Mystery Case Tracing [Criminal Investigation]

Chapter 74 Search evidence

Qi Chuchen, who had gotten up early in the morning to wait for orders, answered the phone, found something to fill his stomach decisively, and then went back to bed and went back to sleep. Before going upstairs, he said to Yan Mu, don’t call him if the building collapses, just make up his sleep. Once the quilt was wrapped, Zhou Gong went to Zhougong.

In the afternoon, Yan Mu did not call him, but in the evening, when he was harassed by his hands, they awoke and the two people rolled around again.

Rolling up the quilt again, Qi Chuchen, who was about to meet Zhou Gong, curled up in Yan Mu’s arms. Before he fell asleep, he spit out a few words: missteps due to lust! !

When he went to work the next day, Zhang Chao pulled several people into the small conference room and told them that the pile of things Li Ang had brought back had not been inspected yet, and an abnormal item was found during the inspection. Among the piles of bottles and cans Qi Chuchen collected from the dressing table, there was something disguised as loose powder in a loose powder box. It was not cosmetics, but could be synthetic chemical preparations or medicines. The whole thing has been sent for inspection for specific component analysis, and the results should be available in these two days. That thing is obviously Sun Mengmeng’s, so they are now going to focus on Sun Mengmeng.

As for the other items that have been tested, there is nothing unusual.

In the end, the same sentence means that if this matter really involves criminality, it must be kept low-key. That is to say, everyone should do things with the enthusiasm for major cases, deal with the case secretly with the attitude of taking private work, and repeatedly reiterate to do a good job of confidentiality of information.

Information confidentiality is easy to say, which means that the resources and manpower available to them are limited. All investigations and tests must be handled by as few people as possible. Qi Chuchen remembered that the few big bags that the hotel had brought down that day, inexplicably ordered three waxes to Li Ang in his heart.

Because of the low-key handling, so many things do not need to work overtime to complete. Everyone got off work punctually, Wu Boyan’s sense of taste still did not recover, and he did a lot of checks later in the hospital. Qi Chuchen went to get another report, and the conclusion remained the same for thousands of years: No abnormality was seen.

Before things were determined, Boyan Wu simply stayed in the hospital with peace of mind. Infuse nutrient solutions and vitamins every day to minimize food intake. Drink all bottled water, and double-check before opening the bottle to make sure it is correct.

“Is he so sure that he was poisoned?” Qi Chuchen opened up a bunch of inspection reports of Wu Boyan again, Gao Rui followed by and muttered dissatisfiedly.

Qi Chuchen took a meal and said thoughtfully: “Maybe rich people are Jingui, who knows.”

“Why does he stay in a hotel? Doesn’t he have a fixed residence?” Gao Rui really couldn’t get a good impression of Wu Boyan, and the questions he asked were all kinds of gossip and dissatisfaction.

Zhu Zhen was passing by with the brewed coffee, leaning over and whispering: “I have checked, he has not bought any homes in China. Every city runs around, so there are long private rooms in star-rated hotels everywhere. His home purchases are all overseas. , A lot of assets.”

“Isn’t it expensive to stay in a hotel?” Luo Hao saw the three people get together, thinking that they were discussing the case, and hurried over.

“New type of cooperation, exchange of resources. For example, you went to the Romont Roland Hotel that day. He was a senior consultant, and he was a symbolic salary. The hotel provided him with long private rooms and he attended some hotel activities. A certain number of times a year to help the hotel test New products, adjust the catering layout. I guess he and other hotels are also in this form.” Zhu Zhen said.

Several people were still whispering and saw Li Ang showing up at the door of the office with a pile of things, glanced at them, and walked directly into Zhang Chao’s office.

Several people hurriedly returned to their respective positions and began to sort out the information. As expected, Zhang Chao and Li Ang walked out, Zhang Chao rushed to the door and shook their heads, and several people followed out tacitly.

In the small conference room, all the shutters were closed, Gao Rui walked and finally locked the door. Li Ang handed out a copy of the report copied in his hand.

The white powdery substance in the loose powder box is composed of a variety of medicines and chemical powders. The report lists a bunch of drug names and powder names. The adverse reactions of these drugs can cause taste deterioration. The role of chemical powders can also interfere with taste.

The remaining liquid in the empty milk bottle in the trash can and the half bottle of red wine brought back were all detected with residues similar to the powder in the loose powder box. Other items brought back except for the first time are normal. The fingerprints on the loose powder box are only those of Sun Mengmeng. Fingerprints on other items are more complicated, some of them are Sun Mengmeng, some are Wu Boyan, and some belong to room service staff.

“Only people close to the body can do it,” Luo Hao said.

Zhang Chao looked at the following table, “Chu Chen, let’s go to the hospital to find Wu Boyan about his diet and daily life. You guys are digging up Sun Mengmeng’s situation. Li Ang, you can look at these adverse reactions and need How did it happen?”

“Okay, I will find my pharmacological buddy to study it in detail.”

Qi Chuchen grabbed Li Ang, who was about to go out, “Don’t run out of that powder, save me some.”

Li Ang patted Qi Chuchen’s hand and motioned to know.

