Zhou Ning shook his head, he couldn't figure this out.

According to the information provided by Zhang Sansan, the two children of the Xu family, if they were calculated according to the eucalyptus seven years ago, it was 2005.

The eldest son, Xu Qing, was 25 years old at the time, and he was already working in Rudong No. 1 Middle School, although he did not buy a house, he lived in the dormitory and was not at home all the year round.

The second daughter, Xu Dan, is 21 years old, studying at Ludong Provincial University of Finance and Economics, a junior student, the school is in the provincial capital, and she returns home once in half a semester.

And the old Xu Xu Xiangnian is a doctor in the village clinic, who has been working hard for more than 30 years, and Xu's mother Zhang Shan is a middle school teacher with a good reputation.

Zhou Ning couldn't figure it out, and he couldn't give Zhu Xingxing an answer.

"There's no point in speculating at this point, let's do an autopsy of the bones first."

Zhu Xingxing shut up, Sun Gaotie was conscious, and registered all the bones, Zhao Xinli and Yang Xuetong kept taking pictures, and Zhou Ning dragged the magnifying glass of the LED light and kept carefully observing up and down.

After studying the bones, he walked over to the table next to him and began to examine the clothes that had rotted into pieces.

This dress looks like a suit, Zhou Ning directly looked for the position of the neckline lining of the suit, and only found that the trademark on the inside of the neckline had fallen off, Xu Guanhai came over and used tweezers in the pocket to find the sign.

"Director Zhou, are you looking for this thing, I found it in the bag and stuffed it in my pocket."

Zhou Ning observed that the sign should have been a silver backing, embroidered with a black logo, which looked like a horse, with a flying mane, and a line of letters YOUNGOR below, without a Chinese logo.

"Youngor?"

"Well, it feels like Youngor, but this brand doesn't seem to be so famous in the past two years."

Xu Guanhai kept nodding.

Zhou Ning pinched the material and rubbed it slightly, the material was very dense, it seemed to be dark gray, and there was a grain feeling inside.

"When you sent it for inspection, did you check the material of the fabric of the clothes?"

"I checked, it is said that it is 90% wool, and the material is a relatively good wool material, but now the suit material is rarely used like this, and I feel that this material is not cheap."

Zhou Ning snorted and stood a little farther away, although the clothes were seriously torn and defective in many places, but it was indeed as Xu Guanhai said, this suit was not cheap.

"Lao Yang measured the waist circumference of the pants, as well as the length of the pants, the width of the shoulders, the length of the sleeves, the size of the collar of the shirt, and the size of the shoes, let's compare it, and whether there is a discrepancy with the weight of the deceased estimated before, be careful not to tear it, the material has been soaked in blood for many years, and it is already bad."

Yang Xuetong hurried to measure, Xu Guanhai stepped forward to help, and the two finished the measurement in a short time.

And Zhou Ning also checked the location of the torn clothes and pants, which completely coincided with the location of the cut on the bones of the deceased, which means that the deceased was attacked when he was fully clothed.

The deceased, according to the previous analysis, was 18-20 years old, 176-178 cm tall, slightly lower in weight, and thinner, but the explosiveness and reaction speed were the strongest at this age, and the deceased's phalanges, ulna, radius, and humerus did not resist injuries.

It shouldn't be!

Zhou Ning closed his eyes slightly, and the black image of the murderer and the deceased appeared in front of him, according to the position of the slash on the deceased's body, like a small animation, and moved suddenly.

The deceased was slashed three times in the neck, neither of which was fatal, he could dodge, he could resist, he could react, but there was none, it was like lying there honestly, waiting for the murderer to cut him.

Moreover, the most important point is that the murderer's strength is not great, there are many marks of blows on the fractured surface of the tibia and fibula, even more so on the ankle face, and as for the arm, it was only cut from the position of the shoulder joint.

Zhou Ning opened his eyes and turned his head to look at Xu Guanhai on his side, such a sudden action, Xu Guanhai was startled and caught the reading glasses that fell.

"What's wrong, Director Zhou?"

"Forensic Doctor Xu, when you sent it for testing, you sent pieces of clothing, right, since you can extract DNA, did you do a poison test?"

Xu Guanhai shook his head.

"The DNA laboratory department of the Municipal Bureau also tossed three or four times before extracting it."

Zhou Ning nodded slightly, Yang Xuetong came over at this time, handed Zhou Ning the measured results, glanced at the data, and Zhou Ning narrowed his eyes slightly.

"It seems that the deceased's weight is a little higher than I calculated, and he belongs to a very lean type, weighing between 130 and 140 pounds."

Zhou Ning paused, took out his mobile phone, and dialed Cui Lili's number.

"Director Zhou, do you have another work arrangement?"

Zhou Ning was a little embarrassed, after all, it was already ten o'clock at this point, and it stands to reason that he had already gotten off work.

"Sister Cui, I have something to ask you, on February 29, Rudong City sent a blood-stained cloth for testing, and DNA needs to be extracted, and Forensic Doctor Xu said that you did it three or four times before extracting DNA, I want to ask, can these old blood stains be tested for poison reaction?"

