Police order

Chapter 173
After about half an hour, some simple survey results appeared.

There were at least four people here yesterday, including the deceased, two men and two women.The actual number may be more, but not less.

The cause of death of the deceased was indeed ice poisoning, which had reached more than twice the lethal dose of a normal person.

Ice is actually something special.For example, flour, the difference in tolerance of this thing is not too big for each person, basically the lethal dose is 0.25 grams.But ice is different, the tolerance level of this thing varies from person to person, and the lethal dose can vary by a hundred times.

Some people, the first time they engage in a little bit, they die immediately, not an exaggeration at all.

So many people think that this thing is less harmful than flour, and they really don't know how to write the word "death".

Not only that, no related substances were detected in the hair of the deceased.This means that during the past few months, the deceased has not played these, and this time may really be the first time.This is also in line with You Shaohua's inference.

Although DNA has not been done yet, according to preliminary analysis, the six TTs left at the scene were all used by the deceased alone.

However, the two pots left at the scene were played by two people, and they are currently extracting DNA.

The top priority now is to find the two women who were here last night.

The video surveillance department retrieved the elevator video, hotel video and door video, but has not yet drawn a conclusion.The video footage of the elevator and the entrance is relatively good, there are no blind spots, and everyone who comes in can be seen, but the surveillance on this floor is not good, there are many dead spots, and some surveillance has been out of order for several months.

As for the unmonitored corridors, trace extraction is also more difficult.There are too many tourists, and many of them come with families. The husband dare not smoke in the house, so he runs to smoke in the corridors, so the corridors on each floor are the scene of changes.

Lu Ling and Yan Yu had a long exchange about psychological profiling.

Yan Yu has a lot of theory and knows the method of this thing, but because she is not a related major and has not studied it, her ability is very weak.And Lu Ling has a solid foundation, and after the exchange, he obviously felt that he had found a way.

Profiling is not such a magical thing.For example, when seeing a corpse scene, most people would think that the murderer was a bit perverted, and that there might be problems with family growth when he was a child.

This is also psychological analysis and profiling, but the profiling by psychologists is more professional and magical.

"If the murderer also played, then he would most likely be hyperactive. It is impossible for an hyperactive person to act so calmly, so the murderer did not play, and the murderer just tricked the deceased into playing." Yan Yu analyzed.

"Then..." Lu Ling pondered for a moment: "If the murderer is to steal money and earn more rewards, such behavior is often more impulsive. Money touches people's hearts, and people are actually controlled by money; It can also prove that there is no deep hatred between the murderer and the deceased. Then this murder may be."

"One try." Yan Yu said.

"Yes, according to my analysis, the murderer is a college student with a high degree of education, and has very stable values. He firmly believes in what he recognizes, and he does things directly and firmly. He should not have a stable job. I am overwhelmed by life, but I am in charge of my own life." Lu Ling put forward his own point of view.

"What about age? Gender?" Yan Yu asked.

"The age should be between 20 and 28 years old. I think the probability of gender is 30% for men and 70% for women," Lu Lingdao said.

"You actually prefer female murderers?" Yan Yu hesitated.

"Not necessarily, maybe it's just a bit of a feminine character." Lu Ling added.

"No matter how you say it, you can analyze it to this point, which is already very powerful." Yan Yu said, "Then what do you think is the murderer's motive?"

"Gain the peace of mind." Lu Lingfu blurted out his heart.He didn't even know how he came to this conclusion, but the scene he saw seemed to tell him such an answer.

After Lu Ling finished speaking, Yan Yu thought for a moment: "Tranquility is also a kind of spiritual enjoyment. We saw that the cause of death of the deceased was ice. In fact, many artificial stimulations may excite the nerves. Excitement is a kind of enjoyment. Tranquility is also one."

Seeing that Yan Yu agreed with his point of view, Lu Ling asked a few words by the way: "What exactly is the damage to the human body caused by this kind of stimulation? The murderer was like this in the case I handled before. From a psychological point of view, this is also true. Pursue a kind of compensation, but pathologically?"

"Do you want to talk about physiology? Including ice, noodles, and some artificial stimulation methods will reduce the sensitivity of the nervous system to excitement, damage more nerve cells, and even cause scars. The murderer may be."

"Maybe he knew the crime of the deceased and wanted to do such a thing for the police." Lu Ling took a deep breath.

Although these discussions seem to have no cause and no effect, they are all based on drawing water out of thin air. It is very human to infer behavioral psychology from the details of the scene.

"As you said, the murderer may not have a happy family?" Yan Yu asked.

"No, I even think that the three views that the murderer may have been exposed to in his childhood were all positive. Later, he was influenced by this society and felt that social problems were serious. Or, during his growth, he encountered unacceptable changes and hit."

"Understood." Yan Yu didn't expect Lu Ling to be able to analyze so much.She believed what Lu Ling said, because it was consistent with the situation at the scene.

"How helpful are these reasonings in handling the case?"

"In your name, I will push forward and let the video team investigate in the direction we have approved. Focus on investigating the friends around the murderer. After all, to make this case possible, the murderer and the deceased are likely to be acquainted."

"Okay." Lu Ling nodded.

Yan Yu did not procrastinate at all, immediately went to the leader and reported the situation analysis.

At the same time, Liao Jun's trace evidence analysis has made an interesting progress.

Trace amounts of tetracalcium aluminoferrite, dicalcium silicate, tricalcium silicate and other powders were found at the site.

That is cement.

There is no construction site nearby, and the deceased did not work at the construction site before. Generally speaking, the two women who came here to provide services would not move bricks at the construction site.
In this case, the powder may be on the murderer, that is to say, the murderer may be working on the construction site.

Based on this inference and Lu Ling and Yan Yu's reasoning, the identity of the murderer is likely to be a friend of the deceased who was on the construction site.

This censorship radius has been greatly reduced.

The case was gradually moving towards solving the case, and the young policemen who participated in the assessment gradually began to show their sharpness.
