Qiao Zhen put on rubber gloves, looked around, and then squatted down and quietly plugged in the power of the instrument. Shi Yan followed behind her, and the two of them stood side by side at the entrance of the bedroom, the quilt on the bed was messy, and it seemed to carry the residual warmth of the owner.

As far as the eye could see, there were no obvious blood stains in the rental house, and there were no unusual corners. Fortunately, what they are looking for is not only bloodstains, but also the DNA of the deceased. If it is true that Li Xiang is a suspect, then the biological traces of the deceased are not as easy to dispose of as blood.

Zhang Chenzhi's gaze quickly fell on the big closet in the corner. When he entered, he found two pairs of women's shoes on the shoe rack at the door. Although I have no idea about the size of a woman's feet, it is not much different from the size of the deceased. Now, after waiting for the traces to be detected, he can safely step in and check whether there are other clues in the big closet that can correspond to the evidence obtained at the scene in the early stage.

"It's not a good time to survey at noon." Shi Yan said softly. Her goggles-wearing face was as close to the ground as possible, and luckily there was a strong enough alternative light source. In the wavelength spectrum range of electromagnetic energy, whether it is bone fragments, body fluids, fibers, etc., the electrons in them can be excited and release unique light, which can be seen at a glance under the ultraviolet lamp.

Qiao Zhen carefully put on the hair cover so that her long hair would not be confused with the hair strands on the scene, and at the same time she wore goggles, she didn't want to be burned by the light. The two of them lay on the ground infinitely close together and began to work earnestly, silently, like two human scanners, extracting traces inch by inch. This is how the technical surveyors hope to rely on this fragment of information, and when they return to the laboratory, they can hopefully form a new set of evidence, which can fix the suspect in the prosecutor's office.

Fluorescences of various shapes flashed in the room, and Zhang Chenzhi felt a little irrepressible excitement every time he was at this time. However, it was useless to be rejoicing, because at this stage, he understood that all they could do was extract and fix, and the results of the comparison would not be able to draw conclusions until they went back.

At the same time, every time a new trace appeared on the ground, Qiao Zhen persuaded himself to calm down and fully immerse himself in this strange light, even if his actions were no different from that of a blind dog looking for food.

Fortunately, the area of the room is not large, just over 20 square meters. "It's all right here, Team Zhang, you can come in." After about half an hour, Shi Yan turned off the instrument and said to Zhang Chenzhi.

Qiao Zhen, who got up quickly, was already looking at the closet, took out a hanging lady's coat from a pile of clothes, and asked, "Do you think this dress looks familiar?" ”

"We have similar styles of coats and hats in our physical evidence." Zhang Chenzhi reacted immediately.

Shi Yan was rummaging through the bedside table drawer, and turned her head to take a look: "That's right, that's it, I remember the pattern." ”

Qiao Zhen nodded: "But even if it is the right number, this kind of mass-produced clothes can't say anything." You have to collect it to see if there is any biological information such as hair and dander. ”

"I'm not sure which woman's clothes were, maybe the one in front of her was thrown into the trash." There was disdain in Shi Yan's tone, and her nose was still searching for something.

Qiao Zhen looked at her and asked, "Is there blood?" ”

"Maybe it's my delusion, I always feel that there are no corpses here." Although Shi Yan said so, she was still trying to catch the illusion of nothingness.

"Don't worry, you look for it slowly. Our men have stabilized him. In a short time, there is no way back. Zhang Chenzhi glanced at his mobile phone and told them.

"Look, there's folic acid capsules in the bedside table." Shi Yan carefully took out the bottle and unscrewed the cap, "I've taken the dose for at least ten days, and there are only two-thirds left in it." ”

Zhang Chenzhi rarely looked confused, and Qiao Zhen also looked at her in a daze, not knowing what to do.

"Folic acid is a vitamin that only pregnant women or those trying to conceive take to provide the fetus with the nutrients it needs. When I look at you, I just don't have experience. ”

"You're the tone of someone who came over." Qiao Zhen couldn't help but make fun of her.