There was a sound of computer keyboard tapping on the other side of the phone, and Cui Lili seemed to be looking for a record, and only after a while did she say:

"I found it, the sample sent for testing is a 5*5 cm cloth, and the blood sample that can be collected is too small, if the amount is large, you can try to conduct poison analysis, but do you have a direction? If you have a direction, this speed can be a little faster! ”

"Poison drugs that can quickly and quickly lose consciousness in a short period of time are easy to buy and easily available in society."

"You're too big!"

Zhou Ning smiled, in fact, he thought of a few, but it was easy to affect the direction of the inspection.

"Sister Cui, I'll ask you to send more blood-stained fabric over in a while, and please arrange someone to work overtime to do it."

"Okay."

Hanging up the phone, Zhou Ning looked at the pieces of clothes on the table.

"Da Zhao put up the two trouser legs and asked the Xu Bureau to send someone to quickly send the things to the laboratory department of the technical department, which is faster."

Da Zhao hurriedly loaded his things, and marked the relevant content on the bag as he walked, Xu Guanhai was a little excited.

"The clothes have been torn like this, and it looks like the years are not short, so can you still extract the poison inside?"

Zhou Ning nodded.

"A new batch of equipment from the laboratory department, but the premise is that there needs to be enough sample size, try a few more times, and maybe you can find trace residues, which depends on luck."

Several people were silent, it is true, the deceased has been ossified, all that can be left is this little blood stain on the clothes, and all the relics have no information about the deceased at all, the identity of the deceased cannot be found, and everything else is in vain.

Zhou Ning returned to the platform of the deceased's bones, leaned down slightly, and faced the mutilated skull, which was extremely seriously injured.

Starting from the position of the left eye socket, to the left jaw is mutilated, and the teeth are not complete, Zhou Ning turned his skull to observe it carefully, and looked up to look for Xiaoqu's figure, but after looking around, he didn't see anyone.

"Where's Xiaoqu?"

Sun Tie pointed out the door.

"Teacher Qu has been calling outside and hasn't come in, shall I call it?"

Zhou Ning didn't say anything, he walked out of the door, Xiaoqu saw Zhou Ning hang up the phone in a hurry, and hurriedly walked to Zhou Ning's side.

"Looking for me?"

Zhou Ning nodded.

"The deceased's skull is incomplete, can the software analyze the rest of him?"

Xiaoqu shook her head.

"I just talked to Dr. Lu about this problem, the previous software analysis and scanning, the premise is that the integrity of the skull should be about 90%, so that the search of the mold lake can be carried out, the collection points are not enough, and the results of the restoration are not ideal, so I gave up this part of the mold lake search.

I discussed with Dr. Lu that tomorrow we will adjust the software and try to restore some of the functions and the function of the model lake search, but this will take time, not a day or two to complete. ”

Zhou Ning nodded, he understood Xiaoqu, Xiaoqu They are scientific researchers, and they want to use data and test results to speak in everything, but Zhou Ning's job is not an experiment, he needs to extract his own usefulness from the information left behind.

"Got it, I'll call Teacher Xia."

Zhou Ning walked to the corner of the corridor and dialed Xia Momo's mobile phone, when the ring was about to end, Xia Momo connected the phone, and there was a slight wheezing sound on the other end of the phone, Zhou Ning was stunned.

"Hey, Mr. Xia?"

"What's wrong, Director Zhou?"

"If you're inconvenient...... I'll call you later. ”

"Tell me, I'm moving things, I've put them down now."

Zhou Ning reacted, in Huining Province, where Xia Momo was temporarily asked to go before, she was not there when the Xia family moved, maybe she went back to pack her things and move to a new home.

Thinking of this, Zhou Ning didn't bother anymore, and hurriedly said:

"That's right, the two students you brought, can you let Dr. Lu arrange for someone else to bring them first, I have a deceased man's skull here, the defect is very serious, the left side of the face, basically a missing state, and the broken bones can't be found, I want to use the previous method to restore it manually, if I can I let someone go over to pick you up."

Xia Momo thought about it.

"Let someone come to the community here at Qinda to pick me up in half an hour, I need to prepare some things, and I have to go to the laboratory, after all, there are no materials at home, is the skull you said a replica or a real skull."

Zhou Ning patted his head, and then he thought of this.

"There are only real skulls, I haven't found a place here that can do 3D printing, the laboratory of Qin University can make it, I will let Xiaoqu collect data later and send it to you."

Xia Momo smiled.

"I see that you have been affected by Xu Ju, and your temperament has become so anxious, okay, don't let people come to pick me up first, let Xiaoqu send the data later, I'll find someone to go over and prepare, and then print, it is estimated that it will take some time, and I will go over immediately after I finish it."

After all, 3D printing technology is now in the experimental stage, and the data must be very accurate, otherwise it will be easy to make mistakes.

Before, Zhou Ning used an inverted mold to replicate the skull, but this deceased is not suitable for this method, after all, the deceased's skull is now very fragile, and it can fall apart at any time if touched with a little force.
