The technical center of the Weiyang Public Security Bureau is not in the compound of the municipal bureau, it is separated from the compound by two streets, and it is alone in a courtyard surrounded by bamboo forests, which is somewhat similar to the villa of Savoy, and is a beautiful and practical modern building.

Speaking of the new technology center, it was built under the strong recommendation of the previous public security chief. In that year, the city government allocated a sum of money for the reconstruction and renovation of the office building of the city bureau.

When the money reached the old director, he pointed to his office and said, "I can live in this house for at least thirty years!" Now is not the era of writing and painting in the office, now is the era of paying attention to science and technology, I don't think this money should build an office building, let's build the best technology center in Qiling, buy the most advanced technical identification equipment, and cultivate the best criminal investigation technical talents! ”

In this way, the Municipal Bureau Technology Center Building was built, plus the purchase of equipment, recruiting talents, after several years of development, Weiyang's criminal technology center has become the province's first, the country's top five public security technology laboratory.

Shen Yu registered in the guard room, and then walked through the bamboo forest to the front of the main building of the technology center.

It is a door with an iris lock installed, which can only be opened by the staff inside.

She sent a WeChat message to La Tiao'er, and after a while, a slender and personable man in a white coat and gold-rimmed glasses appeared behind the glass door and waved his hand at her.

"Student Shen, long time no see!" Spicy opened the door and held out her hand.

Shen Yu shook hands with him briefly, and Spicy Tiao'er smiled briefly.

The original name of Spicy Tiaoer was Xiang Weilong, because the name "Weilong" is the same as the supreme representative brand of Spicy Tiaoer, "Weilong", so when he was in middle school, his classmates called him Spicy Tiaoer. After graduating from high school, he applied for the China Police University, majoring in forensic science and technology, and returned to his hometown after completing graduate school, where he worked in a well-known technology center.

"I also said, this morning I woke up with a clear sky, blue sky and white clouds, I didn't expect that something good was coming, you actually contacted me - can you ask what kind of wind blew you here, won't it just be reminiscing?"

Xiang Weilong also wrote a love letter to Shen Yu when he was in middle school, but she threw it directly into the trash. Later, almost every time they met, he would angrily turn it over and regurgitate.

"Warning you, don't talk about the old days of middle school." Shen Yu took the first step and blocked his mouth.

"Okay," Spicy Tiao'er was a little disappointed, "Then what instructions does Advisor Shen have for coming this time?" ”

"Don't be flamboyant, get down to business. Do you remember that more than 40 days ago, there was an unnamed car accident male corpse, did that person's information be sent to the technical center for comparison? ”

"You mean the nameless corpse on the night of the lunar eclipse, right? I know this very well, I took over - I heard that you were also injured that night? ”

Shen Yu stretched out his arm and kicked his legs: "I've been cured a long time ago - this person's DNA and fingerprint comparison have not been successful, right?" ”

"No, I can't find the corresponding information in the database."

"Did the Y-DNA test work?"

Y-DNA is the paternal genetic detection technology, from this set of genes can trace the information of the same surname of the person being tested, so as to narrow down the scope and lock the identity of the test object.

"Yes, but still no information has been found that can be compared."

"Didn't you find any information in the missing persons database?"

"I have to ask Captain Lin about this estimate, but as far as I know, there is no matching information."

"What a strange man." Shen Yu muttered to himself.

"What? Even classmate Shen found it puzzling? Xiang Yulong teased.

"So you gave up in the end? Lin Ying them? Shen Yu still asked without giving up.

Xiang Yulong shook his head: "If you don't give up, there's no way, criminal investigation, if you can't match, there will be no progress." However, I have already stored and uploaded the information to the whole network, and once I find the information that can be compared, the system will prompt it at any time. ”

"Okay." Shen Yu looked at the spicy strips, "That's bothering you." ”

"No—let's have lunch together, our tech center cafeteria is pretty good." Invited Yu Long.

Shen Yu smiled and shook his head: "Forget it, seeing that you are so thin, you know that the food is average-I have to think about this case again." ”

She said goodbye to Spicy Tiaoer, who sent her to the door. As soon as he opened the glass door, he seemed to remember something again.

"Wait."

"What's the matter?" Shen Yu stopped and looked back at him.

"I remembered that when I first made the genetic test report, although this person's DNA information was not matched, there were some things that were different from the medical genetic level - because it had nothing to do with the case at that time, I didn't mention it to Captain Lin and them."

"Oh? What's going on? ”

"I'll take you to the testing room." Xiang Yulong pointed upstairs and said.

Located on the second floor of the technical center, the laboratory is a large, well-divided cubicle with a large floor-to-ceiling window on the south side of the cubicle, with blinds drawn on the window to keep out the sunlight from the outside.

Xiang Yulong took Shen Yu around the two compartments and several machines to a computer, he quickly entered the password, and then called up a genetic test report.

"You know, now the genetic testing data is very complete, and there is a test called ancestry testing, which is to analyze the ancestral composition of human paternal and maternal lines through autosomal loci, combined with Y chromosomes and mitochondria.

"Although there are many Chinese, most of the people's paternal ancestry actually comes from a number of male ancestors for thousands of years, of course, there are certainly no people of pure-race blood, we are actually the product of thousands of years of national inheritance and national integration.

"But the corpse that was sent on the night of the eclipse - what do you usually call him?"

"'The Man Who Bears the Blame'." Shen Yu said.

"Strange name, strange person really has a strange name - I will follow what you say, this backstabber, his ancestral genes are a little strange. Look—"

Spicy Strip quickly tapped a few buttons again, and then a page of ancestry analysis popped up. Shen Yu leaned over to look at it, only to see that it was written:

"17.33% of the Han people in the north...... Bolgars15.18%...... Mongolian ethnic group: 13.62%...... Sindhi 12.31%...... ukn5.55%……”

After reading it, Shen Yu asked Xiang Yulong, "What does this mean?" ”

"It's the ancestors of this person's genes, such as this person, the genes are more mixed, his ancestors include the northern Han people, the Bolgar people, the Mongolian people, and even the Sindhi people from South Asia, but it doesn't matter, the important thing is this."

Xiang Yulong said and knocked on the three letters "ukn": "ukn, in this system, it is the abbreviation of 'unknon', that is, an unknown ethnic group. ”

"Unidentified race? Is there an unknown ancestor? ”

"yes, that's the problem. Our genetic big data contains the genetic sequence information of all human races, and there will be no 5.55% unknown ethnic group at all! ”

"What do you mean?"

"My classmate Shen, you were so smart when you were in school, why did you become stupid today! To put it mildly, 5.5 percent of this person is either non-human or 5.5 percent of the genes have undergone major mutations! ”https://./15_15456/
