Wang Tao yawned and approached the physical evidence class, and when he looked up, he saw a large one dangling in front of him, which turned out to be Xun Keran, who was sitting on a high chair with cocoa milk in his mouth and still restless.

Wang Tao: What are you holding in your mouth?

Cocoa: Milk.

Wang Tao: When I didn't ask.

Mr. Wang dragged his tired body inside, he didn't go home at all last night, and the physical evidence retrieved from the subway station was ranked at more than 900 just by the sorting number, which had already broken the record for the amount of physical evidence in a single case he was responsible for so far. After finishing the serial number and checking it again, the takeaway on the road had already shouted, so even in the face of the demon Coco in front of him, Mr. Wang with black circles no longer had the extra energy to deal with it. But when you only ask for peace, some people don't give it.

Xun Keran jumped off the high chair and followed behind Wang Tao step by step, Teacher Wang, Teacher Wang, I bought you potato chips and cocoa milk.

Thanks, are you going to chase me? Wang Tao replied unconsciously.

If I don't chase you, the demon Coco is wagging his tail, and besides, I know that you are facing a huge amount of physical evidence this time, and I am here to help!

Wang Tao finally stopped, turned around and looked at her, are you really Xun Keran? No way, did you go on vacation for a few days and were repackaged?

Coco's head was shining with the light of a little angel, how could it be, Mr. Wang, don't refuse the kindness of others.

Wang Tao has lived for more than 30 years, not to mention reading countless people and reading countless things, although there is no logic in this, but as a human being, his intuition tells him that this girl in front of him either has a despicable purpose or her brain has been broken and reloaded, and he stares at Xun Keran with his self-righteous sharp eyes, wanting to see through the true face of the demon.

Coco and Wang Tao's dark circles looked at each other for a few seconds before shrugging, Well, it's not a big deal, the director said that I asked for leave without authorization and asked me to write a 10,000-word review.

So?

The little angel raised the potato chips in his hand and said with a smile, I heard that Mr. Wang, your writing is excellent, and no one in the Public Security Bureau dares to call it second.

Wang Tao rubbed his forehead, life is really difficult.

"I said, don't you have anything to do in the forensic department? And who, Zhou Wenyong's corpse? ”

Xun Keran just smiled at Wang Tao, she didn't argue. Zhou Wenyong's autopsy was completed overnight yesterday, the condition of the body was very simple, the chest stab directly led to his death, in addition to the examination of the entire corpse, Coco only came to one conclusion: if it were not for this knife, Zhou Wenyong's healthy organ body would have lived to at least sixty years old.

It's a pity that the "if" can't match the "reality", everyone who is alive and well will not think about whether they can live until tomorrow.

The only thing that made Coco pay attention was that before the autopsy, he first checked the clothes worn by Zhou Wenyong, except for a blood hole in his chest, there was a vague palm print in the area behind the clothes, which was the trace left by the murderer's right hand stabbing with a knife and hugging Zhou Wenyong's back with his left hand. Now this palm print has been transferred to the computer for further detailed analysis.

Wang Tao was busy with the book of physical evidence registration in his hand, glanced at Xun Keran, and guessed a rough idea, "The autopsy is ready?" Do you know the murder weapon? ”

"A small knife, about 7-10 centimeters long and no more than 3 centimeters wide, sharp, similar to a small fruit knife."

Wang Tao stopped his movements, "So short? I've seen the wounds of corpses, not shallow, right? ”

"That's because the hard stab squeezed Zhou Wenyong's body from behind at the same time, causing a wound that was much deeper than the length of the blade." What she didn't go on with was that the killer used so much force that the handle of the knife left a clear circular mark on the skin through the clothes.

"Did you find anything with them at the scene yesterday?"

Wang Tao's words drew Coco's attention back, "The suspect stood motionless in a corner of the subway station before the murder until Zhou Wenyong walked into the subway station. ”

"So the purpose is clear, is it to kill Zhou Wenyong?"

"It's not the strangest thing, this guy is standing in front of him, looking at a decorative wall, but in fact, he is the one who observes the blind spot behind him through the small reflective mirror on the decorative wall."

"Who?" Wang Tao was clearly intrigued.

Xun Keran showed an appetizing smile, and then shrugged, "I don't know." ”

Wang Tao has become accustomed to Xun Keran's unrelated behavior, and he is even too lazy to get angry.

