twin detective

The cake was sweet and the taste seemed to take a long time to dissipate in the mouth.

The two of them ate and played for about a third of the time, except for a piece reserved for Aunt Li, the rest was distributed to colleagues upstairs and downstairs.

At this time, Ning Zhi showed bad intentions again, and what he assigned to Lin Zang was the word "wave", so when he arrived at the detachment the next day, Deputy Lin was still complaining about his bad behavior to everyone.

"Is it the cake that tastes bad or the writing that doesn't look good?"

Lin Zang was full of complaints, turned around abruptly, and saw Ning Zhi standing behind him, with a half-smile expression on his face, as if he wanted to beat him up.

This is a sending proposition...

So Deputy Team Lin laughed a few times, and hid behind Ning Yuan, "Ning Yuan, what's your word?"

"It's Yong." Ning Yuan let him hide, but Lin Zang trot behind him worriedly, and asked, "Where's your brother's?"

"It's manga."

Yong, Lang, Man?

What the hell is this pieced together?

Lin Zang didn't get the answer he wanted, and ran away before being beaten.

On the third floor, the first room on the right is the captain's office, and the forensic team is the second room from the left.

Therefore, as soon as the two came up from the stairs in the middle, they saw the forensic lady from the DNA laboratory waiting.

She was holding a pile of bills in her hand, and was looking this way, seeing that Ning Zhi was about to open the door, she stepped aside a bit.

At this time, the DNA results from the scene of the Wen Qing case should have come out. Ning Yuan wanted to take a look, but before he could ask, Ning Zhi opened the door and motioned him to go in, "Let's go together."

"Since the younger brother is here, it's easy to talk about. Please help explain to the captain. I have other things to look at, so I will go to work first."

The forensic doctor lady didn't follow in, and when Ning Yuan was stunned, she stuffed the list in her hand.Ning Yuan came back to his senses and found that she had gone far away, and even the sound of her footsteps was obviously urgent.

"Recently, the two cases have been pressed together, and there are really too many inspection materials to look at." Ning Yuan also helped explain when closing the door, "We celebrated our birthday yesterday, and the senior sister didn't have time to have a simple meal together."

"Well, it's okay, let's see for ourselves." Ning Zhi smiled when he saw that he was cautious, "I feel much better after my birthday, and you don't have to worry about these little things affecting your mood."

As he spoke, he pulled out the chair again and motioned for him to sit first.

Ning Yuan sat down and didn't look at the materials immediately, but took out a big white rabbit and handed it over.Of course, it's not how strict Ning Zhi treats them on weekdays... It's that when encountering extreme depression, people will really explode if they are not careful, not to mention that apart from the Wen family sisters, his brother has other things special circumstances.

"Let's read the materials first. I really don't understand some technical terms. You can just talk about the results later."

Ning Zhi ate the candy obediently, and turned his head to look at the whiteboard beside him. The mind map on it had been messed up. He didn't know what new changes the new test results would bring to it.

At the beginning of the autopsy, the forensic doctor will record the relevant information of the corpse, such as fingerprints, palm prints, and footprints.

And when it comes to the formal autopsy, when it comes to poison detection and the need to use DNA technology to confirm the identity of the deceased, heart blood will be taken as a sample for inspection.

Ning Yuan's guess was correct, the laboratory issued exactly this kind of report, but it was not Wen Qing's case, but Liu Xu's case.

For this report, he glanced at the results page first, and couldn't believe his eyes.

According to the results, the biological samples collected from Wen Qing's rental house passed the same certification as Wen Qing's blood, and also included the DNA information on Liu Xu's palm and forearm, all of which belonged to the same person. That is Wen Qing.

Ning Yuan couldn't hide his surprise the moment he read it out, and even his voice changed.

"Wait a minute, toothbrushes and towels are commonly used by Wen Qing, and the materials extracted from them must be her biological samples. And we speculate that Liu Xu and Wen Qing may have fought, such as choking their necks, etc., then this It is not surprising that the three test materials belong to the same person."

Ning Zhi rebutted subconsciously, but always felt that something was wrong.

"There is a paradox in the time of death." Ning Yuan reminded one after another, "The key is that in Wenqing's rental house, we did not find any traces of the third person's existence, including in the trash can, nor did we find any information. Then it can only be proved that there was no third person in this room before the incident or even a day before."

"According to the results of the autopsy, Wen Qing died earlier than Liu Xu, about half a day later."

"Then do you think Wen Qing killed Liu Xu to vent his anger after his death?"

"Impossible." Although Ning Yuan said these words extremely calmly, Ning Zhi was startled, almost jumped up, and then subconsciously looked at the beads on his brother's wrist. Except for this special case, he had not seen other similar incidents.

"Therefore, there must be something strange about this case. The one who killed Liu Xu must be someone else." Ning Yuan made a conclusion and went to touch the candy to eat, and the serious atmosphere was ruined in one fell swoop.

