The next day, Zhou Ning walked quickly to the laboratory department, and before she pushed the door in, Cui Lili opened the door.

"Sister Cui is early!"

"It came early enough, the results came out, CA125, carcinoembryonic antigen CEA, and squamous cell carcinoma antigen were not found, but there is something special in the poison reaction, you can see for yourself."

As she spoke, Cui Lili threw the report into Zhou Ning's arms, he quickly skimmed through it, and Zhou Ning's eyes widened in surprise after reading it.

The substances detected were: coumarins and immandiones.

Then listed a large list of trade name drugs that may have this kind of toxin, such as Rat Killing, Rat Killing Fan, Da Long, Stinky Dilon, Killing It, Enemy Mouse Sodium Salt, Chlorine Diorone, Zhou Ning thought about it for a while.

"Sister Cui's deceased body is not high in toxins, what do you mean is that he was poisoned for a long time, and the original drug has a delayed nature, and it usually occurs about a week after taking it, which can explain the symptoms of gastrointestinal and bronchial bleeding."

"Last year, I did a eucalyptus test, and at that time it was stink, and this rodenticide is still relatively easy to obtain, and the murderer is the drug stolen from the pig farm."

Zhou Ning smiled gratefully at Cui Lili, although Cui Lili was very cold on the surface and did not smile, but she never dropped the chain when she tested the above things.

"Thank you, Sister Cui, by the way, this USB drive is for you, a teacher of mine specialized in testing and testing poisons before going abroad, and he has some experience, this was sent to me a few days ago, and they are some of the most advanced testing methods and comparison methods in the world."

Cui Lili paused and reached out to take the USB drive.

"Thanks, I'll go back and see."

Zhou Ning didn't stay long, and left directly, in fact, the things contained in the USB drive were all used by him to analyze and sort out the poisons learned in the system by virtue of his memory, after all, it was published in 2022, and after all, it was a more advanced test and comparison method than now.

Zhou Ning walked quickly to the first brigade of the criminal police, the door of the conference room was wide open, and there were several people sitting inside, smoky, and they felt blocked from breathing when they approached.

However, a few case bags on the table attracted Zhou Ning's attention, and Xu Dayuan waved his hand at Zhou Ning.

"Come in and sit, what did you find?"

Zhou Ning was not polite, went to open the window of the conference room, and then returned to the table and placed a stack of reports in front of Xu Dayuan.

"A second investigation was conducted in the deceased's vehicle, and no fingerprints of the second person were found except for the fingerprints of the deceased, to be precise, except for the door, steering wheel, gear lever, and safety leader, no fingerprints were found, and the interior of the vehicle was carefully cleaned."

Xu Dayuan was stunned, although there was no substantive discovery of this news, it showed that the murderer or the person who planned all this had a strong sense of anti-reconnaissance, and knew that leaving fingerprints would arouse suspicion.

"Amazing, huh? Anything else you found?"

Zhou Ning didn't answer, but opened all the case bags on the table, with the names of major hospitals on them, and the film would be given to such plastic or kraft paper bags, each with Zhang Guanglei's name written on it, obviously Zhang Guanglei has always felt that he is sick, and he is very sick.

"This was found in the deceased's house? Where are they hiding?"

Xiao Liu smiled, this girl has a quick mouth.

"At that time, I patronized the water valve, and the search was not careful, and these things were hanging behind the door of the second bedroom, blocked by some clothes and calendars, so I didn't find them."

Zhou Ning had already taken out various diagnosis books at this time, and read them again, and the patient's complaints were that he began to have nosebleeds, headaches, stomach pains, coughing up blood, occasional blood in the stool, and hair loss in February 2010.

Of course, the diagnosis of major hospitals is followed, and the content is similar, some of them have been prescribed drugs that affect the nerves to protect the gastrointestinal mucosa, as well as drugs that suppress cough and soothe smooth muscles, and even a doctor suggested that he go to the psychiatric department.

Zhou Ning put down these diagnosis books and put the test report in front of Xu Dayuan.

"It seems that the deceased found that his body was abnormal, and the test results have just come out, and the blood and organs in the heart of the deceased contain coumarins and imprinted diones, but the cumulative amount is not very large.

Oh, and forgot to introduce, this is an anticoagulant rodenticide, for example

Rat killing, Dalong, is a kind of chronic poisoning poisoning, generally six or seven days after taking effect.

Obviously, this poisoning process was very long, and the murderer did not want to be suspected, judging from the time he went to diagnose, the deceased had at least discovered that his body was abnormal, and it had been more than a year, and if it had not been for a long period of close contact, it would not have been possible to maintain the effect of the medicine in this way."

