This reminds me of a modern joke of "I confirm that I am who I am", and I lost my mind for a moment.

"Didn't you extract the DNA of the deceased before?" Wu Yuhui whispered.

After Wu Yuhui's reminder, Zhang Lihai grinned and patted the back of his head: "That's right!" ”

It has to be said that the rapid development of medical level and science and technology has a great impact on all walks of life, and after the application of DNA technology to forensic science, many murderers have nowhere to hide, which has greatly improved the rate of solving cases.

It only takes a few minutes to collect evidence in vivo, but extracting the data requires specialized equipment, which is only available at district police stations.

It's already the middle of the night, but no one has the intention of resting, Zhang Lihai stayed to continue to interrogate Hong Jingkui, although the suspects can not be tried like in ancient times, what eighty boards at every turn, what rods hit twenty, but now there is also the current method, and later Xiao Wei told me that the most commonly used tactics are fatigue tactics.

The so-called fatigue tactic is to make the prisoners not get a minute of rest, let alone sleep, and then interrogate in groups in turns, and finally most of the prisoners can't stand it and have to confess.

Wu Yuhui and I followed Liu Xili to the main police station.

After waiting for more than ten minutes, Liu Xili walked out with a short breath, his forehead covered with beads of sweat.

"Well, can you confirm that they are brothers?"

Liu Xi glanced at me with strange eyes and muttered, "Brother, something strange happened again...... Let me ...... slowly."

Well? Could it be that they are not brothers! It's not that the brothers look exactly the same...... I wondered unconsciously.

Liu Xili suddenly picked up the two lists again, looked at them carefully, and kept muttering: Impossible, this is impossible!

Wu Yuhui frowned, seemed to be a little impatient, walked up to Liu Xili, and pulled his arm: "Brother Xili, what's wrong?"

Liu Xili's face was pale, he handed the two sheets to Wu Yuhui, and said slowly: "The DNA data of the two people is exactly the same, they ...... They are not brothers, but one person. ”

Alone? That's not! I cursed in my heart.

When Lao Hong died, half of his head was gone, and it was still the crematorium I sent to, so it can't be said that after he was burned to ashes, he regained his human form and came back to life......

The ghost stories of Liaozhai are not so outrageous!

"This is already the second pair!" Liu Xili sighed, "Yesterday I contacted my mentor and told him that the two sisters have exactly the same chromosomes, and my mentor also said that under normal circumstances, it is absolutely impossible to ......."

"Under what circumstances is it possible?" I asked.

"Have you heard of cloning?"

"Heard!"

We both nodded almost at the same time.

"If one person's cells were to clone another person, then theoretically the chromosomes of this ontology and the replica would be the same." He straightened his eyes and added, "Of course, what I'm talking about is only theoretical, because as far as I know, there is no human cloning in the world today, one is that the technology cannot be reached, but the United Nations Council has discussed and banned countries from conducting research in this area." ”

Cloning technology is divided into three stages, the first stage is the cloning of microorganisms, the second stage is the cloning of organisms, and finally the experimental cloning of animals.

The first animal in the world to be cloned by British scientists was a sheep, which was named Dolly, and later dogs, rabbits, cats, etc., were cloned by other countries one after another.

Why is it forbidden to conduct experiments on human cloning? Liu Xili explained that if a person is cloned, what is the relationship between the ontology and the replica? Is it a brother? Is it father and son? It's not appropriate, and what's even more embarrassing is how their wives or husbands get along with this clone......

It will bring a series of troubles and be unethical.

"I contacted my mentor yesterday and he promised to come tomorrow...... This is beyond my knowledge......"

It can be heard that Liu Xili is a little broken at this time.

That night, we rushed back to tell Zhang Lihai the results, and he was so shocked that he couldn't speak for five or six seconds.

Hong Jingkui still didn't say anything, neither wanted water to drink, nor went to the toilet, and always had one expression, he didn't collapse, but I saw Zhang Lihai and they were about to collapse.

It was already one o'clock in the morning, I dealt with the staff dormitory of the police station in the jurisdiction for a night, and the next morning Zhang Lihai told me that Liu Xili's teacher would arrive at nine o'clock, and he wanted to go over and have a look.

When the two of them arrived at the district police station, they saw a group of people walking towards the office building with an old man in their arms, and looked at it from a distance, this old man was a little hunchbacked, how could he be seventy years old.

He is Liu Xili's teacher?

The two of us hurried over and followed us to the reception room on the second floor.

Liu Xili took the old man's hand very respectfully: "Teacher Qi, I haven't seen you for several years!"

The old man smiled and nodded: "I haven't seen a real person, but I've seen you on TV and in newspapers."

The old man looked skinny, but he was in good spirits, spoke loudly, and was full of confidence.

The old man didn't pay attention to others, and after taking out his glasses from his bag and putting them on, he asked straight to the point: "Where is the forensic office?" Take me there! ”

It is estimated that Liu Xili understood his teacher's temper, and he didn't say polite words, so he took the old man's arm and walked out.

A few of us hurriedly followed.

After waiting at the door of the forensic office for more than 20 minutes, the door opened, and the old man was helped out by Liu Xili.

Zhang Lihai asked Liu Xili in a low voice: "What's the matter?"

Liu Xili smiled bitterly and shook his head: "Strange thing! The teacher also said that this should not happen......"

Liu Xili helped his teacher back to the reception room, and the two of them whispered for a while, although the voice was small, but I could hear it clearly.

"Xiaoli! Who are these two? ”

"It should be my own brother, sixty-one years old."

"Their chromosomal data is almost as safe as the same person, theoretically the same person...... You've been before, and one of them is still alive? ”

"That's right! It's a murder suspect, and he was just caught yesterday. ”

"That's good! Can I schedule a medical check-up? ”

"Teacher, you ...... What do you mean......"

"I want to do a detailed live forensic of the man, because even if it is asexual reproduced, there are traces."

After the two communicated, Liu Xili walked to Zhang Lihai's side and told his teacher's thoughts.

"No problem, anytime!" Zhang Lihai replied.

"Now then! You send someone to bring him, and the equipment is only available here......"

When Hong Jingkui was brought, his face was still expressionless, his eyes were dull, and he pushed him away, and he left, walking in a somewhat mechanical posture.

Zhang Lihai and I continued to sit outside the door of the medical examiner's office and wait.

Only then did I notice that Liu Liwei was not there all morning, not only him, but even the forensic doctor Xiao He did not show up.

At this time, I saw the criminal policeman Xiao Wei walking towards the elevator with a brown paper bag, and quickly stopped it.

"Why didn't you see Director Liu?"

Because we are the same age, compared to others, Xiao Wei and I are the most familiar.

"Oh! I went to dig a grave early in the morning! ”