He had just stuffed the candy into his mouth, but now Ning Zhi became serious, "If we analyze the biological samples of the identical twins, we can distinguish the fake from the real."

"But with fingerprints, everyone is unique."

As he spoke, he hurried to the computer again. After the screen lit up, he quickly found all the on-site investigation records of the Liu Xu case in his exclusive folder.

"Yes, identical twins are two embryos split from one fertilized egg, so apart from the special case of gene mutation, even the DNA inside the nucleus is the same."

The atmosphere suddenly turned into a criminal investigation drama, Ning Zhi listened, paused while searching for the fingerprint screenshot, and looked towards Ning Yuan with a stiff neck.

He and Ning Yuan are really close, but this feeling of "you are me, and I am you" is still a bit intrusive.

His sudden expression is still very cute. Ning Yuan was amused by him, and he explained after laughing, "It's not what you think. If this is the case, wouldn't the twins be able to hide the truth when they commit crimes. People are growing up." During the process, different antibodies will always be formed due to different experiences, and if we find the differences in the antibody gene pool, we can accurately distinguish their identities."

Oh, it's much more comfortable if you think about it this way.

Ning Zhi pursed her lips, and went back to continue looking for pictures.Although he didn't know how long it would take to do this kind of test, it would take several hours for the DNA laboratory to do the same certification with nine genetic points.In this case, it must take longer.In contrast, comparing fingerprints is faster.

Wen Qing died earlier than Liu Xu, and there is no doubt that Wen Yang was the only person whose DNA information was roughly the same as hers.

So maybe the sharp wound on Liu Xu's body was the result of Wen Yang knowing that his sister was killed?

That fruit knife, Liu Xu first cut Wen Qing's neck, and then Wen Yang took it away from the scene and used it as a revenge tool to stab the murderer in the chest?

So... what about her alibi?

Moreover, whether Liu Xu is the murderer who killed Wen Qing is still to be discussed... Although from the current point of view, he is indeed the most suspected.

There are motives for the thesis fraud to be discovered.

It is possible to kill the wrong person because of a moment of anger.

There is also the act of purchasing activated charcoal around the time of death.

The most important thing is... Except for the landlord, only he has the key to the basement and can complete the act of removing the corpse.

It's a pity that... if calculated in this way, the fruit knife has been touched by so many people, and the possibility of finding the original fingerprint...is not too great.

Ning Yuan is still making calculations, and Ning Zhi has already come up with the result. His voice has a questioning tone, "Is the fingerprint collected in Wen Qing's rental house the same as the fingerprint collected on the corpse? superior."

The fingerprints collected at the place where Wen Qing lives are different from her own?

If the DNA information doesn't match, you can push the blame to another person... What about fingerprints?

Ning Yuan was taken aback by this sudden change, and forgot that he couldn't actually understand the comparison chart of fingerprints, and ran over.

At this time, Ning Zhi was already calling Xu Yang and the others, the phone had already been dialed out and rang, Ning Yuan quickly stretched out his hand and hung up.

"The results of the pathological slides have not come out yet, so just wait."

The person who died was not Wen Qing but Wen Yang.

The result of this fingerprint overturned all the previous inferences, but some paradoxes seem to be connected.

Ning Yuan felt a little confused, and wanted to run to the laboratory, but also thought that the slices might not be done yet.

When Ning Zhi was hung up, he became more rational. He took the fingerprints collected from the body and the fingerprints collected in Wen Yang's rental house to compare. This investigation further confirmed the guess just now.

"These fingerprints come from Wen Yang and Liu Xu's rental house. We have collected a lot of them, and we can confirm that they belong to Wen Yang himself."

"So the person who had the accident was indeed Wen Yang, so the current Wen Yang...is his sister Wen Qing?"

This is simply cheating and deceiving... No matter what idiom is used, it is not enough to describe his shock.Ning Yuan could not wait to see the results of the slices immediately. After all, only by observing the dissolution of the cardiomyocyte nuclei can he make the most accurate judgment on the time of death.

After a short period of panic, Ning Zhi had already thought about his next move, "Ask her to press her fingerprints."

After the biggest point is overturned, it seems that the previous paradox has a direction of explanation.

And after tearing such a hole, you can find that there seems to be doubts everywhere in the performance of "Wen Yang".

For example, the steps of the study room.

The lipstick in the surveillance video.

When I went to see the scene of the "Wen Qing" case for the first time, the landlord opened the door lock.

She said she had lost the key to the basement...not at all.

She said that she and her classmates were doing a final project, but when the other party called Wen Yang's name, she didn't respond.

For another example, she subconsciously reversed the whereabouts of the two sweaters of the same style, and finally couldn't tell when she posted what.

What is even more revealing is her inconsistent attitude.

It was cold at first, and then madness. If you think about it, she herself felt torn in this transition.

The details of these days came slowly, Ning Yuan thought a lot and felt that his mind was in a mess, but he still remembered a very important point, "Her classmate may have perjured himself."