Xu Dayuan nodded.

"This analysis makes sense, it seems that we still have to look for clues from the private life of the deceased, and Zhenshan has replied to the news?"

Xiao Liu shook his head.

"Nope."

Zhou Ning rubbed his nose, he knew that Xu Dayuan was in a hurry, but it was not a matter of urgency.

"Otherwise, I will ask Da Zhao and Sun Gao Tie to go to the deceased's house to have a look and check the fingerprints left at the scene."

Xu Dayuan nodded.

"Yes, Xiao Liu, you go to the technical department with Forensic Doctor Zhou, and then Da Zhao and Xiao Sun, go to the deceased's house to have a look, the fingerprints on the car are so clean, there may not be anything left at home, but it's better to take a look at it and rest assured, by the way, call up the monitoring, the monitoring of the community, there is no dash cam or anything on the deceased's car?"

Zhou Ning shook his head.

"No, I checked this at the time."

"Okay, let's go, Mr. Xia, their animation is out, tell me as soon as possible."

Zhou Ning didn't expect that Xu Dayuan still remembered this stubble, nodded and took Xiao Liu away, and when he arrived at the technical department, Da Zhao and they had already come down, in fact, her name was Xiao Liu, she was two years older than Zhou Ning, her real name was Liu Yufei, it is definitely not easy for a capable criminal police girl, I heard that Liu Yufei's skills, few men in the team can beat it.

"Forensic Doctor Zhou, then I'll take Da Zhao and them."

Saying goodbye to Liu Yufei, Zhou Ning went upstairs directly to the laboratory, Liu Yongxin stood next to the computer, and said something to Xia Momo, Xia Momo's hand kept flying on the keyboard, the speed of this input was not worse than Xiaoqu, the more he found out, the more ashamed Zhou Ning felt ashamed of his prejudice at the beginning.

Gently opened the door and walked straight over, Xiaoqu saw Zhou Ning first.

"Forensic Doctor Zhou, you're here!"

Zhou Ning nodded with a smile, Xia Momo found Zhou Ning and looked at him with a smile.

"It just so happens that the animation has been completed, and according to the degree of damage to the vehicle, as well as the distribution of forces in various aspects, we have synthesized this animation, you can take a look at it first."

Zhou Ning walked closer, Xia Momo began to click play, and a black Sonata on the screen hit the street lamp pole directly, and the first impact caused the upper part of the street lamp pole to break directly and fall into the distance.

Inside the car, the driver was lying on the steering wheel, and there was a fracture sequence, of course, the fracture of the left temporal region, which was marked as the original fracture and was not recorded in this parameter.

The deceased's chest was fixed by the steering wheel, Zhou Ning squinted, according to this degree of impact, even if he was unconscious, he might wake up, but he was caught to death, even if he wanted to call for help or escape, he couldn't do it, after all, the mobile phone was not around.

At this moment, the rear of the Sonata was hit by the white Wrangler, the height of the Wrangler was much higher than the Sonata, so the squeeze on the pull was even more severe, the space in the Sonata cab was cut in half, and the front engine part was completely wrapped around the street light pole.

With such a shock, the broken street lamp pole fell off from the broken position, smashed through the windshield of Sonata, and poked directly into the face of the deceased.

However, the degree of injury of the Wrangler driver in the rear was not as serious as Zhang Guanglei's, why didn't he call the police or call an ambulance as soon as possible?

Zhou Ning was thinking about it, the Wrangler was hit sideways, and the butt of the car was thrown directly into the driveway, and then seven or eight cars appeared behind him, like dumplings, and crashed directly into the Wrangler's car.

Such a chain reaction was very fast, and Zhou Ning also realized that if the Wrangler fled as soon as possible, it was still possible to survive.

It can be seen that it is unlikely that the Wrangler deliberately hit Zhang Guanglei, and it is unbelievable to be sideways.

After the animation is demonstrated, Sonata is so compressed, the most important impact is in the last chain reaction, of course, the Wrangler's driver Sun Manqing also died because of the last impact.

"At this interval, did you check the section of the road that wasn't covered by the fog?"

Xia Momo smiled and glanced at her.

"What

I can't hide it from you, we called up the road surveillance footage on the 100-meter section east of the accident site, and the speed and interval were all obtained from that video, but to my surprise, the last car couldn't see the driver clearly."

Zhou Ning was stunned.

"What does it mean to not be able to see the driver? Didn't we fix it with our software?"
