After 100,000 simulated crimes, I became an ace detective.

An Quan’s words.

It immediately attracted the attention of several people present.

Liu Yang even showed an expression of excitement and surprise. He quickly stepped forward to hold An Quan's shoulder with one hand and put the other hand on the table, and immediately asked excitedly.

"Officer An, have you found it?"

"It's really what Team Leader Su said. This member of the drug trafficking organization whose code name is Poison is probably the cleaner of Vanke Yuncheng Building?"

"Well, I should have found it." An Quan nodded in response seriously, then pointed to the resume on the screen and continued.

"The suspect - Zhong Jianqiang, an 18th-grade pharmacy graduate from Suzhou Medical College, has the ability to extract potassium cyanide from plants, fruits or other chemicals."

"The key is......"

"Due to his personality problems, Zhong Jianqiang repeatedly encountered obstacles during interviews and was unable to work in major pharmaceutical companies or hospitals."

"In the end, because my family's finances did not allow it, I had to temporarily work as a cleaner in Vanke Yuncheng Building."

"When the potassium chloride poisoning case in the private theater occurred, Zhong Jianqiang had already been working as a cleaner in the building for more than half a year. He already had enough conditions to successfully commit murder."

“Also in the records of personnel transfers.

"One month after the incident, the controversy over the murder gradually subsided, and when some people resigned due to work reasons, Zhong Jianqiang also took the opportunity to resign and leave Vanke Yuncheng Building."

Bai Yu also stepped forward at this time, looked at the personal file on the computer screen, and narrowed his eyes.

"Pharmacy graduate?"

"It seems that Zhong Jianqiang can basically be identified. A potassium cyanide poisoning case occurred. After various inferences, the building's cleaners are among the most suspected people."

"It turns out that among the suspicious people, there happened to be a graduate who had graduated from pharmacy but had no ambitions. There is no need to say more about the probability of being absorbed into a drug trafficking organization and committing a murder."

"Brother Quan also mentioned just now that Zhong Jianqiang had been working as a building cleaner for more than half a year before committing the crime, so he can fully understand the blind spots of each surveillance."

"As a result, the surveillance of the building was undoubtedly useless to him, so we did not find any problems during the surveillance."

"And have you noticed..."

"Zhong Jianqiang's family economic conditions are also not good, and the deceased's family conditions are also not good."

"According to most of the crime-solving works I have seen, when carrying out premeditated murders, the probability of choosing people with the same social and economic conditions is not low."

"Because in the eyes of those murderers, the same social status means understanding and better ability to commit crimes."

"Based on Dr. Lan's previous criminal psychology inferences."

"Poison will change his personality and state according to the current surrounding environment. So before he has successfully killed someone and passed the test, Poison will definitely be timid and cowardly."

"Then choosing someone of the same type as yourself to assassinate would naturally be a subconscious choice."

"Because he knows very well..."

"The character of a person like the deceased is as timid and cowardly as him. Even if there is a needle on the chair, he will not pursue it and he does not want to stalemate the relationship with his colleagues."

"And when there are dinner parties, even if I have stomach problems, I will definitely not postpone the meal in order to improve my subsequent work performance."

"And what I think is the most important thing."

"He felt that the deceased had no background, let alone any connections. Even if he died, no one would investigate further. In the end, it would just be an investigation for a while."

This last sentence.

Liu Yang felt unspeakably ashamed and embarrassed.

because.

After this case occurred, the Xiangcheng Criminal Investigation Brigade conducted an exhaustive investigation for several months. However, as a breakthrough was never found, other work was relatively busy.

We can only put it aside for the time being and continue to pursue it when we have time as an unsolved case.

In general.

Indeed, it can only be regarded as an investigation for a while, but the criminal investigation teams in other cities basically operate in the same way.

Zheng Hui also thought of a certain detail at this time, suddenly clapped his hands and said.

"Right, one more thing."

"When we were chatting just now, the deceased's colleagues in the same department mentioned that the reason why he chose that Hunan cuisine restaurant was..."

“That Hunan cuisine restaurant just opened, you just need to get the flyer and you can get a [-]% discount!”

"And I found that every department of Kingway Software will hang a small blackboard to write down each team's work goals and specific time schedule."

"But for example: dinners, annual meetings, holidays, etc., notifications will also be written on the blackboard."

"I think it is very possible that Poison, that is, Zhong Jianqiang, probably saw the flyer and the work schedule on the department blackboard, and learned about the dinner time."

"That's why we were able to replace the original stomach medicine with highly toxic potassium cyanide so accurately."

"Whether it's the obvious details of the crime or the conclusions we've drawn, it feels like we've been able to match up with this Zhong Jianqiang."

this moment.

Liu Yang could no longer suppress his excitement and anxiety and quickly continued to ask.

"Officer An."

"Can you please check specifically where the almost clear suspect Zhong Jianqiang currently works?"

"Or......"

"Where is it hidden in Gusu City? Can you find out in detail?"

Liu Yang hasn't finished speaking yet.

An Quan's hands continued to tap on the keyboard, preparing to go through the internal household registration system and hotel registration system, hoping to find the latest traces of poison.

But three seconds after logging into the household registration system.

An Quan was stunned immediately, adjusted his glasses in disbelief, looked at the logout prompt on the screen interface, frowned and said in surprise.

"Huh? Dead."

"According to our police's internal household registration information, Zhong Jianqiang died in a serious car accident two years ago. His body has been claimed by his family and was burned in a funeral parlor?"

The voice just fell.

Liu Yang immediately leaned forward in disbelief, but when he saw the conspicuous logout prompt, he couldn't help but froze.

But the next second, he immediately shook his head and said firmly.

"Impossible, this is absolutely false."

"In the past two years, we have still found high-purity drugs in our jurisdiction several times, which shows that the poisons are still in Suzhou City."

"Obviously to prevent discovery, the original identity at the time of committing the crime was cut off."

"After all, no matter how you try to cover up the clues, it is better to cancel the original identity with death and cut off the police's subsequent investigation!"

An Quan nodded in agreement, adjusted his black-rimmed glasses habitually, and said slowly and calmly.

"Fake, it must be fake."

"Erase the identity you had when you committed the murder and start a new life with a new identity. For such a huge drug trafficking organization, it is not difficult to complete."

"It can more effectively interrupt the clues we are pursuing, which can be regarded as a good method of hiding crimes."

"Then there's one more thing I want to say."

"If nothing else happens, the leader of the drug trafficking organization who is good at computer hacking technology should also find out that we have found the original identity of the poison..."
