Yiming is not optimistic, because the murderer not only set up a hurdle, but may also have set up many obstacles.

"Luo Jin, why is the DNA of the deceased different from the DNA extracted from the cigarette butts in Wu Yijun's study?" Jiang Yiming did not understand these two contradictory things.

"This...I don't quite understand this...let me think about it, maybe the murderer drained the blood of the deceased and then injected it with the blood of others, and I used the blood of the deceased to make DNA, so, with Wu Yijun The DNA doesn't match." Luo Jin was a little anxious and sweat broke out on his forehead.

"Why are you anxious? It's not your fault... The blood volume at the scene was about 5000 ml. This is an approximate blood volume. If your hypothesis is true, then where did the blood of the deceased go?" Jiang Yiming still didn't know. understand.

"It should have been put into a bucket by the murderer, taken away and dumped."

"The murderer who knows how to use other people's blood to interfere with our investigation must be a knowledgeable person, right?"

"Yes, the murderer should be a forensic scientist, criminal police officer, doctor, or biological researcher." Xiao Ke answered.

"I think it should be a doctor. Only a doctor can get other people's blood from the blood bank."

"No, it could also be underground blood traffickers. The underground blood smuggling in our city is rampant. There are many channels to buy other people's blood. I have tested it and found that the blood that interfered with ours is from the same person. We have to buy it from one person all at once. It is impossible to draw so much blood from a human body, and it would take at least five attempts to draw it."

Luo Jin is the chief prosecutor, and he is inevitably a little annoyed when the murderer plays with him like this. This would not be possible if the deceased's skin was used to make DNA.

Of course, you can't blame him. Most forensic doctors will use the blood of the deceased to make DNA, because this method is the easiest.The deceased's blood was drained while he was in a coma, and then someone else's blood was injected into him. Therefore, the blood in his heart belonged to someone else.This is a cruel move. Even if Wu Yijun's blood is not drained, he will die of hemolysis.

The murderer is a formidable opponent with professional knowledge!
In order to verify everyone's speculation, Luo Jin cut off a small piece of Wu Yijun's skin to detect DNA and compared it with the saliva DNA on the cigarette butt. The results were exactly the same, which proved that Wu Yijun's blood had indeed been replaced by the murderer.

Luo Jin carefully examined the body and found a small needle hole in the blood vessel on the back of Wu Yijun's right hand, which should have been left when the murderer injected blood.When Wu Yijun died, the back of his hand was facing down, so there were obvious corpse spots on the back of his hand. If you didn't check carefully, you couldn't see the needle holes.

When a person is lying on his back on the ground after death, normally the back of his hand should be pointing upward. However, when Wu Yijun was lying on the scene, the back of his hand was pointing downward. The murderer knew that corpse spots would form on the lower parts of the body after death, so he deliberately put Wu Yijun's hand on his back. He twisted the back of his hand upwards so that Luo Jin could not see the needle's eye in the short term. He had to admire the murderer's careful thinking.

The murderer probably used a large syringe to inject other people's blood into Wu Yijun's blood vessels, and waited until Wu Yijun's blood was almost empty before injecting other people's blood. Therefore, the murderer must have stayed at the scene for a long time, at least more than an hour. It can be seen that he is a bold and calm person.

Whether it is forensic work or criminal police investigation work, it is impossible to get it right in one step. It takes time to look for clues, and then peel off the cocoons and slowly move toward clarity.Therefore, Luo Jin cannot be blamed for being careless. No forensic doctor can go through life without making small mistakes.Wu Yijun probably hurried to Blue Home after receiving the call from the murderer in Room 204 of Golden Phoenix, and then was killed.According to the analysis of shoe prints, Wu Yijun walked from the door into the third room on the right side of the stairs. When he walked 1.5 meters to the door, the murderer knocked him unconscious with ether, and then poured triazolam into his stomach.Because there was liquid triazolam left in his mouth.

