That is, Wang Jian is hiding too well, and Su Tong, as a psychologist, may be able to see something from it and give him a little advice.

Su Tong wrinkled her nose, recalled the impression that Wang Jian gave her before, and said half-jokingly, "What should I do, now my mind is full of scenes of Wang Jian holding flowers and driving a luxury car waiting for me at the door." ”

Xu Sa, "......"

"Haha, just kidding." Su Tong couldn't help but smile, "Wang Jian, that person, seems to be good-tempered, but from his clothes and some details, it can be seen that he has a very serious obsessive-compulsive disorder. ”

"People with obsessive-compulsive disorder generally have a paranoid personality and can't be too easy-going, which is a huge deviation from the gentle image he tries to show."

But this deviation is not clear whether he is subconsciously hiding it in front of outsiders or to cover up some facts.

"Whew......" Xu Sa sighed, "This case is really tricky." ”

After speaking, he secretly glanced at Su Tong's side face, and silently thought in his heart, when this case is over, should he take some time to make an appointment with Su Tong.

At the very least, send a bouquet of flowers or something......

The two walked side by side, analyzing the case with and without a pair.

"Coincidentally, I was about to go downstairs to look for you." As soon as the two of them walked upstairs, they collided with the oncoming Chen Lao.

Chen Lao shook a bag of information in his hand, "This is the autopsy data of the victim of your case." ”

"Old Chen, it's amazing, I knew you were almost out here." Xu Sa complimented him and hurriedly took over the information.

Chen Lao took off the eyes on the bridge of his nose, and glanced at Xu Sa while wiping, "Hmph, just say pretty things, compared to this, you better hurry up and catch these lawbreakers." lest I get some corpses and embarrass me, an old man. ”

Su Tong, who stretched out his head and squeezed Xu Sa together, was slammed in his heart, and said in some surprise, "Old Chen, what did you mean just now that this case may be a serial murder case?" ”

Chen Lao sighed, and simply turned around and leaned against the wall on the side, "On the surface, the deceased was stabbed twenty-three times, and the murderer should be a vengeful impulsive murderer." ”

Su Tong and Xu Sa nodded, that's right, after the two of them saw the crime scene at that time, they also thought that the murderer should be an impulsive crime.

"But I found a little bit on the body." A solemnity flashed in Old Chen's eyes, "Among the twenty-three knives, one of the knives directly hit the heart, and the wound was very straight and neat. Do you know what that means? ”

"This means that the person who does it knows a lot about the anatomy of the human body and may even have the experience of committing a crime. If my conjecture is true, it is very likely that the knife wounds on the deceased's body, the twenty-two stabs except for the fatal one, were just disguised by the murderer. ”

A very calm murderer who deliberately disguises the case as an impulsive crime.

Thinking of this, Xu Sa and Su Tong subconsciously glanced at each other, if this was the case, the murderer's purpose was very obvious, in order to disrupt their investigation sight......

And the murderer also achieved this goal.

"But what I just said is just my guess." Elder Chen rubbed his temples, "You know, as a forensic doctor, I can only use the data on the corpse to speak, and I can't give you too much advice. ”

Forensic doctors sometimes have a very big impact on investigators, so they can't say much.

Xu Sa nodded understandingly, "Thank you, Old Chen, these have helped us a lot." ”

"Well, that's just a basic cause of death verdict." Old Chen yawned, "After that, I will send the detailed other data to the kid named He He from your serious crime team." ”

With that, he turned around and went into the medical examiner's office.

In the corridor, the warm winter sun sprinkled in, but Xu Sa and Su Tong couldn't even feel the slightest temperature.

"Xu Sa, I want to go to Jiang Li's house again." She wanted to personally verify Chen Lao's guess.

Xu Sa didn't say anything, and even took Su Tong to Jiang Li's house.

Because the case has not been solved, the door of Jiang Li's house is wide open, and there is a cordon outside, and there are still traces of blood on the belt.

The community where Jiang Li lives is already small, and now it looks more and more deserted and cold.

The two put on gloves and shoe covers, bent over and walked through the cordon.

Although all the evidence in it has been collected, it is inevitable that there will be missing or new clues.

Su Tong stood in the center of the room, glanced at the layout of Jiang Li's house, took a deep breath, and began to analyze Jiang Li.

Xu Sa knew what she was going to do, so he stood aside and didn't disturb her.

Jiang Li's home is rich in colors, and there are a lot of European and American style decorations, which can be seen that she is a woman with a very delicate mind and personality.

She had seen Jiang Li's dress in Siqian before, it was a very delicate nightgown with limbs, and judging from the remaining aromatherapy found in her house before, Jiang Li should have a long-term and stable boyfriend.

Thinking of this, Su Tong received the shoe cabinet in Jiang Li's house and opened the shoe cabinet.

The shoe cabinet is very neatly arranged, and all kinds of shoes are placed in separate rows, and the colors are also sorted.

Looking at such a scene, Su Tong was stunned.

"This Jiang Li, does he also have obsessive-compulsive disorder?" Xu Sa on the side raised his eyebrows.

"That's not right!" Su Tong shook his head, "Something is wrong with this house!" ”

"What's wrong?" Xu Sa also followed Su Tong's footsteps and looked at the entire room, "I think it's quite right." ”

Su Tong closed his eyes, trying to grasp the clue that flashed in his mind just now.

"Xiaotong, don't worry, take your time." Seeing her anxiety, Xu Sa said softly, "I'm here to accompany you, you can stay here as long as you want, so don't worry." ”

With Xu Sa's words, Su Tong gradually calmed down.

She took a deep breath and spoke, "Okay, let's talk about Old Chen's guess first." Previously, our clues about the death of the corpse and the blood splattering pointed out the killer as an impulsive crime of revenge. ”

Xu Sa nodded, that's right, they did qualify and check it out like this.

But Chen Lao reminded us that those are most likely just illusions created by the murderer. Look at this room, it's so neat and clean......"

Aside from the blood on the ground, it was as if nothing had happened to the room.

"This contradicts the characteristics of impulsive crimes." Impulsive crime refers to the murderer's temporary intention, and another characteristic of such a case is that the time period when the murderer committed the crime, the crime scene will be relatively messy.

Because after the murderer is impulsive, all that remains is panic, and under the panic, it is impossible to deal with the crime scene.
