?

Zhou Ning looked around and said quietly.

"Dalong belongs to the anticoagulant type of rodenticide. It is a drug for chronic attacks. These drugs are all fat-soluble, so they have no effect when placed in water. They are completely insoluble in water. Firstly, they need oil, and secondly, they need long-term growth.

The effect of time can keep Zhang Guanglei in contact."

Da Zhao looked around and saw that this man's kitchen was useless. There was no condiments and food left. He also checked other items in the room and found nothing special.

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

"What's special about the color, smell, and taste?"

"It has no special smell. In the introduction to the poison, I remember it said it has good palatability and is not easily rejected as bait. In other words, it has no special smell. As for the powder, it is off-white in color."

Da Zhao paused and turned his head to look at Zhou Ning. He seemed to have thought of something and walked quickly towards the coffee table in the living room. He found a storage box under the coffee table. The huge box was filled with medicine bottles.

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

Opening the bottle, there was no aluminum foil seal inside. There were capsules inside. You could see that there was yellow-brown powder inside, and a piece of paper was stuffed inside. Zhou Ning used tweezers to take it out, and unfolded it to see the printed writing on it.

Take three capsules once a day before going to bed.

Da Zhao made a comparison and found that the bottle in July was obviously less than the bottle in August, and apart from this, there was no capsule preparation at all in the box.

"Is this Dalong?"

Zhou Ning opened a capsule and picked up the powder. Among the herbal powders, there were indeed gray-white and more delicate powders mixed in. The properties were completely different.

"My feeling is that this stuff is fat-soluble. If you pack it and mix it with medicinal powder, and pack the capsules yourself, it will easily remain in the gaps between the nails and cannot be washed off easily. Moreover, if the nails are exposed to it for a long time, Wang Wenjing may also have it in her body.

Regarding the poison ingredients, let’s do a poison test on Wang Wenjing’s blood tomorrow.”

Da Zhao blinked.

"Okay, we will know the results after everything is tested."

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

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

The next day.

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

Your face is full of expressions of you praising me and you praising me!

Zhou Ning couldn't help laughing. This guy has a really good personality. Working with him, you will never 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 would no longer send for tests tonight? What excuse did you use?"

Da Zhao grinned with his teeth.

"What are you talking about? Am I that kind of person? We don't need to make excuses. We just found the person on duty and took some food that Xu Da had brought and sent it directly. Then we put the things down and made a serious statement that we would make poison tomorrow.

Analysis, today I made a promise with Sister Cui not to send it for examination.

The man got angry with me and argued for a long time, and then the machine did the test. We ate two roast ducks and some other food. After eating, the tests were done. The results were already out, and we also did a comparison.

right.

The toxic ingredients in the traditional Chinese medicine powder are exactly the same as those found in the body of the deceased and on Wang Wenjing's hands. Oh, there is also a certain amount in Wang Wenjing's blood, but it's just slightly less.

There is also a test result that is a bit strange. The blood stain where Chen Chunxi was scratched on the car is that of Sun Manqing. The white trace is consistent with Sun Manqing’s Wrangler. I remember during the surveillance, the Wrangler was hit sideways, but I couldn’t see clearly what was hit.

There was a car collision, but no vehicle was found at the scene. It seems that this was done by Chen Chunxi."

Zhou Ning took one look at the result, breathed a sigh of relief, and waved his hand towards Da Zhao.

"Let's go. Xu Da has been struggling all night and is probably just waiting for the result. Let's go over and have a look. Did Wang Wenjing and the others bring them?"

Da Zhao shook his head.

"After I finished fussing with the inspection report, I called Xu Da. He couldn't get through. He was probably interrogating me, so I didn't call again."

With that said, the two of them had arrived at the front building. As soon as they entered the office area of ​​the first team, they heard a burst of women's screams, a kind of crazy roar.

"Ah! Let go of me. I'm a patient. I can't move my legs. Where are you touching your hands? I want to file a complaint against you. What's your alarm number?"

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

Before Zhou Ning and the others could get closer, Liu Yufei took two steps to run and kicked the door directly. Such a big movement startled Wang Wenjing who was holding the door.

Da Zhao shrank his neck. Liu Yufei's actions were too fierce and very different from her usual gentle and quiet demeanor.

However, if you think about it, you will know that a beautiful woman will never stay in the criminal police team just because of her looks. Just this kick, she feels like a black belt.

"Sister Liu has practiced!"

