novice forensic medicine

Chapter 271
Xu Dayuan helped his forehead, seeing Zhang Sannian's sad face, he couldn't say anything else.

Thinking about it, when he was in Qidong, he was in the same state as here. He needed no one, no equipment, but fortunately Liu Yongxin was strong, otherwise he really couldn't do anything.

Glancing at Liu Yongxin, Xu Dayuan said:

"Since there is no missing person in Rudong that matches, let's expand the scope of the comparison to see if there is any relevant DNA information among the missing persons in the province or even the whole country. Is there a rough estimate of the age and height of the deceased?"

Xu Guanhai sighed.

"Xu Bureau told the truth, the identification of the bones is my shortcoming. The dead body was dismembered and put in woven bags, then wrapped in quilts, and the clothes were thrown at the bottom, and then put into baskets.

Director Zhou also saw the bones I put together, and they looked very awkward. I knew there must be many things wrong, but I really couldn't do this.

In addition, there is a bone defect in the injured part of the deceased's face. I judge that the deceased's face was smashed and eaten by rats, so I don't know whether the skull can be restored by your method. "

Xu Dayuan looked at Zhou Ning. He was very confident about the repair ability of the software, but the premise was that there was a big piece missing in the middle of the face with a complete skull. How to fight it?
Zhou Ning glanced at Xiaoqu, who shook his head.

Obviously, he can't do it, and the defect is too large, and the software can't recognize it. This is indeed a design problem.

"It's not in a hurry. I'll invite Teacher Xia to come over later. We'll use the most primitive method to try to repair it. I think the most important thing now is to survey the site.

It is possible that the rats gnawed on the broken face of the deceased, but the bones may not be removed. I watched the live video of the attic. There is only a small ventilation window, which is still a certain height from the ground. The door below is locked, and the broken bones Perhaps scattered in the corner of the attic. "

Xu Dayuan nodded, and looked at the photo that the criminal police found. Sure enough, the window was about 20 centimeters above the ground, and it was not difficult for the mouse to go up.

Zhou Ning paused, and asked with a puzzled look:

"I have a question. According to the photos at the scene, the dead body was dismembered and hidden in the attic. It was completely bone-shattered, and even the clothes were partially decomposed. To this extent, it seems that it has been at least seven or eight years.

Moreover, if the wrapping is so tight, the rate of decay of the corpse will also be slowed down, but the smell of the decay of the corpse is particularly pungent, and it will not disperse for a long time. Is there no one around to react? "

Xu Guanhai nodded repeatedly, found a picture and enlarged it, pointed to the big screen and said:
"To tell you the truth, I also asked this question at the scene. Director Zhou, look, this is the location of Xu's family. They are in the southeast corner of Renjiazhuang Village. Not far from his house is a pig farm.

After the visit, I found that the people around me have indeed reported that the location in the south of the village is particularly smelly. It has gotten better in the past two years. In the past few summers, I couldn’t open the windows at home. At first I thought it was a stinky ditch in the pig farm. The village spent money to re-dig it. ditch, but the smell is still there, and it has not been treated since then.

The pig farm was built with funds raised by the village, and it sends money to every household in the village every year. If you want to complain, you will cut off your own financial resources, so even if it stinks, everyone will bear it. I have also paid attention to hygiene for several years, so no one has considered this aspect. "

It's no wonder that Zhou Ning suddenly realized, but although the smell of corpses is getting weaker every year, but living in this far away Xu family, can't you feel it, after all, this is the source!
But turn around and think about it, according to the satellite image just now, the north house is still divided into two parts from the front yard. Zhang Sannian also introduced it just now. It turns out that the backyard is lived by old people. After he passed away, he wanted to tidy up .

It seems that the old man who originally lived here was a very stubborn and stubborn person.

Xu Dayuan glanced at the time, it was approaching five o'clock, and looked at the location of Renjiazhuang Village, he waved his hand and said:

"Three years, let's sort out the report on the 5.11 drowning case first. As for the second investigation of the 2.28 bone case, we will go there early tomorrow morning. Has it been closed?"

Zhang Sannian nodded.

"The Xu family was terrified when they found these bones. The blood pressure of the old Xu's daughter-in-law was 220. Now she is hospitalized in Rudong People's Hospital. Old Xu is taking care of his wife. Fortunately, the house is locked. Our people, Just stay at the village committee and watch the scene."

Zhou Ning stood up.

"Xu Bureau Zhang Da, I want to look at the skeleton first, one is to see if it can be put together again, give some information about the deceased, and the other is to study the skull of the deceased."

Xu Dayuan knew that Zhou Ning didn't want to delay the working group's time, and the next step of the investigation could only be carried out after obtaining the relevant characteristics.

After all, the autopsy on the skeleton takes longer, just like the Xiaolongshan archaeological mutilation case. Fortunately, the skull is complete, and this difficulty is more than a little higher than that.

"Okay, arrange it in three years, and send some food to Zhou Ning and the others later, don't disturb them."

Zhang Niannian was a little embarrassed, so he nodded quickly.

"Don't worry, I'll have someone make it for Director Zhou and the others alone in a while, to ensure that it's nutritious and delicious."

Da Zhao bared his teeth and smiled.

"It's been a day, and this is my favorite sentence."