Shi Yan inadvertently glanced at Zhang Chenzhi and explained to Qiao Zhen seriously: "I have learned it in professional classes, otherwise I wouldn't know." ”

All three of them knew in their hearts that this was a trivial potential clue, and it was even likely to be just a coincidence.

There weren't any group photos of people in love in the room, and in fact, not a single photo could be found. This room is more like a poorly maintained inn than a place for two well-lived young people.

"He seems to have regarded the logistics of the unit as an employee benefit." Qiao Zhen pulled out a roll of black garbage bags from the kitchen closet. They had seen the garbage bags in the KTV warehouse in their first form. A thick volume, in Qiao Zhen's hand, there are not a few left.

The key evidence to be looked for has not yet emerged. What exactly is direct evidence to connect tenants and suspects, and where is it hiding, in a corner of the room that can be seen at a glance?

"The furnishings are so simple, there is nothing obvious abnormal, and the routine on-site photography and trace evidence extraction have also been completed, is it time to withdraw?" Seok Yeon looked at her watch and suggested.

"If this is the first scene of the suspect's crime, it is necessary to search it carefully." Qiao Zhen is still in love.

"But at a glance in the house, what can be found? We just heard what the landlord said, two days ago, they moved a few pieces of furniture, even if this is really a crime scene, the things to hide have long been moved. Shi Yan was going to stride out.

Qiao Zhen insisted on refusing to leave, and his feet remained in place. Zhang Chenzhi noticed that Qiao Zhen's eyes had been unconsciously looking in the direction of the bed, but he didn't say anything because he wasn't sure enough.

He trusted her professionalism and instincts, and it was better to try it than to miss something, and there was nothing to lose, since disappointment was a natural part of detection. So he proposed, "Perhaps, now, it's time for us to take a look under the bed, and guess there will be some surprises?" ”

Qiao Zhen was a little surprised by his coincidence, and after noticing that he had guessed his own intentions, he not only smiled and agreed. Shi Yan, who walked to the door, stopped and sorted out her equipment, while waiting for them with some impatience.

Zhang Chenzhi motioned to Qiao Zhen to prepare the instrument for further investigation. Then, with a strong push of his muscular arms, the mattress and the wooden bed board were lifted by him at once, and a light gray was quickly raised, and Zhang Chenzhi held his breath and tilted his head, trying his best to avoid them.

Qiao Zhen noticed that there was indeed a storage space under the bed that was divided into two, and half of the area was empty, but the dust on the ground had been wiped away, and it seemed that something had been placed recently, so she quickly leaned close to the bed frame and poked her head in, and easily put the instrument close to the space under the bed.

Shi Yan glanced at Zhang Chenzhi without saying anything, and simply looked at it, it was not effortless to lift these two things, but he looked relaxed. Zhang Chenzhi realized Shi Yan's concerns, didn't look at her, and simply said to Qiao Zhen: "You operate as soon as possible, so that I can guarantee that the bed will not press you." ”

Qiao Zhen didn't care about the black pressure on his head, and a cramped aura poured out from under the bed, mixed with dust, dancing irregularly in the light waves. She didn't care so much, because by this time, she had already found a strand of hair.

Zhang Chenzhi saw her movements stagnant and asked, "What did you find?" ”

"A long hair." Qiao Zhen put the strands of hair in the evidence bag, "Interestingly, at least to the naked eye, this is different from the hair quality and color we found in the closet. ”

"He has two women, which is normal, not to mention that many people change their hair color a lot nowadays." Shi Yan said coldly.

"Hey, you should come and see here." Qiao Zhen interrupted her and reminded.

"What is it?"

"Until now, the first drop of blood found today." Qiao Zhen added quietly, "You probably want to ask, could this be menstrual blood." Rest assured, the answer will be known soon. Although her tone was the same as usual, she could feel the excitement beneath her calm through her rare self-questioning.
