Zhou Ning looked around and said quietly.

"Dalong belongs to the anticoagulant rodenticide, which is a chronic attack of drugs, this kind of drugs are fat-soluble, so when placed in water, it has no effect, it is completely insoluble in water, the first needs oil, and the second needs to act for a long time, so that Zhang Guanglei can be in contact all the time."

Da Zhao looked around expectantly, this person's kitchen was useless, it was impossible to find the spices and food, and the other items in the room were also checked, and nothing special was found.

Da Zhao was also a little anxious, and kept wandering around the room, after all, there were not many things that could be imported in this room.

"Is there anything special about the color, smell, and taste?"

"There is no special smell, and in the introduction of the poison, I remember that it says that it has good palatability, and as bait, it is not easy to be rejected, that is, it has no special taste, as for the gray-white powder in color."

Da Zhao paused, tilted his head to look at Zhou Ning, seemed to have thought of something, walked quickly towards the coffee table in the living room, and found a sorting box from under the coffee table, the huge box was full of medicine bottles.

There was a dazzling array of everything, Zhou Ning also walked over, threw aside the aluminum-plastic packaging, and found two white bottles without any printed packaging, on which Zhang Guanglei 2011.7 and Zhang Guanglei 2011.8 were written with a marker.

Open the bottle, there is no aluminum foil seal inside, they are all capsules, you can see that there is yellow-brown powder inside, and there is a piece of paper stuffed inside, Zhou Ning took it out with tweezers, and unfolded it to see that there was printed handwriting on it.

Take three capsules once a day at bedtime.

Da Zhao compared, the bottle in July was obviously less than the bottle in August, and in addition to this, there was no preparation in the box that was a capsule at all.

"Is this Da Long?"

Zhou Ning opened a capsule and dialed the powder, in the middle of the herbal powder, it was indeed mixed with an off-white and more delicate powder, and the properties were completely different.

"It feels like this thing is fat-soluble, if it is packaged separately, it has to be mixed with the medicine powder, and the capsules are packed by yourself, it is indeed easy to remain in the cracks of the nails, and it is easy to wash off, and the nails are in contact for a long time, Wang Wenjing may also have toxic ingredients in his body, and Wang Wenjing's blood will also be tested for poison tomorrow."

Da Zhao blinked.

"Alright, everything will not know until the test is done."

The two evacuated, and sent a message to Xu Da on the way, telling him that they had found some suspected medicinal powder mixed with Dalong here, and they needed to be tested to know the results, and Xu Dayuan asked them to go back first and talk about it tomorrow.

Da Zhao volunteered to deal with this matter and sent Zhou Ning home first.

......

Following.

As soon as he entered the office, Zhou Ning saw Da Zhao eating instant noodles, glanced at the table, a report was already on the table, and Da Zhao raised an eyebrow at Zhou Ning.

The face is full of expressions of you praising me, you praising me!

Zhou Ning couldn't help but laugh, this person's personality is really good, working with him, he will definitely not be affected by some negative emotions, after all, he can get you out of the haze in minutes.

"The test results are out? Didn't you tell Sister Cui yesterday that we won't send it for inspection at night, what excuse did you use? ”

Da Zhao grinned.

"What do you say? Am I that kind of person? We don't need an excuse, we just found someone on duty, took some food from Xu Da there, sent it directly, and then put the things down, and seriously stated that we would do poison analysis tomorrow, and today I have promised not to send it for testing with Sister Cui.

The man got into a fight with me, arguing for a long time, and then the machine was doing the test, and we ate two roast ducks and some other food, and the test was done after eating, and the results were already out, and the comparison was made.

The poison in the Chinese medicine powder is exactly the same as the poison found in the deceased's body and Wang Wenjing's hands, oh Wang Wenjing also has a certain amount in his blood, but it is slightly less.

There is also a test result, which is a little unbelievable, that is, Chen Chunxi scratched there in the car, and the blood stains were Sun Manqing's, white traces, consistent with Sun Manqing's Wrangler, I remember that in the surveillance, the Wrangler was hit sideways, but I couldn't see what car hit him, and he didn't find the vehicle at the scene, it seems that Chen Chunxi did it. ”

Zhou Ning glanced at the results, breathed a long sigh of relief, and waved his hand towards Da Zhaoyi.

"Let's go, Xu Da tossed all night, I guess I'll wait for this result, let's go over and take a look, by the way, Wang Wenjing and they brought it?"

Da Zhao shook his head.

"I tossed the inspection report and called Xu Da, but he couldn't get through, and I guess he was interrogating, so I didn't call again."

As he spoke, the two of them had already arrived in the front building, and as soon as they entered the office area of a large team, they heard a woman's scream, a crazy roar.

"Ahh You let go of me, I'm a patient, I can't move my legs, ah, where is your hand touching, I'm going to complain to you, how many are your alarms? ”

After a crazy output, many people in the entire corridor looked in the direction of the sound, and saw Wang Wenjing holding the door frame and calling for help towards the corridor.

Before Zhou Ning and the others came over, they saw Liu Yufei running two steps and kicking directly to the door, such a big movement startled Wang Wenjing, who was holding the door.

