Chapter 146 Found it

Sun Gaotie went to submit it for inspection, and Xia Momo entered the fingerprints collected by Zhou Ning one by one.

Then further comparison began. The speed was quite fast. As an interface opened, various fingerprints were displayed on the large screen, as well as the comparison results corresponding to the four vehicles.

"The fingerprints of Wang Wenjing and Wang Mengmeng were found in Zhang Guanglei's Sonata, but they were all incomplete and covered by his own fingerprints. Apparently they had been left there for a long time. After all, his car was the most severely damaged and the parts that could be extracted were limited.

As for the fingerprints inside Sun Manqing's Wrangler, the fingerprints are relatively abundant, including the fingerprints of Yu Meili, Chai Ruhua, Chai's father, and Sun Yannian. The fingerprints in the Honda car include those of Sun Yannian and Wang Mengmeng.

In the end, Wang Wenjing and Wang Mengmeng’s fingerprints were found on Chen Chunxi’s Santana, as well as many, many unknown fingerprints.”

Liu Yongxin rubbed his chin and sighed.

"This relationship is complicated enough, but according to the current investigation results, Wang Mengmeng and Sun Yannian are highly suspected. Even if they are not the murderers, they are still participants. Has Xu Da said anything about the investigation of Sun Yannian?"

Zhou Ning shook his head. He just listened to Chen Chunxi's inquiry directly and went to see the car, but he didn't ask this question.

"I didn't ask. I guess we sent someone to investigate. There are only so many existing conditions. We still need to dig deeper for clues. There was Dalong in the body of the deceased, but this was not found in the homes of these suspects.

And he had been poisoned for a long time. He had coughed up blood and vomited blood since last year, which meant that he had been exposed to this substance and was poisoned very slowly. Therefore, I just suspected that he was sick. Da Zhao would contact Xu Da soon and ask him to

Send someone to take you to the deceased Zhang Guanglei’s house to check, and of course Sun Manqing’s house will also have a look.”

Da Zhao nodded and called Xu Dayuan. The other party agreed. After all, he took the initiative to participate. No one could shirk it. He asked Da Zhao to go downstairs and wait. Bai Ruixin would follow him later.

Zhou Ning looked at Sun Gaotie and waved to him.

"You take the investigation box and go with Zhao Henjian. In addition, Zhao asked Director Pang to assign two trace inspectors to go with you. We have few manpower. This case is also a collaboration between our two teams. Naturally,

We also need to send people.”

Da Zhao dragged Sun Gaotie away, and Liu Yongxin looked at Zhou Ning.

"You want to check the car that was involved in the accident again?"

Zhou Ning nodded.

"If we don't have any clues, it's just a disadvantage for us to look for it. Master said that any contact will leave traces. There must be something we have overlooked. When the murderer caused the car accident, he naturally hoped that the car would crash or even explode. When we arrived at the scene, but

I smelled a strong smell of gasoline, which can destroy everything, but there was no explosion at the scene, and the fingerprints that could be extracted from the vehicle were very limited. I want to see it again."

Liu Yongxin paused and waved to Xia Momo.

"Don't worry, Mr. Xia, please put that animation aside. It's the animation where you simulated the sequence of car crash injuries."

Xia Momo found the animation and clicked to play. Liu Yongxin kept waving.

"Slow play, play at the slowest speed."

Xia Momo adjusted the animation to its original state, and then clicked to slow it down at eight times speed.

The car left the rightmost lane of Lijiang West Road and hit the light pole. Seeing this, Zhou Ning had doubts and Liu Yongxin stopped directly.

"stop!"

Then he looked at Zhou Ning and saw that Zhou Ning was deep in thought. He looked at Zhou Ning with a smile without saying anything, obviously hoping that Zhou Ning would express his doubts.

"The deceased Zhang Guanglei had been poisoned for some time. All his organs were damaged, his stomach was bleeding and atrophic, and his gastrointestinal tract was bleeding and ulcerated to form mucus accumulation. According to the test results, it was not a sign of acute poisoning, and his head also suffered

blow.

Under such circumstances, how can one control a vehicle to hit a light pole quickly? As a result of such a collision and damage to the vehicle, I think Teacher Xia has already estimated his speed, right?"

Xia Momo nodded.

"The speed of the vehicle must be at least 40, but it will not exceed 50 mph. If it is this speed and there are continuous impacts from the rear, the folding of the cab will be more serious and it will be more likely to roll over. Instead, it will cause a second crash from behind.

Three impacts, more people died."

Liu Yongxin snapped his fingers aside, obviously he had thought of this just now.

"Okay, now here's the problem. The deceased was hit hard in the temporal area behind the ear. According to the autopsy findings, the injury had already damaged the brain and caused coma. During the autopsy, you said that maybe the deceased's legs were fixed here.

, keep pressing the accelerator.