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

"Don't act recklessly here. How can we get you here without conclusive evidence? Your daughter and Chen Chunxi have already confessed. Think carefully about what to say and take them away!"

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

Liu Yufei then turned sideways and smiled slightly at Zhou Ning and Da Zhao.

"Go to the office next door. Team Xu will be here soon. Chen Chunxi interrogated him all night last night, but he didn't say a word."

Zhou Ning nodded, and Zhao Pidianpidian followed Zhou Ning to Xu Dayuan's office next door. Xu Dayuan wandered in after a while, holding a packing box with steamed buns in his hand, eating one bite at a time, and gestured to the two of them to sit down.

.

He wolfed it down, drank another bottle of water, then beat his chest and looked at the hands of the two men.

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

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

"At the home of the deceased Zhang Guanglei, two bottles of traditional Chinese medicine capsules filled by himself were found. In them, it was found that 'Dalong' is an anticoagulant rodenticide that is completely consistent with the residual poisonous ingredients in the deceased's body, Wang Wenjing's fingernails, and Wang Wenjing's blood.

Consistent.

It can be determined that Zhang Guanglei was poisoned by Wang Wenjing for a long time. Another unexpected result is that the blood stains on Chen Chunxi's car belong to Sun Manqing, and the scratch marks on the white paint are consistent with Sun Manqing's Wrangler. It seems that he was also involved in Sun Manqing's death."

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

"Okay, now the chain of evidence is complete. Wang Wenjing poisoned Zhang Guanglei. However, although Zhang Guanglei was poisoned, he did not die. However, seeing him going to see a doctor everywhere, he was afraid of arousing suspicion, so he planned this car accident with Chen Chunxi.

Wang Wenjing injured her own leg just to create an alibi for Chen Chunxi, and asked Wang Mengmeng to lure Sun Yannian to the scene in the hope of drawing suspicion onto him. After all, his father still has a relationship with Zhang Guanglei."

Zhou Ning also agreed with this analysis. Looking at Xu Dayuan who was talking excitedly, Zhou Ning asked tentatively:

"Chen Chunxi recruited?"

Xu Dayuan rolled his eyes and drank another glass of water.

"Here you go? Can I make him look like a red-eyed rabbit? This guy won't speak even if I beat him to death. We took turns all night and didn't even pry his mouth open, so I asked Liu Yufei to bring Wang Wenjing here early in the morning. I didn't expect you.

The test results came out just in time, do you want to hear the interrogation?"

Zhou Ning looked at Xu Dayuan, who was full of expectations, and could only nod slightly. If Xu Dayuan said that I wanted to sleep at this time, Xu Dayuan would be furious. Think about it, forget it. After all, he is always so decent.

"think."

Sure enough, Xu Dayuan smiled with satisfaction, held the two of them by the shoulders, and dragged them directly into the office next door. For Wang Wenjing, interrogation with more people was a pressure on her.

Wang Wenjing was handcuffed and fixed in a wheelchair.

Da Zhao held up the law enforcement recorder, Xu Dayuan, Liu Yufei and a clerk were sitting on one side, and Zhou Ning stood next to Da Zhao. With such a formation, Wang Wenjing lost her playful attitude just now.

She held her hands together, pursed her lips tightly, and was not nervous or incoherent. However, she couldn't help coughing a few times. When she raised her hand to wipe her nose, she didn't notice any nosebleeds.

From Wang Mengmeng to Chen Chunxi to Wang Wenjing, these three participants all showed a similar state. In other words, they had fully anticipated the possible situations they might encounter and even conducted drills.

The woman in front of me seems weak, but she may be the real manipulator.

Zhou Ning bent down, opened the investigation box, and took out an evidence bag, which contained Wang Wenjing's fingernails, and then handed it to Xu Dayuan. Wang Wenjing's head did not move, but her eyes followed Zhou Ning's movements. Apparently she knew it was just a glance.

What.

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

"You are very smart. The 'Dalong' rat poison you chose is a sustained-release agent. Its poisoning reaction usually takes six or seven days to take effect. I think you have checked a lot of information, right?

However, after all, you have little education and are not in this profession. You only know one thing but not the other. You don’t wear gloves when you pack the poison. Let us forensic comrades give you a popular science and introduce the poison.

characteristic."

Wang Wenjing listened to what Xu Dayuan said, her eyes kept blinking, and her eyes were chasing the report. This was a sign of extreme nervousness. Zhou Ning narrowed his eyes slightly, maybe what he guessed had happened?
Chapter completed!
