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

Then began to compare further, which was quite fast, with an interface opened, and the large screen was full of various fingerprints, as well as the results of the comparison in the four cars.

Zhang Guanglei's Sonata car, found Wang Wenjing and Wang Mengmeng's fingerprints, but they were all mutilated, and they were covered by his own fingerprints, apparently left for a long time, after all, his car was the most damaged, and the part that could be extracted was limited.

As for the interior of Sun Manqing's Wrangler, the fingerprints are relatively rich, including Yu Meimei, Chai Ruhua, Chai Father, and Sun Yannian, and the fingerprints in Honda's car are Sun Yannian and Wang Mengmeng.

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

Liu Yongxin rubbed his chin and sighed.

"This relationship is complicated enough, but according to the results of the current investigation, Wang Mengmeng and that Sun Yannian are very suspicious, even if they are not murderers, they are also participants, Xu Da said that he didn't say it, how is this Sun Yannian's investigation?"

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

"I didn't ask, I guess I sent someone to investigate, there are so many existing conditions, we still have to dig deep into the clues, the deceased has Da Long in his body, but this has not been found in the homes of these suspects.

And he has been poisoned for a long time, since last year, he has coughed up blood and vomited blood, which shows that he has been exposed to this substance, and he is poisoned very slowly, so I just suspect that I am sick, and after a while, Da Zhao will contact Xu Da and ask him to send someone to take you to the deceased Zhang Guanglei's house to check, of course, Sun Manqing's family will also go to see. ”

Da Zhao nodded, dialed Xu Dayuan's phone, and the other party agreed, after all, he took the initiative to participate, no one shirked it, let Da Zhao go downstairs and wait, and Bai Ruixin followed him in a while.

Zhou Ning looked at Sun Tie and waved his hand at him.

"You take the survey box and take a trip with Zhao Traces, and Da Zhao asked Director Pang to ask him to transfer two traces to go with you, we have few people, and this eucalyptus is also a cooperation between our two groups, so naturally we have to send people."

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

"You want to check that accident car again?"

Zhou Ning nodded.

"There is no clue, that is, we are looking for unfavorable, Master said, where there is contact must leave traces, there must be something we ignore, the murderer caused a car accident, naturally hoping that the car would crash or even explode, when we arrived at the scene, but we smelled a strong smell of gasoline, so that everything could be destroyed, but there was no explosion at the scene, and the fingerprints that can be extracted from the vehicle are also very limited, I want to see again."

Liu Yongxin paused and waved his hand at Xia Momo.

"Don't worry, Mr. Xia, you put that animation aside, it's the animation you simulated the crash damage sequence."

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

"Slow down, slowest speed."

Xia Momo adjusted the animation to the very beginning, and then clicked eight times the speed to slow down.

The car hit the street lamp pole from the rightmost lane of Lijiang West Road, and Zhou Ning had doubts in his heart when he saw this, and Liu Yongxin stopped directly.

"Stop!"

Then he looked at Zhou Ning, and seeing that Zhou Ning was deep in thought, he looked at Zhou Ning with a smile without speaking, obviously hoping that Zhou Ning would say his doubts.

"The deceased Zhang Guanglei had been poisoned for a period of time, his organs were damaged, his stomach was bleeding and atrophied, and his peptic tract bleeding ulcers formed mucus accumulation, according to the results of laboratory tests, it was not a manifestation of acute poisoning, and his head was also hit.

In such a situation, how can you control the vehicle to quickly hit the street light pole? Causing such an impact and vehicle damage, I think Mr. Xia has already estimated his speed, right? ”

Xia Momo nodded.

"The minimum speed of the car should be forty, but it will not exceed fifty miles, if it is this speed, plus the continuous impact of the rear, the folding of the cab will be more serious, and it is more likely to roll over, but the second or third impact behind the deaths will be more."

Liu Yongxin snapped his fingers on the side, obviously he had thought of this just now.

"Okay, now the problem is, the deceased suffered a heavy blow to the position behind the temporal ear, according to the autopsy, the injury has injured the head and caused a coma, you said during the autopsy, maybe the deceased's leg was fixed here, and he kept stepping on the accelerator.

I don't rule out doubts about that, but I think immobilizing the deceased's leg would at least leave a strangulation mark or something, but we didn't find it. ”

Zhou Ning nodded.

