twin detective

For the next few days, including weekends, Ning Yuan was in the laboratory helping with the DNA testing of the pile of hair.

There are 22 hairs collected from the site, of which [-] hair follicles are available for testing.Each of these samples needs to test eighteen loci. When all the tests are completed, it will already be Tuesday of the next week.

"According to the report, there are [-] owners of these [-] hairs, including seven males and eight females. According to the limited location of collection, I guess that most of them come from kindergarten staff and students from six classes. And the parents responsible for picking up and dropping off. As for whether there is the suspect among them, the probability is really hard to estimate."

When Ning Yuan took the things to his brother's office, he found that Lin Zang was also there, so he simply shared the test results with them.

"Oh, I see."

"Oh."

Ning Zhi and Lin Zang Qiqi nodded to indicate that they had already heard it, but when it came to medical knowledge, they both only knew some superficial knowledge because of their professional relationship.If you need information on weekdays, you just read the comments next to the report or simply ask the forensic doctor to ask.Let them hold the report by themselves and read it for a long time, but they can only see their eyes darkened, and they can't see why.

But if you want to confirm the identity of the owner of the hair, you must get two samples, and one of them has been confirmed for comparison.On this point, they are still clear.

"In the existing official database, there are only DNA information of criminals, missing persons and their parents, which is not of much reference significance for the current large-scale search." Ning Zhi frowned, and directly looked away from the report up.

"Yes, although the relevant databases have been done very well, there is still a serious shortage of samples for the more than one billion people in the country." Lin Zang sighed, "If it happens to exist, it will be a pie in the sky. thing."

"As I said before, there may not be the suspect's hair in it. As for collecting samples from other people for comparison, it is also a huge project." Ning Yuan reminded them, and added, "Getting different samples That's the sure clue, I thought Vice-Captain Lin was used to this feeling."

"Even the little angel from far away made fun of me, and people's hearts are darkened." Lin Zang was so angry that he beat his chest and stamped his feet.

Compared with Ning Zhiyi, he can really be described as "lively and cheerful", and he is more able to mingle with his colleagues.So more often, colleagues call him by his name when they meet. As for the word "deputy team", Lin Zang feels that he has not heard it for a long time.

Now being called out like this, he could only feel shivering.

"Brother is in charge and I went to the laboratory to search in the two databases. Deputy Lin is so eloquent, so let's work hard and go to the kindergarten to collect hair." Ning Yuan was unmoved by this childish ridicule, and continued. Added a cool breeze to him.

Lin Zang only felt the chill on the top of his head. He couldn't bear it anymore, so he endured it.

There is only one rule of survival in the detachment, no matter what happens, don't offend forensic doctor Ning.He himself didn't make any threats, but he had a brother who protected the calf. He took revenge by putting chopped coriander in the lunch box, taking away the powder packets in the instant noodles, and "unintentionally" walking away from people on the desk many times. Inkpad.Including but not limited to these types, people can have new tricks every time they toss, and the innovation ability is great.

Lin Zang had been tossed about a few times before, and now his desire to survive is getting stronger and stronger, so now he can only touch the top of his head and rub the cool breeze, and then show a smirk, "With the cooperation of the kindergarten, it is naturally not a problem to get the specific list The key is how to collect DNA after getting it? Will doing it on such a large scale cause panic? We have encountered this kind of thing before, and in general, it has to be carried out in a relatively closed environment. The case is also quite special , if there is a homicide case, it needs to be compared with the family’s DNA big data based on the Y chromosome.”

"Why don't you bother your colleagues on the household registration side and tell the public to do a census?" Ning Yuan helped to make an idea, but immediately denied himself, "No, the current census of our province does not collect DNA information, and it is not yet available. The number of years, the excuse is too clumsy."

"And if the suspect is among them, doing so may also scare the snake away." Ning Zhi shook his head.

"But it is also possible to force him out and walk into our field of vision. Therefore, I would like to trouble Captain Ning to compare the database first. It is best to find the relevant information in the database, so as to spare my life." Lin Zang Talking loudly, he was finally dismissed by a big white rabbit in Ningyuan.

When he went out, there was a little black cloud over his head, and it was still dripping rain.Ning Yuan was amused by his own imagination, left a piece of candy for his stingy brother, and took out the thermometer.

"It's all right, there was no repetition last night, and there was no scar left." Ning Zhi's tense face immediately cracked, and he made a gesture of surrender.

Lin Zang embarked on the important task of collecting hair without hesitation. Fortunately, the head of the garden also cooperated as he said, and immediately provided a list of everyone.

Seeing that Lin Zang kept flipping through the roster, the principal knew that he still had no idea about finding the child, so he hurriedly moved a few steps closer to express his doubts.

"Well, I hope to find it soon." Lin Zang continued to turn a few pages, while still looking for a suitable reason for himself.

"It's a good thing that the child's disappearance was not leaked, otherwise it would only cause greater panic." The principal answered the words and looked at the monitor worriedly.It seems that Mengmeng will suddenly appear in the screen after a few more glances.

Seeing her like this, Lin Zang also became nervous, and then remembered the information leak, and quickly asked, "I remember that you called all the parents of the children on the night of the incident, how did you solve this matter later? What is the attitude of the parents now?"

Only then did the headmaster look away from the monitor, "Afterwards, I sent a message to the parents, telling them that the child was accidentally locked in an indoor activity room, and now he has been found. The children in the same class I also asked, and told them that my little friend transferred to another school and went to another city with my parents."

It would be great if this is the case, Lin Zang sounds a little uncomfortable.After a few pleasantries, I went to the big class to collect data.

There are ready-made cotton swabs in the medical management room, which is very convenient for collecting cells in the mouth.

On weekdays, it is the DNA laboratory that is responsible for storing all kinds of biological information collected, including the database about criminals and the DNA anti-trafficking database.

In the previous database, fifteen samples were compared one by one, and no information was obtained.

Ning Yuan rubbed his eyes and continued to stare at the screen.At this time, the screen has already entered the anti-trafficking database.In this database, there are DNA samples of parents who reported the loss of their children, as well as DNA information of minors who wandered and begged on the streets. Usually, every time a new child is found, it will be entered into the system for blind comparison. Match cases of successful family reunions.

At this time, the two of them just had the mentality of giving it a try. After all, they had failed once before. However, when the samples were put into the warehouse one by one, the system started to operate, and the vast amount of DNA information was automatically searched and compared. Page, still feeling nervous.

After an unknown amount of time, suddenly, a piece of overlapping information automatically popped up and appeared on the screen.

According to the search results, the last sample came from a middle school student who disappeared seven years ago. Her DNA information came from the toothbrush she used before she disappeared, and the DNA information of her parents came from the collected blood samples.

Ning Yuan stared at it for a few seconds and checked repeatedly, only to be sure that he was not hallucinating because of excitement.

The author has something to say: no... why is Ning Zhi so naive.Decided to give Ning Zhi an alias: Ning · Brother-guarding Mad Demon · Childish Ghost · Zhi.
