"Isn't this simple? From the monitoring, his age, height and weight are easy to distinguish.
The old dog can install explosives in my car, it means that his education is not lower than high school, otherwise these things will be difficult for him.
Those who can come to rob must have no proper profession. Based on Zhu Qi's confession, we can infer that he has a history of drug abuse. Also, from this perspective, his parents should be farmers, and the family conditions are not good. "
Xu Jiuyan nodded and said, "Yeah, but your reaction is too fast, right?"
"That is, when will the murderer be caught if the reaction is slow?"
Guan Zheng smiled and said, "Did you bring drawing paper?"
"Bring it, why?"
"Is the portrait of the old dog painted?"
"It's painted, here it is!"
Guan Zheng glanced at the portrait and said, "It's pretty awesome, but it's only a seven-point image."
"You haven't seen it again, how do you know?"
"Then we'll take a gamble."
"What are you betting on?"
"If I win, you must promise me one thing. If you win, I will leave the position of the detective captain to you."
"OK!"
Guan Zheng looked at Xu Jiuyan's proud face and smiled slightly.
It took nearly three hours for the car to reach Yujiang County. Xu Jiuyan looked at this small town and said, "I only have a rough location in the village, should I go to the town public security bureau?"
"No, we should be able to find it. It would be very troublesome to go to the Municipal Public Security Bureau. I hate writing all kinds of reports."
Xu Jiuyan nodded and said, "Well, Sand Castle Village, here."
The two rushed to Sandcastle Village along the small road in the town. Xu Jiuyan looked around and said, "Actually, it's still very prosperous. It's not bad to live here when you are old!"
Guan Zheng put Xu Jiuyan's hand in his hand and said, "Don't wander around!"
"Oh, what kind of person is the old dog?"
"Aren't you all portraits? Believe in yourself."
"Didn't you say that there is only a seven-point image?"
"What's wrong with the seven-point image? The seven-point image can play a vital role!"
Xu Jiuyan was dragged by Guan Zheng and arrived at Sandcastle Village in a short while. Guan Zheng stopped an uncle carrying water and asked, "Do you know where Chen Guoqiang is?"
"Guoqiang? Are you looking for him?"
"Well, we are looking for him in a hurry."
"Then you probably won't find it anymore."
"why?"
"Because people are already dead!"
Xu Jiuyan and Guan Zheng were very surprised in an instant. Are they dead? !
Guan Zheng quickly asked: "When did it happen?"
"This morning, he died in his house, and the police are still there!"
Guan Zheng and Xu Jiuyan rushed over immediately.
Guan Zheng and Xu Jiuyan rushed there, and the familiar yellow cordon made Guan Zheng and Xu Jiuyan's heart tense. If such an important witness is dead, then who can testify
As the biggest boss, Lei must not be easily caught by the police. It is almost impossible for such a person to join the Internet and be successfully appealed.
After showing his certificate, Guan Zheng said: "Hello, we are from Nanyi City Criminal Police Brigade, come to Chen Guoqiang."
After checking the ID, the police officer said, "Please come in."
Guan Zheng walked in and saw Chen Guoqiang lying in his corpse. There was no blood on his body, only a pile of white vomit beside him.
Guan Zheng walked into the back room. A police officer wearing white gloves stood up and said, "Who let you in? Get out!"
Guan Zheng threw the certificate over and said: "Guan Zheng, the captain of the Criminal Police Brigade of Nanyi City Public Security Bureau."
"Guanzheng? Criminal psychology expert Guanzheng?"
The police officer said excitedly, "Hello, I am Zhang Liangxi, I have admired you for a long time!"
Guan Zheng smiled and said: "It's okay, don't worry, let this matter go first, I want to know about Chen Guoqiang."
"He, he is a little bastard here. He hasn't come back for many years. He came back suddenly this year, and no one knows why.
Both his parents died early, only one sister, who is also married, but still lives in the village.
According to our understanding, he took a lot of money when he came back this time, and even his family did not know where the money came from. We also doubt the legitimacy of this money. "
Guan Zheng nodded and said: "We are investigating a gold theft case. We suspect that Chen Guoqiang was involved in this case. And we suspect that he is a drug-related person, so I hope to accept this case and the relevant procedures will be completed as soon as possible."
Zhang Liangxi looked admiring and said: "No problem, I will actively cooperate."
"I also need one of your forensic doctors, as well as related materials and equipment."
Zhang Liangxi said: "We have forensic doctors, but he has just been transferred from the veterinary hospital, so I can't guarantee it. As for the equipment, they are all aging and it is difficult to provide technical support."
Guan Zheng frowned and said to Xu Jiuyan: "Call back to the bureau and ask Xiao Juan'er and Li Chongyang to bring related equipment and get here as soon as possible."
"Okay, I'll go right away."
Guan Zheng squatted down, smelled the pile of vomit, and said: "There is no taste of bitter almonds, it is not cyanide, it should be organic poisoning, and crocaine poisoning is initially suspected."
"There are no obvious scars on the body, it should be an acquaintance who committed the crime. The cigarette butts here are two types of cigarettes, indicating that two or more people have stayed here, DNA inspection, to see if there is a criminal record.
You see, there are dragging traces here. It is the traces of someone dragging from behind and the toes left on the ground, which can even more show that there is a second person present.
And it must be a murderer, because if it is a conspiracy, the body can be lifted up without leaving traces of drag. "
Zhang Liangxi nodded and said, "Okay, I'll let someone do it right away."
Guan Zheng looked at the food on the table and said: "The degree of turbidity in the eyeballs is not very deep, and the time of death should have been last night. Judging from the pinhole in the vein of the left arm of the corpse, the risk of death by intravenous injection is still relatively high.
But these foods are all likely to cause poisoning. The same test is not lost, the sooner the better. "
Xu Jiuyan handed over a piece of paper and said, "Guanzheng, look at this."
Zhang Liangxi: "Suicide note? Suicide?"
"The suicide note is fake. Check if there is any dna on the paper. Just check the dna."
Zhang Liangxi also asked with a look of confusion: "How can this be fake?"
Xu Jiuyan looked at the suicide note and explained: "That's the case. The suicide note is a written will, which refers to a document formed by precharging and entrusting future generations on relevant matters before life.
Since the suicide note has the function of reflecting the will and opinions of the deceased, such as explaining the cause of death, the distribution of the inheritance, etc., such documents are often the object of forgery by criminals. "(End of this chapter)
