"You're from the archives, right?"

I looked at Deng Min incredulously and asked, I remember, I went to look up the archives before and saw it.

Deng Min nodded slightly, and I suddenly felt bitter in my heart, and looked at Yang Wen, who deliberately didn't look at me.

Deng Min clapped his hands a little embarrassedly and pulled my thoughts back.

"The deceased, Lu Ming, who was 178cm tall and weighed 75 kilograms, was a high-level executive of a well-known security company in the city. The time of the murder was between 5 and 8 o'clock on Wednesday evening, the cause of death was excessive blood loss through the heart, and the murder weapon was preliminarily determined to be a knife about 5cm wide and about 25cm long. ”

Just as Deng Min was talking, Jiang Xu walked into the office of the special case team and quietly sat beside Su Yang.

Deng Min saw Jiang Xu coming in, paused, and continued.

"We visited the neighbors in the community and some vendors around, and at about six o'clock in the time of the crime, someone saw Lu Ming and talked to him, and after Lu Ming went home, he never went out again, that is, after Lu Ming returned home, someone went to his house and killed him. ”

After Deng Min finished speaking, he glanced at Jiang Xu, Jiang Xu opened the report in his hand and said in a cold tone.

"Zhou Jie's autopsy report came out, the murder should have been between 5 and 8 o'clock yesterday evening, and Lu Ming's heart penetrated and died of excessive blood loss, according to the wound, the murder weapon that killed Zhou Jie and the murder weapon that killed Lu Ming should be the same, judging from the death of the deceased and the modus operandi, the murderer is the same person. After Jiang Xu finished speaking, he glanced at Deng Min again.

Deng Min nodded and said.

"The deceased, Zhou Jie, was 180cm tall and weighed 75 kilograms, and was a psychiatrist. At five o'clock yesterday afternoon, Zhou Jie got off work and bought two vegetables at the small restaurant in front of his house, and then went home, never going out. ”

After Deng Min finished briefing the two deceased, everyone fell silent.

Su Yang sighed deeply and opened his mouth faintly.

"The murderer must have been planning for a long time. As soon as Su Yang's words came out, everyone looked at him with interest.

"Lu Ming and Zhou Jie are not in the same unit, although the work of the psychiatrist is usually fixed, but it is unavoidable, every day after work can be on time or there will be no emergencies due to the patient's reasons; not to mention the security company, there may be a task at any time, which causes more uncertainty in time, so the murderer must have waited for a long time, or in fact, the murderer has tried many times, but because of the problem of time, many opportunities have been missed. ”

Su Yang's analysis is not unreasonable, for a murderer, to kill two well-trained seven-foot men, not only need calm means, but more importantly, there must be a relatively stable and safe environment, with this premise, it is possible to minimize the possibility of murder failure.

Jiang Xu nodded and glanced at Su Yang appreciatively.

Su Yang understood and smiled.

Jiang Xu continued to add.

When the murderer sees a large amount of blood stains at the scene, he will habitually clean up the scene, and even let go of even small cracks, or it can be said that as long as the dirt appears in the murderer's eyes, he has to clean it up. ”

After Jiang Xu finished speaking, a capable young man sitting opposite suddenly opened his mouth to ask.

"Could it be that the murderer was worried about leaving some information to clean up the scene?"

The young man who questioned was Yang Wen's apprentice Wu Lei, who had made two third-class meritorious services at a young age and was a good seedling of the police force.

Jiang Xu did not rush to answer this question, but took out the clothes worn by the two deceased when they were killed from the evidence brought back from the scene.

"You see, these two bloody clothes are the clothes worn by the two deceased when they were killed, and the forensic evidence has also confirmed that the clothes are stained with the skin fibers of the deceased, if the murderer cleaned up the scene in order to eliminate the traces, then the most important thing to clean up is these two clothes, because in order to kill the two deceased, the murderer must be close to the deceased, and in the process of committing the crime, the murderer is most likely to leave traces on these two clothes. However, the murderer not only did not take the bloody clothes, but also put them in the washing machine, which is a common escape psychology, the bloody clothes will not make him feel uncomfortable as long as they are not in his line of sight, and the washing machine is the best place to put the bloody clothes, in his subconscious, the dirty clothes will become clean as long as they are put in the washing machine. ”

After Jiang Xu finished speaking, he looked at the few people in front of him, and they all had expressions on their faces that seemed to understand whether they understood or not.

Su Yang had already thoroughly understood what Jiang Xu meant, and he nodded.

Jiang Xu continued.

"I have seen the wardrobes of the two victims, probably because of professional habits, the clothes that the two victims usually wear are basically light colors, and the murderer did not choose the clothes for the victims from the clothes that the victims often wear, but chose clothes from the clothes folded up by the victims in the drawer for them to change. ”

Jiang Xu got up and found the photos of Lu Ming and Zhou Jie at the scene of the crime from the photos on the table.

"You see, the clothes that the two deceased changed were with complex and obvious patterns, this is not a coincidence, but the murderer's subconscious choice, the reason why he chose this way is because the patterns of these two clothes can well cover the small amount of blood that flowed out after the victim changed his clothes, just from the photo, if you don't observe carefully, you can hardly see the bloodstains, which shows that the murderer has a habit of cleanliness, and extends to the category of severe obsessive-compulsive disorder. ”

Jiang Xu's analysis is almost perfect, which is also the most important part of the psychological analysis when analyzing the case.

