in the dawn

Looking at the faint morning light on the horizon in the distance, Qiao Yuchuan raised his hand, then slowly put it down, gathered his clothes, and walked towards the office building.

Seeing Qiao Yuchuan walk into the office, Jiang Chengyun got up and poured a glass of warm water, then sat beside him, "Is it better?"

Qiao Yuchuan stared blankly at Jiang Chengyun for a while, then nodded, "How's the situation?"

"Currently, before Feng Zhen died, there were three people who had direct contact with him."

"First of all, Liu Hao. He went in to deliver water once. The water was a complete bottle of water. After investigation, no pinholes or the like were found. The water in the bottle has been sent for inspection."

"The second person to go in is Zhao Bin. He is a newcomer to the Beihe Detachment not long ago. The dinner he sent in was made in the unit cafeteria. Most of the people on duty tonight ate it. Samples have been taken and sent for inspection. gone."

"The last person was Tan Qing. He handed Feng Zhen a cigarette, which was his personal cigarette." Jiang Chengyun said that Tan Qing's eyes were obviously darker.

"Smoke?" Qiao Yuchuan frowned?

"What is the origin of this Tan Qing? When did he join the detachment."

Jiang Chengyun narrowed his eyes, "I asked the guard just now, and he said that Tan Qing was only transferred to the detachment in the last six months, and he has always performed very well. His hometown is Beihe."

"And according to Tan Qing, it was Feng Zhen's request that he give Feng Zhen the cigarette. He gave Feng Zhen one of the cigarettes he usually smokes. The cigarette Feng Zhen smoked has already been investigated, and the rest The smoke has also been sent for inspection."

"Give Tan Qing and the others a checkup."

"Are you suspicious?"

Qiao Yuchuan shook his head slightly, "I don't suspect anything, I'm just considering various possibilities."

Jiang Chengyun thought about it and got up and went out to make arrangements. Zhao Xiaohe stood outside the office door and saw Jiang Chengyun leaving, so he walked in slowly and stood opposite Qiao Yuchuan.

Qiao Yuchuan looked up and saw Zhao Xiaohe took out a lollipop from his pocket, "You don't look well, this is for you."

Qiao Yuchuan lowered his eyes, and Zhao Xiaohe saw that he didn't answer, so he put the candy on the table beside him, "What I said just now is just the truth, and it's not aimed at you."

Qiao Yuchuan stared at him, "Zhao Fayi, do you think that as a professor of psychology, I have spent so many years researching in vain."

When Zhao Xiaohe heard this, he turned around and left. Qiao Yuchuan turned his head to look at the lollipop on the table, and picked it up. Before he could study and understand what it tasted like, Jiang Chengyun took it.

"Why do I remember eating a lollipop? Who gave it to me? It still tastes like grapes." Jiang Chengyun asked with raised eyebrows.

"Forensic Zhao."

Hearing these three words, Jiang Chengyun was stunned, and returned the lollipop to Qiao Yuchuan, "Eat it if you want."

Qiao Yuchuan glanced at Jiang Chengyun, then slowly tore open the package, "Did he not tell you anything?"

Jiang Chengyun leaned back, put one arm on Qiao Yuchuan's shoulder, with a lazy expression, "He said, you like me."

Qiao Yuchuan frowned, and put the lollipop into his mouth. The sweet taste spread quickly in the mouth. Sure enough, sweet things will make people feel happy.

Jiang Chengyun's gaze stayed on Qiao Yuchuan's half-length hair. Just now, he contacted the expert in charge of the inspection and heard a lot of information about "Landiao" from the other party.

"The harm of this drug to the human body is not obvious in small doses, but once the dangerous dose is exceeded, the degree of harm to the human body is inestimable, and the damage is irreversible."

"What you said, the increased sensitivity, mental agitation and confusion, these are all obvious external effects. I suspect that this drug may have other side effects."

"If your lover has been exposed to this kind of drug, you should pay more attention to his daily activities and try to avoid him from being exposed to this kind of drug or something similar to drugs. After all, the existing conditions are still unable to judge the similar function. Things, whether it will affect him."

One message after another made Jiang Chengyun's eyes gradually darken. He reached out and stroked Qiao Yuchuan's hair. He stood by the pillar outside the gate of the detachment for a long time, and he also saw the situation inside the car to some extent.

But it was precisely because he saw it that he felt more distressed and saddened. What happened to the people he put in his heart had made him used to hiding his emotions and thoughts, and even his pain.

Qiao Yuchuan felt the hand stroking his hair pause slightly, so he turned his head and saw that the other person looked back inexplicably, Jiang Chengyun slightly curled his lips.

Soon, the investigation results came out. No blue tone was detected in the cigarette Tan Qing handed to Feng Zhen, and no blue tone was detected in the remaining smoke, including Tan Qing himself.

Similarly, no abnormalities were found in the food and water, and no blue tone was detected in Liu Hao and Zhao Bin's bodies.