Da Zhao shrank his neck, Liu Yufei's actions were too strong, and they were far from his usual quiet appearance.

But if you think about it, you also know that a beautiful woman will never stay in the criminal police team because of her appearance, and just kick out the feeling of a black belt.

"Sister Liu has practiced!"

Liu Yufei glanced at Da Zhao, and then looked at Wang Wenjing.

"Don't spill here, there's no hard evidence to get you? Your daughter and Chen Chunxi have already explained, think about what to say for a while, take it away! ”

With a wave of his hand, several criminal policemen directly pushed Wang Wenjing into the office, after all, the interrogation room was occupied by Chen Chunxi.

Only then did Liu Yufei turn sideways and smile slightly at Zhou Ning and Da Zhao.

"Go to the office next door, Team Xu will come over immediately, Chen Chunxi interrogated all night last night, and this person didn't say a word."

Zhou Ning nodded, Da Zhao followed Zhou Ning and went to Xu Dayuan's office next door, and after a while, Xu Dayuan came in leisurely, holding a packing box with buns in his hand, eating them one by one, and motioned to the two to sit down.

Gobbling it up, he poured another bottle of water, and then he beat his chest and looked at the hands of the two.

"Hurry up and tell me what the test results are."

Zhou Ning was used to Xu Dayuan's urging, and directly put the report in front of Xu Dayuan.

"In the home of the deceased Zhang Guanglei, two bottles of Chinese medicine capsules filled by himself were found, and it was found that 'Dalong' was the kind of anticoagulant rodenticide, which was completely consistent with the residual poison components in the deceased's body, Wang Wenjing's fingernails, and Wang Wenjing's blood.

It can be determined that Zhang Guanglei was poisoned by Wang Wenjing for a long time, and there is also an unexpected gain, the blood stains on Chen Chunxi's car are Sun Manqing's, and the white paint that scratches the traces is consistent with Sun Manqing's Wrangler, and it seems that Sun Manqing's death also had his involvement. ”

Xu Dayuan slapped his thigh, raised his red eyes, and hummed twice in satisfaction.

"Okay, now the chain of evidence is complete, Wang Wenjing poisoned Zhang Guanglei, but although Zhang Guanglei was poisoned and did not die for a long time, he saw him seeing a doctor everywhere, for fear of arousing suspicion, so he planned this car accident with Chen Chunxi.

Wang Wenjing injured his leg, but he just created an alibi for Chen Chunxi, and asked Wang Mengmeng to lead Sun Yannian to the scene, hoping to lead the suspicion to him, after all, his father still has such a relationship with Zhang Guanglei. ”

Zhou Ning also recognized this analysis, looking at Xu Dayuan, who was excited, Zhou Ning asked tentatively:

"Chen Chunxi has been recruited?"

Xu Dayuan glanced blankly and poured another glass of water.

"Recruited? Can I make it look like a red-eyed rabbit? This thing is killed just don't speak, we took turns all night, and we didn't pry open our mouths, so I asked Liu Yufei to bring Wang Wenjing early in the morning, but I didn't expect your test to come out, it's really timely rain, do you want to listen to the interrogation? ”

Zhou Ning looked at Xu Dayuan, who was full of expectation, and could only bow slightly, at this time, if he said that I wanted to sleep, Xu Dayuan could blow his hair, think about it, forget it, after all, he is always so decent.

"Yes."

Sure enough, Xu Dayuan smiled with satisfaction, grabbed the shoulders of the two, and directly dragged the two into the next office.

Wang Wenjing was handcuffed and fixed in a wheelchair.

Da Zhao held the law enforcement recorder, Xu Dayuan, Liu Yufei and a clerk sat on one side, and Zhou Ning stood next to Da Zhao.

Holding hands together, pursing their lips tightly, there was no nervous incoherent speech, but she couldn't help coughing a few times, and when she raised her hand to wipe her nose, there was a nosebleed that didn't come out.

From Wang Mengmeng to Chen Chunxi, and then to this Wang Wenjing, the three participants all showed a similar state, that is, they completely anticipated the situations they might encounter, and even conducted rehearsals.

And the woman in front of her seems to be weak, she may be the real manipulator.

Zhou Ning bent down, opened the investigation box, and took out a physical evidence bag, which contained Wang Wenjing's nails, and then sent it to Xu Dayuan, Wang Wenjing's head did not move, but her eyes kept following Zhou Ning's movements, obviously she knew what it was just at a glance.

Xu Dayuan picked up the physical evidence bag and shook it, and then walked to Wang Wenjing with two of the inspection reports.

"You are very smart, the 'Dalong' rodenticide you chose is a sustained-release agent, and its poisoning reaction generally takes effect after six or seven days of eating, I think you have checked a lot of information, right?

However, after all, you don't read much, and you don't do this profession, you only know one thing but you don't know the other, and you don't even wear gloves when you dispense poison, so let's comrade forensic medicine to give you a popular science and introduce the characteristics of this poison. ”

Wang Wenjing listened to what Xu Dayuan said, her eyes kept blinking, and her eyes were chasing the report, which was a sign of extreme nervousness, Zhou Ning squinted her eyes slightly, maybe what she guessed had happened?