I don’t rule out this suspicion, but I think fixing the deceased’s legs would at least leave strangulation marks or something else, but we didn’t find any.”

Zhou Ning nodded.

"Then let's go take a look at the accident vehicle."

The three of them went downstairs and went directly to the garage requisitioned by the laboratory. The cut-up accident car was suspended inside. The three of them began to observe carefully.

Liu Yongxin gently knocked on the driver's door with the brush handle in his hand, and a splashing sound came from inside.

"At the time of the car accident, the window glass was folded up, so there were not too many glass stab wounds on the left side of the deceased during the car accident."

This discovery made Zhou Ning pause. If the window is not closed, it means that it can be operated in this position. Perhaps the injury was caused at this time, so instead of fixing the leg and using a support, it would be okay to fly out of the car after the impact.

It's possible, of course, the biggest possibility is that it will be squeezed in the driver's seat.

Zhou Ning squatted down. The brake and accelerator had been squeezed into the small space in front. They had taken samples here before. Zhou Ning rubbed his gloves with his hands and reached out to touch the accelerator pedal. He picked the deformed pedal with a little force.

It fell down with a snap.

Zhou Ning picked it up and looked at it carefully, and seemed to see a scratch on it.

"Master has scratches!"

Liu Yongxin quickly took a look with the magnifying glass and ordered Zhou Ning:

"Hurry and get the luminol reagent, why does it look like blood stains to me?"

Zhou Ning didn't waste any time, and quickly took the luminol reagent and sprayed it on the pedal. Then he took the scratched position and saw fluorescence. Zhou Ning was delighted and quickly grabbed an evidence bag.

Liu Yongxin threw the pedal inside and then looked at where he found the pedal.

"Keep looking. The tool Xiaoqu borrowed from Qin Da yesterday has restored the car's squeezing state. Let's see if we can find anything else. The height of this pedal is not so easy to get rid of if it is pinned with something.

Out."

This idea coincides with Zhou Ning's.

Zhou Ning simply knelt on the ground, put his head into the stretched gap, held up a strong flashlight, and observed carefully. When he looked at the bottom of the instrument panel, a hammer head appeared in the gap.

"I found what seemed to be the head of a hammer, but it was completely squeezed into the gap."

Xia Momo came over and looked at the machine next to her.

"I didn't expect that the center of the squeeze was wrapped with a hammer. Only the twisted engine could be seen on the X-ray, but no hammer was found. There are hydraulic clamps here. We can try to break open the instrument panel and get the hammer from above.

come out."

Zhou Ning nodded and went to pick up the hydraulic pliers. Xia Momo carefully searched for how to use the hydraulic pliers and distributed a pair of goggles to each of the three of them. After studying for a while, Zhou Ning held the hydraulic pliers and put her head on the head.

Insert the broken part above, and with a series of sounds, the dashboard clicks, and there are cracks everywhere.

Liu Yongxin quickly waved his hand.

"Stop, stop, stop. This guy is too big. Everything here is in pieces. It's safe to look for something like a crowbar."

After searching for a while, I found a crowbar among the tools left by Xiaoqu. I inserted it and broke it outward. The entire dashboard was shattered. Liu Yongxin had already stepped on the chair and leaned in.

"Hurry and pull me."

Zhou Ning hugged Liu Yongxin's waist and pulled him back hard, causing the two of them to fall down.

"Oh, my old waist!"

Zhou Ning was shocked. After all, his master had broken his leg before, was injured by an explosion, and had a heart stent. He quickly checked on Liu Yongxin's condition.

"How are you doing, Master?"

"You can't die, but you are so skinny, why are you so energetic? Come on, take it out."

Only then did Zhou Ning discover that although Liu Yongxin fell down, he was holding a broken claw hammer in his hand.

Seeing this, Zhou Ning's heartbeat accelerated with excitement, and he packed it carefully in an evidence bag.

"Master, let's take a rest first. I'll go up and extract the fingerprints, and then send them to the laboratory to see if blood stains can be found, and then compare them with the skull injuries of the deceased."

Liu Yongxin also smiled, holding his waist and pointing to the pedal bag on the ground.

"Take this and go up together. It seems that you use a claw hammer to fix it in the gap between the accelerator and the side under the instrument panel. But I don't know about this automatic car. Can it start like this?"

Zhou Ning nodded.

"This is an automatic car. Just press the accelerator and the car will not go out. You have to press the brake. The driver's window is open. As long as someone presses the brake with a long pole and adjusts the direction, it will release.

Brake and the car will rush out. If fingerprints can be found, the murderer will also surface."

Liu Yongxin shook his head.

Zhou Ning looked at Liu Yongxin with some confusion. Did he not agree with his point of view?

"Let's look for it first. I think the murderer can design such a car accident to confuse everyone. He won't leave his fingerprints behind and wait for you to catch him, right?"