It can be said that this result made everyone breathe a sigh of relief, but at the same time they were all lost in thought. If it was not detected, how did Feng Zhen die, and what happened to the high concentration of blue tones in Feng Zhen's body.

Director Wu handed the report to Jiang Chengyun, and then he looked at Qiao Yuchuan, "Professor Qiao, what do you think, can you say it now?"

Qiao Yuchuan's brows and eyes moved slightly, and he exhaled gently, "Feng Zhen's death gave me a reminder. The report shows that there is a high concentration of blue tones remaining in Feng Zhen's body."

"At first, I also thought that someone had added a high concentration of blue tunes to the things Feng Zhen had touched through drugging, which led to his sudden death, but the results now confirm a conjecture I had long ago. "

"What guess?" Wu Chengkun asked.

Qiao Yuchuan took a deep breath, and his face became serious, "After entering the human body, the blue tune should be difficult to be metabolized. Over time, it will gradually accumulate in the human body and cause damage to the human body, and it is irreversible. "

"I guess, Feng Zhen should have used a lot of blue tunes long ago, and his body has reached a critical point. We arrested him, questioned and examined him, and only catalyzed his death process invisibly."

"You mean, chronic poisoning?" Zhao Xiaohe asked in a deep voice.

Qiao Yuchuan nodded, "It's understandable, but it's not quite right."

"The blue tone itself is not weak, even higher than ordinary drugs. It should be because of this characteristic that it has not been completely abandoned."

"Of course, I am also guessing and skeptical. After all, there is no experimental or theoretical support."

Qiao Yuchuan's words made everyone fall into deep thought. The matter has developed to this day, and they are still confused, as if everything is hidden in the mist, and they are searching hard but can't find the direction.

Wu Chengkun's face was dark and serious, and he took a while to speak, "I just went through the record of the interview with Feng Zhen again, and there are many suspicious points in it, Jiang Chengyun, tell me what you think."

Hearing this, Jiang Chengyun turned over the information at hand, "I think everyone should have read the inquiry record carefully, and I have summarized a few points from it, let's discuss it together."

"First of all, there are still doubts about whether the person caught is Feng Zhen."

"Let's assume that he is Feng Zhen first, then from the dialogue and situation analysis, we can draw four major doubts."

Jiang Chengyun's face was serious, "First, I have carefully reviewed the case back then. Feng Zhen was a man with skilled, cruel methods and strong anti-investigation awareness. Fingerprints and things that can authenticate records."

"And a person like him was able to hide his whereabouts so well during the past seven years that we couldn't find any traces at all. Why was he bumped into or even captured so easily?"

"Secondly, this person said he was Feng Zhen. He hated Zheng Chuyuan and wanted to kill him, but in fact, the person who stabbed Captain Zheng had a very obvious tear mole on his face. Maybe this tear mole is It’s fake, but no matter it’s true or not, I should know about it, but he has repeatedly emphasized that he doesn’t know about the tear mole.”

"Thirdly, he has always emphasized that he will admit it or not, but it is not difficult to see from his statement that he can't explain many things clearly. Moreover, if it is really Feng Zhen, he will not admit it when he finds out. Will you choose to take the risk and come back after there are corpses in this room?"

"Fourth, in the case back then, some psychologists analyzed Feng Zhen's behavior and concluded that he had resistance and hostility towards women. Such a person would have sex with Mo Nan today, seven years later. Is such a woman friendly? Even if she was deceived, she didn't want to kill her, and even believed her."

The four doubts listed by Jiang Chengyun silenced everyone. According to this calculation, the person they arrested was probably not Feng Zhen, but who would it be if it wasn't him, and why would this person admit it.

"If we assume that he is not Feng Zhen, then I will face the following problems."

"First of all, he is not Feng Zhen, so what he said cannot be taken as evidence at all, and cannot even be easily believed."

"What happened in the Shanghe community, whether Mo Nan was involved in it, who was the person who stabbed Team Zheng, who was the corpse in the refrigerator in the old community in Beihe City, and who killed it? His testimony shall be judged."

After Wu Chengkun listened, he tapped his fingers on the table a few times, "After all, the clues we have at present are limited, and all of them are inferences rather than conclusions."

"The province also attaches great importance to this case. Zhou Yan will go to Beihe City tonight."

"Jiang Chengyun, take the time to sort out the information in your hands. When Zhou Yan comes, hand over to him, and bring your people back to the Hengtian City Bureau. You and Zhou Yan will jointly investigate and concentrate all your efforts to solve the case as soon as possible. "

"Yes."

After the meeting was over, Jiang Chengyun began to arrange manpower to sort out the materials. Qiao Yuchuan stood silently in front of the window, looking at the dark night in the distance. After Jiang Chengyun delivered the materials to Bureau Wu, he took a piece of clothes and walked over.

"What are you thinking about?"

Qiao Yuchuan tilted his head slightly, "I want to go out for a while."
