crime scene

The Huayao dormitory is an old community, and there is no surveillance system installed, and no suspicious persons have been found at the intersections of the surrounding streets.

Before his death, the deceased had exchanged cups with business friends. He drank from noon to almost eight o'clock in the afternoon, and now it is 22:30. The time of death did not exceed two hours, that is, the deceased was killed as soon as he came back.

Under the pillow, a dagger was found, about 30 centimeters long.The shape is like a noble pistol in medieval Europe.

According to legend, as long as you put it under the pillow of an unfaithful man, that person will die quietly in his sleep.

A card was also found under the pillow, the kind that offers special services.

There are marks on the front and back of the business card, which seem to be caused by pinching the thumb and index finger.

What kind of state of mind is he showing when he is holding this business card so hard, or when he is facing the next target?

Hope the killer forgot to wear gloves while performing this maneuver.

Su Nian returned the evidence bag to the investigating police officer.

"How is it? Did you find anything special?" Xie Qian asked.

"The murderer was stimulated."

"kindness?"

"He is excited, agitated, looking for excitement, pleasure, his heart has been extremely distorted, and his behavior has become arrogant. He is provoking the police."

Xie Qian was stunned when he heard that.

"Maybe, I mean maybe, the crime will escalate."

"Wait until we get back to the team for a meeting." Xie Qian patted him on the shoulder, walked out of the room with his arms, and led him downstairs.

"I also feel like he's right there with us."

Su Nian watched him light the Hongta Mountain, took a puff with such force that he seemed to be a little bit ruthless, and let out the smoke in a relaxed manner.

"I feel like our actions are being monitored." Xie Qian continued, his eyes full of fatigue, "First of all, it can't be an internal problem. I believe that my people, the people under my command, all started from one Follow me from the beginning."

Su Nian listened carefully, waiting for him to continue.

"In the past two weeks, the place we have been to the most is the Changyuan Group. I agree with you. The personnel of the Changyuan Group were found to be suspected of committing major crimes."

Go back and read their files seriously, Su Nian thought.

"The business card at the scene should refer to the next victim."

"I don't think so."

The word Su Nian used this time is 'feel'

"In the first case we found a syringe in an inconspicuous medicine chest, in the second case we also found a barbiturate solution in an inconspicuous cabinet, in the fourth case the notice and the dagger were simply put under the pillow together, there was no This shows that the murderer is no longer timid, and this confrontation with the police has made him more daring and arrogant. If this continues, he will very likely regard himself as a god, ignoring the law and the law. Social order is very harmful."

Xie Qian slowly exhaled smoke rings, listened to his analysis logically, and nodded in response from time to time, Wang Ruixue taught him really well.

"Squad, you can accept it!" Yang Wenxuan waved his hand in the distance.

"Okay, go back, your situation is much better than Friday afternoon." Xie Qian opened the car door for him casually.

The escalation of crime means that the suspect is more oriented and targeted when carrying out criminal activities according to all relevant factors such as psychological state, thinking logic, behavior mode, time and place, and has more serious social harm.

That business card is definitely more than that simple.

How will the murderer upgrade?

In this case, there are too many ways to upgrade,

Seeing that there was coffee in the car, Su Nian wanted to drink it, but because of the principle of 'never touch anything that isn't yours', she didn't take it for a long time, she just stared straight at it.

This kid doesn't look right.

Xi Qian thought about it, and asked, "Hey Nian Nian, have you had dinner tonight?"

Su Nian let out a "hmm".

"Just say what you have to say, don't be polite to me, do you hear me?"

Su Nian reached for a bottle of coffee.

Xie Qian couldn't help laughing out loud, and wanted to drink a bottle of coffee after making a fuss for a long time.

Qian Qian misunderstood this matter for many years. Su Nian didn't like to drink coffee because there was only coffee in the car at that time.

He still prefers iced tea to coffee.

Go back to the police force and do your job.

Zhang Yitian and Chu Duanyu entered the forensic anatomy room together, Jiang Panpan checked the business card, the others ate and drank to fill their stomachs, and Su Nian carefully studied the personnel files in Xiqian's office.

This autopsy was the longest one that Chu Duanyu had done, and it was so long that the identification department had not come out of the autopsy room until the results came out.

The basic autopsy report didn't come out until after three o'clock in the morning, and the sleepy police officer was quickly called up for a meeting.

In the conference hall, most people looked like their upper and lower eyelids were fighting.

Xie Qian rubbed his eyes and slapped the table. This stimulation was enough to keep the group awake for a while.

"It took a long time for the forensic medicine department to determine the cause of death, although the result was unexpectedly simple." Chu Duanyu reported, "The blood urea nitrogen content of the deceased exceeded 15 mg%, and the respiratory center was paralyzed for a long time. Caused death, because the deceased drank too much alcohol, which accelerated the poisoning process of barbiturates. Except for the needle hole in the neck, the deceased had a slight impact injury on the forehead, which did not seem to be caused by a beating , should be walking unsteadily, the report is over."

"The Identification Department's identification of the business card is like this. A small amount of chemical reaction was found on the bending deformation of the business card. It is a rubber glove, a medical rubber glove." Jiang Panpan put the business card on the table.

"Nian Nian, your deduction."

Su Nian repeated what she said to Xie Qian at the scene.

"Crime escalation, what is the specific escalation method?" Feng Li touched the bar and asked.

Su Nian replied, "The details are not clear, this is just a speculation."

"You are speculating again, can you come up with specifics?"

"What are the specifics! He is not the murderer who knows what the murderer wants to do next. It is very good to be able to profile to this point. The general direction is provided, and the rest can use your brain, huh?"

As soon as Xiqian opened his mouth, Feng Li had no choice but to keep his mouth shut and nod his head.

Can this maintenance be any more obvious?

"Okay, let Yang Wenxuan fish out the pimp on the business card first, let's take a rest for nothing, wait for the notification if there is something to do, and the meeting will end."

The previous screening of company personnel was too absolute and too idealistic, and there was some element of gambling in it.

Su Nian remembered Wang Ruixue once said that the front-line detectives hold not only justice, but also the weight of life. If you choose to trust the judgment of the profiler, if you make a mistake...you will be spit on and feel guilty Fuck it!

After all, before the case is finalized, those people have certain suspicions, and it is fine to bring them here for questioning.

Xiqian really planned to do so.

Su Nian has nothing to do, people who should be busy are busy, and the leisure at this time makes him distracted inadvertently.

He didn't feel sleepy at all, but the tingling pain in his abdomen forced him to frown.

He didn't want to say it out, firstly because he was afraid of trouble, and secondly because he was afraid of causing trouble to Qianqian, so he had to lie down on the table and rest for a while.

Xie Qian only thought that he was sleepy, put on some clothes and continued to work.
