twin detective

This explosive news spread to every corner of the detachment in just a few hours.

There are mixed opinions about this sudden reversal.

Ning Yuan came out of the captain's office and ran to the laboratory non-stop all morning, but the production of pathological slides took time, and no matter how urgent it was, there was no way to rush it.

"Senior Brother, why don't we go to Senior Sister's side to help."

Seeing that he was fidgeting all the time, Fang Yuan tried to make a reasonable suggestion.After all, after the inference that "the deceased was Wen Yang and not Wen Qing" was put forward, the biological samples collected at the two crime scenes had to be re-compared.

"Those machines are only proficient in the use of senior sisters. If we go there, we can only add to the chaos. Let's wait for the results from the pathology side."

Although Ning Yuan was polite, he refused. After all, although they are both in the forensic team, the division of labor between the DNA laboratory and pathology is completely different.

"Oh, alright." Fang Yuan responded weakly, but she didn't sit for a few minutes before moving closer, "At present, the way to tell the difference between the sisters is to build an antibody gene bank It is theoretically feasible to detect and sequence the whole genome, but the cost is too high, so it will not be realistic."

"It's okay, there are machines in the team that can do it." Ning Yuan agreed and didn't say anything more.

There was no way to chat any more this day, so Fang Yuan had no choice but to pretend to be quail in silence.

Ning Yuan stood up and walked out. As soon as he reached the door, he saw his brother walking this way. It seemed that he was looking for someone.

"Aren't you in the interrogation room?" Ning Yuan was a little surprised to see someone at this time.

"The man was brought back, but he insisted on not saying anything. It seems that he can only wait for the news from the DNA laboratory." Speaking of these, Ning Zhi felt a little helpless, but he quickly lifted his spirits, "Although the fruit The original fingerprint information on the knife handle could not be found, but her fingerprint was found on it."

"Well, if there is a serious suspicion, it will not be subject to the 24-hour limit, and the pre-trial team will have more time." Ning Yuan followed up with the conversation, and the two walked forward one after another. When they were almost downstairs, Ning Yuan stopped and didn't continue to walk. At this moment, he was suddenly a little afraid to see Wen... Qing inside what was going on.

It was as if he couldn't think about how Ning Zhi survived the disaster he encountered ten years ago.

"After this case is over, we'll go to the movies." Ning Zhi didn't need to ask, he could roughly tell what he was thinking just from his appearance, so he had to use this easy-to-understand way to trick people.

It's also very strange to say that during the period of investigating the case of the Wen sisters, the two of them seemed to have a magical existence of telepathy, and they could communicate with each other.

Ning Zhi leaned over and beeped softly, and said this, Ning Yuan was amused by him, so he had to say that it is possible to be able to see each other's emotions under the premise of mutual understanding.

"That's right, people are very sensitive in many cases." Ning Zhi hummed, and directly pulled people out.

The only thing that can support their previous inferences, except for the results of the two laboratories they are waiting for, is the rental house of Wen Yang and Liu Xu, after all, that is the scene of the first case.

When passing by the perspective mirror, Ning Yuan still couldn't help but glanced inside, Wen Qing was still sitting stiffly, it seemed that he didn't intend to compromise.

He didn't quite understand what the other party's motivation was for doing this. Maybe he thought there might be a turnaround if he didn't explain?Maybe it was because the police hadn't figured out her identity yet.

But he figured out one thing, and his mood improved a little bit.

"Wen Qing didn't come to identify the corpse that day, probably because she was worried about being recognized by her mother. Maybe the relationship between their sisters is not so bad."

Ning Zhi was carrying the suitcase and preparing to get into the car, he was taken aback when he heard this, and then nodded after a few seconds, "But Wen Yang has prejudice against sister, that's for sure."

He was about to say that there was no trace of Wen Yang found in Wen Qing's rental house, but then he thought of the fact that the DNA of identical twins was difficult to distinguish, so he shut up in time.

That night, he also shared with Lin Zang how the parents distinguished the twins, but now it is a slap in the face.

Ning Yuan's face turned hot, and Ning Zhi thought of it when he heard him muttering, and hurriedly defended him, "After all, there is still a difference between a corpse and a living person, and Mama Wen was informed by us preconceivedly, so it's not surprising to admit my mistake."

The temperament, posture, walking posture of a person standing there, and the timbre when making a sound can only be reflected when they are alive.

Ning Yuan also accepted this explanation, and put forward a new idea, "Wouldn't it be possible to confirm her identity by doing sound wave analysis on Wen Qing's recordings in the interrogation room and the videos she contributed earlier?"

"No." As soon as the words fell to the ground, he denied himself again, "I forgot that there is such a magic weapon as a sound card now."