There were messy shoe prints at the scene, indicating that Wu Yijun struggled for more than ten seconds when the murderer covered his mouth with a handkerchief soaked in ether. However, he was not as strong as the murderer, so he soon lost consciousness.

Lu Yingying led the inspection team to pull out all the surveillance videos in the northwest corner of Laishan for review.Reading surveillance video is a very huge project. Because it involves so many areas and the manpower is limited, it may be difficult to get results in a short time.

If the murderer came down from Laishan and then entered the scene, the workload would be even greater, because Laishan is 510 meters above sea level and covers an area of ​​more than 20 square kilometers. It would take thousands of working days or even longer to watch all the surveillance videos. .What's more, they don't know the face of the murderer. Trying to find the murderer from the video is equivalent to finding a needle in a haystack.

Xiaoke and Wu Jiang went to the mobile company and printed out Wu Yijun's call records for six months.The most important thing is the call records on the day he disappeared, especially the call records after he entered the Golden Phoenix Restaurant.They estimated that Wu Yijun was called by the murderer.

On February 2, Wu Yijun answered a total of four calls and made five calls. After he entered Room 10 of the Golden Phoenix Restaurant, the last call he made was to Yang Qian.Wu Jiang felt strange: Why did he leave for no reason?

Wu Jiang and Xiao Ke went to find Yang Qian, one of the shareholders of Junjie Real Estate Company, who was in charge of the Shanda Residential Community in Jiangxi District under construction.This community is not big, with a total of 26 houses, and is located two kilometers south of the Fifth Vocational Technical School.

Wu Jiang called Yang Qian and explained the situation to him. He agreed to meet them. However, he could not leave the construction site because he had to do many things and others could not do it, so he asked Wu Jiang to go to the construction site to find him.

Wu Jiang and Xiao Ke drove the car to the construction site of Shanda Residential Area. Because of the rain, the road was muddy. The car drove past, leaving a long tire mark. People on the roadside were careful to avoid the splashing sewage. Therefore, Xiao Ke Ke drove the car very slowly.

Yang Qian set up a temporary office at the entrance of the construction site. Although it was relatively simple, it was kept clean and tidy.When Yang Qian saw them, he quickly stood up to greet them. After the two parties exchanged greetings, they sat down to drink tea.

"Mr. Yang." Yang Qian is also the vice president of Junjie Company, "We have confirmed that Wu Yijun was murdered, and we are doing our best to track down the murderer."

"Oh, Huo Qingqing has already told me the unfortunate news. Who would be so cruel? If I catch the murderer, I will give him a good beating!" Yang Qian was short and fat, with bright eyes, very charming. God, his muscles are strong and he seems to have endless strength.

"Wu Yijun's last call was to you. What did he say to you at that time?" The water boiled, and Yang Qian poured the boiling water into the teacup, only half of the cup was poured, and then handed it to Wu Jiang and Xiaoke.

"Originally, we made an appointment to have dinner together. Mr. Wu had already booked a room at Golden Phoenix Restaurant. However, he called me at 10:5 in the evening on the 48th and said that he was in an emergency and could not have dinner together and asked me to help with the call. Call other people and cancel the dinner." There was saliva at the corner of his mouth when he spoke, and it often flew out of his mouth inadvertently. This was a bad habit and gave people a sloppy feeling, but he may not have noticed it himself.

"How many people did you invite to dinner in total?"

"There are only four of us shareholders, Mr. Wu and I, and the other two are Mr. Li and Mr. Lin."

"What are the names of Mr. Li and Mr. Lin?"

"Li Sheli and Lin Shuqing. There are four vice presidents in our company."

"Isn't Luo Chengxu among those invited?"

"Mr. Wu invited him, but his little daughter is sick and he has to go home to cook for her. In addition, we are talking about how to raise funds and how to build Shanda Community, so it doesn't matter whether he participates or not. Because the pre-sales of our Shanda community are not ideal, we need to raise funds from the public, and Mr. Luo is not responsible for the financing."

"Wu Yijun has been on the phone with you for almost 4 minutes. Isn't it just these few words?"
