"Pushing baggage, do you mean someone pushed the corpse all the way over?"

Zhang Lei understood what Xiao Ran meant, but felt a little inconceivable: "Pushing a corpse on the road, how can this car come and go!"

"The human push speed is too slow, and the wear and tear is not to this point. ”

Xiao Ran shook his head and said: "It may also be that it was stuck by the chassis of the car, rubbing and squeezing all the way, and the body was worn thin, and it was detached from the ground." ”

"You mean it's a traffic accident?" Zhang Lei said.

Xiao Ran continued to shake his head, "There will definitely be an impact in the traffic accident, but except for the broken skull, the other important bones of the corpse are not broken...... Let's go to the first scene. ”

"First, the first scene?"

Zhang Lei was a little confused, "How do you know where the first scene is?"

"Feeling. ”

Xiao Ran nodded, "Maybe there will be a discovery?"

After talking to Pang Jinghui and borrowing a battery car, Xiao Ran observed the direction of wear and tear of the corpse's bones, and drove Zhang Lei all the way north along the provincial road.

Walking along the road, there were no suspicious traces except for the fields and villages on both sides of the road.

Zhang Lei sat in the back seat, looked at the dashboard with only 40% of the power left, and said: "Xiao Ran, I think let's go back, we have walked almost 15 kilometers, and the battery car is almost out of power." ”

"After this town, I didn't find it again and went back. Xiao Ran said.

"Hmmm......"

Zhang Lei agreed, but in an instant, his eyes were attracted by a trace under the hill in front of him.

Zhang Lei stared at the 20-meter-long trail of blood, patted Xiao Ran's shoulder excitedly, and shouted: "Xiao Ran, look at it, this bloodstain ......."

"It is likely to be related to the deceased, go down and take a look. Xiao Ran had an excellent field of vision, and naturally saw the bloodstains from a distance.

In the process of on-site reconstruction, bloodstains are a very important part of it, each bloodstain has its own trajectory, and the analysis of each bloodstain can restore the way the body was damaged.

Xiao Ran looked around, this is located on the east side of the road, the west is the guardrail, the east is the mountain, and there is a bend of not very large to the north.

Walking north along the bloodstains, the bloodstains turned from light to thick, and a large number of bloodstains and corn stalks were scattered on the ground.

Because of the bloodstains on the destruction of vehicles passing by, it can only be barely seen that there is a central pool of blood on the side of the mountain near the road.

There are a large number of splashed blood stains around the blood pool, and the blood pool in the center coincides with the corn stalk, and the wiping blood stains formed by the corn stalk can be seen, and there are flow blood stains on the drainage ditch wall near the mountain.

There are tire marks on the journey of the vehicle's tires after the blood pool is crushed by the vehicle's driving direction, and long drag blood marks suspected of being dragged by the corpse can also be seen.

Xiao Ran carefully inspected the scene, and frame by frame quickly built up in his mind.

The appearance of the central blood pool indicates that the injured person has stayed here for a long time, and the surrounding splashed blood stains are formed by the vehicle running over the blood pool or crushing the injured person, because the directionality of the splash is very single, and they all point to the central blood pool.

The bloodstains on the mountain should be formed after the blood in the central blood pool splashed down on the mountain, the wiping blood stains should be left by the corn stalks on the blood pool driven by the vehicle, and the dragging blood stains about 20 meters long to the south should be left by dragging the corpse to Jiang Village.

"Xiao Ran, look!"

Zhang Lei exclaimed, Xiao Ran immediately walked over, only to see that about 3 meters away from the blood pool in the center, there were some things suspected of fragmenting brain tissue and bone fragments.

Moreover, in the drainage ditch near the side of the mountain, Xiao Ran found three pieces of broken plastic with a size of about 3 mm, which were suspected to be the material of the headlights.

"Report to the Lei Brigade immediately, this is very likely to be the first scene!"

Soon, the Lei brigade who received the news rushed over, and other colleagues quickly pulled up the cordon, Lei Kang looked at the traces of the scene, nodded and said, "Yes, this is likely to be the first scene...... Forensic Doctor Xue, you quickly extract samples for DNA comparison, Shao Yong, you come and reconstruct the scene with me to see if there are any special blood stains!"

The so-called special bloodstains are bloodstains that cannot be associated with the bloodpool and other bloodstains through the movement trajectory after the bloodstains at the scene are restored through the movement trajectory.

Each drop of blood has its own trajectory, but the scene has been run over by various vehicles - just like a quagmire that has been jumped by a child a few times, rolled around, and then washed away by a car several times, trying to find a drop of mud around the quagmire with a different trajectory, the degree of metamorphosis can be imagined.

Similarly, the difficulty of restoring the bloodstains on the scene here is quite perverted.

"Lao Pang, Xiao Ran, you build a dragging route for the corpse, and see if the corpse has been following this road, and whether there is any change of line halfway. Lei Kang said to Pang Jinghui and Xiao Ran.

Pang Jinghui nodded, although most of the cases he dealt with in the third team were sneaky cases, he had also participated in a lot of such major murder cases, as an old criminal policeman for many years, what cases had he never seen?

"Xiao Xiao, find a suitable stick. ”

Pang Jinghui turned to Xiao Ran and said, since Xiao Ran fought for the face of the three teams last time, Pang Jinghui's attitude towards their young people has improved a lot.

Xiao Ran knew that Pang Jinghui was going to simulate the dragging trajectory, and soon found a moderate bamboo pole stick, he rode on the battery car, Pang Jinghui sat in the back, holding the bamboo pole in his hand, and put the end of the bamboo pole on the drag track on the road, and walked all the way south.

This is a two-way single lane, because there is a guardrail in the middle, so the vehicles on the road generally do not change lanes, fifteen kilometers feels very far, but the car actually does not take a few minutes to run.

Walking south along the first scene, the drag blood stains are very faint after 20 meters, and they are almost completely disappeared at 40 meters.

If the corpse really passed by here, there would still be blood stains in theory, but the blood stains were so faint that they could not be seen by the naked eye.

Xiao Ran and Pang Jinghui focused on observing the road conditions.

During the period, after passing two bridges, there are also several sections of the road surface fracture gap, the bridge deck has two metal-like protrusions at the junction, and there is a drop on both sides of the road surface crack.

If the corpse passes by, it may aggravate the friction, so in these places it is necessary to focus on wiping with a cotton swab, although there is no blood stain, but as long as the wiping range is large enough, the blood can basically be wiped out.

In this way, the two walked and stopped, from the first scene back to the second scene.

In the blink of an eye, it was already noon, and everyone who had been busy all morning hurried to the nearby police station for lunch.

Although the traces collected by Pang Jinghui and Xiao Ran on the road are still being tested, at this time, many people have already characterized this case as a traffic accident in their hearts.

After all, in the reconstruction of the first scene, no special blood stains were found, and there were fragments of car lights at the scene, and there were no other suspicious traces next to the continuous drag traces, which was very consistent with the consistent performance of traffic accidents.

And the next news from the traffic police seems to have verified everyone's speculation.

It was reported that a passenger car was found in a parking lot, with a large amount of blood stains under the car......
