"I can only try to restore it as much as possible." Joe really doesn't forget to be humble when necessary.

"You see, the damage to the blood stains is mainly due to the repeated crushing of cars, and there are bloody wheel prints that resemble bicycle wheels and messy pedestrian footprints on its sides. However, there are many long spikes on both sides of it, the spine body is thick and powerful, the longitudinal angle is relatively low, and the shape is relatively regular and similar, indicating that it is almost wiped out of the ground. ”

The two looked carefully in the direction she was pointing.

She continued: "The lateral angle of the blood stain is relatively large, and it should be formed by the squeezing of a heavy object with considerable velocity. The wheel print shows that the wheels are parallel, and the width between the two wheels should be 95 centimeters, which should be a small tricycle. ”

"Even then, you can't assume that this is the first scene, can you?"

"In my opinion, first of all, this is not a scene at all, because this is not a case, not only is it not a traffic accident, but it is not a road section for throwing corpses, not to mention what relevance it will have to do with our case."

Zhang Chengcheng stepped forward and asked, "How do you say this?" ”

Qiao Zhen leaned closer to the ground and pointed to a place to show them: "First of all, this is not a traffic accident. There was no human tissue, no hair, and no blood stains on the injured people at the scene, and there was no information about the traffic accident last night after the on-site visit. ”

"So in your judgment, it's not the corpses that are being transported?" Zhang Chengcheng reacted quickly.

Qiao Zhen glanced at him appreciatively, nodded and said, "Neither is it a traffic accident, nor is it the scene where the vehicle hits the animal, so the remaining possibilities are nothing more than throwing corpses and transporting goods to shed blood." How can we rule out the possibility of throwing corpses?"

"yes, how did you rule it out? Now that the blood sample is seriously contaminated, it is difficult to distinguish it from the perspective of forensic medicine, and it is only up to your judgment. Chen Shijie couldn't wait to ask.

Qiao Zhen didn't answer him directly, but walked straight to the side of the sewage ditch and pointed out a few blood stains on the wall of the sewage ditch to show them: "You see, is there any difference in the shape of this blood stain?" ”

Chen Shijie really couldn't see any eyebrows, and quickly shook his head. Zhang Chengcheng also smiled and waited for her to throw out the answer.

"Judging from the shape of the bloodstains, their angles are flat and straight, and they are thrown out, what kind of things can be thrown out like this? Apparently the same lightweight object. ”

"Moreover, most of the walls outside the ditch have blood droplet marks, indicating that this person did not come here when he threw the bag, but was quite a distance away." Zhang Chengcheng squatted down and stretched out his fingers to gessy.

Qiao Zhen nodded: "This shows that at that time, the bag was actually empty." And, going back to the blood ribbon just now, have you noticed such a feature? The blood drops went from dense to thin, and there was no third similar blood wheel mark. ”

"You're saying that the blood itself was on the car, not over the pool of blood, because if it had been over the pool of blood, there should have been three blood marks. But what does this have to do with not transporting corpses? Chen Shijie asked.

"Of course there is, so that it can be concluded - the means of transport is a small tricycle. Of course, this conclusion is also deduced from many factors. You see, there are only two blood marks that indicate that the blood is on the rear pallet, and during the ride, of course, only the back two wheels will be pressed. And because of the on-site shape, it can be judged that the blood flow was rapid and uneven at that time, indicating that the supporting plate behind it has no sealing, and generally only the rear board of the tricycle transporting goods is simply spliced with wooden boards. Coupled with the fact that the snakeskin bag was judged to be empty before, and the fact that it is close to a densely populated area, I can make an inference. Although it is bold, I am confident that I will not be far from ten. Qiao Zhen wrapped his coat tightly, stroked his hair that was blown by the wind, and looked at Zhang Chengcheng as he spoke.

Zhang Chengcheng shrugged: "Don't be afraid of us being disappointed, there are no twists and turns in the process of handling the case, we will all be unaccustomed to it, just say it." ”

"Team Zhang, I suggest that the comrades on the periphery go to verify as soon as possible whether there is a vegetable farm nearby, this road is the only way to transport goods from the suburbs to the vegetable field, if so, there should be a person transporting chicken and duck blood or other poultry blood riding through here, but accidentally spilled the blood, not as we originally imagined."

Zhang Chengcheng nodded, pursed his lips, and stopped talking.

At this time, the sky was already dark, the wind was getting stronger, the typhoon was coming, and it was time to close the team, but this case was far from "everything is ready".

Zhang Chengcheng got into the car a little silently, and there was no one in the car. He is too familiar with this kind of atmosphere, every time he solves the case to the point of stalemate, extreme fatigue and the moment before the arrest, it is this kind of silence, but today's atmosphere is the most dull and depressing, and even Chen Shijie, who has always been full of bright smiles, looked out the window seriously.

Zhang Chengcheng thought about it, and couldn't help but glance back at Qiao Zhen. Usually, she is probably influenced by the culture of studying in the United States, she has a lot of body language, and she is still an expression emperor, and it is rare to see her unique demure appearance of an oriental girl at the moment.

This girl seems to have many facets, and the focus and professionalism at work today is even more impressive. And his master who is not angry seems to be two extremes, one is complex to pure, and the other is so transparent that it is confusing, and he can never guess which brand new Qiao Zhen he will see next time.

During the rush hour, a car of people is stuck in the traffic and cannot move. Zhang Chengcheng had already estimated this, and only reserved a few colleagues who had to return to the unit, and the others went separately to investigate and visit the area around the blood belt, while another group of mobile troops stayed in the bureau and stood by. In this way, when something happens in a hurry, no police force will be wasted.

Sure enough, a series of phone calls woke him up immediately after falling into a light sleep. The news came from the scout at the front, which coincided with Qiao's real judgment, and that's it.

Another piece of news suddenly made him completely sleepy: Zhang Qin's corpse, to be exact, - part of the broken corpse was found!

Shi Yan, who was working overtime in the unit, and Chen Shijie, who went home on his own, immediately rushed to the scene. The staff of the housing management office who found Zhang Qin's head and upper limbs cut off were as earth-colored, and they were still slumped on the ground retching. After Shi Yan looked for him to get a general understanding of the situation, she entered the cordon. This is the middle floor penthouse of a high-rise apartment.

Shi Yan clearly remembers that someone committed suicide by jumping off a building here a few years ago, when she was still a trainee policeman, and she followed the master to the scene of the first high fall, which was naturally bloody and unforgettable.

A thick, oversized black plastic bag was fished out of the tank, the bag had been opened, and the first thing that came into view was a large messy mass of black hair, followed by a very uneven neck, and the disgusting cortex, fat, and bones were clearly visible from the cross-section, and the blood in the bag had flowed.