"The man he was looking at was the first person to scream in the subway." Xue Yang exuded a tired aura and appeared at the door of the Physical Evidence Section faintly, "Let me ask if there is any progress in the Physical Evidence Division?" We lined up for testimony all night, and there were too many different accounts. ”

According to the suspect's line of sight, Xue Yang found the testimony of a person named Sun Mei at the scene. Sun Mei was sitting on a bench in front of the subway shopping street, which was also the area where the suspect could see through the reflection of the decorative wall, but it was Sun Mei's testimony that really caught Xue Yang's attention.

[I sat on a bench and watched my son play, and there was a young woman sitting next to me]

[Ouch, that woman is scary, let me tell you, she was so nervous, I casually called my son's name, and she jumped up in fright]

[Also, don't say I said it, I see it...... The woman had a knife hidden in her bag! The blades have cut the bottom of the bag.]

[Oh, one more thing...... Before everyone was in a mess, the woman ...... It was the first to scream! Yes, that's right, when nothing happened, she screamed, and the scream was terrifying, eh, was it the confusion caused by this woman's scream? 】

Coco heard the sound of Wang Tao swallowing saliva, and she knew what Wang Tao was thinking by looking at her expression: How much more physical evidence will be produced if the knife goes down? ?

Xun Keran patted him, and the bloody physical evidence belonged to the forensic department.

"The woman Sun Mei saw, through the camera anti-tracking investigation, is named Qian Zixuan, and she is a very ordinary young female white-collar worker." Xue Yang threw his body into the stiff sofa of the Physical Evidence Division, glanced at it, and stopped firmly on a bottle of Coke on the table. I don't know why, he usually doesn't love snacks, and he is very eager for the taste of ice cola at the moment.

These details were properly seen by the sharp-eyed Xun Keran, who sighed silently and handed the Coke over. These guys who are police officers are reluctant to go for physical examinations every year, because every time they have a physical examination, they will be caught by the doctor for a period of fierce training, with irregular meals, staying up all night, high pressure, and smoking.

"Let's sort it out, the most concerned thing in the physical evidence now is naturally the small jewelry box that was soaked in blood."

"We found out that the jewelry box came from the stall set up by the homeless Lao Du at the subway entrance. He recalled that Zhou Wenyong accidentally stepped on something when he passed by his stall about a few minutes before the accident, so he bought a small hairpin in the shape of a leaf, and Lao Du personally put the hairpin into the pink jewelry box for him. But the guy said that he only remembered so much, and if he asked more, he would cry out that it hurt, and he kept asking who would compensate for his injury. ”

Coco fumbled with the unopened treasure bead in his hand, "According to what you know now, there is a very smooth reasoning, Zhou Wenyong went to the subway to go on a date, and the date object was Qian Zixuan, before getting off the subway station, he bought a hairpin at Lao Du's stall, and before he got off the subway station, he was stabbed to the ground by the murderer before he met with Qian Zixuan, and at this time, Qian Zixuan, who had already seen him, noticed the murder before anyone else, so he was the first to scream. ”

Xue Yang almost drank all the Coke in one breath before stopping, "This is the same as our reasoning last night, but there are a few points that don't make sense, the first is why Qian Zixuan has been nervous, and even prepared a knife?" The second is who the murderer is targeting......"

"The murderer's target? Who else could it be besides Zhou Wenyong? Wang Tao frowned and interrupted Xue Yang's words, "If his target is Qian Zixuan, then why don't you do it after waiting in the subway station for so long?" ”

"Some people kill to kill, and some kill people to torture the living." Xue Yang couldn't remember where he heard this sentence, but this sentence suddenly appeared in his mind at this moment, and he instantly blinded everyone around him, and even Xue Yang himself couldn't help but hesitate, why didn't he think of it before.

In order to torture Qian Zixuan, the murderer hid in a dark corner and observed her, and then killed her date...... Quite reasonable. Coco followed Xue Yang's logical analysis, and Wang Tao, who was originally questioned, also felt as if the path was deep and quiet, and saw another possibility of the truth, the murderer was likely to be Qian Zixuan's ex-boyfriend or enemy.

But in Xue Yang's mind, another meaning slowly came to mind, Sun Mei's testimony mentioned Qian Zixuan's nervousness and the knife hidden in her bag, which meant that she might know...... Will something dangerous happen?
