Chapter 151 Do you want to listen to the interrogation
Zhou Ning looked around for a week and said quietly.

"Dalong is an anticoagulant rodenticide. It is a chronic drug. This type of drug is fat-soluble, so it has no effect when placed in water. It is completely insoluble in water. First, it needs oil, and second, it needs long-term With the effect of time, Zhang Guanglei can keep in touch."

Da Zhao looked around, and found that the man's kitchen was useless, and the seasoning and food were out of the question. He also checked the other items in the room, and found nothing special.

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

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

"There is no special smell. I remember that in the introduction of the poison, it says that it has good palatability. As bait, it is not easy to be rejected. That is to say, it has no special smell. As for the off-white powder."

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

Zhou Ning also walked over there, leaving the aluminum-plastic packaging aside, and found two white bottles without any printed packaging, with Zhang Guanglei 2011.7 and Zhang Guanglei 2011.8 written on them with a marker.

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

Once a day, three capsules at a time, take before going to bed.

Da Zhao compared it, and the July bottle was obviously less than the August bottle, and apart from this, there was no capsule preparation at all in the box.

"Is this Dalong?"

Zhou Ning opened a capsule and fiddled with the powder. In the middle of the herbal powder, there was indeed a finer off-white powder mixed with completely different properties.

"The feeling is that this thing is fat-soluble. If it is sub-packaged and mixed with medicinal powder, and the capsules are filled by yourself, it is easy to remain in the crevices of the nails and cannot be washed off easily. Moreover, if the nails are in contact with them for a long time, there may be some in Wang Wenjing's body. Let’s do a poison test on Wang Wenjing’s blood tomorrow.”

Da Zhao blinked.

"Okay, we won't know the results until everything is tested."

The two evacuated, and sent a message to Xu Da on the way, telling him that some medicine powder suspected to be mixed with Dalong was found here, and 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 and glanced at the table. A report was already on the table, and Da Zhao raised his eyebrows at Zhou Ning.

You praise me all over your face, you praise me!

Zhou Ning couldn't stop laughing. This guy has a really good personality. Working with him will never be affected by some negative emotions. After all, he can make you out of the haze in minutes.

"The test results came out? Didn't you tell Sister Cui yesterday that we won't send you for testing at night, what excuse are you using?"

Big Zhao grinned.

"What are you talking about? Am I that kind of person? We don't need to make excuses, just find the person on duty, take some food from Xu Da's place, and send it over directly, then put the things down, and make a serious statement that we will do poison tomorrow. Analysis, today I have promised with Sister Cui not to send for inspection.

That person became stubborn with me, and argued for a long time, and then the machine was doing the test. We ate two roast ducks and some other food. right.

The poisonous ingredients in the traditional Chinese medicine powder are exactly the same as those found in the body of the deceased and Wang Wenjing's hands. Oh, Wang Wenjing's blood also has a certain amount, but a little less.

There is another test result, which is a bit unbelievable, that is, when Chen Chunxi was scratched on the car, the blood was from Sun Manqing, and the white traces were consistent with Sun Manqing's horseman. The car was hit by a car, and no car was found at the scene. It seems that Chen Chunxi did it. "

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

"Let's go, Xu Da has been tossing all night, I guess we are waiting for this result, let's go over and have a look, by the way, Wang Wenjing and the others brought it?"

Da Zhao shook his head.

"After I tossed about the inspection report, I called Xu Da, but he couldn't get through. He was supposed to be interrogating, so I didn't call again."

As they said that, 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 woman screaming, that kind of crazy roar.

"Ah! Let go of me. I'm a patient, and I can't move my legs. Where are you touching your hands? I want to sue you. What's your police number?"

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

Before Zhou Ning and the others approached, they saw Liu Yufei took two steps towards the run-up and kicked directly at the door. Such a big movement shocked Wang Wenjing who was hugging the door.

Da Zhao shrank his neck, Liu Yufei's action was too tough, far from his usual gentle and quiet appearance.

But after thinking about it, I know that a beautiful woman will never stay in the Criminal Police Force just because of her looks. Just this kick, she feels like she has a black belt.

"Sister Liu has practiced!"

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

"Don't mess around here. There is no conclusive evidence to get you here? Your daughter and Chen Chunxi have already explained it. Think about it for a while and take it away!"

With a wave of their hands, several police officers 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 right away. Last night, Chen Chunxi interrogated him all night. This man didn't say a word."

Zhou Ning nodded, Da Zhao Pidianpidian followed Zhou Ning, went to Xu Dayuan's office next door, Xu Dayuan wandered in for a moment, holding a packing box with steamed stuffed buns in his hand, eating one bite at a time, motioned to the two to sit down .

After wolfing it down, he poured another bottle of water, then he beat his chest and looked into the hands of the two of them.

"Hurry up and tell me what the test result is."

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

"In the home of the deceased Zhang Guanglei, two bottles of Chinese medicine capsules he filled were found, and it was found that 'Dalong' was the anticoagulant rodenticide. unanimous.

It is certain that Zhang Guanglei has been poisoned by Wang Wenjing for a long time, and there is another unexpected harvest. The blood stains on Chen Chunxi's car belonged to Sun Manqing, and the scratched white paint was consistent with Sun Manqing's horseman. It seems that Sun Manqing's death also had his participation. "

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

"Okay, now the chain of evidence is considered complete. Wang Wenjing poisoned Zhang Guanglei, but although Zhang Guanglei was poisoned, he didn't die for a long time, but seeing him go to see a doctor everywhere, he was afraid of arousing suspicion, so he planned the car accident with Chen Chunxi.

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

Zhou Ning also agrees with this analysis. Looking at Xu Dayuan who spoke excitedly, Zhou Ning asked tentatively:

"Chen Chunxi recruited?"

Xu Dayuan rolled his eyes, and poured another glass of water.

"Recruited? Can I act like a red-eyed rabbit? This guy just doesn't talk when he's killed. We took turns on the night without prying his mouth open, so I asked Liu Yufei to bring Wang Wenjing here early in the morning. I didn't expect your The test came out, it's really timely, do you want to listen to the interrogation?"

Zhou Ning looked at Xu Dayuan who was full of anticipation, and could only nod his head slightly. At this time, if he said that I want to sleep, Xu Dayuan would blow his hair, think about it or forget it, after all, he is always so decent.

"think."

Sure enough, Xu Dayuan smiled with satisfaction, took the two of them by the shoulders, and dragged them into the next office. For Wang Wenjing, interrogation with too many people was a kind of 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 sat on one side, and Zhou Ning stood beside Da Zhao. In such a battle, Wang Wenjing lost the sarcasm just now.

She clasped her hands together and pursed her lips tightly. She didn't speak nervously and incoherently, but 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 this Wang Wenjing, these three participants all showed a similar state, that is to say, they had fully anticipated the possible situations they might encounter, and even carried out rehearsals.

And the woman in front of her seemed weak, she might be the real manipulator.

Zhou Ning bent down, opened the investigation box, 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 followed Zhou Ning's movements, obviously she knew it was just a glance. what.

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

"You are very smart. The 'Dalong' rodenticide you chose is a slow-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 don’t study much, and you don’t do this major. You only know one thing and don’t know the other, and you don’t wear gloves when dispensing the poison. Let us forensic comrades do a popular science for you and introduce this poison. characteristic. "

Listening to what Xu Dayuan said, Wang Wenjing kept blinking her eyes, and her eyes were chasing the report. This was an expression of extreme nervousness. Zhou Ning narrowed her eyes slightly, maybe what she guessed had already happened?
