crime profiler in the dark

Seeing that the day was about to pass, when he was about to get off work, Bai Haolin received a call from Yi Yunzhao:

"Doctor Bai, there is something wrong with the deceased!" There was some noise on his side, so he tried to amplify his voice as much as possible: "I heard from his colleagues that he has been complained of theft three times."

"But there is no record of his criminal record in the police station's system." Bai Haolin said.

"Yeah, because every time his uncle, the owner of the property company, came forward to settle the matter." Yi Yunzhao said, "Also, I checked the cleaning staff's work schedule, and they clean the office between 07:30 and 06:30 in the morning. After [-]:[-]pm, other than that, it will only be cleaned if there is an emergency."

"I see, thank you for your hard work." Bai Haolin hung up the phone, Yi Yunzhao's investigation had made him guess seven or eight points.

"What's the matter?" He Guangzhong could tell from Bai Haolin's expression that the call was related to the case.

Bai Haolin briefly talked about Yi Yunzhao's discovery.

"It is very likely that Zhang Huayong was caught stealing something in Luo Yulie's office and they caught him. No, it should be said that he must have seen something he shouldn't have seen, so he was silenced!" He Guangzhong quickly ran to the forensic office after speaking.

Liu Jiajie has already finished the autopsy, and the report has been sent to one place. He was a little unhappy about He Guangzhong's sudden visit:

"Mr. He, the report has been sent to one place."

"I've already read it. But you didn't do DESI!" He Guangzhong's tone was very severe, which made people uncomfortable.Although he did not see this report with his own eyes, from his previous contact with Liu Jiajie, he knew that this person lacked a sense of responsibility, was self-willed, and extremely conceited of his professional skills, so he had already guessed that Liu Jiajie wrote in the report something.

"DESI?" Liu Jiajie snorted out of his nasal cavity, annoyed and a little dazed.

"Ah——! The legendary spray ionization technology!!!" Qin Siye next to him was very excited when he heard this, "I only saw it in Discover, it's very high-tech!!"

"What is it?" Bai Haolin saw that Liu Jiajie didn't know what it was, but he didn't want to ask Qin Siye, who was younger than him, so he asked on his behalf.

"It is to spray water full of electrospray on the fingerprint, dissolve the mixture in the fingerprint, and then put it into the mass spectrometer to identify what the deceased has been in contact with."

He Guangzhong showed an expression of appreciation: "I didn't expect you to understand so much at such a young age!"

"I remember there is a mass spectrometer in the department, let's try it!" Qin Siye excitedly said to Liu Jiajie.

Liu Jiajie was extremely reluctant, he didn't like to listen to the little girl Qin Siye, and he didn't like the fact that she knew more than him.

Although what the deceased touched was not an item, but a document, DESI may not be useful, but try it anyway.

The mass spectrometer of the Baihu Police Station is old-fashioned and runs very slowly. Deng Jun, the inspector of the Hidden Trace Inspection Office, said that it would take three hours to get the results. Bai Haolin suggested that He Guangzhong go back to rest and look at it tomorrow morning. He refused because he was worried that the evidence would be destroyed, so he stayed here because he was worried. Bai Haolin also wanted to know the final result as soon as possible. He ordered some takeaways and waited with He Guangzhong. It happened that Qin Siye was on duty tonight. During the night shift, He Guangzhong invited her to have dinner together.

"Haolin, I just read a report, and it didn't mention that the deceased had stolen. How did you find out?" He Guangzhong asked.

"It was found by Yun Zhao, Yi Yunzhao, a policeman from the Fifth Criminal Investigation Division."

"Oh, he also majored in psychology, right?" He Guangzhong had a good impression of this young police officer who had only met once.

"Pfft." Qin Siye couldn't help laughing, "That guy's observation skills are very strong, but his logical thinking is different from others, for example: if he has ten yuan, you can ask him to borrow five yuan, He will tear it in half for you." She had no ill intentions towards Yi Yunzhao, but when she thought of his extraordinary words, she felt it was funny.

"But his observation skills are really good, and he has a strong sense of justice and responsibility." Bai Haolin defended Yi Yunzhao.

"I heard from Ouyang that you always wanted to be a judge, why did you give up?" He Guangzhong turned around.

"The plan didn't change quickly." Bai Haolin smiled and went over.

"Old He, Old He, tell us about the cases you have handled in the FBI!" Qin Siye clasped his hands together and said expectantly.

"They are all tragic cases, but some cases may help you in your future work."

The three of them were talking, and the time passed very quickly. Before they knew it, the analysis result came out: Zhang Huayong had touched ** and coffee before his death.

Putting drugs and coffee together can cover up the smell and prevent drug dogs from smelling it, which is a common trick used by drug dealers!It seems that Luo Yulie used the import and export company as a cover to actually smuggle drugs. His brother in the Coast Guard must have helped a lot!

The reason why the case has not progressed lies in the motive of the murder. In this way, the truth has surfaced!What happened is likely to be something like this:

Zhang Huayong has a habit of stealing. He took advantage of the fact that the Luo brothers were out at noon, and sneaked in under the pretext of cleaning the office. He originally wanted to find some valuables, but accidentally discovered that they were smuggling drugs, so he was silenced by the Luo brothers who returned halfway!

Taking a step back, even if the Luo brothers cannot be prosecuted for murder, they can still be prosecuted for smuggling and drug trafficking. The case that was originally deadlocked has ushered in a new situation! !

He Guangzhong watched the inspector of the support department lock the inspection report into the filing cabinet before leaving in peace.