Ning Zhi listened to him chattering beside him, feeling a bit entangled, but also smiled, "It's okay, even without this, our chain of evidence will be complete."

Then, he raised the question that he had been struggling with for a long time, "It's better to explain the antibody gene pool from afar. With this, can we accurately distinguish the difference between identical twins?"

Although my younger brother had already explained in the morning that antibodies are related to the acquired growth environment, which is the same as personality, but how to change it...he really couldn't think of it.

The person in charge of driving was Fang Ye, who was also going to participate in the second survey. Hearing that they were going to discuss this, he also pricked up his ears.

Hmm... How to popularize these things to the medically blind brother is a very serious problem.

Ning Yuan paused, and decided to give an example that is the easiest to understand, "For example, my brother is allergic to pollen, but I don't have this kind of situation. The laboratory took the test materials of the two of us for typing, and the point of distinction is also here. , this is relatively simple and achievable according to the current technology.”

"You are allergic to pollen. After exposure to the allergen, the body produces antibodies to neutralize the antigen in order to protect itself. This is different from my situation."

"Well, it turns out that's the case." Ning Zhi was stunned, but he understood what it meant. After struggling for a while, he still used his own method as an example, "This kind of relationship with some people is formed in the day after tomorrow. For example, if a person has experienced a bad thing, he will have a corresponding character, but if he has not experienced this bad thing, the corresponding part of his personality may not exist. "

"That's right." Ning Yuan breathed a sigh of relief after finding out that the explanation made sense.

But Fang Ye suddenly lost his mind, turned around and interjected, "So neither the captain nor Forensic Doctor Ning can do bad things. After all, I have now mastered the method to see through the two of you."

Ning Zhi: "..."

Ning Yuan: "..."

After the car fell into silence, Fang Ye giggled a few times, then turned back stiffly.

He should really be thankful that he is now in the driving seat, otherwise, he would really be pulled out and suffer a double fight.

Fang Ye carried the survey box because of his cheap mouth for a while.After getting dressed and entering the scene, he quickly ran into the bathroom.

The entrance is the central scene of the crime, so all the sundries were emptied and taken back for testing, and it was a bit empty when you entered the door.

Part of the bloodstain on the wall has been scraped off, but the mottled bloodstain left in place is deeper, as if it will be embedded in it forever.

Either Wen Qing or Wen Yang was strangled, and Wen Yang was stabbed in the carotid artery to death.

At first they thought it was a fight between Wen Qing and Liu Xu, but now they can only wait for the results from the DNA laboratory.

The person who was strangled might really be Wen Qing, but after the real Wen Yang came up, they had a fierce dispute over this, and there was a time lag between them.

Or the reverse is also possible.

Ning Yuan imagined both of these situations in his mind, and Ning Zhi dragged him straight to the kitchen, where the floor drain used to be. There was a trash can there, but it has been moved away.

The rest of the place is scattered with metal powder, which was left when fingerprints were collected.

"At that time, there was no trace of the third person's life in the trash can." Standing next to the floor drain, Ning Yuan roughly guessed what his brother was going to say.

At the scene of the crime, the trash can is a very precious inspection material.After all, it is full of miscellaneous wastes, and it is these wastes that, after layered processing, can infer the time of the case, the relationship between the victim and the suspect, and so on.

"Yes, I didn't find it, but it's another matter now." Ning Zhi showed him the relevant results, and then simply stated the conclusion, "The toilet paper with saliva on it, the fruit peel, and the paper towel were found in the trash can. Wait, it was detected that most of them belonged to Liuxu and Wen Yang, and the things underneath were compacted, and various physical evidences were layered on top of each other, all of which proved that they had coexisted peacefully for a long time. They are male and female Friendship, to get this kind of result is to be expected."

"But now we can't confirm whether there is Wen Yang in it." Ning Yuan reminded at the right time.

Ning Zhi hummed, and showed him another photo, "This is Wen Qing's kitchen waste and toilet waste, and I didn't find the DNA information of Liu Xu."

"So, catkins appeared in Wen Qing's place, it was just a coincidence." Ning Yuan followed the analysis, and also remembered that the inferences made before are consistent with the present, "the catkins' footprints only appeared in the entrance, living room and balcony, and there was only one way. , and did not return."

Hypothetically, assuming that Wen Qing's appearance in this room was only accidental, then there should be no personal information about her in the trash can, but it could only appear in the entrance.

The two thought of this at the same time, and ran towards that side together.

Bloodstains, hair, footprints, and fingerprints have all been collected before.

So, the most and most likely thing left here now is the exfoliated cells-that is, the dander on the skin.