Qi Chuchen walked into the ward, Wu Boyan leaned on the sofa to greet them. Seeing the sitting man still stunned. I haven’t seen him for two days. Although this person is not thin, his face is not pale, his voice is not weak, but there is a sign of decay inexplicably.

So it is still: Is it iron rice or steel? ?

Sun Mengmeng was not there at the moment, and Wu Boyan must have sent her out. There were a few bodyguards guarding outside, and Zhang Chao was also straightforward, asking Wu Boyan to introduce his diet and daily life, regardless of the details.

Wu Boyan’s fixed three meals a day are delivered by the hotel except for breakfast, and there is no special requirement. The milk, bread, and butter for breakfast are purchased and stored in the refrigerator. The other two meals are randomly selected from the first batch of freshly prepared meals at the hotel.

Trying new products is very random, and it is not an appointment and notification in advance, and the hotel producer does not know who will try it.

Except as a last resort for socializing and socializing, I don’t usually drink alcohol. Fruit snacks are purchased by themselves.

The guest room is cleaned by special personnel, and the clothes are usually sent to the wife for dry cleaning.

“Who drank the red wine in your room?” Qi Chuchen asked.

“My wife has the habit of drinking red wine before going to bed. The wine she drinks is delivered directly from well-known wineries.” Wu Boyan replied.

“Who handles breakfast? Toast, butter, and hot milk?” Qi Chuchen asked.

“Sometimes it’s my wife, sometimes it’s the room attendant, not necessarily.” Wu Boyan replied.

“Who handled it that morning?” Zhang Chao asked.

Boyan Wu thought about it and spread his hands, “I really didn’t pay attention to this.” After saying this, Boyan Wu reacted and asked, “Is there a problem with the breakfast that day?”

“It’s not determined yet. Because that was the last food you ate before you discovered the abnormality, so we asked more carefully. We are still investigating the rest. Your wife has been following you everywhere, no other work?” Zhang Chao again A question was thrown.

“She is my secretary, responsible for helping me handle all the external contacts and arranging my team work.” Wu Boyan replied.

“I heard that you usually don’t eat green onion, ginger, and garlic. How can you ensure that there is no such thing in the hotel’s dinner?” Qi Chuchen asked a question that seemed to be irrelevant.

Boyan Wu hesitated: “It’s not that I don’t eat it at all. This kind of food will still have a stimulating taste, and it will easily interfere with the taste after relying on habit. I usually choose western dishes for the meals in the hotel, which can basically avoid this problem. I want to eat Chinese food. For a change of taste, my wife will basically make it herself, so just leave it alone.”

“How are you feeling today” Zhang Chao asked.

“The sense of taste still hasn’t recovered.” Mentioned this, Wu Boyan looked sad.

The two asked more casually, and left the ward. Zhang Chao called Li Ang and learned that Li Ang had sent the sample to his buddy who was studying pharmacology, and it took at least three days for the results to come out.

Since the result needs to be waited, it is natural to commute to and from get off work normally.

Three days later, Li Ang relayed his buddy’s test results. Because this test is not in the scope of scientific research and does not conform to their research process, it is purely the private work of Li Ang. Moreover, some methods used in this analysis and testing, some methods of researching data are all summed up by Li Ang based on his own experience, and neither public nor private can submit reports on paper. But Li Ang repeatedly stated that the results are absolutely credible.

“Dude? Your boyfriend?” Qi Chuchen said directly after listening to Li Ang’s foreshadowing.

Li Ang’s face turned red at once, and a few people in the small conference room burst into laughter at a glance.

“It has nothing to do with the accuracy of the results, okay.” Li Ang whispered.

“Then you said that you want to chase me that day and change your mind when you see a difference!” Qi Chuchen continued.

…………

After the joke, Li Ang unfolded his notebook and began to summarize the handwritten notes of his famous buddies during the test. There are several chemical powders that are not easy to find, and the ratio of these types is also exquisite. In addition to reducing the pungent taste in the smell, the taste will be reduced after the taste is integrated. It dissolves more quickly, whether it is hot water, warm water, or ice water can fully dissolve. After blending, it can ensure that the side effect of taste degradation in the drug is intensified to the maximum.

In theory, taking no less than 1 gram per day, at least for more than one month, will gradually degrade the taste. Continue to take it for a period of time to ensure that the taste disappears. Whether the follow-up is reversible or not depends on the individual user. It is not clear if there is no test sample.

“Sure it can cause the loss of taste?” Zhang Chao asked.

“This is theoretical data. After all, this kind of thing is impossible for us to be clinically tested. This is theoretical data that has been rigorously deduced.” Li Ang replied.

“If you want to shorten the onset time, do you have to increase the dose?” Qi Chuchen asked.

“Yes, the amount of 1 gram is probably the amount that is not easy for ordinary people to detect the peculiar smell. If you want to lower the peculiar smell, you have to reduce the amount and increase the time.”

“If you only take it for two or three days, is there any effect?” Qi Chuchen asked.

“Basically there is no effect. It’s almost like eating a few meals and putting too much salt.” Li Ang replied after taking a look at the notes.

A momentary blank appeared in the conference room, and everyone was looking at the key words they had recorded.