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

The three of them went downstairs and went directly to the garage requisitioned by the laboratory, where the accident car that had been cut open was suspended inside, and the three of them began to observe carefully.

Liu Yongxin gently knocked on the driver's door with the brush in his hand, and there was a rattling sound inside.

"At the time of the car accident, the window glass was retracted, so there was not too much glass puncture wound on the left side of the deceased in the car accident."

This discovery made Zhou Ning stunned, the window was not closed, that is, it could be operated in this position, maybe the impact injury was also caused at this time, so if the leg was not fixed, with supports, it was also possible to fly out of the car after the impact, of course, the biggest possibility was to be squeezed in the driver's seat.

Zhou Ning squatted down, the brake and accelerator had been squeezed upside down in the small space in front, they had all been sampled here before, Zhou Ning rubbed his gloves with both hands, reached out and touched the accelerator pedal, the pedal that had been deformed, pulled it a little harder, and fell it 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 hurriedly pinched the magnifying glass and looked at it, and instructed Zhou Ning:

"Go get luminol reagent, why do I look like blood?"

Zhou Ning didn't delay, he quickly took the luminol reagent and sprayed it on the pedal, and then got the location of the scratch, fluorescence appeared, Zhou Ning was overjoyed, and quickly grabbed a physical evidence bag.

Liu Yongxin threw the pedal inside, and then looked at the location where the pedal was found.

"Keep looking, the tool that Che Xiaoqu borrowed from Qin Da yesterday has restored the squeezing state of the car a bit, see if you can find something else, the height of this pedal, if you use something to stop, it is not so easy to throw out."

This idea coincides with Zhou Ning.

Zhou Ning simply knelt on the ground, poked his head into the gap that was stretched open, held a strong flashlight, and observed carefully, just when he looked at the position at the bottom of the dashboard, a hammer head appeared in the gap.

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

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

"I didn't expect that in the center of the extrusion, there was a hammer wrapped around it, and only the twisted engine could be seen on the X-ray, but no hammer was found, and there were hydraulic tongs here, and we could try to break through the dashboard and take the hammer out from above."

Zhou Ning nodded, went to bring the hydraulic tongs, Xia Momo intimately searched for the use of the hydraulic tongs, and distributed a goggle to the three of them, after a study, Zhou Ning held the hydraulic tongs and inserted the head into the part that had been shattered above, with a burst of noise, the dashboard made a snap, and there were cracks everywhere.

Liu Yongxin hurriedly waved his hand.

"Stop, stop, don't get it, this guy is too big, it's broken everywhere here, it's safe to find this thing with a crowbar."

After some searching, among the tools left by Xiaoqu, he really found a crowbar, inserted it and broke it outside, the entire dashboard was shattered, and Liu Yongxin had already stepped on the chair and poked his body in.

"Pull me along."

Zhou Ning hugged Liu Yongxin's waist and pulled it back hard, and the two fell directly.

"Hey, my old waist!"

Zhou Ning was taken aback, after all, the master had a broken leg before, was injured by the explosion, and had a heart stent, so he hurried to check Liu Yongxin's condition.

"What's going on, Master?"

"I can't die, but you kid is dry and thin, why are you so vigorous, okay and take it out."

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

Seeing this, Zhou Ning's excited heartbeat accelerated, and he carefully packed it in a physical evidence bag.

"Master, let's take a rest first, I'll go up and take the fingerprints, and then send them to the laboratory to see if we can find the bloodstains, and then compare them with the skull injury of the deceased."

Liu Yongxin also smiled, leaned on his waist, and pointed to the bag of the pedal on the ground.

"Take this, go up together, it seems that the claw hammer is pinned to the gap between the accelerator and the side under the dashboard, but this automatic car, I don't know, can it be started like this?"

Zhou Ning nodded.

"This is an automatic car, the car will not rush out if you press the accelerator alone, you must step on the brakes, the window of this driver's seat is open, as long as someone presses the brake with a long pole, adjusts the direction, as soon as the brake is released, the car rushes out, if you can find fingerprints, then the murderer will also surface."

Liu Yongxin shook his head.

Zhou Ning looked at Liu Yongxin with some puzzlement, didn't he agree with his own point of view?

"Let's find it first, I think the murderer can design such a car accident to confuse everyone, and he will never leave his fingerprints and wait for you to arrest him, right?"