Xu Dayuan waved his hand.

"Okay, you go and do your work first. Let's stay here and talk about the findings at the scene and the situation of the Xu family in detail. Xiaoqu, you can go with Director Zhou and the others."

After receiving the amnesty order, Xiao Qu hugged the computer and hurriedly followed Zhou Ning and the others.

Several people came to the next door to the dissecting room, which was very empty. There was a large table in the middle, on which all the bones were placed. Zhou Ning took a look and found that Xu Guanhai had already numbered each bone. He is strong.

The light in the room was turned on, but the brightness was not very high. Sun Gaotie trotted out and came back holding Zhou Ning's special LED light magnifying glass after a while.

Zhou Ning almost laughed out loud, this guy knows himself quite well.

"Okay, Xiao Sun participated in the 2.21 Xiaolongshan archaeological mutilation case. Think about how I sorted it back then. You remember, you and Zhu Xingxing put all the bones back together now, and the speed is a bit faster."

After finishing speaking, Zhou Ning dragged the LED light to look at the skull, and ignored the two people. Da Zhao and Xuetong Yang kept taking pictures. After all, there was a serial number on it, which saved a lot of effort.

Xu Guanhai was a little dazed, but it seemed that Xiaolongshan's name was familiar to him, and he didn't know where he had heard it before, so he hurriedly dragged Liu Yongxin, and went to the side to ask carefully.

After listening to Liu Yongxin's introduction, Xu Guanhai looked admiringly, and looked at Zhou Ning, not envious of Liu Yongxin having such a good apprentice, but shocked by his ability.

After holding back for a long time, Xu Guanhai leaned into Liu Yongxin's ear and said:

"I said you really took advantage of it. I learned this ability from Li Chengbin. Don't talk about your apprentice in the future!"

Liu Yongxin missed his teeth and patted Xu Guanhai's arm.

"Come on, my apprentice became Li Chengbin's doctoral student in September last year. When this case was solved, he just went to the city bureau. He was cleaning Cui Haibin's ass, you know. My apprentice's ability of self-study is beyond the average person. Don't say grapes are sour if you can't eat grapes."

Xu Guanhai shut up and became even more depressed.

The two didn't chat anymore, but leaned next to Zhou Ning and watched him observe the skeleton, but soon Xu Guanhai was attracted by the actions of Sun Gaotie and Zhu Xingxing.

These two people, like playing a jigsaw puzzle, kept moving the position of the broken bone. After 10 minutes, the two of them checked it again and raised their hands towards Zhou Ning.

"Boss, we finished the fight, but there is a missing piece of the left femur, a piece of irregular triangular broken bone with a size of 3*2 cm."

Xu Guanhai jumped up and rushed towards the packing box next to him, Liu Yongxin was taken aback.

"Old Xu, what are you doing, are you scaring me to death?"

Xu Guanhai didn't say a word, he rummaged around, and quickly walked over holding a small bag.

"The defect is here. I found this when I went to the attic. I think it should be part of the skeleton, but when I put it together, I forgot this."

Zhu Xingxing took it, placed the fragment on the damaged part and clapped his hands.

"Perfect, but it's a pity that no bone fragments missing from the deceased's face were found."

Zhou Ning put down his skull at this time, glanced at it, and nodded towards the two.

"It's okay, speed up next time. Zhu Xingxing's movements are too slow. Go back and observe the characteristics of the tibia carefully. It was Sun Gaotie who discovered your mistake just now."

Zhu Xingxing blushed, embarrassed, but nodded vigorously.

"Don't worry, boss, I'll focus on this practice as soon as I get back."

Xu Guanhai slammed his mouth, he felt a little uncomfortable, he was an intern, a newly assigned forensic doctor, and his proficiency in bones was not a little higher than his own.

Hey!
Zhou Ning walked around the skeleton, asked Sun Gaotie to measure it continuously, and asked Yang Xuetong to take pictures. He even picked up the pubic symphysis and glanced at it. Finally, Zhou Ning returned to the position of the skull of the deceased, picked up the skull and looked at it again.

"The deceased was male, aged between 18 and 20, with a height between 176 and 178 cm, and a thin build. According to Xu's forensic doctor's weighing, I estimated that the deceased's weight was 120 to 130 catties. The fatal injury was in the neck, and the murder weapon was an axe. , but the strength of the murderer is not great.

There were three cuts in the neck, two cuts left scratches on the third and fourth cervical vertebrae, and only one cut into the space between the third and fourth cervical vertebrae. Look at the edge of the fourth cervical vertebrae. The defect is just that the ax got stuck, and the murderer shook it many times and broke it.

The murderer was not good at using an axe, and he did not know how to find the articular surface to cut the body, and the tools were not good enough, so the limbs of the deceased were cut off, but the torso was not cut.

As for the facial injury of the deceased, I think it was caused by the blow from the other side of the axe. It can be seen that these two places are square, and there is a bone inlaid on the brow bone. The murderer should know the deceased and an acquaintance who committed the crime, so it must be destroyed. face. "

Zhou Ning spoke very slowly, and Zhu Xingxing kept recording beside him. After he finished speaking, Zhu Xingxing also finished recording.

"Boss, why was the deceased hidden in Xu's house?"