Su Yang was amazed by Jiang Xu's meticulous thinking, his high understanding of psychology, and his own forensic doctor, Su Yang couldn't help but admire Jiang Xu in his heart.

Jiang Xu walked to the table, picked up a pen, and began to write on the blackboard.

"The murderer is male, between 155cm and 170cm tall, thin, right-handed, with quick thinking and meticulous logic, with cleanliness with severe obsessive-compulsive disorder, and overconfident and even conceited. The murderer had a deep understanding of medicine or was engaged in medical-related work. ”

For mediocre people, the thinking and logic of people who may be too good or talented are incomprehensible to them, just like now, Deng Min and Wu Lei are looking at Jiang Xu in confusion.

Only Su Yang and Yang Wen unconditionally accepted the outline of the murderer depicted by Jiang Xu.

"Can this height and figure kill two tall men?" Sure enough, Deng Min objected.

Jiang Xu's face suddenly became a little irritable, but he didn't have a seizure.

He pointed to the autopsy report in his hand and motioned for everyone to look at it.

Deng Min and Wu Lei stared at the autopsy report for a long time, but they didn't see any reaction.

Yang Wen blushed a little and shook his head helplessly.

Seeing that Jiang Xu's mood was a little bad, Su Yang hurriedly explained.

"It's because of the knife edge, the autopsy report is very clear, the knife edge is from the bottom up, and part of the handle of the knife is inserted into the heart together with the knife body, which shows that the murderer's height must be shorter than the two victims, and the strength is not great, in order to make the knife completely penetrate the heart, the murderer exerted a lot of strength, and this situation will occur, you see. ”

Su Yang flipped the pages of the autopsy report and continued.

"The wound on Zhou Jie's heart has been repeatedly contused, that is to say, the knife has been displaced after being inserted into Zhou Jie's heart, but not when killing Lu Ming, which shows that the height of the murderer is just right for killing Lu Ming, but it is a little difficult to kill Zhou Jie, according to this situation, the estimated height range of the murderer is between 165cm and 170cm. ”

After Su Yang explained, Deng Min and Wu Lei suddenly realized.

Su Yang looked at Yang Wen a little depressed, and suddenly felt that Yang Wen had dug a pit for himself to jump, according to the current situation, the special case team was equivalent to only Yang Wen, him and Jiang Xu, and their workload was much larger.

Thinking like this, Su Yang's eyes inadvertently glanced at the two cross-stitches on the table, and suddenly spoke again.

"That's right, these two cross-stitches. Su Yang displayed two cross-stitches in front of everyone.

"The two cross-stitches were taken down from the wall of the living room of the two victims' homes, and the initial speculation is that they were left by the murderers. ”

Several people came to the cross-stitch, and Yang Wen looked up at Su Yang, waiting for him to explain further.

Su Yang turned his head to look at Jiang Xu, and Jiang Xu immediately spoke.

"These two cross-stitches were hung on the wall of the victim's house at a low position, and the murderer should have hung them directly on the ground while standing on the ground. And after the two cross-stitches were taken down, there were only a few traces on the wall of Lu Ming's house, but there were no traces on the wall of Zhou Jie's house, which shows that the cross-stitch of Lu Ming's house was hung for longer than the cross-stitch of Zhou Jie's house. And ......"

Jiang Xu straightened up, as if he was explaining to Su Yang at Zhou Jie's house, and pointed to several places inside the two cross-stitches.

"The workmanship of the two cross-stitches is too rough and unprofessional, and there are leaks, threads, and wrong stitches, which further shows that the two cross-stitches were not specially bought by the victim for decoration. Jiang Xu finished speaking in one breath, and then stopped talking.

Yang Wen stood up and made a simple arrangement with everyone.

Deng Min and Wu Lei conducted an investigation in and around the community based on the outline of the murderer, while Su Yang was responsible for conducting a thorough investigation of the backgrounds of the two victims.

What Su Yang didn't expect was that Yang Wen actually put Jiang Xu in a group with him and asked Jiang Xu to investigate the case with him.

Su Yang originally thought that Jiang Xu would refuse, after all, Jiang Xu was a forensic doctor, and it was not his job to investigate cases in the field, but Jiang Xu himself did not raise any objections and accepted it happily.

At the end of the meeting, Su Yang also went to find Yang Wen, he was worried that arranging Jiang Xu to go out to investigate the case would cause Jiang Xu's dissatisfaction, after all, the salary was dead.

But Yang Wen only told Su Yang that he didn't know Jiang Xu well enough, and if he went out with Jiang Xu to investigate the case, he would gradually understand what kind of person he was.

Su Yang felt that it was easier to work with Jiang Xu by his side, after all, Jiang Xu's knowledge was very rich, and his logical analysis and reasoning ability was also very good.

Thinking of working with Jiang Xu for a few days, Su Yang frowned, he always felt that Jiang Xu had some unknown secret in his heart......
